Abstract
The invention relates to an escalator drive shaft tensioning sleeve torque test device comprising a fixation mount, a screw, a friction force measuring instrument, a gripping sleeve, a transmission rod and a force applying bolt. The screw is fixed on the fixation mount. The friction force measuring instrument is connected with the gripping sleeve. The gripping sleeve is connected with the screw through the transmission rod. The tensioning sleeve to be tested is arranged in the gripping sleeve. The force applying bolt is connected with the screw. The movement of the screw is driven by tightening the force applying bolt, the gripping of the gripping sleeve is driven by the movement of the screw to stop the moving tensioning sleeve, and the friction force measuring instrument is used to display the maximum static friction force of the rotation of the tensioning sleeve. Compared with the prior art, the escalator drive shaft tensioning sleeve torque test device of the invention has advantages of high measurement accuracy, convenient operation and low implementation cost.
