Description

Technical Field

[0001] The invention relates to the technical field of industrial robot reducers, and in particular to a transmission efficiency test bench for industrial robot reducers. Background Art

[0002] The power unit of an industrial robot is mainly composed of a servo motor and a reducer, and its cost accounts for more than 65% of the total cost of the whole machine. As the core component of the robot, its accuracy and reliability are crucial. The servo motor of the power unit of an industrial robot has the characteristics of small inertia, fast response speed, and low maintenance and servicing requirements; the reducer of the power unit of an industrial robot is one of the key technologies of an industrial robot.

[0003] Some industrial robot power unit reducer performance test benches generally use the "input motor, torque or speed sensor, reducer, torque or speed sensor, magnetic powder brake" structure, which is only suitable for reducer performance parameter testing and cannot be used for reliability testing. It is more efficient to conduct reliability testing on the power unit of an industrial robot as a whole than to test the reducer and servo motor of the power unit separately, and it can more conveniently simulate actual working conditions.

[0004] When testing the transmission efficiency of the reducer, since the reducer is installed with bolts, the bolts and nuts will loosen and vibrate when the reducer rotates for a long time, which will lead to a loose connection between the reducer and the test bench, resulting in large fluctuations in the measured value, large errors in the calculated transmission efficiency, and failure to accurately reflect the true performance of the reducer.
