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...
Analysis of the Causes of Ball Screw Clearance Ball screws are precision components widely used in industrial machinery and equipment, playing a vital role in converting rotary motion into linear motion with high accuracy and efficiency. However, a common problem that affects its performance is the clearance or backlash between the ball nut and the screw shaft. This article will delve into the causes of this backlash. 1. No or insufficient preload Non-preloaded ball screws will slide down when...
