A conceptual design of an innovative test rig for endurance tests of ball screws is presented in this paper.The test rig layout is based on the power recirculating principle and it also allows to overtake the main critical issues of the ball screw endurance tests.Among these there are the high Bone Support Formulas power required to make the test, the lengthy duration of the same and the high loads between the screw and the frame that holds it.The article describes the test rig designed scheme, the kinematic expedients to be adopted in order to obtain the required performance and functionality and the sizing procedure Dishwasher Escutcheon Panel to choose the actuation system.
