Slip-type torque testing platform

The invention provides a slip-type torque testing platform, which is characterized by comprising a slip speed regulator arranged on a base, and a balancing beam type weighing sensor connected with the input shaft end of the slip speed regulator is arranged on the base through a moment equalizer; a speed measuring device is arranged on the output shaft end of the slip speed regulator, the output shaft end is connected with a testing motor provided with a frequency changer through a coupling, and the testing motor is arranged on the base through an engine base; and a special regulator is connected with the weighing sensor and the speed measuring device. The device provided by the invention overcomes the defects of the prior art and utilizes the slip speed regulator and the special regulator of a serial regulation system to quickly and precisely measure the torque and rotating speed of the frequency changer, and the device is simple in structure, low in cost and liable to maintain and generalize.
