Research of Slider-crank Massager Noise Fault Diagnosis and Treatment

摘要

The abnormal periodic noise from the slider-crank massager was complained by many consumers when it was under unilateral massage. By anglicizing the worm non-working surface stained with marking compound, the reason of the abnormal periodic noise which stemming from repeated mating of non-normal mating surfaces of the worm gear mechanism is founded. In order to solve the problem the overrunning clutch is used as it's beyond separation functions. When the force is loaded to passive wheel, the clutch is linked; while the load becomes kinetic energy, the power will be separated immediately. The characteristic determines that the overrunning clutch is one of the best choices to separate the load on the slider-crank massager. And the results of the experiment indicate that the method has a significant effect to reduce noise. It also has a practical significance to the common problems of the mechanism and to the related scientific problems.
