一、Tesla has achieved multiple innovative breakthroughs in the application technology of lead screws in the fields of automobiles and humanoid robots. In the automotive field, the application of ball screws in cars is mainly for steering, parking brakes, service brakes, and other aspects such as seats, sliding doors, and high-end shock absorption systems. REPS uses ball screws and can output a thrust of up to 16KN. Currently, the market's EPB brake calipers mainly use two transmissions: threaded...
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...
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...
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...
