Automobile hub bearing unit sealing ring sealing performance testing machine

Abstract

The invention discloses an automobile hub bearing unit sealing ring sealing performance tester, which comprises a rack, and a main shaft component, a simulated bearing component, an inclination angle adjustment mechanism and a slurry pond containing test intervention slurry arranged on the rack, wherein the main shaft component comprises a motor and a main shaft, the motor and the main shaft are in transmission connection, and the main shaft can swing around the rotation shaft on a main body above the rack; the simulated bearing component comprises a simulated outer ring, a sealing ring and a simulated inner ring, the simulated outer ring is arranged on the main body, the simulated inner ring is arranged on the main shaft, the relative position between the simulated outer ring and the simulated inner ring is determined, and the sealing ring is arranged between the simulated outer ring and the simulated inner ring; and the inclination angle adjustment mechanism comprises an inclination angle slight adjustment mechanism and a swinging arm, when the inclination angle slight adjustment mechanism is adjusted, the swinging arm, the motor and the main shaft rotate around the rotation shaft at the rotation shaft place relative to the main body, and an inclination angle is generated between the axis of the simulated outer ring and the axis of the simulated inner ring. Thus, the working life reflecting the sealing performance of the sealing ring can be acquired through a test.

Description

technical field [0001] The invention relates to a sealing performance testing machine for the sealing ring of an automobile hub bearing unit. Background technique [0002] The working environment of the automobile hub bearing is harsh. Both sides of the hub bearing are sealed with special sealing rings to prevent dust, water, mud and other foreign matter from entering the inside of the bearing, thereby polluting and corroding the internal raceways and rolling elements of the hub bearing, thereby Guarantee the working performance and service life of the bearing. Therefore, the sealing performance of the sealing ring is particularly important for the hub bearing. [0003] The structure of the automobile hub bearing: the automobile hub bearing is composed of an inner ring, an outer ring and two rows of rolling elements. The two rows of rolling elements are between the inner ring and the outer ring. The relative positional relationship, that is, the axis of the inner ring and ...
