Gauge-changeable wheel set shaft box bearing assembling device and assembling method thereof

Abstract

The invention relates to the technical field of gauge change of railway vehicles and discloses a gauge-changeable wheel set shaft box bearing assembling device and an assembling method thereof. The gauge-changeable wheel set shaft box bearing assembling device comprises a process shaft, inner sleeves, bearing guide sleeves, bearing outer sleeve components and pressing sleeve components, wherein the process shaft comprises a process shaft body and shaft shoulders arranged at two ends of the process shaft body; the inner sleeves are respectively sleeved on the process shaft body and are respectively matched with the shaft shoulders on the corresponding sides; the bearing guide sleeves are respectively connected with two ends of the process shaft body; the bearing outer sleeve components arerespectively movably sleeved on the bearing guide sleeves on the corresponding sides; the pressing sleeve components are respectively arranged at two ends of the process shaft body; the ends facing tothe bearing guide sleeves of the pressing sleeve components are arranged on the bearing guide sleeves; and the pressing sleeve components are driven to move in directions toward the shaft shoulders,so that the bearing outer sleeve components are pushed to the inner sleeves by the bearing guide sleeves and are propped against the shaft shoulders. The gauge-changeable wheel set shaft box bearing assembling device has the advantage that the pressing requirements of gauge-changeable wheel set shaft box bearings can be met.

Description

technical field [0001] The invention relates to the technical field of rail vehicle gauge change, in particular to an assembly device and an assembly method of a gauge change wheel set axle box bearing. Background technique [0002] Cross-border passenger and cargo transportation has grown rapidly this year. However, due to the different gauges of railways in various countries, it has caused serious obstacles to cross-border railway transportation. In order to solve the problem that the different gauges of railways in various countries hinder cross-border railway transportation, a variable-gauge train is proposed, that is, when the train travels to a railway in another country, the distance between the wheels on the axle is changed. , to adapt to the gauge of railways in other countries. [0003] The variable gauge wheel set is different from the traditional wheel set. The axle box bearing of the variable gauge wheel set is press-fitted on the inner sleeve instead of direct...

AI Technical Summary

Problems solved by technology

[0003] The variable gauge wheel set is different from the traditional wheel set. The axle box bearing of the variable gauge wheel set is press-fitted on the inner sleeve instead of directly on the axle. Therefore, the traditional press-fitting method and press-fitting device cannot be applied The gauge wheel set structure urgently needs a variable gauge wheel set bearing assembly device that can meet the needs of press mounting of the variable gauge wheel set axle box bearings
