A new type of intelligent torque-limiting safety coupling and its working method

Abstract

The invention proposes a novel intelligent torque-limiting safety coupling and its working method. The control system analyzes the dynamic torque data on the coupling detected by the sensor component, and when the torque on the coupling exceeds the preset value of the control system When the value is set, the control system sends an instruction to the actuator, and the action of the actuator makes the left half coupling and the right half coupling quickly disengage, realizing the function of limiting torque; the actuator is embedded in the coupling, and one end of the cylinder piston rod is sleeved There is a spring and extends into the hydraulic oil cylinder, and the other end of the piston rod of the oil cylinder is connected with the steel ball, which can drive the steel ball to extend or retract. The new intelligent torque limiting safety coupling controls the dynamic clutch of the left half coupling and the right half coupling to realize the torque limiting function by detecting the actual torque. It has short response time and high intelligence, and can realize independent self-control. , and can be connected with external electronic devices or cloud devices to realize data transmission and external control.

[0007] The requirements of the market for torque-limiting couplings (safety couplings) are: the error between the disengagement torque of the coupling and the actual torque on the coupling is small, intelligent, remote control, instantaneous dynamic complete disengagement, non-stop Dynamic recovery, the newly developed equipment needs to collect and analyze the actual torque data on the transmission system. It is best to predict the torque change trend based on historical data and real-time torque curves, so as to deal with it in advance. In this context, the traditional Mechanical safety couplings are increasingly unable to meet the needs of the market
