Description

A kind of subway axle box bearing
Technical field
The present invention relates to a kind of bearing, more particularly to a kind of subway axle box bearing.
Background technology
Subway axle box bearing is the turning joint of railcar fifth wheel pair and framework, and transmit tractive force, cross force and The critical component of vertical force, its operating condition be directly connected to the ride quality of vehicle with it is safe for operation.
Traditional retainer that is designed as is connected by holding stand and retainer lid by rivet, and this structure exists Under the conditions of subway frequent starting and the applying working condition of brake, it is easy to even come off so that rivet produces to loosen, after rivet comes off Bearing is caused to damage in moment into Bearing inner, and then triggers accident.
In recent years, it is the fast development of adaptation world's station design, the quickening of Chinese Urbanization's paces, city underground It is imperative to build.City underground has the characteristics that freight volume is big, speed is fast, pollution is small, energy consumption is low, runs on schedule, be safe. To meet the performance of subway bearing, it is necessary to which the design to subway bearing improves.
The content of the invention
The purpose of the present invention is that open one kind has the advantages that high speed, heavy duty, dependable performance, easy to use, long lifespan Subway axle box bearing.
A kind of subway axle box bearing, by an outer ring, an inner ring, an inner shield ring, two row rollers, two overall structures Retainer, two sealing rings and a movable cone spacer composition, the outer ring are provided with double raceways, and inner ring is single raceway, described interior Spacer ring is drum-shaped, and the outer ring is mounted in the outside of inner ring, corresponding in double raceways of outer ring and single raceway of inner ring, inner ring Side connects with inner shield ring, and an overall structure retainer is respectively filled at double raceways of outer ring, and roller is fitted into retainer, activity Cone spacer is installed among two retainers, and sealing ring is respectively provided with outer ring and inner ring both ends middle part.
Oiling groove is provided with the overall structure retainer.
The overall structure retainer is wedge-shaped pocket hole, and prolonging radial direction retainer external diameter direction in retainer has certain angle Degree.
The retainer oiling groove angle is 90 °.
The overall structure retainer is circular arc pocket hole.
There is movable inner shield ring between two rollers, a certain amount of axial force can be born.
Using overall structure retainer, integral cage must accomplish rolling element can self-locking, the retainer of this structure Machining accuracy is high, occupies little space, can make the quantity of roller increase, and meets the requirement of heavy duty.
Sealing ring coordinates by outside dimension and external diameter bulge quantity with outer ring, can preferably prevent extraneous dust from entering bearing Inside, keep the spatter property of bearing internal work environment.
Movable cone spacer plays axial isolation and guiding function to two row rollers, effectively controls its appearance and size to bearing assemble Play positive role.
Overall structure retainer is wedge-shaped pocket hole, and prolonging radial direction retainer external diameter direction in retainer has certain angle, pocket Hole has certain hold depth to rolling element in retainer inner radius, ensures that the rolling element for loading retainer can not be from retainer inner radius Come off, and after bearing inner race is encased in Bearing inner so that rolling element shift to the bearing centre of gyration and with retainer pocket hole Certain gap is formed, is advantageous to the flexibility of the rotation of bearing.The retainer machining accuracy of this structure is high, space-consuming It is small, compared to the length and quantity that the design of traditional retainer can increase roller, and then the rated load of bearing is improved, meet heavy duty Requirement.
The subway axle box bearing of the present invention is insufficient existing for current kind of bearings from actually solving, and has at a high speed, again The advantages that load, dependable performance, easy to use, long lifespan.
