Service performance testing device suitable for solar speed reducer

The utility model provides a service performance detection device suitable for a solar speed reducer. The service performance detection device comprises a hand-cranking elevator, a driving unit, an output conversion shaft, a telescopic force arm and a hydraulic machine. The driving unit is installed on the hand-cranking elevator and can be driven by the hand-cranking elevator to move up and down in the vertical direction. One end of the output conversion shaft is connected with an output worm gear of the solar speed reducer, the other end is fixed to the first end of the telescopic force arm, and the hydraulic machine is arranged at the second end of the telescopic force arm and used for applying downward force to the telescopic force arm. The service performance testing device can realize the installation and fixation of the solar speed reducer, the reciprocating driving of the input shaft and the torque adjustment of the output shaft, can meet the requirements of most solar speed reducers on the holding tor
