The invention of the RCTs one-piece forging of metal compounds nodes, for example, for the removal of the axes of the sleeves or rings.

There are various designs of equipment (rods) for repressive immovable joints of metal nodes.

Known, for example, the installation for hot repressive parts-axle railway wheelsets (see kN. A. A. Amelina the Device and repair of wagon axle box roller bearings), Transport, 1975, page 218. ..222), comprising a housing, engagement with a drive of its movement and the induction heater.

Using this setup with the axis of the wheelset removed labyrinth ring and the inner ring of the bearing. However, before dismantling it is necessary to carry out the draining remove the ring, then perform its heating using an induction heater, and after dismantling to produce the cooling ring and the axis, leading to a high cost of time, reduced productivity and, consequently, high costs of maintenance, housing (rigidly connected to the piston of the hydraulic cylinder) relative to the shaft removable connection with a fixed swinging paws capture, previously entered into engagement with removable sleeve.

This set the stop of this design for disassembly of bearing assemblies railway wheelset is necessary for each of the repaired wheel pair, having individual sizes axis length and diameter, wheel diameter, and equal sizes of bearings and axle equipment, manufacturing individual installation - puller. And this, in turn, of course, leads to higher costs on time and to high costs of maintenance.

The closest solution to the claimed technical essence and the achieved result from its use is the design of the known installation for cold repressive site train wheel pair on and. C. the USSR N 565803, B 23 P 19/02, 1977, comprising a housing with a grip and the drive movement of the grip along the axis of the movable unit, performed in the form of a hydraulic cylinder.

This setup, though, and can be dismantled node train wheel pair, but its design features create inconvenience for staff and do not provide the high performance of the work.

The challenge which seeks the invention is to increase the efficiency of repair work when removing the node from the failed train wheel pair.

This task is solved with a technical result from ispolzovaniem work and reduce their costs regardless of the size and type of parts and components repaired a pair of wheels.

This result is achieved in that in the known installation for cold repressive site train wheel pair, comprising a housing with a grip and the drive movement of the grip along the axis of the movable unit, performed in the form of a hydraulic cylinder is further provided with a carriage and rigidly connected by a bracket having a cylindrical and a profile part, the body is made in the form of a lifting table with actuators lifting and longitudinal feed, the latter of which is equipped with a rod fixedly connected to the bracket, and a carriage mounted on the lifting table can be moved along the axis of the cylinder, which is placed on the carriage and provided with a focus-limiter in the form of a Cup with a flange at one end, fixed to the other end of the housing of the hydraulic cylinder coaxially of the latter, while this grip is made with swinging legs, each of which is pivotally mounted on the cylindrical portion of the bracket and provided with a drive of its turn, pivotally connected by one end with the relevant part of the bracket, and the other with swinging leg, the axis of rotation of the legs are parallel to the axis of the cylinder, and the end stop is mounted for interaction with its flange which may be made in the cross-section is T-shaped.

Introduction to the design of the installation of additional mechanisms, as well as special execution and careful placement of existing and additional mechanisms can significantly reduce costs and improve the performance of repair work, especially when removing the labyrinth ring and the inner ring of the bearing Assembly with the axle equipment railway wheelsets.

The invention is illustrated by drawings, in which:

- Fig. 1 shows a General view in the context of the proposed facility showing the operating positions of the mechanisms installed at different points in the business cycle;

- Fig. 2 shows a cross-section of the proposed facility along a-a to display the design of the working bodies of capture at different points in their work.

We offer installation for cold repressive site railway wheelset includes a housing 1, a grip 2 with swinging legs 3 and 4, hinged to the body 1, and the drive motion capture 2 along the axis of the movable node 5, is made in the form of a hydraulic cylinder 6. The housing 1 is made in the form of an elevating table with actuators lift 7 and the longitudinal feed 8 and provided with a carriage 9 that is installed on the housing 1 can be moved along the attachment part, and rigidly connected to the carriage 9, and the shaft 13 of the drive line feed 8 of the housing 1. The cylinder 6 is mounted on the carriage 9 and is provided with a focus - limiter 14 made in the form of a Cup with a flange 15 at one end and the other face fixedly mounted on the housing 16 of the hydraulic cylinder 6 is coaxially him. While the end stop 14 is interacting with its flange to the cylindrical portion 11 of the bracket 10 and the swinging legs 3 and 4 of the grip 2, and the swinging of the legs 3 and 4 capture 2 hinged to the cylindrical part 11 of the bracket 10 in such a way that their axes of rotation 17 and 18 parallel to the axis of the cylinder 6, each swinging paw 3 or 4 of the grip 2 is provided with drive its rotation 19 or 20, pivoted at one end on the core portion 12 of the bracket 10 and the other end to the swinging leg 3 or 4 of the grip 2.

To ensure accurate installation of the housing 1 to its original position on the bracket 10 is installed sensors lifting 21, which through a system control unit (not shown) provide the necessary level of lifting of the housing 1, and timely disconnection of the lifting drive 7.

For continuous monitoring of the location of the housing 16 along the move 22.

Operation of the proposed facility for cold repressive site train wheel pair is as follows.

When submitting repaired railway wheelsets 23 bearing 24 having outer labyrinth ring 25 and the inner ring 26, and panel Jack 27 (with the cover removed pan) in the position of repressive installation for cold repressive is in the initial position with a lowered (see Fig. 1) body (lifting table 1, with the right reserved by the hydraulic cylinder 6 on the carriage 9 and turned, swinging the legs 3 and 4 capture 2 (see Fig. 2) in position B.

To signal the beginning of the cycle, the carriage 9 with a drive line feed 8 rod 13 is moved to the left to the end of the axis 29 of the pair of wheels 23 to alarm horizontal movement 22. At the end of the rod 30 of the hydraulic cylinder 6 abuts against the end of the axis 29 of the pair of wheels 23.

After this case (lift table) 1 with a drive lift 7 lift up to trip the sensors lift 21. Then swing the legs 3 and 4 capture 2 with drives of rotation 19 and 20 zagladivaut, transferring them from their original position. This swinging of the legs 3 and 4 go behind the thrust collar 31 of the bracket 10 and C is luchot cylinder 6, the rod 30 which apart at the end of the axis 29 of the pair of wheels 23, and moves the housing 16 of the hydraulic cylinder 6 (to the right in Fig. 1). This movement through the end stop 14 is transmitted to the grip 2, which, in turn, swinging his legs 3 and 4 captures and pulls labyrinth ring 25 and the inner ring 26 of the bearing 24 with the axis 29 of the pair of wheels 23 together with the axle box housing 27. With the inner ring 26 of the bearing 24 crawls on the rod 30 (of smaller diameter than the diameter of seat axis 29 of the pair of wheels 23) of the cylinder 6.

At the end of the stroke of the hydraulic cylinder 6 swinging legs 3 and 4 capture 2 with drives of rotation 19 and 20 back to its original position (see Fig. 2).

After this case (lift table) 1 is installed in a position convenient for the removal of dismantled parts, and removed from installation shot of the ring and the axle box housing.

Installation ready for a new cycle of the dismantling of the next node.

The use of the invention allows to:

1. To ensure repressive labyrinth rings and the inner rings of the bearings failed railway wheelset, regardless of the actual size and type of parts wheelset (axis and to the decision performance of repairs by eliminating the need to perform various additional preparatory operations.

3. To improve the working conditions of the staff, to ensure the possibility of automating the process of repressive.
