Chinese invention patents with patent numbers 201010039688.6 and 201010101178.7 disclose the axial loading structure of the ball screw pair, but because it uses a hydraulic system to provide axial force, the piston rod is fixedly connected to the ball nut, which greatly weakens the vibration of the ball screw pair Signal

Description

technical field [0001] The invention relates to a loaded ball screw pair failure test test bench. Background technique [0002] The fault of the ball screw pair will seriously affect the axial positioning of the CNC machine tool. At present, the research on the performance of the ball screw pair is relatively comprehensive in China, but the research on the fault of the ball screw pair is insufficient. Aiming at the deficiencies in the design of the fault experiment of the ball screw pair, a ball screw fault test bench is designed to facilitate the collection of fault vibration signals. [0003] In order to test the vibration signal of the ball screw pair under the action of axial force, an axial load is applied to the ball screw pair. Chinese invention patents with patent numbers 201010039688.6 and 201010101178.7 disclose the axial loading structure of the ball screw pair, but because it uses a hydraulic system to provide axial force, the piston rod is fixedly c...
