Vibration of Rail Type Rolling Guides with Recirculating Balls (1st Report, Vibration of Rolling Guide Driven at a Constant Velocity)

摘要

The vibration of rail type rolling guides with recirculating balls was studied. The test rolling guides were operated at a constant linear velocity and the vibration of a rolling guide itself was measured. In addition, an experimental modal analysis was performed on the bearing block of a rolling guide under a constant linear velocity. Experimental results showed that the main peaks appear in the vibration spectra is not affected significantly by the linear velocity and the occurrence of the main peaks is influenced by the preload and the vibration measurement point. Analysis indicates that the main peaks are caused by the lower rolling natural vibration, the higher rolling natural vibration, the yawing natural vibration, the pitching natural vibration, the vertical natural vibration, the first flexural natural vibration, the second flexural natural vibration, the third flexural natural vibration of the bearing block.
