Abstract

A bearing device for a track wheel comprises a wheel body (1) and a rotary shaft (2) and is characterized in that balls (3) are arranged between the wheel body (1) and the rotary shaft (2), an inner wall of the wheel body (1) is provided with an inner annular groove (11), an outer annular groove (21) is arranged at the corresponding position of the rotary shaft (2), the balls (3) can arranged on a retainer (4) in a rolling mode and can be movably arranged between the wheel body (1) and the rotary shaft (2) together with the retainer (4), the outer surfaces of the balls (3) are contacted with the surfaces of the inner annular groove (11) and the outer annular groove (21), and two ends of the rotary shaft (2) are arranged on a support (5) at the bottom of a vehicle body. The bearing device for the track wheel has the advantages that the bearing device is compact in structure, double rows of balls are arranged between the wheel body and the rotary shaft and can enable wheel to be stable in running, a dust-proof cover and a rubber sealing ring can have double sealing effects, and accordingly the service life of the wheel is prolonged.

Description

technical field [0001] The invention relates to the technical field of making rail wheels, in particular to a bearing device for rail wheels. Background technique [0002] Existing a kind of patent No. is CN201120039760.5 and the Chinese utility model patent of title " track small wheel " discloses a kind of track small wheel, comprises two parallel tracks and car body, and axle is arranged in the car body, and the two axles The ends protrude from the car body and are respectively equipped with rollers through double bearings. The rollers are respectively placed on two parallel rails and are slidably matched with the two parallel rails. The outer wall of the rollers is provided with annular steps. The side wall is a slope surface; a motor is fixedly installed at the end of the car body, and the motor is connected with the axle drive. However, it adopts a double-row rolling bearing arranged between the wheel and the axle, and its structure is not compact enough, and foreign ...
