MOVING ASSEMBLY IMBALANCE CONTROL DEVICE Russian patent published in 2009 - IPC G01M1/16 

FIELD: instrument engineering.

SUBSTANCE: invention refers to balance equipment and can be used to control the imbalance characteristics of a moving assembly e.g. beam-type. The object in view is ensured by that the device comprises a base with a vibrator, a liquid tank and an imbalance compensator comprising pilot-operated valves mounted on the base and microswitches connected to the valves, and support arms attached to the controlled assembly and interacting with microswitches, and provided with complementary graduate tanks for collection of liquid discharged from the valves. The complementary tanks are fixed on the moving beam-type assembly and provided with tapered walls with angle of taper exceeding rotation of the moving assembly. Besides, the complementary tanks can be pivoted on the moving beam-type assembly with their centres of gravity positioned below the hinge pivot vertically. The neck width double exceeds their displacement horizontally if the moving assembly turns.

EFFECT: high-accuracy imbalance control of the moving beam-type assembly.
