Abstract

The axial vibration of precision ball screw mechanism is the major factor on its positioning accuracy and noise. Many factors were contributory to the vibration, which includes the waviness of balls and groove, the friction between moving ball and groove, foreign substance in rollaway nest and the impulse during the balls entering and exiting the return mechanism and etc. In this paper, vibration experiments on pairs of ball screw mechanism which type is CD4020x1200 were performed with different speeds. The test result revealed that the vibration of the mechanism is caused by a periodically invigorative factor varying with rotating speed. Moreover, a few invigorative factors are calculated and analyzed to make sure the driving source. Combining these experiments and the theoretical analysis, it can be concluded that the impulse between the balls and return mechanism mainly causes the axial vibration of the precision ball screw mechanism.
