Four-point contact bearing with high axial load

By designing a high axial load four-point contact bearing, using a nylon cage and steel ball structure, and combining it with a lubrication hole design, the technical problems of traditional four-point contact bearings have been solved. This enhances the radial load and overturning moment bearing capacity, solves the problem of the difficulty in bearing high axial loads in existing technologies, achieves high axial load bearing capacity, simplifies the requirements for processing equipment, and reduces R&D costs.

Abstract

The utility model discloses a four point contact bearing of high axial load, including bearing outer ring, the inside of bearing outer ring is provided with bearing inner race, is provided with raceway between bearing outer ring and bearing inner race, and the inside of nylon retainer is installed with steel ball, both ends of raceway all are installed with sealing ring. The utility model discloses the four point contact of this contact bearing replaces the two point contact of groove bottom, and the contact angle of this product is 35 DEG, can increase radial rated dynamic load and radial rated static load simultaneously, can also bear certain axial load and overturning moment, and with the increase of contact angle, the axial load and overturning moment that can bear also increase along with it, but the contact angle usually does not exceed 45 DEG, and the processing equipment of this contact bearing also does not need to add, only on the basis of original equipment, the shape of grinding wheel is modified into the groove shape of four point contact to meet the requirement of product.
