Bearing

Abstract

The invention discloses a bearing, the structure of which comprises an outer ring, a sliding ball, a bearing protective cover, an inner ring protective cover, an inner ring, an axial surface, and a grease nipple. The outer ring has a circular structure, and an axial surface and In one structure, there are two protective sleeves parallel to each other. The protective sleeves are respectively nested on the left and right sides of the outer ring. There are more than two sliding balls. The sliding balls are evenly and equally spaced inside the outer ring with clearance fit. The ring protective sleeve has a circular structure, the inner ring protective sleeve is respectively nested on the inner side of the bearing protective sleeve, the inner ring is set in the middle of the outer ring as an integral structure, and the oil nozzle is nested on the shaft surface and has an interference fit. Beneficial effects: the structure is equipped with a grease nipple. When in use, the screw under the nut can be screwed into the inside of the shaft surface, and then the sliding ball inside the outer ring can be filled with lubricating oil through the grease nipple hole on the nut, so that it can be more Good use, not easy to rust, long service life.

Description

technical field [0001] The invention is a bearing and belongs to the field of bearings. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. [0003] The prior art discloses a bearing with the application number: 201110431395.7, which includes: an inner ring, a secondary inner ring tightly fitted on the inner ring, rollers distributed on the secondary inner ring, and a pair of adjacent rollers The rollers in between, the ring-shaped hoop set on each roller, the secondary outer ring tightly fitted on the bridge hoop, and the outer ring tightly fitted on the secondary outer ring; the axial distribution of the rollers , each roller is provided with an annular groove with an arc-shaped cross section, and the rollers are located between the annular grooves of adjacent rollers; the inner...
