A combined loading kinematic joint bearing testing machine

Abstract

The invention relates to a combined loading motion joint bearing testing machine, and belongs to the technical field of bearing test detection. A clamping tool is fixed on a workbench through a bolt; a transverse torsion mechanism is in fixed connection with the left end of the workbench through a screw; an axial loading mechanism is in fixed connection with the right end of the workbench through a bolt; a lateral swing mechanism is fixedly connected with the rear end of the workbench by a screw; four columns are mounted on the upper surface of the workbench; a connecting beam is mounted on the upper ends of the columns; and a first oil cylinder is fixedly connected with the upper end of the beam through a screw. The combined loading motion joint bearing testing machine is advantaged in that the structure is novel; a swing actuator and a linear actuator as executing power elements realize axial and radial loading and revolution and inclined swinging; synchronous and asynchronous coordinated operation can be performed so as to simulate loaded and moving states of a centripetal joint bearing, detect and display the load, the friction coefficient, the wear extent, the temperature, the number of movements, the time and the sliding distance in real time and can simulate the working environment of the sample bearing in a real mode.

Description

technical field [0001] The invention belongs to the technical field of bearing testing and detection, and mainly relates to a testing machine for kinematic joint bearings. Background technique [0002] As an important part of sliding bearings, radial joint bearings are widely used in aerospace, rail cars, mines, metallurgy, heavy vehicles, water conservancy and hydropower and other fields. It consists of an outer ring with an inner spherical surface, an inner ring with an outer spherical surface and Padded composition. During use, the radial spherical plain bearing mainly bears radial load, axial load, rotary swing, and lateral swing. The wear of the bearing liner is an important factor leading to the failure of the radial spherical plain bearing. The cause of the wear of the liner is opposite The research on radial spherical plain bearings plays a vital role. At present, the radial spherical plain bearing testing machines in China are mainly loaded in the axial and radial ...
