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...
A ball screw spline is a combination of two components: a ball screw and a rotating ball spline. By integrating the driving element (the ball screw) with the guiding element (the rotating ball spline), the ball screw spline, which is high in rigidity and compact in design, can provide linear and rotational motion, as well as helical movement. ? 1. The main components of a ball screw spline include: ? ? ? 1) Ball Screw In precision machining, a ball screw uses circulating steel balls to drive...
