The invention relates to a
testbed for the reliability of a
power unit of an
industrial robot and belongs to reliability testing devices. The
testbed is composed of a
tris-comprehensive test box, the
power unit, a radial force loading unit, a
universal joint coupler and a torque loading unit. The
power unit and the radial force loading unit are placed in the
tris-comprehensive test box, and the torque loading unit is connected with the power unit through the
universal joint coupler. The actual working condition of the power unit of the
industrial robot can be simulated for reliability testing, the power unit is located in the
tris-comprehensive test box, applying of loads such as the temperature,
humidity and vibration of the power unit can be achieved, therefore, the actual environment working condition of the power unit of the
industrial robot is simulated, higher testing efficiency is achieved, the
automation degree is high, vibration, temperature, transmission efficiency, power losses and other parameters of the power unit can be acquired and calculated in real time, and the
testbed can be used for detection of
transmission errors, return differences and backlashes of a speed
reducer.
