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...
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 guide rail 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 within the...
The ball screw nut pair is only 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 screw. Correct installation is a prerequisite for effective maintenance. Therefore, the following points should be noted when installing the ballscrew nut assembly into the machine tool: 1) The axis of the screw must be parallel to the axis of the matched guide rail. The bearing seat and...
