The invention discloses a hybrid drive rotation control system which comprises a control unit, a hydraulic motor and a rotation motor, and the hydraulic motor and the rotation motor are connected with a rotation bearing through two rotation speed reducers respectively. And the control unit is used for controlling the hydraulic motor and the rotary motor to independently drive the rotary support or controlling the hydraulic motor and the rotary motor to output power in proportion to drive the rotary support. Through hybrid driving of the hydraulic motor and the rotary motor, the problems that a hydraulic rotary system is poor in starting characteristic and a motor rotary system is poor in load fluctuation resistance are solved, the starting and stopping control characteristic and process movement stability of the rotary system are improved, and the product controllability level is improved.
本发明公开了一种混合驱动回转控制系统,包括控制单元、液压马达和回转电机,所述液压马达和回转电机分别通过两个回转减速机与回转支承连接,所述控制单元用于控制液压马达和回转电机单独驱动回转支承或者控制液压马达和回转电机按比例输出动力驱动回转支撑。通过液压马达和回转电机的混合驱动,解决液压回转系统启动特性不好及电机回转系统抗负载波动能力差的问题,提升回转系统启停控制特性及过程运动平稳性,提升产品操控性水平。
