Abstract

This invention discloses a manufacturing method for an integrated sealed wheel hub bearing with a toothed ring, comprising the following steps: machining the outer ring and toothed ring, machining the inner ring, machining the inner cage and outer cage, and assembling the wheel hub bearing. This invention not only facilitates automated assembly between the steel balls and the inner and outer cages, but also enables clamping between the outer ring, inner ring, and cage, significantly improving the manufacturing efficiency of the wheel hub bearing, reducing the scrap rate, and featuring high integration, high product precision, good sealing performance, and easy installation. It can be used in conjunction with external sensors to improve product safety performance; it can effectively improve the wheel hub bearing's ability to withstand axial and radial loads, featuring a compact structure, small size, and the ability to withstand combined radial and axial loads; it can effectively improve the product's sealing performance and resistance to external contaminant ingress, and effectively prevent internal grease leakage, featuring good sealing effect and long service life.
