Air bearing capable of preventing light-load abrasion

Abstract

The invention relates to the technical field of bearings, particularly relates to an air bearing capable of preventing light-load abrasion, and solves the problem that at present, for some special occasions such as a fiber thread passing device of a textile machine, pressure of fibers on a bearing is very small, pressing force needs to be externally added for preventing a steel ball from slippingrelative to an inner ring and an outer ring of the bearing, but friction force of the bearing is increased. According to the air bearing, baffle rings are arranged on the outer diameters of the two ends of a bearing inner ring correspondingly, a flow equalizing ring groove is formed in the center of the inner wall of the bearing inner ring, air spraying openings are evenly formed in the center ofthe outer diameter of the bearing inner ring, air passing holes are formed between the flow equalizing ring groove and the air spraying openings, an air inlet channel is formed between the flow equalizing ring groove and the end face of the bearing inner ring, an air pipe joint communicates with the air inlet channel, third oblique faces are arranged on the inner sides of the baffle rings, secondoblique faces are arranged on the two sides of a bearing outer ring and are parallel to the third oblique faces, a flow dividing sharp corner is arranged in the center of the inner wall of the bearingouter ring, and arc-shaped ring grooves are formed in the two sides of the flow dividing sharp corner, so that abrasion of the bearing and increase of the friction force are effectively prevented.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to an anti-light-load wear-resistant air bearing. Background technique [0002] Bearing is one of the commonly used parts in modern industrial machinery. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load during the transmission process of the equipment. Bearings have a minimum bearing capacity to prevent steel balls from slipping relative to the inner and outer rings of the bearing, and the wear is aggravated. Slipping with the inner and outer rings of the bearing requires an external pressing force, but it leads to an increase in the friction of the bearing. Contents of the invention [0003] The purpose of the present invention is to provide an anti-light-load wear-resistant air bearing to solve the problems of severe bearing wear and high friction. [0004] A light-load wear-resistant air bearing of the present...
