Ball bearing assembly

Abstract

A ball bearing assembly is formed by coupling at least two units together in an axially abutting manner in which a set of multiple spherical balls are installed between at least one pair of adjacent two units. Each unit is formed in an annular shape to form a circular axial central hole inside. A set of multiple hemispherical seats are separately and concavely formed on at least one of two opposite end surfaces of the unit so as to place the set of multiple balls therein. Hemispherical centers of the set of multiple seats are located on the end surface at a concentric circle around the axial central hole to allow each ball inside adapted to be partially protruded from a wall surface of the axial central hole. In the assembly, a spinning shaft is axially run through and radially supported by at least one set of multiple balls.

Description

technical field [0001] The invention relates to the technical field of bearings, especially a novel bearing structure with sustainable lubrication and excellent rolling mechanism of balls. At least one set of multiple balls radially supports the shaft core, greatly improving bearing performance and axial load thrust capacity, and is suitable for Long-term stable operation of ball bearing assemblies under severe operating conditions. Background technique [0002] Under severe operating conditions such as high loads, high speeds, and high vibrations, sliding bearings usually have a weak overall structure, insufficient wear resistance, and depletion of lubricating media within a short period of time, resulting in damage to the grinding interface, resulting in shaft failure. The high-frequency knocking and collision between the core and the shaft hole will cause excessive wear and heat, and the contact pressure and speed limit (PV limit) of the bearing will drop rapidly, and noi...

AI Technical Summary

Problems solved by technology

[0006] However, none of the above-mentioned bearings has a sustainable lubrication mechanism and a mechanism to strengthen the rotation of the ball or cylinder, and it is difficult to maintain stable operation with low friction for a long time. solution to problems such as motion, and the complex structure not only increases the cost and is not conducive to heat dissipation, but also weakens the practicability and mass production; therefore, it is desired to operate it under the above-mentioned severe operating conditions, especially when the PV limit value is greater than 500 MPa ‧m / min will be severely challenged
