What materials are commonly used to make ball screws?

滚珠丝杠是一种机械元件，常用于传递旋转运动和力矩。它由一个带有螺旋槽的螺杆和一个与之配合的滚珠组成，可以在较小的力矩下实现高效的转动。 而丝母是一种螺纹配件，通常与螺杆配合使用，用于调节和控制螺杆的运动。在滚珠丝杠中，丝母起到与滚珠配合的作用，使滚珠能够在滚动时传递力矩和旋转运动。 支掌座是安装滚珠丝杠和丝母的支架，通常用于支撑滚珠丝杠和丝母，并提供固定和调整位置的功能。它可以根据需要进行调整，以确保滚珠丝杠和丝母的运动和传递效果正常。

以下是一篇关于滚珠丝杠的外文文献： Title: Ball screw drives: Their performance, modeling, and control – A review Authors: Adel A. El-Sharkawy, Mohamed H. Elbestawi Journal: Mechanism and Machine Theory Year: 2003 Abstract: Ball screw drives are widely used in many applications due to their high efficiency, low friction, and high accuracy. This paper provides a comprehensive review of the performance, modeling, and control of ball screw drives. The performance analysis includes the kinematic and dynamic behavior of ball screw drives, as well as the influence of various design parameters on their performance. The modeling section discusses the development of mathematical models for ball screw drives, including both analytical and numerical approaches. The control section presents various control strategies that have been used to improve the performance of ball screw drives, such as position control, velocity control, and force control. The review concludes by discussing some of the current challenges and future research directions in the field of ball screw drives. Keywords: ball screw drives, performance analysis, modeling, control.
