Tubular motor torque testing device and method

Abstract

The invention discloses a tubular motor torque testing device and a testing method. The tubular motor torque testing device comprises a mounting bracket, a fixing assembly is arranged on the mounting bracket, a testing assembly comprises a transmission, a resistance piece and a speed measurement sensor, and the transmission is arranged on the mounting bracket and is provided with an input end and an output end. A to-be-tested tubular motor is fixed on the installation support through the fixing assembly, the output shaft is connected with the input end of the transmission, and the resistance piece and the speed measurement sensor are arranged at the output end of the transmission at intervals. The tubular motor rotates, the transmission increases or decreases the rotating speed of the tubular motor, the output end of the transmission drives the resistance piece to rotate by overcoming air resistance, the speed measurement sensor measures and calculates the actual output rotating speed of the speed changer, and whether the resistance piece can reach the preset rotating speed or not after being subjected to the effect of the air resistance during rotation is judged, therefore, whether the output torque of the tubular motor reaches the standard is judged. The tubular motor torque testing device is time-saving and labor-saving in operation and higher in testing efficiency.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a tubular motor torque testing device and a tubular motor torque testing method. Background technique [0002] Tubular motors are mostly used in curtains and electric rolling doors. The end of the tubular motor away from the moving shaft is rotated and connected to the limit gear. The tubular motor is hidden in the roll tube. The drive shaft of the tubular motor is fixedly connected to one end of the roll tube. The limit gear of the tubular motor is fixedly connected to the other end of the roll tube. The moving shaft Drive the roller tube to rotate, and the roller tube drives the limit gear to rotate, so as to realize the lifting of the roller blind sheet. When it rises, the sheet is wound on the roller tube, and when it is lowered, the sheet slides down along the inner side of the guide rail. Through the control of the remote control, the curtain can be raised, stopp...

Problems solved by technology

In the related art, the torque of the motor is tested by hanging a heavy object on the output end of the tubular motor to be tested. When testing different tubular motors or testing different torques, it is necessary to replace heavy weights of different qualities. objects, and because the heavy objects are mounted on the output shaft through flexible parts, the test stroke and the space occupied by the test device are also relatively large, and the use of the test device is very inconvenient
