Coordination structure device of high-revolving-speed bearing and balls of high-revolving-speed bearing

Abstract

The invention discloses a coordination structure device of a high-revolving-speed bearing and balls of the high-revolving-speed bearing, and relates to the technical field of bearing machining and manufacturing. According to the coordination structure device of the high-revolving-speed bearing and the balls of the high-revolving-speed bearing, the solid balls and the hollow balls are distributed between a bearing inner ring and a bearing outer ring in a staggered mode at equal intervals; the ball outer diameters of the hollow balls are greater than the ball diameter sizes of the solid balls; the contact layer surface of the bearing inner ring and the solid balls as well as the hollow balls is provided with a first contact layer; and the contact layer surface of the bearing outer ring and the solid balls as well as the hollow balls is provided a second contact layer. According to the coordination structure device of the high-revolving-speed bearing and the balls of the high-revolving-speed bearing, the solid balls and the hollow balls are mounted and arranged between the bearing inner ring and the bearing outer ring in the staggered mode, under the condition that ball supporting force is ensured, even distribution of contact force applied to the bearing inner ring and the bearing outer ring is achieved, abnormal abrasion of the bearing is reduced, and stable operation of the bearing is ensured.

Description

technical field [0001] The invention belongs to the technical field of bearing processing and manufacturing, and in particular relates to a high-speed bearing and a matching structure device for balls thereof. Background technique [0002] The use of bearings on mechanical equipment is extremely common. In some equipment, it is necessary to use bearing components with higher speed. When the rolling bearing moves at high speed, the centrifugal force has a great influence on its life and strength. The excessive wear of the bearing will not only greatly reduce the life of the bearing itself, but also directly affect the use of the equipment using the bearing, resulting in the safety performance and use of the equipment. Performance is greatly reduced. How to reduce the loss of bearings during high-speed motion has become a problem that needs to be solved. Contents of the invention [0003] The purpose of the present invention is to provide a high-speed bearing and a matchi...
