Problems solved by technology

Both require the motor to provide periodically repeated positive and negative torque; the kinetic energy required for load acceleration is completely provided by the motor, and the kinetic energy is consumed on the braking resistor when decelerating, and even consumes energy for reverse braking; Compared with direct drive, the efficiency is higher and the cost is lower, but the transmission law is complicated, the precision is low, and problems such as lubrication, maintenance, life, and noise are difficult to solve; the direct drive of the motor has high precision and good dynamic performance, but the cost is high, the current is large, and the control is difficult

Description

technical field [0001] The invention belongs to the electromechanical field, in particular to a device for driving a load to reciprocate around an axis. Background technique [0002] In the fields of industrial production, scientific research and national defense, there are a large number of large loads that reciprocate around the axis, many of which have the characteristics of large mass, large size, and short reciprocating period. When this type of load reciprocates around the axis, it needs to overcome a large moment of inertia or obtain a large angular acceleration. Therefore, it is necessary to periodically load a large driving torque on the load. [0003] The driving schemes for these loads can be divided into two categories, mechanical transmission and motor direct drive. Mechanical transmission includes the motor driving the linkage mechanism to drive the rotating shaft, and the motor output decelerates to drive the rotating shaft, etc.; the direct drive of the moto...
