STAND FOR WHEELS AND WHEEL PAIR AXLES DURABILITY TESTING Russian patent published in 2018 - IPC G01M17/10 

FIELD: test equipment.

SUBSTANCE: invention relates to stands for wheels and axles of wheelpairs of railway rolling stock durability testing. Stand contains a motor, a loader with a rotating unbalanced mass, which is installed in the upper part of the tested objects, namely on the technological axis inserted in the central hole of the test wheel, or on the tested axis inserted into the hole of the cantilever-holding hub fixed to the base plate, which is supported by springs on the foundation. Co-axial with the shaft of the loading device is a balancing mechanism with an unbalanced mass rotated with respect to the unbalanced mass of the loading device by 180°, which, by means of the rigid supports holding it, transfers the inertia forces directed to the support plate with respect to the inertia forces generated by the loading device in the opposite direction, which leads to a decrease in the vibration of the support plate.

EFFECT: reducing the weight of the foundation slab and ensuring the possibility of testing on a single slab of several objects.
