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...
Failure Prevention and Maintenance of Ball Screw Sets 1. Regular inspection and maintenance 1) Check the wear condition of the ball screw pair The entire wear inspection encompasses the balls, screw shaft, and nuts. Severely worn components should be replaced promptly. 2) Check the straightness and curvature of the screw shaft Ensure that the straightness and curvature of the ballscrew shaft are within the allowable range to prevent the accuracy from being affected due to deformation. 3)...
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...
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...
