Assembling and adjusting test bench for split type moving wheel pair hollow shaft sleeve

Abstract

The assembly and adjustment test bench for the hollow shaft sleeve of the split type dynamic wheel set belongs to the field of assembly and adjustment devices for the split hollow shaft wheel set sleeve of rail vehicles. The test bench includes a platform, two V-shaped block assemblies, two small compression Assembly and two large compression assemblies, the V-block assembly includes a V-block and two shock-absorbing anti-skid pads. The platform with two V-shaped block assemblies of the present invention can support and position the half-window of the hollow shaft, so that the rim and the half-window can be respectively pushed by two sets of screw screws opposite to each other to provide a strong enough thrust to overcome the frictional force, It can assist in the micro-displacement adjustment between the axle and the half window and the assembly process of the adjustment shim. In addition, the installation and adjustment test bench also has the advantages of simple operation, low cost and high control precision.

Description

technical field [0001] The invention belongs to the field of assembly and adjustment devices for rail vehicle split type hollow shaft wheel set sleeves, and in particular relates to an assembly and adjustment test bench for split type moving wheel pair hollow shaft sleeves. Background technique [0002] The front section and the rear section of the hollow shaft sleeve are respectively provided with bearing grooves for loading wheel set bearings. However, the moving wheel set of the 5M-M train in South Africa is a split hollow shaft sleeve power transmission form. Second, the part with the boss is the half-brush part, and the part without the boss is the half-window part, and the two can be fastened together. The hollow shaft sleeve of this type of split type dynamic wheel set cannot be hoisted, placed and assembled like a conventional wheel set. [0003] Such as Figure 1 to Figure 3 As shown, when the rim 6 is assembled with the hollow shaft sleeve, the half window 7 and ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the lack of a special assembly and adjustment test bench for the hollow shaft sleeve of the existing split-type moving wheel set, there are many difficulties in its hoisting, placement, assembly and subsequent test and adjustment processes, especially the inability to control the wheel set bearing and the half-window bearing groove The adjustment accuracy of the gap between the gaps causes the technical problem that the quality of the installation and adjustment is difficult to guarantee. The invention provides an assembly and adjustment test bench for the hollow shaft sleeve of the split type moving wheel
