Problems solved by technology

Although ball bearings have the advantages of low friction, can withstand radial and axial forces, and have low environmental requirements, they have complex structures, low speeds, and short lifespan. It is obviously more difficult to quickly replace existing full-floating bearings in the supercharger market. Disaster

Abstract

The invention relates to a full-floating ball bearing, which includes a bearing body and a spring ring. At least one circle of through holes is arranged on the side wall of the bearing body along the axial direction, and each circle of through holes is uniformly arranged around the circumference. There are at least three evenly arranged through holes in each ring of through holes, in which are arranged balls that move radially along the bearing body, and ring grooves are arranged on the bearing body corresponding to the positions of each ring of through holes , a spring ring in contact with the ball is installed in the ring groove. The invention can partially dynamically control the rotating shaft, the comprehensive friction is smaller, and the running resistance at high speed is significantly reduced, which meets the higher requirements of the existing full floating bearing application, and at the same time expands more fields for this durable and affordable bearing. application.

Description

technical field [0001] The invention relates to the field of full floating bearings, in particular to a ball full floating bearing. Background technique [0002] The full floating bearing is a commonly used bearing in the automobile industry. The full floating bearing is actually a ring set on the rotating shaft. There are gaps between the ring and the shaft as well as between the ring and the bearing seat. It is filled with lubricating oil with a pressure of 0.25-0.4Mpa. These two gaps form a double layer of oil film, and the floating bearing rotates in the same direction as the rotor shaft in the oil film. Compared with ball bearings, full-floating bearings are simple in structure, durable and affordable, and are mainly used in high-speed occasions where they only transmit torque and do not bear any reaction force or bending moment. But its shortcomings are also obvious. First, its high-speed running resistance is large, which affects the speed-up response of the rotating...
