Novel intelligent torque-limiting safety coupling and working method thereof

Abstract

The invention provides a novel intelligent torque-limiting safety coupling and a working method thereof. A control system analyzes dynamic torque data, detected by a sensor assembly, on the coupling,and when the torque on the coupling exceeds a preset value of the control system, the control system sends an instruction to an executing mechanism, the executing mechanism acts to enable a left halfcoupling and the a half coupling to be separated quickly, and the torque limiting function is achieved; the executing mechanism is embedded in the coupling, one end of an oil cylinder piston rod is sleeved with a spring and stretches into a hydraulic oil cylinder, and the other end of the oil cylinder piston rod is connected with a steel ball and can drive the steel ball to stretch out or retractback. According to the novel intelligent torque-limiting safety coupling, dynamic clutch of the left half coupling and the right half coupling is controlled through detection of the actual torque to achieve the torque-limiting function, the response time is short, the intelligent degree is high, independent self-control can be achieved, and the coupling can be connected with external electronic equipment or cloud equipment to achieve 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
