Electromechanical coupling system for preventing a mechanical device from operating beyond preselected operating parameters or control parameters

摘要

An electromechanical coupling system for operating a mechanical device within preselected parameters and comprising a sensor means which generates control pulses corresponding to the operating parameter sensed, an electronic control unit which is connected to the sensor means electrically and generates enabling pulses in proportion to the control pulses when the operating or control parameter of the mechanical device is within preselected values and suppresses the enabling pulses otherwise, and a coupler means located between a drive unit and a driven unit of the mechanical device for decoupling the drive unit from the driven unit when the enabling pulse is suppressed and coupling them together when the enabling pulse is present.
