Abstract

The invention provides a fatigue service life testing method of a precise speed reducer for a robot, wherein a repeatedly swinging inertia load component is utilized for simulating an actual working condition of a precise speed reducer for the robot and furthermore testing the fatigue service life of the precise speed reducer for the robot. A device according to the method mainly comprises a testing principle, a swinging loading and controlling system and a data processing system. A tested speed reducer is driven from an input end so that an output end performs repeated swinging. The swingingrange is psi; an acceleration / decelerating angle range is alpha; an equal-speed area angle range is psi-2alpha and is not lower than 0. A normal working highest allowable load of the tested speed reducer is used for quickly evaluating the precise speed reducer fatigue service life, and furthermore an equivalent method between the testing fatigue service life and a continuous stable-state torque loading process tested fatigue service life is established. The precise speed reducer fatigue service life testing method can efficiently and accurately test the precise speed reducer fatigue service life for the robot, and furthermore has advantages of high testing precision and low cost.

Description

technical field [0001] The invention relates to the field of testing precision reducers for robots, in particular to a method for testing the fatigue life of precision reducers for robots. Background technique [0002] The precision reducer is the core component of the robot, and the service life is an important performance parameter of the precision reducer for the robot. In order to ensure the reliability of the precision reducer used in robots, the fatigue life test of the precision reducer is particularly important. Internal bearing life is the key component that limits the life of precision reducers for robots. The working mode of the precision reducer is frequent acceleration / deceleration and reciprocating swing, and the inertia and impact load on the bearing have a great influence on its life. At present, the existing precision reducer fatigue life test device performs continuous steady-state torque loading on the reducer, which cannot simulate the working condition...
