STAND FOR TESTING FRICTIONLESS BEARING FOR DURABILITY Russian patent published in 2009 - IPC G01M13/00 

FIELD: physics, testing.

SUBSTANCE: invention relates to the field of test engineering, particularly to testing radial frictionless bearings for durability during local loading. The stand includes a support frame with a case mounted on it in the form of a cylinder and two end shields. Mounted on the case is a shaft with four bearing - two for testing and two accessorial. Two load levers pivotally connected with the case of the stand. A load lever with a load through a telescopic prop, load plug coupler and the accessorial bearing form a load on the shaft, and the shaft - a load on the internal ring of the bearing being tested. Rotation of the shaft stand takes place due to the fact that, an armature is pressing on the shaft, and on the case of the stand has been put the stator coil of the asynchronous motor, which allows to exclude external transmission.

EFFECT: increasing precision of results of testing and design simplification of the stand for testing radial bearings with local loading for durability.
