Method for mounting bushing

Abstract

The invention provides a method for mounting a bushing. The method comprises the following steps of: aligning the guiding end of the bushing with a mounting hole passing through a mounting plate; inserting a mounting shaft into the bushing and the mounting hole; and screwing a nut in the mounting shaft, so that the bushing is extruded into the mounting hole in the screwing process. By the method, the bushing can be mounted under the adverse conditions of narrow space, incapability of changing positions at random and the like, so the method is easy and convenient to operate and high in practicality; and the positional deviation of the mounted bushing in the mounting hole can be avoided, and a mounting effect is good.

Description

technical field [0001] The invention relates to a bush installation method, which belongs to the technical field of bush assembly. Background technique [0002] The braking device is an important device on all rolling stock, and it is used to provide braking force when the train is running to achieve the purpose of decelerating or stopping the train and ensure the safe operation of the train. In order to effectively reduce the maintenance cost and workload of the rolling stock user, the brake round pin and the bushing are usually used in pairs at the movable joint of the brake device, wherein the bushing needs to be installed in the mounting hole on the mounting plate , The brake round pin is installed in the bushing. [0003] Existing mounting panels can be constructed in a single layer; or, as Figure 1A with Figure 1B As shown, the mounting board 10 can also be a double-layer structure, and each layer of the mounting board is provided with three continuous mounting hol...

AI Technical Summary

Problems solved by technology

[0004] There are at least the following problems in the prior art: it is quite laborious to install the bushing by means of hammering, so the operation is inconvenient; and the installed bushing is prone to position deviation in the mounting hole, and the installation effect is poor; The installation method of smashing the bushing 20 into the mounting hole 11 by hammering etc. requires enough space around the mounting plate 10 for the installer to swing the hammering tool so as to generate enough impact force to smash the bushing 20 into the mounting hole 11

But, after some existing locomotives are transformed through technology, the space around the mounting plate 10 becomes very narrow, and the mounting plate 10 is also often welded with other parts such as the frame to become an integral body, thus it is difficult to arbitrarily change the position, so it can no longer be used. Bushing installation by hammering etc. as above
