Hub bearing with spline structure

Abstract

The invention discloses a hub bearing with a spline structure. The hub bearing with the spline structure comprises a rotary connector, a flange inner ring, a flange outer ring and a connecting inner ring, a first rolling groove is formed between the flange inner ring and the flange outer ring, a second rolling groove is formed between the connecting inner ring and the flange outer ring, steel balls are arranged in the first rolling groove and the second rolling groove, a clamping groove is formed in the flange inner ring, the connecting inner ring is arranged in a split mode to form a first ring body and a second ring body, a plurality of guide grooves and guide blocks are arranged between the first ring body and the second ring body, the guide grooves and the guide blocks are formed in an inserted fit mode, the first ring body is clamped in the clamping groove, a first sliding way and a second sliding way are arranged at the positions, corresponding to the steel balls, of the first ring body and the second ring body respectively, the second ring body extends towards the flange outer ring to form a shielding table, and the second ring body extends towards the rotary connector to form a shielding table. The structure is reasonable, a good sealing effect is achieved, disassembly for oil supplementing is convenient, and the using effect of the whole structure is improved.

Description

Technical field [0001] The present invention relates to the field of hub bearings. Background technique [0002] The wheel bearing of the drive wheel is typically used in pairs, and the outer spline is connected to the vehicle drive element, that is, the ball cage is connected to the vehicle power transmission. The traditional hub bearing is in use, due to the continuous vibration of the working environment, and the working environment is poor, the external impurities can easily affect the overall structure, and it is easy to enter the inside of the bearing, which seriously affects the overall structure, and the overall bearing is in the process of use, There is a lot of lubricating oil to maintain the smoothness of the overall work. At present, the hub bearing is difficult, and the overall disassembly replacement is required, the maintenance cost is high, reducing the overall structure. Inventive content [0003] In response to the deficiencies of the prior art, the present inv...

AI Technical Summary

Problems solved by technology

When the traditional hub bearing is in use, due to the continuous vibration of the working environment and the harsh working environment, external impurities are easy to affect the overall structure and easily enter the interior of the bearing, which seriously affects the use effect of the overall structure. At the same time, during the use of the overall bearing, A large amount of lubricating grease is required to maintain the smoothness of the overall work. At present, it is difficult to replenish oil for the hub bearing, and it needs to be disassembled and replaced as a whole. The maintenance cost is high and the use effect of the overall structure is reduced.
