High-speed sealed bearing

Abstract

The invention relates to a high-speed sealed bearing, comprising an inner ring, an outer ring, a ball and a maintenance rack. An inner raceway is arranged on an external surface of the inner ring, and an outer raceway is arranged on an interior surface of the outer ring; the inner raceway and the outer raceway form a complete ball raceway; the ball is arranged on the ball raceway; the maintenancerack is arranged outside the ball; a first dustproof groove and a second dustproof groove are arranged on the inner surface of the outer ring, wherein the first dustproof groove is equipped with a first dustproof loop, and the second dustproof groove is equipped with a second dustproof loop; an inner wall of the first dustproof loop and the external surface of the inner ring are separated by a distance; and an inner wall of the second dustproof loop and the external surface of the inner ring are separated by a distance. The high-speed sealed bearing of the invention can substitute a mist lubrication system of a bearing, so as to simplify design and manufacture of a lubricating system of machinery equipment and raise dustproof effect and grease leakproof effect of a bearing.

Description

technical field [0001] The invention relates to a high-speed bearing, in particular to a high-speed sealed bearing. Background technique [0002] The lubrication of high-speed bearings is generally lubricated with oil mist, which requires that equipment manufacturing must be designed with an oil lubrication system. At present, with the improvement of technology, it is difficult to design an oil lubrication system in many working environments, which requires the bearing to be lubricated with grease. Grease lubrication is the addition of lubricating grease to the bearing grooves. The four major parts of a bearing are the outer ring, inner ring, steel balls and cage. The function of grease is to lubricate the bearing raceway, and the function of the bearing seal and sealing structure is mainly to protect the grease. At present, deep groove ball bearings have open and sealed structures, while high-speed angular contact bearings have not yet been designed with sealed structure...
