Retainerless automobile bearing

Abstract

The invention discloses a retainerless automobile bearing, which comprises a bearing inner race, a bearing outer race, a spherical roller and a retainer. The internal surface of the bearing outer raceis provided with a circle of sunken arc-shaped upper groove. The external surface of the bearing inner race is equipped with a circle of arc-shaped lower groove. The bearing inner race is arranged inside a central hole of the bearing outer race. The spherical roller is erected between the arc-shaped upper groove and the arc-shaped lower groove. A permanent magnet layer is embedded in the bottom end of the arc-shaped upper groove and the arc-shaped lower groove. Upper and lower ends of the spherical roller are in sliding contact with the permanent magnet layer. The left edge of the arc-shapedupper groove and the right edge of the arc-shaped lower groove are both connected with a rotating shaft. The left edge of the bearing outer race and the right edge of the bearing inner race are sunkeninwards and provided with a dead plate receiving groove. Through the above mode, stable rotation of the roller in a bearing also can be maintained without a retainer structure.

Description

technical field [0001] The invention relates to the field of automobile bearings, in particular to an automobile bearing without a cage. Background technique [0002] The cage refers to the bearing part that partially wraps all or part of the rolling elements and moves with them to isolate the rolling elements, usually guide the rolling elements and keep them in the bearing. When the rolling bearing is working, especially when the load is complex and rotates at high speed, the cage has to bear a lot of centrifugal force, shock and vibration, there is a large sliding friction between the cage and the rolling elements, and a lot of heat, force and heat are generated The result of the joint action will lead to failure of the cage. In severe cases, it will cause burns and fractures of the cage. Under the condition of satisfying the stable rotation of the rollers, the cage is not an unnecessary structure of the bearing. If the structure of the cage can be reduced , then the cost...

Problems solved by technology

When the rolling bearing is working, especially when the load is complex and rotates at high speed, the cage has to bear a lot of centrifugal force, shock and vibration, there is a large sliding friction between the cage and the rolling elements, and a lot of heat, force and heat are generated The result of the joint action will lead to failure of the cage. In severe cases, it will cause burns and fractures of the cage. Under the condition of satisfying the stable rotation of the rollers, the cage is not an unnecessary structure of the bearing. If the structure of the cage can be reduced , then the cost and production speed of the bearing will be greatly improved
