Problems solved by technology

The original organic wheel-to-axle box bearing disassembly tooling cannot be combined into a set of tooling. When installing the bearings, use the shrink-fit process or use a special bearing installation machine for assembly. The cost of tooling for axle box bearings is relatively high, and it takes up the work space. The tooling for dismantling the axle box bearings of locomotives is not user-friendly enough, which increases the labor intensity of workers

Embodiment approach

[0021] When bearing is installed, guide sleeve is fixed on the locomotive axle 16 with screw 9, and guide sleeve 10 is done centering operation with locomotive axle 16, then tightens screw 9 again. Then the lead screw 8 is screwed onto the internal thread of the guide sleeve 10 and the axlebox bearing 15 of the locomotive is horizontally placed on the guide sleeve 10, and then the pressure sleeve 11 is put on the guide screw 8 and attached to the bearing end face; The acting hollow oil cylinder 14 is set on the lead screw 8, adjust the double-acting hollow oil cylinder 14 so that it fits on the bottom end of the pressure sleeve 11, then set the gasket 7 on the lead screw 8 and tighten it with the lock nut 12, and finally start the double-acting The hollow oil cylinder 14 carries out the bearing pressing operation.

[0022] When dismounting the bearing, the guide sleeve 10 is fixed on the locomotive axle 16 with the screw 9, the guide sleeve 10 and the locomotive axle 16 are ce...

Abstract

The invention relates to the technical field of mechanical transmission systems, in particular to a locomotive wheelset axle box bearing dismounting tool. The locomotive wheelset axle box bearing dismounting tool comprises a front clamp plate, a support rod, a back clamp plate, a gasket, a guiding screw rod, a screw, a guiding sleeve, a press sleeve, a locking nut and a dual-action hollow oil cylinder, wherein the front clamp plate is connected with the back clamp plate through the parallel support rod to form a stereo space, the guiding screw rod is installed on the back clamp plate and extends into the space, the dual-action hollow oil cylinder and the gasket are sequentially installed on the guiding screw rod, the guiding sleeve is screwed at the head end of the guiding screw rod, the locking nut is arranged at the tail end of the guiding screw rod, the press sleeve is sleeved on the outer side of the guiding sleeve, and the screw is additionally arranged in the guiding sleeve. Installation and dismounting of a bearing are finished by using a set of tools, the tool manufacture cost is saved, the labor intensity of workers is reduced, and meanwhile damage-free dismounting of the bearing is ensured.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission systems, in particular to a tool for disassembling and assembling a wheel-to-axlebox bearing of a locomotive. Background technique [0002] The locomotive wheel axle box bearing disassembly tool is mainly used for the installation and disassembly of special axle box bearings in railway locomotive factories, locomotive depots and subways. The original organic wheel-to-axlebox bearing disassembly tooling cannot be combined into a set of tooling. When installing the bearings, use the shrink-fit process or use a special bearing installation machine for assembly. The cost of tooling for axle box bearings is relatively high, and the work site is occupied. The dismantling tooling for locomotive axle box bearings is not user-friendly enough, which increases the labor intensity of workers. Contents of the invention [0003] In order to overcome the deficiencies of the existing technology...
