Claim 1:
2. A method of applying the testing device for testing the precision retaining ability and fatigue life of RV reducer according to claim 1, characterized in that: the servo motor (4) drives the RV reducer (6) to rotate, and the output planet carrier of the RV reducer (6) drives the extension arm (8) and the simulated swing arm (9) to swing back and forth; the first displacement sensor (11) is used to measure position information of the first counterweight block (10) when the first counterweight block (10) swings to a lowest point, during entire life cycle of the RV reducer (6), positioning accuracy, repeat positioning accuracy and wear of the RV reducer (6) are measured in real time; then a numerical fitting algorithm is used to calculate the precision retaining ability and fatigue life of the RV reducer (6);
the second displacement sensor (15) is used to measure the height of the detection rod (14), then a tilt angle of the output planet carrier of the RV reducer (6) under different rotational positions and different loads is determined; after a specified time of operation, bending stiffness of the RV reducer (6) and the wear in tilt direction are measured in real time.
