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.
