STAND FOR TESTING PLATED BEARINGS Russian patent published in 2022 - IPC G01M13/04 

FIELD: testing equipment.

SUBSTANCE: invention relates to testing equipment and can be used to test spherical bearings with simulation of operating loads and temperatures. The stand for testing spherical bearings consists of a base on which a drive and a load device are placed and connected by means of a kinematic chain, while the axis is pivotally mounted in the base. The base consists of a frame and a base plate containing a bushing, pivotally mounted in the lower part of the frame. The load device is installed in the lower part of the frame and contains a power unit pivotally mounted on the frame, a spring-loaded rod mounted in the base plate bushing with the possibility of movement, and a rocking chair mounted on the frame with the possibility of rotation. One end of the rocker is pivotally connected to the piston ear of the power unit, and the other end is pivotally connected to the rod. The drive and axle are mounted on the top of the frame. A simulator is installed on the axle, containing a right flange, which is pivotally connected to one end of the axle, and a left flange, pivotally connected by means of a bearing to the other end of the axle. The left flange is kinematically connected to the base plate by means of a rod, one end of which is pivotally connected to the central part of the base plate, and the other end is pivotally connected by means of a bearing to the left flange. The drive rod is pivotally connected to the rocker, rigidly connected to the shaft, one end of which is mounted for longitudinal movement in the body, rigidly fixed on the upper part of the frame, and the other end is rigidly fixed on the right flange of the simulator. Heating elements are located outside the left flange.

EFFECT: invention provides the ability to implement the design of a spherical bearing test bench with simulation of operating loads, movements and temperatures.
