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...
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...
Ball screw by the screw, nut, steel ball, reverse device, or dust collector composition, is the most commonly used transmission mechanism for tool machinery and precision machinery. Its main function is to convert the rotary motion into linear motion or convert the torque into axial recurrent force, with high precision, reversibility, and high-efficiency characteristics. Due to its small frictional resistance, the linear motion ball screw is widely used in a variety of industrial equipment and...
