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...
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...
We can implement effective measures to prevent damage to the guideway. 1. The machine tool guideway should have sufficient and reasonable lubrication conditions. ? Good lubrication conditions to reduce the damage to the?industrial drawer slides?are essential. When the relative movement between the guide surface filled with lubricant, the formation of oil film, the establishment of the liquid friction between the guide surface does not occur direct friction, which occurs between the molecules...
