What Is The Load On The Ball Screw Pair?

The load on the ball screw pair includes: (1) non-inertial load composed of axial force and preload in assembly; (2) inertial load composed of relative motion rotational angular velocity and gravitational acceleration. The application of the secondary load to the ball screw is divided into 2 load steps: 1. Add the ground gravitational acceleration to the y direction of the entire assembly, and add a preload of 5 MPa to the normal direction of the small end face of the nut, and the direction is along the negative direction of the X axis; ② Keep the above loads unchanged, and at the same time add a working load of 15 MPa to the normal direction of the large end face of the nut, along the mushroom axis; add a rotational acceleration of 5 rad/s to the lead screw. All load application times are 1 s.
