Abstract

The invention belongs to the technical field of automobile hub bearings, and discloses a method, device, equipment and storage medium for determining the interference of a hub bearing unit. The method includes: determining the minimum interference amount according to the radial load, the inner diameter, the effective width and the rated radial static load; according to the equivalent outer diameter of the inner ring, the fit surface diameter, the equivalent inner diameter of the inner flange shaft, the elastic modulus, the fracture limit of the quenched inner ring and the quenched inner flange shaft and the safety factor, determine the maximum interference; The maximum interference amount and the minimum interference amount are corrected; according to the corrected minimum interference amount and the corrected maximum interference amount, the interference range of the hub bearing unit is determined. Through the above method, the reasonable interference range of the hub bearing unit can be determined, so that the produced hub bearing unit is within the reasonable interference range, and the inner ring of the hub bearing unit is avoided from loosening and cracking.

Description

technical field [0001] The invention relates to the technical field of automobile wheel hub bearings, in particular to a method, device, equipment and storage medium for determining the interference amount of a wheel hub bearing unit. Background technique [0002] Automobile wheel bearing is a key mechanical foundation in my country's advanced manufacturing field. Its function is to carry and provide precise guidance for wheel hub transmission. In the design and manufacture of the third-generation wheel hub bearing unit, the inner ring and the inner flange are connected together with an interference fit. If the interference is too small, the inner ring will rotate when the hub bearing unit is working. If the interference is too large, the inner ring will be broken. Therefore, reasonable interference design is one of the key issues in the manufacturing process of hub bearing units. In addition, different from the previous two generations of products, the third-generation wh...
