Abstract:
Being capable of predicting the friction torque of micro-type ball screw accurately allows the designer to correctly determine the energy loss and heat generation rate. Since the calculation of traction force is complex and requires much computer time, the forces and moments equilibrium are used for deriving the rolling element-race sliding force. Take into account the influence of spin sliding and helix angle, the final friction torque of micro-type ball screw can be calculated. The micro-type ball screw tests were conducted on a special machine for verification. It is found that good agreement is held between the predictions of the new analytic torque model and the test results obtained with the micro-type ball screw torque rig. Analysis indicates that the performance parameters of lubricant and friction coefficient in ball-races contacts are the main factor to influence the friction torque of micro-type ball screws.
