    摘要： An accelerated life test method for a speed reducer of an industrial robot is provided. The accelerated life test method includes: setting first load stress higher than rated load stress and second load stress lower than the rated load stress; performing an accelerated life test by loading the first load stress to first speed reducer samples; calculating a service life of each of the first speed samples in the accelerated life test; performing a contrast test by loading the second load stress to second speed reducer samples; calculating a service life of each of the second speed samples in the contrast test; and calculating an acceleration coefficient, and the acceleration coefficient is equal to a ratio of the service life in the accelerated life test to the service life in the contrast test.

    摘要： A flexspline protective structure includes a first rotation member, a second rotation member and a plurality of fixing members. The second rotation member is sleeved on the first rotation member. The plurality of fixing members fix the first rotation member and the second rotation member together and are capable of breaking off in the event of jamming or other mischance to enable the second rotation member to rotate freely relative to the first rotation member. The disclosure presents a robot arm mechanism equipped with the flexspline protective structure.
