The invention discloses a device for detecting torsional rigidity and return difference of a precision planetary reducer. The device comprises a machine body, a loading unit, a measuring unit and a locking mechanism, wherein the locking mechanism is arranged matched with the machine body and used for being connected with the input end of the detected reducer to lock the reducer. Continuous loading application can be achieved within the range larger than the rated load torque through the loading unit, the value of torque applied to an output shaft of the detected reducer can be detected through the a torque sensor, the situation of changes of turning angel of the output shaft can be detected through an angle sensor on the output shaft, and therefore the torsional rigidity and return difference of the detected reducer are figured out.
Description
technical field [0001] The invention relates to the technical field of precision gear transmission performance measurement, in particular to a precision planetary reducer torsional stiffness and hysteresis detection device. Background technique [0002] With the continuous improvement of my country's scientific and technological innovation level and scientific research strength, various industries have put forward higher requirements for the performance of precision reducers.
