POWER DRIVE FOR WORKING ORGAN OF INDUSTRIAL MACHINE

摘要

A power drive for the working organ of an industrial machine is mounted on its support frame (6) and comprises a multi-element planetary mechanism (24) and a driving motor (23). The input shaft (26) of the mechanism (24) is connected to the shaft (27) of the driving motor and the output shaft (4) is kinematically connected to the working organ (1) of the machine. The power drive (22) is provided with a means for protection against static and dynamic overloading, which consists of a volume hydromachine (40) mounted, together with its high-pressure line (42) and low-pressure line (43), on the support frame (6) of the industrial machine. The shaft (44) of the volume hydromachine (40) is connected, through a transmission, to an element (29) of the planetary mechanism (24) accepting its reactive torque.
