High-speed and high-load hub bearing unit and assembling method thereof

Abstract

The invention discloses a high-speed high-load hub bearing unit and an assembling method thereof. The high-speed high-load hub bearing unit comprises a body, wherein the body is provided with a bearing sleeve, an inner flange plate arranged at the front end of the bearing sleeve, and a fixing plate fixedly connected to the outer side wall of the rear end of the bearing sleeve; positioning holes and mounting holes are distributed in the circumference of the inner flange plate at intervals; connecting screw rods are arranged in the mounting holes; the outer side of the bearing sleeve is sleevedwith a reinforcing sleeve; the reinforcing sleeve is located between the inner flange plate and the fixing plate; the fixing plate is provided with a clamping assembly; and the clamping assembly clamps the reinforcing sleeve, so that the reinforcing sleeve clamps the outer side wall of the bearing sleeve. The method comprises the following steps of a, preparing before assembling; b, clamping; c, assembling the reinforcing sleeve; d, assembling the clamping assembly; and e, completing assembling. According to the high-speed high-load hub bearing unit and the assembling method thereof provided by the invention, the stability and the bearing capacity of the bearing sleeve are improved, and deformation and cracks of the bearing sleeve are avoided, so that the service life of the hub bearing unit is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of bearing equipment, and in particular relates to a high-speed and high-load hub bearing unit and an assembly method thereof. Background technique [0002] The main function of the hub bearing is to bear weight and provide precise guidance for the rotation of the hub. It bears both axial load and radial load, and is a very important component. Traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of the bearings are all carried out on the automobile production line. This structure makes it difficult to assemble in the automobile production plant, high in cost, and poor in reliability. Moreover, when the automobile is maintained at the maintenance point, the bearing needs to be cleaned, oiled and adjusted. The hub bearing unit is developed on the basis of standard angular contact ball bearings an...

AI Technical Summary

Problems solved by technology

[0003] Since the hub bearing unit of the automobile has to bear both axial load and radial load, it is easy to cause deformation of the bearing, which will cause the inner ring of the bearing to be stuck. In severe cases, the shell of the bearing will crack, resulting in cracks in the bearing Lubricating oil leakage causes the bearing to heat up and wear excessively, which greatly reduces the service life of the bearing
