    , one
    relates to machine building Invention of swarming, namely, devices for converting rotary motion into reciprocating linear motion, and can be used, in particular, to control axial pumps.
    The aim of the invention is to increase reliability and ease installation.
    This goal is achieved by rational arrangement of bearings, which allows us to better withstand alternating bending moments acting during operation of the device, which allows to increase the life of the bearings and simplifies their replacement.


    The drawing shows a motion conversion device, a slit.
    The motion converting device comprises a fixed crankcase 1, inside of which is installed a swinging disk 2, the longitudinal axis 3 of which passes through the center of swing 0. In the case of using the device for controlling axial pumps, cylinders 4 are evenly spaced around axis 3 on one side of center O; One of them is shown in section in the plane of the figure to show the piston 5 connected to the disk 2 by means of a connecting rod 6 with articulated ends. On the other hand from the center O on the crankcase 1 is mounted a drive containing gear 7, interacting with a gear wheel, centered along axis 3 and mounted with bearings 9 on the crankcase 1. Pin 10 is pivotally connected to the wheel 8 with one end of a hydraulic cylinder 11 and the other is rigidly connected to the disk 2, the longitudinal axis 12 of the trunnion -10 passes through the center of the swing 0. The cardan swivel connection of the disk 2 to the crankcase 1 is formed by the cross-bar 13 mounted to the perpendicular axis on the crankcase 1 The axis is mounted inside the central cavity of the cross member 13, bounded by a cylindrical wall 14, the axis of which passes through the center O and perpendicular to one side of the axis of rotation of the cross member, and on the other - axis 12 studs 10.
    The hinge axis is formed by a thrust 15, the ends 16 and 17 of which are supported respectively on two parts 18 and 19 of the disk 2, forming a casing that covers the central part of the wall 14 of the cross member 13. The device contains four bearings 20, the outer rings 21 of which have an outer diameter equal to the inner diameter of the cylindrical wall 14, and form a sliding joint with the latter. The spacer rings 22 have a height so large that the whole set of bearings
    The collar is located in the cavity of the wall 14, at the ends of which the straps 23 are mounted for fastening the set. The device uses tapered bearings, the effective load centers of which are located symmetrically
    with respect to the center of swing -O. The bearings are mounted before mounting the disc on either side of the cross member 13, therefore the sealing ring mounted in the center of the hinge joint can be formed by the support ring lug 24 of the cross member 13.
    The inner rings 25 of the bearings are slid over the landing
    a cylindrical sleeve 26, which, without a gap, is mounted on the swivel link 15 and occupies the entire space between two parts 18 and 19 of the casing of the disk 2.
    The number and dimensions of bearings are chosen in such a way that they are evenly distributed along sleeve 26, the entire length of which covers a set of inner rings 25. In the intervals between the inner rings 25. spacer rings 27 are installed, which preferably are slid over a slide along the sleeve, mounted on sleeve 26 in such a way that the set of internal rings 25 and spacer rings 27 covers the entire length of the sleeve.
    Due to this arrangement, the prestressing force applied to the rifle 15 is distributed between the sleeve 26 and the assembly kit of the inner rings 25 together with the spacer rings 27. The assembly has a height slightly greater than the length of the sleeve 26, so that the force of the preliminary tension is perceived primarily spikes
    Proceeding from the use of conical podishpniki, the force of compression
    inner rings 25 determines the elastic radial deformation of the bearings, the inner rings 25 are supported
    on the cylindrical wall of the sleeve 26, and the outer rings 21 on the cylindrical wall 14 of the central axis of the cross member 1 3.
    Based on the geometric measurements of the bearings, cavities of the wall 14 and the sleeve 26, it is possible to calculate the radial deformations of the bearings and the cross member in the presence of axial force and choose the thickness of the gasket rings 27 so that the load is evenly distributed between the bearings, all the rings are pressed to the cross member 13 and the sleeve 26 Thus, it is possible to eliminate all radial gaps between the rings of the sleeve 26 and the cavity of the wall 14, which is practically important in order to ensure alternating bending moments acting on the hinge joint. .
    By calculating the radial deformations and the compression force of the bearing assembly in this way, the length of the sleeve 26 can be made equal to the overall height of the internal 25 assembly kit and gasket 27 rings, reduced compression, and (thus, eliminating gaps, since the additional axial force is perceived by the sleeve 26. T ha 15, having thus received a prestressing, it is better able to withstand the bending of the bendings
    The thrust part 15, located between the parts 18 and 19 of the casing, is completely closed without a gap by the sleeve 26 and the outer wall of the latter is completely closed by the bearing assembly kit and

    . spacer rings 27, which transmit radial load to it. Thus, the risk of buckling and bushings is eliminated.
    The hinge assembly is assembled as follows.
    First, a cross-member 13 is installed in the crankcase 1, into which, one after the other, in the cavity of the wall 14 on both sides of the annular protrusion 24 are placed the bearings 20, rings 21 and 27, the assembly is fixed by straps 23. Then put the sleeve 26 on and cover the assembly with a casing formed by parts 18 and 19 of the disk 2. It remains only to put on the disk 2 and the sleeve 26 tons of gu 15, one supporting end 16 of which is hinged and mounted in the bore formed in the disk part 18, in relation to which it is blocked by a key 28. The other end gi is made in the form of a nut 17, with which the collection is compressed The disk 2 is mounted on its hinge joint and secured thereto. 25 heads of rods 6.

    The device works as follows.
    Gear 7 drives the wheel 8 and therefore the trunnion 10 to rotate. Axis 12 describes a cone with a top in the center of the swing O, relative to which the disk -2 makes a swinging motion.
    The angle of inclination A of axis 12 to axis 3 is controlled by radial movement of the axle 10 by the hydraulic cylinder 11, which provides a change in the stroke of the pistons 5 and, accordingly, the amount of pressure.
