    5 Articulation device. Object of the invention.
    The present invention relates to an articulation device. 10 Background of the invention.
    Joints are known which comprise an elastically deformable element that acts as an articulation between two or more parts associated with said element.
    Normally, the deformable element comprises a part of weakened or narrowed material to facilitate its deformation by bending. This part of weakened material
    or narrowed it constitutes the point or axis of articulation of the joint.
    20 This type of joints allows to obtain a total stiffness in all dimensions except in the axis of articulation. The absence of bearings and similar elements minimizes friction produced in the joint, as well as possible oscillation movements between the articulated parts.
    25 Therefore, these joints are especially indicated when it is necessary to obtain turning movements between several pieces at short intervals and with the least friction and with the greatest possible precision.
    30 However, the deformation of the deformable element when using these joints causes a torque derived from the resistance force to the elastic deformation of the material constituting the element, which tends to recover its original non-deformed shape (resting position). This torque increases linearly with the deformation of the element, and is problematic when the joint is used to lead to
    35 make very precise measurements or when it is necessary to carry out a very


    precise through it, since it introduces a distortion element that can alter the desired results.
    Therefore, an articulation of the type described above would be desirable that,
    5 within a given angular range of rotation of the joint, allowcounteract the torque caused by the force of resistance to elastic deformationof the deformable element. That is, an articulation in which theresulting torque variation within said angular range of rotation is zero.
    10 This will allow a joint to be obtained which, within a angular range of rotation, produces virtually no friction or resulting torque. Description of the invention
    The objective of the present invention is to solve the drawbacks of the devices known in the art, by providing an articulation comprising a first part, a second part and a third articulation part connecting said first and second parts, the third comprising joint part an elastically deformable zone whose deformation
    20 allows the relative movement of the first and second parts around said elastically deformable zone, characterized in that the first part comprises at least a first magnetic element and the second part comprises at least a second magnetic element, said said arrangements being arranged at least a first and second magnetic elements to interact with each other so that the
    The interaction of said magnetic elements creates a resultant force pair around the elastically deformable zone that has an opposite direction to a resultant force pair generated by the elastic deformation resistance force of the elastically deformable zone around said elastically deformable zone , the absolute values of each resulting torque being
    30 essentially equivalent within a controlled angular range of said articulation device.
    Preferably, the elastically deformable zone comprises a flexible deformable part of the third part.


    Also preferably, the flexible deformable part comprises a narrowing of the third part.
    Advantageously, the third part comprises two circular cavities arranged5 symmetrically on each side of the narrowing.
    Also advantageously, the third part comprises two pieces.
    According to an embodiment of the present invention, the at least one first magnetic element 10 and the at least one second magnetic element are arranged facing each other.
    Preferably, the at least one first magnetic element and the at least one second magnetic element are arranged in mutual attraction.
    According to an embodiment of the invention, the at least one first magnetic element comprises two magnets arranged in the first part and each arranged on a side opposite each other with respect to the deformable zone, and the at least a second magnetic element comprises two magnets arranged in the second
    20 part and each arranged in a corresponding position with respect to each magnet of the first magnetic element.
    Thanks to the features described, the present invention allows to obtain a joint that, thanks to the use of the described magnetic elements, has an angular range of rotation in which the resulting torque produced by said joint is nominally zero. That is to say, the use of magnetic elements configured and arranged in an appropriate manner makes it possible to counteract the torque produced by the elastic deformation of the material constituting the joint in an angular range of rotation of said joint, thus obtaining an articulation with
    30 friction and zero torque.
    Such a joint will be especially indicated for its application in devices or experiments in which minimal friction or pairs derived from the use of the joint are required, as well as in devices with joints with
    35 static requests.

    Description of the figures.
    In order to facilitate the description of what has been stated above,
    5 attached some drawings in which, schematically and only by way of non-limiting example, a practical case of realization of the articulation of the invention is represented, in which:
    - Figure 1 is a schematic perspective view of a joint according to the present invention;
    - Figure 2 is an indicative graph showing the relationship between the pairs created by the different elements that are part of the joint of the present invention and the angle of rotation of said joint;
    15 - Figure 3 is a diagram of the forces present during the operation of the joint; Y
    - Figure 4 is a graph like that of Figure 2 of a specific example of articulation according to the invention. Description of a preferred embodiment.
    Figure 1 shows a perspective view of an embodiment of a
    Articulation device according to the present invention. This embodiment comprises a first part 1 and a second part 2 each comprising a prismatic body of rectangular plan.
    The first part 1 and the second part 2 are joined together by their central part
    30 by means of a pair of pieces 3 attached to said parts 1, 2 in the central part of their respective long side faces (only one of the pieces 3 is fully visible in Figure 1).
    Each piece 3 consists of a plate with a rectangular contour arranged in a perpendicular plane with respect to the upper and lower surfaces of the parts 1,


    2 and parallel with respect to the long side faces of said parts 1, 2.
    Each plate 3 comprises two cavities 4 that extend as a channel from its outer perimeter to the central part of the plate along the same axis
    5 longitudinal and ending in a semicircular wall, said cavities 4 forming a narrowing 5 disposed therebetween whose cross section has a minimum dimension in its central zone Z. The narrowing 5 is located in the central part of the plate 3 and is shaped Hourglass
    10 The two plates 3 are arranged at the same level along the longitudinal axis of parts 1 and 2, and are separated by a distance approximately equivalent to the width of each part 1 and 2. The central points of the two central zones Z of each narrowing 5 are arranged along an X axis that is perpendicular to the planes in which the plates 3 are arranged.
    The two plates 3 will preferably be made of a material with adequate elasticity and strength, for example, aluminum or steel.
    In this way, by means of the described arrangement, an articulation is obtained in the
    20 that the first part 1 and the second part 2 are articulated with each other through the two pieces 3. More specifically, considering, for example, that the second part 2 is a fixed part, the first part 1 can oscillate with with respect to the second part 2 (see arrows in the figure) around the central point of the central zone Z of each narrowing 5 of each piece 3, that is, around the X axis.
    The narrowing 5 of each piece 3 constitutes a weakened area of smaller cross-section of the plate 3, so that any flexural deformation of said plate 3 will occur in said narrowing 5, more specifically, in the central zone Z of the narrowing, which is the part of narrowing 5 that has a
    30 smaller cross section. Therefore, the two central points of the central zone Z of the narrowings 5 of each plate 3 constitute the X axis of geometric articulation of the joint of the present invention.
    This implies that, each time the first part 1 oscillates with respect to the second part 2 around the X axis, the narrowing 5 of each plate 3 deforms flexurally.


    For example, in Figure 1, if the first part 1 oscillates clockwise with respect to the second part 2 around the X axis, the two narrowings 5 will deform by bending in the same direction, that is, the upper part of each 5 narrowing 5 will oscillate clockwise with respect to the lower part of each narrowing 5. This deformation of each narrowing 5 will cause the appearance of a force of resistance to elastic deformation in each narrowing, caused by the tendency of the elastic material in which it is conformed each narrowing 5 to recover its original form or its resting position (in this case,
    10 the position shown in figure 1). This resistance force to the elastic deformation present in each narrowing 5 will cause the appearance of a force pair that will oppose the oscillating movement of the first part 1 clockwise, that is, will cause the appearance of a force pair in the anti-sense direction. schedule around the X axis.
    15 In other words, each time the first part 1 oscillates around the X axis, it is necessary to overcome a reaction force caused by the elastic deformation of the two narrowings 5, which tends to return the joint to its rest or equilibrium position ( in this embodiment, the position in which the first and second
    20 parts 1, 2 are arranged in parallel with each other, shown in Figure 1).
    Referring again to Figure 1, the first part 1 of the joint comprises two holes 6 of circular section therethrough which extend perpendicularly with respect to the upper and lower faces of the first part 1.
    The holes 6 are arranged aligned along a central longitudinal axis of the first part 1 and in an opposite and symmetrical manner with respect to the transverse intermediate axis of the first part 1 (parallel with respect to the X axis), at a certain distance of said intermediate axis.
    30 Inside each of said holes 6 a disk-shaped magnet 7a, 7b is fixed with a contour that corresponds to that of the circular inner walls of the hole 6. Each magnet 7a, 7b is placed inside the hole 6 so that one of its faces (in this embodiment, the lower face) is arranged in the same plane as the lower face of the first part 1.


    The second part 2 also comprises two holes 6 and two magnets 7a, 7b correspondingly arranged as previously described in the case of the first part 1, although, in this case, the two magnets 7a, 7b are placed with their upper face arranged in the same plane as the upper face of the second part 2.
    5 Therefore, in the 0 degree rotation state of the joint shown in Figure 1, the magnet 7a of the first part 1 located on the side of the central transverse intermediate axis of said first part 1 is arranged facing the magnet 7a of the second part 2 disposed on the same side of the central transverse intermediate axis of
    10 said second part 2, at a distance d thereof, symmetrically with respect to a parallel plane with respect to the lower and upper faces of the first part 1 and the second part 2 and passing through the central point of the central zone Z of each narrowing 5. Also, the magnet 7b of the first part 1 located on the other side of the central transverse intermediate axis of said first part 1 is arranged
    15 facing the magnet 7b of the second part 2 disposed on the same side of the central transverse intermediate axis of said second part 2, at a distance d thereof, also symmetrically with respect to a parallel plane with respect to the lower faces and upper part of the first part 1 and the second part 2 and passing through the central point of the central zone Z of each narrowing 5.
    20 Magnets 7a, 7b and magnets 7a, 7b of the first and second parts 1, 2 are arranged in mutual attraction. That is, the magnet 7a of the first part 1 and the magnet 7a of the second part attract each other, and the magnet 7b of the first part and the magnet 7b of the second part also attract each other. Also, the strength of
    The attraction between the magnets 7a is equivalent to the force of attraction between the magnets 7b for the same separation distance between the corresponding magnets.
    The function of these magnets 7a, 7b is described below.
    30 When the first part 1 of the joint shown in Figure 1 oscillates clockwise, it will rotate around the X axis and the narrowings 5 of the respective plates 3 will be bent correspondingly. This deformation will cause the appearance of the elastic deformation resistance force described above, which will create a force pair in the opposite direction (counterclockwise direction) around the
    35 X axis.


    At the same time, the oscillation of the first part 1 clockwise around the X axis will cause the magnets 7b of each part 1, 2 to approach each other and will cause the magnets 7a of each part 1,2 to move away from each other.
    5 The more the first part 1 rotates with respect to the second part 2 around the x-axis clockwise, the greater the resistance force to the elastic deformation produced in the narrowings 5, the greater the attractive force between the two magnets 7b , which increases as magnets 7b approach each other, and smaller is
    10 the force of attraction between the two magnets 7a, which decreases as the magnets 7a move away from each other.
    In other words, the more the first part 1 rotates with respect to the second part 2 around the X axis clockwise, the torque created in the
    15 narrowings 5 (anti-clockwise), increases the torque created by the attraction of the magnets 7b (clockwise) and decreases the torque created by the attraction of the magnets 7a (anti-clockwise).
    The foregoing is equally applicable if the first part 1 of the
    20 joint oscillates counterclockwise, producing the same effects, although in reverse. Reference is made below to the graph of Figure 2. This graph shows the relationship between the angle of rotation of the joint, or the angle of rotation between the first part 1 and the second part 2 (horizontal axis, in degrees) and the torque value created by
    25 the magnets 7a, 7b and by the narrowings 5 of the plates 3 (vertical axis, in arbitrary units).
    Specifically, curves m1 and m2 represent the relationship between the angle of rotation of the joint and the torque created by the force of attraction of the magnets 7a and 30 7b, respectively, and the line S represents the relationship between the angle of rotation of the joint and the torque created by the deformation of the narrowings 5 of the plates
    3.
    It should be noted that the narrowings 5 behave according to Hooke's law, that is, the relationship between the reaction force to the elastic deformation of the


    5 narrowings and the degree of deformation thereof is directly proportional.
    In contrast, the magnetic force of attraction between magnets 7a and magnets 7b is
    5 inversely proportional to a power of the distance that separates them. A majorseparation between magnets 7a and magnets 7b implies a lower force ofattraction, and less separation implies a greater force of attraction.
    From the graph, it can be seen that, sizing, configuring and
    10 by positioning the magnets 7a, 7b and the plates 3 in a suitable manner, it is possible to counteract the effect of the resulting torque caused by the deformation of the narrowings 5 by the resulting torque created by the magnets 7a, 7b around the X axis More specifically, it is possible to obtain a rotation interval R of the first part 1 around its rotation angle position 0 (shown in
    15 Figure 1) in which the sum of the pairs described above is essentially zero (see curve T). In other words, it is possible to obtain an interval R of rotation of the joint in which it behaves like a joint that has virtually no torque or friction.
    20 It is possible to select the type and size of magnets 7a, 7b, the initial separation distance d between the magnets 7a and the magnets 7b, the separation distance between the magnets along the longitudinal axis of the parts 1 and 2, and the type of plates 3 to obtain the most suitable R interval for each situation.
    25 By way of example, in a joint that behaves according to the graph depicted in Figure 2, the previously described selection has been carried out so that, within an approximate R rotation interval of 4 degrees (± 2 degrees) around the position of balance or rotation 0 degrees of the joint, the absolute value of the resulting torque created by the narrowings 5 around the
    The X axis is essentially equivalent to the absolute value of the resulting torque created by the magnets 7a, 7b. That is, in said interval R, the torque resulting from adding the force pairs created by the narrowings 5 and by the magnets 7a, 7b is essentially equal to zero, so that the total torque variation along said interval is essentially null (T curve) (the sum of the torque variation
    35 created by narrowings 5 and magnets 7a, 7b).


    Here, absolute force torque values will be understood to be essentially equivalent values that differ from each other an amount considered negligible by one skilled in the art, for example, a maximum amount of
    5 ± 0.005 N · mm within the R range.
    Therefore, an articulation that behaves according to the graph represented in Figure 2 implies that said articulation can rotate without producing any appreciable torque in an approximate R interval of -2 to 2 degrees around its point of
    10 rest or balance of rotation 0 degrees, that is, the first part 1 can rotate from -2 to 2 degrees around the X axis with virtually no friction, no torque variation and no torque.
    As mentioned above, the articulation of the present invention
    15 allows controlling the characteristics of the R interval. It is possible to modify the amplitude and the characteristics of the R interval by selecting the type of magnets 7a, 7b and plates 3 and their position in the joint, so that the joint can have a different R interval . For example, to increase the torque produced by the magnets, it is possible to decrease the distance d, increase the separation distance between
    20 magnets along the longitudinal axis of parts 1 and 2 or increase the size or intensity of the magnetic field of the magnets. It is also possible to increase the torque produced by the narrowings 5 by selecting a more rigid material or increasing the size of its cross section.
    25 These variations allow the torque curves of the magnets 7a, 7b and the narrowings 5 to be modified, so that the resulting curve T will be different and will define a different R interval.
    The embodiment of the invention described herein has proved to be the most advantageous known to date.
    First, the arrangement of the magnets 7a, 7b symmetrically on each side of the transverse intermediate axis of the first and second parts 1, 2 allows to obtain a steady state when the joint has not rotated (Figure 1), since, in that position, magnets 7a and 7b exert the same torque around the X axis and


    cancel each other out.
    The magnets 7a, 7b can be arranged in a different position inside each corresponding hole 6 to modify the value of d.
    5On the other hand, the fact of using two plates 3 with a clock-shaped contour ofsand makes it easy to manufacture the joint and easily change theseplates 3 if it is desired to use narrowings 5 with a different stiffness, and alsoallows to reduce to a maximum the total cross section of the narrowings 5. The
    10 plates 3 can be attached to parts 1 and 2 by removable fixing means, for example, screws.
    Although, as mentioned above, the described embodiment is the most advantageous known to date, the present invention may include
    15 different embodiments. For example, it would be possible to use only two magnets facing each other, for example, only magnets 7a. In this case, a stabilized equilibrium position would not be obtained as in Figure 1.
    As for the elastically deformable area of the joint, it also
    20 may have different configurations to those of the narrowings 5 of the two plates 3 of the described embodiment. For example, the joint could comprise a single prismatic body with the same contour as that of the plates 3 which extends along the X axis between the two long side faces of the first and second parts 1, 2 and comprising a only longitudinal narrowing.
    Likewise, although the elastically deformable zone of the embodiment (the narrowings 5) is deformed by flexion, it could also deform otherwise, for example, by torsion.
    The narrowing or narrowing 5 shown in the preferred embodiment could also have a different configuration, for example, the cavities 4 could have a triangular, rather than a semicircular shape.
    The joint could comprise a single body or piece, the first and second parts 1, 2 and the deformable zone being part of the same body or piece.


    elastically, as previously described, it could have a different configuration than the two plates 3. The joint could also be an integral part of an article or functional element, such as, for example, a hinge.
    As for the magnetic elements used in the present invention, although it isit is preferable to use magnets arranged in mutual attraction, it would also be possible to usea magnet and another element that can interact with the magnetic field of the magnet, byfor example, a metallic element, such as a ferromagnetic element (for example,an alloy of iron, steel, etc.).
    10 Parts 1 and 2 of the joint can be fixed or mobile depending on the desired use. For example, part 1 can be fixed and part 2 can be mobile, or part 1 can be mobile and part 2 can be fixed. It is also possible that both parts 1 and 2 are mobile.
    Thanks to its characteristics, the articulation of the present invention can be used in applications that require rotating movements with great precision and with zero friction and pairs, for example, in precision scales and in measuring devices of different types. Analysis.
    Next, an analysis of the operation of the joint of the present invention will be carried out, also referring to Figures 3 and 4.
    The total torque T (θ) created in the joint is given by the following expression:
        = - + (1)
    30 Where MFm1 is the pair created by the force of attraction of the magnets on the left; Mθ is the pair created by the elastically deformable zone and MFm2 is the pair created by the attractive force of the magnets on the right (Figure 3).
    35 The torque exerted by the deformable zone is proportional to the angle of rotation,


    and can be expressed as follows:
    = (2)
    5 Although the forces created by the magnets depend on the angular position of the joint, they are in the opposite direction, and are expressed as follows:
    = iD y = - 2D (3 and 4)
    10 This equation can be derived from Figure 3.
    In order for the system equation to depend on a single variable, the angle θ, the separation distance d1 between the magnets 7a and d2 between the magnets 7b and, therefore, the force equation of the magnets, must be expressed in terms of is
    15 variable, so that the separation can be expressed as:
    di = do − Dsin and d2 = do + Dsin (5 and 6)
    Where d0 is the initial value of the distance between magnets with which the
    20 rigidity necessary to make the system auto-compensate for the variation of pairs with the angle of rotation of the joint, as described below.
    The force created by the magnet system is inversely proportional to a power of the separation distance (d) between the two magnets. The precise exponent
    25 depends on the geometry of the magnet. However, with a disk-shaped magnet with a diameter much larger than the separation distance between the two magnets, the exponent is close to 1. Therefore, it is possible to express the force as:
    (7)
    Fmax and dm are constants that parameterize the dependence of force with respect to distance.
    35 Fmax is the maximum force made by the magnets (for a separation distance


    equal to zero) and dm is the separation distance with which the force has decreased to half the maximum. The expression is only valid for positive separation distances. In this case, Fm is positive according to the sign convention shown in Figure 3.
    5An example of Fmax and dm values are 14.2 N and 0.9 mm, respectively, which arecorrespond to disc-shaped magnets with a diameter of 8 mm, a3 mm height and an N45 magnetization (manufactured by the Supermagnete company).
    10 Each pair of magnets has an opposite behavior, therefore, the system has two different Fm forces (Fm1 and Fm2), which only have the same value in the 0 degree or zero nominal position of the joint (see figure 3 ). Combining the values described with an example of a deformable zone comprising two plates 3 of aluminum foil with a thickness of 0.5 mm, with a narrowing 5 with a
    15 width of 0.3 mm and with semicircular cavities 4 with a diameter of 5 mm, a graph is obtained as shown in Figure 4.
    In this graph (the values of the x-axis are degrees and those of the y-axis are N · mm) it can be seen that an R interval of rotation or stability region of the
    20 articulation between approximately -1 degrees and +1 degrees around the equilibrium position where the torque resulting from the interaction of the magnets and the deformation of the elastically deformable zone is practically equal to zero (of the order of ± 0.003 N · mm ). 25 Description of the behavior of magnets as a spring
    To describe in detail the effect of stabilization of the joint obtained by the magnets, it is worth expressing the magnetic force of the magnets in terms of an elastic constant. This can be done in a
    30 small region using Taylor's expansion of the magnetic force as follows:
    = + d − do (8)
    ��⁄� �i � ��⁄� �i
    35 This equation can be represented more compactly as:


    (9)
    where
    km has elastic constant units and, unlike elastic systems, it adopts negative values. Its adjustment is possible by properly selecting the point d0 between and zero. Torque Variation Compensation
    By combining the expressions (1), (3), (4), (5), (6) and (9), the final pair can be expressed as follows:
    = −2 D2�in - (12)
    The expression has only two terms. km must have negative values for the system to work, as will be demonstrated later.
    The principle that makes the joint torque self-compensate is that, from a stable position (the equilibrium or nominal position 0 of Figures 1 and 3) any rotation in the R interval of rotation of the joint produces a variation of
    25 auto-compensated torque whose value is zero which makes it possible to achieve a new stable position at any position within the R interval. The torque variation consists simply of the derivative of equation (12):
    (13)
    30 This derived equation is zero when the torque variation is negligible, therefore


    and, since cosθ = 0 with values of θ around zero, you get:
    (14)
    This equation means that the stiffness of the magnets must be equal to the stiffness of the deformable zone. The negative sign simply shows that km could have negative values. Constant 2 simply shows that two groups of magnets are included, if the system were configured with a group of magnets, this constant would not appear. As is evident, the distance D of the magnets to the center of the joint has a role in stiffness, since the force of the magnets multiplied by these distances is the torque exerted by the groups of magnets, which means that it would be possible adjust the interval R by modifying d0 and D.
    The distance between the magnets 7a and between the magnets 7b can be adjusted by adjusting the position of the magnet attached to the parts 1, 2, that is, d0. The adjustment of d0 affects the total force created by the joint.
    It is possible to reach the same conclusion by substituting km for its explicit expression in equation (12), being able to find the separation between magnets that produces said condition (equation 13):
    (fifteen)
    There is only one solution for positive values of d0, that is:
    (16) Stabilization interval
    The approach of the magnet system to a spring is valid within a small region or interval around d0, the error of the approximation being dominated by the quadratic term of the corresponding Taylor series.
    � = �� d − do
    d2do / d +1 �


    That, after some manipulations, it can be written as:
    do d − do 2 = do ��, d
    So the error increases faster when the strength of the magnets
    It is close to its maximum and when the maximum elastic constant is constant.
    The validity range for a given threshold is:
    The first factor is the characteristic length of the magnets. The longer, the smoother the decrease in the field. The second term is the relationship between the
    15 elastic constant and the maximum value attainable by magnets. It indicates that, in order to obtain a wide stabilization range, the elastically deformable zone should be weak compared to the magnets. Finally, the third term simply consists in the relationship between the force tolerance and the force contribution of the elastically deformable zone.
    In summary, it is necessary to use powerful magnets and use the weak part of their magnetic field to obtain a wide stabilization interval R.
