The differences in the application of screw products between domestic new energy vehicles and Tesla vehicles: 一、Application 1. Domestic new energy vehicles: 1) Battery production and assembly: The ball screw assembly is widely used in the winding and stacking processes of cell manufacturing and the module installation of battery packs to ensure the production accuracy and assembly quality of batteries. 2) Body manufacturing: During body welding, ball screws and nuts are used to drive welding...
Fault Diagnosis Methods and Technologies 1. Vibration Analysis Method 1) Vibration signal acquisition Collect the vibration signals of the linear motion ball screw pair through acceleration sensors or displacement sensors. 2) Signal Processing Utilize signal processing techniques such as filtering and envelope to extract information such as fault characteristic frequencies and amplitudes. 3) Fault Diagnosis Based on the characteristics of the vibration signal, determine whether there is a fault...
Ball Screw Troubleshooting Ball Screw Failure Types 1. Wear - related Faults 1) Ball wear The wear on the surface of the balls causes an increase in the clearance of the ball screw and ball nut assemblies, which in turn affects the transmission accuracy and stiffness. 2) Ballnut wear The wear of the internal thread within the nut decreases the contact area with the balls, thus influencing transmission efficiency and lifespan. 3) Raceway wear The wear caused by the rolling of the balls in the...
The ball screw nut pair is greatly used to bear the axial load, radial force, bending moment will make the ball screw nut auxiliary surface contact stress and other loads, which may cause permanent damage to the ball screw. Please note the following points when installing the ballscrew nut assembly into the machine tool: 1) The axis of the ball screw assembly must be parallel to the axis of the matched guide rail. The bearing seat and nut seat at both ends of the machine must be in line at...
