Double row wheel hub bearing with stop ring

Abstract

The invention relates to the technical field of bearings, in particular to a double row wheel hub bearing with stop ring. In some automobiles, as it is necessary to prevent the bearing from playing ina bearing pedestal, it is needed to mount the stop ring on an outer ring. A retainer ring type stop ring is mounted on the outer ring ordinarily, and the stop ring is easy to loosen when an automobile rotates at a high speed. According to the double row wheel hub bearing with the stop ring, an inner ring is arranged by pasting a first inner ring and a second inner ring oppositely, the first and second inner rings and a retainer are separately provided with protruding steps, and a cylindrical surface at one end of the second inner ring extends outside an end surface of the outer ring. The double row wheel hub bearing further comprises a seal ring assembly and a magnetic ring assembly. The stop ring is arranged on the outer ring, the stop ring is pasted to the outer ring radially and axially, and a clamping part extending obliquely outward is further arranged in the circumferential direction of the stop ring. The clamping part prevents the bearing from playing in the bearing pedestal inoperation effectively and fixes the bearing effectively. Various barriers due to coaxiality of parts are improved, and the bearing is more stable to operate, does not loosen in high-speed operation and is long in service life.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a double-row hub bearing with a stop ring. Background technique [0002] Hub bearings are one of the key components of automobiles. They can not only carry axial loads but also radial loads, bear weight and provide precise guidance for the rotation of hubs, so they are widely used in automobiles. However, in the prior art, the length of the opening outside the bearing along the axial direction of the bearing is relatively short, which increases the risk of external pollutants intruding into the accommodation gap and further into the inside of the bearing. However, in some automobile transmission parts, it is necessary to prevent the bearing from moving in the bearing seat during operation, and it is necessary to install a stop ring on the outer ring. Generally, a stop groove is opened on the outer ring of the bearing, and then a snap ring type stop ring is installed. This kind ...

AI Technical Summary

Problems solved by technology

Generally, a stop groove is opened on the outer ring of the bearing, and then a snap ring stop ring is installed. This kind of stop ring is easy to loose when the car rotates at high speed, which reduces the service life of the bearing.
