Development and Application of ZJ50DB Oil Drilling Rig Direct Drive Rotary Drive Device
The turntable drive device is one of the core components of oil drilling rigs.The conventional turntable drive device is driven by a high-speed AC variable frequency motor through a gear reducer to work on the turntable.The ZJ50DB oil drilling rig developed in this article adopts a low-speed and high torque AC variable frequency motor to directly drive the turntable,eliminating the need for a large transmission mechanism gear reducer,simplifying the transmission mode,reducing intermediate fault points,and reducing maintenance costs.The overall size is small,the weight is light,and it is convenient for disassembly and transportation.
