Abstract
In view of the problems existing in the power end drive mechanism of conventional beam pumping units, the power end drive mechanism has been improved through optimized design. Abandon the belt and gearbox and replace it with a crankshaft and universal coupling, which can increase the motor torque and improve the transmission efficiency of the system. The asynchronous motor is changed to a permanent magnet synchronous composite motor, which realizes direct drive, low speed and large torque, and reduces the energy consumption and failure rate of the whole machine. Based on the dynamics and balance mechanism, the multi-body dynamics analysis of the pumping unit is carried out.
