PULSE DRIVE Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: arc-like piezoelectric member is included in the drive to play a motor. The member is concentrically mounted between the driving wheels of gear transmissions and interconnects the wheels. Successive wedging of the wheels by one or two controlled pushers is performed in agreement with the discrete feeding of electric power to the piezoelectric member and results in alternate rotation of the wheels and subsequent compression of the piezoelectric member. If the starting order of the wedging of the wheels is changed, rotating members will rotate in opposite directions. EFFECT: improved design. 3 dwg
