Abstract

The invention discloses a double-row deep groove ball bearing for an automobile steering device. The double-row deep groove ball bearing comprises an outer ring, two inner rings, steel balls and a retainer; each inner ring is provided with a one-row groove; the outer ring is provided with a double-row groove; the retainer is arranged between the two inner rings and the outer ring; the steel balls are arranged on the retainer, and are uniformly distributed between the outer ring and the inner rings; and the bearing is an open bearing. The double-row deep groove ball bearing for the automobile steering device improves the assembly precision, reduces the production cost, improves the axial and radial bearing capacity, reduces the axial and radial displacement, prevents the axial and radial oscillation, finally improves the flexibility, the safety and the comfort of a steering system, and realizes prolonging of the service life of the automobile steering system.

Description

technical field [0001] The invention relates to an automobile steering gear bearing, in particular to a double row deep groove ball bearing. Background technique [0002] The bearing at the upper end of the steering gear is used to support the lower shaft of the steering wheel of the car. At present, a set of bearings is generally used in China for support, and the other end is supported by a needle bearing. This design enables the elimination of axial movement and axial support of the entire system to be undertaken by a single set of deep groove ball bearings. At present, the bearing clearance of the automobile steering system cannot fully meet the requirements of the automobile steering system. When the radial clearance is too large, the axial clearance will increase accordingly, causing the steering wheel to swing during the operation of the system; when the clearance is too small, After assembly, the clearance is likely to be in a state of 0 clearance or negative cleara...
