Example Embodiment
[0013] The invention adopts the loading method of fixing the screw under test and exerting force on the nut under test, and uses the pressure sensor and the displacement sensor to sample the axial load and the axial micro-displacement of the nut under test, wherein the pressure sensor is fixed with the nut under test. The displacement sensor is installed on the bed through the displacement sensor fixture to measure the vertical displacement of the right end face of the tested nut. By processing the sampled data, the axial static stiffness curve of the ball screw pair under tension and compression can be drawn respectively, and the value of its value can be finally calculated, so as to realize the measurement of the axial static stiffness of the ball screw pair. The details are as follows.
[0014] combine figure 1 , the ball screw pair axial static stiffness horizontal measuring device of the present invention includes a loading assembly, an anti-rotation assembly, a measuring...
