WAVEFORM HYDRAULIC MOTOR Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: hydraulic motor uses a flexible and rigid wheels, gear-type coupling, plunger waveform generator and a distributer in the form of a disk with bores. The latters are positioned on different disk diameters. Axial bores, connected by working medium feed and drain spaces, are located on the end face of the waveform generator. During disk rotation the flow of working medium is redistributed in the waveform generator, whose plungers move as a result of pressure differential, deform the flexible wheel and generate deformation waves and develop a torque at the flexible wheel, which is transmitted to the motor output shaft. EFFECT: improved design.
