    The invention relates to methods for assembling axles and bearings, in particular in supports and with pretension, more particularly for the axes of encoders.
    The method of installing axle bearings, in particular, encoders, differs in that it consists in applying glue to the axle at the level of the place where the first bearing is installed, introducing the specified axle into the inner ring of the first bearing until it stops at the bottom of the housing of the first bearing, in applying glue to the axle at the level of the place where the second bearing is installed, inserting it into the mounting socket, installing an intermediate pre-tension spring on the axis, sliding the second bearing onto the axle. bringing the second bearing into its working position using a press interacting with the mounting socket, applying glue, on the one hand, to the bottom of the encoder support at the level of the cavity for one of the bearings, and on the other hand, the other bearing on its outer ring, and finally , installing the axle with its bearings in the specified support.
    The device for implementing the described method is characterized in that it consists of an installation for applying glue to the axle, bearings and support of the encoder, a first seat for mounting the first bearing, and a set of seats and presses for mounting with pretensioning of the second bearing.

    The encoder is characterized in that it is equipped with an axle which is pre-tensioned in its support on bearings.
    Figure 1 is a cross-sectional view of a coding device obtained using the ps method of the invention; Fig. 2 is a plan view of a device for using the method according to the invention; Fig. 3 is a section on an enlarged scale of the nest-press complex of the device according to Fig. 2.
    In accordance with the invention, the method of mounting the bearings 1 of the axles 2, in particular of the encoders, consists in applying glue to the axle 2 at the level of the mounting place of the first bearing 1, introducing the axle 2 into the inner ring of the first bearing 1 until it stops against the bottom of the seat 3 of the conductor of the first bearing 1.
    Glue is applied to the axle 2 at the level of the mounting place of the second bearing 1, then the axis is placed in the mounting slot 4 for mounting the latter. Then a preload spring 5 is installed on the axle 2 and the second bearing 1 is pushed onto the axle 2. This second bearing 1 is brought into its working position by means of a press 6 interacting with the seat 4. At the bottom of the support 7 of the encoder 8 (Fig. 1) glue at the level of the cavity for one of the bearings 1, and the other bearing 1 is glued with its outer ring, and finally, the axis 2 with its bearings 1 is installed in the specified support 7.
    This embodiment makes it possible to mount and label the commercial bearing on the outer ring directly on the simple axes, with the exception of the end portions, which are made depending on the use of the encoder. This mounting of the bearings is carried out with pre-tensioning of the intermediate spring, which rests on the outer bearing cages 1, and the pre-tension is carried out using a press 6, interacting with the seat 4, after the installation of the second bearing, and the polymerisation of the glue leads to the final fixing of the relative position of the two bearings.
    The pretension acting on the spring 5 can be preliminarily adjusted by acting on it, that is, by the appropriate choice of the section of the wire forming it or the number of turns, or else by its destruction stroke.
    It is enough that the press 6 develops a force sufficient to compress the spring 5 until its application surface, acting on the corresponding bearing 1 during the installation of the latter, comes to the stop in the seat 4.
    The assembly and sticker of the set of axle 2 of bearing 1 in support 7 of the encoder 8 is carried out manually up to the stop of the corresponding bearing 1 against the bottom of the support 7.
    The device for using the described method consists of a station 9 for applying glue to the axes 2, bearings 1 and support 7 of the encoder 8, the first seat 3 for mounting the first bearing 1 and a set of seat 4 and presses 6 for mounting with pre-tensioning of the second bearing 1.
    Station 9 for gluing the axis 2, bearings 1 and support 7 of the encoder 8 consists mainly of a drum 10 for mounting and driving the axis 2 or an encoder 8 with a mandrel, and of a pipette 11 for supplying glue to the gluing points, connected to the glue reservoir , moreover, the command to turn the drum simultaneously sends the command to supply the glue and can be executed with the foot.
    The first seat 3 consists of a cup with a support collar 12 for the first bearing 1 and provides placement of the axis 2, and the distance between the support surface of the collar 12 and the bottom of the cup is equal to the distance between the support surface of the bearing 1 and the opposite end of the axis 2 (Fig. 2).
    Thus, after mounting the first bearing 1 on axis 2, it is enough to insert this axis 2 with its end opposite to bearing 1 into slot 3 and bring the end of axis 2 to the stop with the bottom of the seat 3, and bearing 1 to the stop with the collar 12 of the indicated seat
    3..
    Each nest 4, interacting with the press 6, consists of (as shown in Fig. 3) a glass, which can be installed coaxially with the power cylinder of the corresponding press 6 by replaceable insertion into the hole 13 of the jig 14 of the press 6, and the glass has a closed bottom 15 to support the end of the axle 2 and guide the bearings 1 along their outer rings.
    Each press 6 consists of a power cylinder, the head 16 of which is equipped with a hollow cylindrical section 17, designed to slide onto the corresponding mounting end of the axis 2 of the bearing 1 and support on the upper bearing, and a cylindrical section of larger diameter 18, offset with respect to the hollow section 17 and intended for bearing on the upper supporting surface of the corresponding socket 4, the length of the offset between the surfaces of the sections 17 and 18 corresponds to the length of insertion of the section 17 into the socket 4, which is necessary to pre-tension the spring 5.. '
    Thus, after adjusting this distance, the pretension of the spring 5 is obtained automatically, and the relative position of the bearings 1 is ensured with absolutely perfect repetition when moving from one axis 2 to another during the entire production time of a series of coding devices of the same type. In the event of a change in manufacture, it is sufficient to match the dimensions of the socket and sections 17 and 18 of the head 16 of each press 6 with the dimensions of the new series of axes and. bearings they carry.
    The encoder 8 is equipped with an axle 2 pre-tensioned in its support by means of bearings 1 loaded with a spring 5 located between the outer rings (fig. 1).
    The encoding device 8 obtained using the method according to the invention by means of the described device can be ideally adapted for its specific application; moreover, the mounting of its axes in the support can be ideally adjusted to a predetermined tension.
