Abstract

The invention discloses a subway axle box bearing. The subway axle box bearing consists of an outer ring, an inner ring, an inner retainer ring, two columns of rollers, two retainers of an integral structure, two sealing rings and a movable inner spacer ring, wherein the outer ring is provided with two raceways, the inner ring is a single raceway, the inner spacer ring is in a barrel shape, the outer ring is installed at the outer side of the inner ring, the two raceways of the outer ring correspond to the single raceway of the inner ring, one side of the inner ring is connected with the innerretainer ring, the two raceways of the outer ring are separately provided with one retainer of the integral structure, a roller is installed in the retainer, the movable inner spacer ring is installed between the two retainers, and the middle parts of two ends of the outer ring and the inner ring are separately provided with the sealing ring. The subway axle box bearing actually solves the defects of the bearing at present and has the advantages of high speed, heavy load, reliable performance and the like and is convenient in use and long in service life.

Description

technical field [0001] The invention relates to a bearing, in particular to a subway axle box bearing. Background technique [0002] The subway axle box bearing is the movable joint connecting the wheel set and the frame of the subway vehicle, and the key component that transmits the traction force, lateral force and vertical force. Its operating state is directly related to the ride comfort and operation safety of the vehicle. [0003] The traditional design is that the cage is connected by the cage seat and the cage cover through rivets. This structure is easy to cause the rivets to loosen or even fall off under the working conditions of frequent starting and braking of the subway. After the rivets fall off, enter the The inside of the bearing will cause damage to the bearing in an instant, causing an accident. [0004] In recent years, in order to adapt to the rapid development of rail transit in the world and the acceleration of urbanization in China, the construction o...
