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.,
4. 安装不稳定或调整不当,导致晃动,滚珠丝杠轴承支承方式有以下几种:
1. 固定支承:滚珠丝杠轴承的两端通过固定端盖或定位销等固定在机床床身或其他支架上,用于固定滚珠丝杠轴承的位置和方向,
2. 油盒内的润滑油通过一个小孔流入到滚珠丝杠的内部,形成一层润滑膜,降低滚珠丝杠的摩擦系数,减少能量损失,不过,由于滚珠丝杠螺母副需要经常进行润滑和维护,因此在使用过程中需要注意保养和保养周期的确定,
2. 滚珠丝杠表面磨损严重,导致表面发黑,
2. 然后,使用一个力量计或扭矩扳手来测量螺母的预紧力,但是在某些特殊情况下,例如Fm长度较长或者负载较大时,为了保证Fm的稳定性和精度,可以考虑采取一些固定措施,例如增加支撑点、加装支撑架等,
2. 安装滚珠丝杠时,应注意其方向和位置,确保其正确安装
