Abstract: In response to the frequent occurrence of overload starting and operation during the operation of coal mine belt conveyors, as well as the high temperature, leakage, environmental pollution, and difficulty in maintenance of traditional transmission connection devices such as hydraulic couplers and ordinary couplings used in conveyor transmission systems during operation, a mining torque limited permanent magnet magnetic coupler was designed, which achieved power
transmission between the driving motor end and the working load end through non-contact relative motion between the conductor disk and the magnet disk. It had outstanding advantages such as low neutral requirements, environmental protection and energy conservation, efficient transmission, and easy maintenance. It could also achieve soft start of the driving motor and had overload protection function. By applying permanent magnet torque limited coupler instead of hydraulic couplers and improving the drive system of belt conveyors, the reliability and stability of coal mine transportation equipment can be guaranteed, energy conservation and consumption reduction can be achieved, which meets the performance requirements of intelligent and automated production equipment in coal mines.
