Retainer ring for compensating axial clearance and use thereof

Abstract

The invention discloses a retaining ring which can compensate axial space; the retaining ring is an open-typed retaining ring, and comprises a thrust face and an outer ring surface; the retaining ring is characterized in that: the retaining ring also has a sliding surface, the shape of the cross section of which is wedge-shaped. The preferable value of the included angle between the sliding surface and the thrust face is 5-25 degrees. Suitable included angle slope is determined according to the axial force and the friction coefficient of the sliding surface of the retaining ring. Simultaneously, the shape of an installation groove of the retaining ring is modified correspondingly and changed into an inclined place with the same inclined angle by coordinating with the sliding surface, so the retaining ring which adapts to the installation groove of the retaining ring can slide and regulate the space automatically. The application of a retaining ring which can compensate axial space is used axially and fixedly by the steering input gear shaft of a gear rack type machinery redirector which is widely used in micro cars or light cars. The test and the actual operation prove that the retaining ring has good axial space compensation function, reduces the axial coordinating space and the axial movement value of the gear when in work, removes the abnormal meshing sound, and improves the working performance and reliability of the redirector.

Description

technical field [0001] The invention relates to a retaining ring, in particular to a retaining ring for axially fixing the steering input gear of a rack-and-pinion mechanical steering gear widely used in miniature and light automobiles. The pinion axially fits the clearance and the axial movement during operation to improve the working performance of the steering gear. Background technique [0002] The rack and pinion mechanical steering gear is widely used because of its simple structure, low cost, high transmission efficiency, small size and easy vehicle layout, especially on economical cars and mini cars. However, the current market feedback indicates that with the continuous improvement of the three-guarantee period for complete vehicle products, the failure rate of the rack-and-pinion mechanical steering gear, which is a major safety component, is increasing during the three-guarantee period, mainly manifested as abnormal steering noise. In fact, the causes of failure ...

AI Technical Summary

Problems solved by technology

2. The gap between the gear and rack meshing parts is too large after running-in, and the axial movement of the gear is too large

None of the existing technical solutions can eliminate the fit clearance in the axial direction, so that the gear shaft can move under the action of the axial component force in the working state, thereby reducing the smoothness of the gear rack meshing and increasing the Normal wear and tear, accompanied by abnormal rotation noise
