摘要

预紧滚珠丝杠传动广泛应用于高精度直线运动，特别是机床进给传动。为了补偿在使用寿命期间因磨损而造成的预紧力损失，并保持典型的工作特性，如零侧隙和高刚性，滚珠丝杠通常预紧到高值。然而，这会导致磨损和摩擦增加，从而导致温度升高。为了解决这些问题，本文介绍了一种新的滚珠丝杠双螺母设计，具有被动预紧调节机制，可以降低预紧水平，同时提高操作特性和操作使用寿命。

Automatic preload adjustment for ball screw drives by means of a spring-loaded mechanism

Preloaded ball screw drives are widely used in high-precision linear motion applications, particularly in machine tool feed drives. To compensate for the loss of preload due to wear over the service life and to maintain typical operational characteristics such as zero backlash and high rigidity, ball screws are usually preloaded to high values. However, this results in increased wear and friction, with a consequent increase in temperature. To address these issues, this paper introduces a novel double nut design for ball screws, featuring a passive preload adjustment mechanism, enabling reduced preload levels while enhancing operating characteristics and operational service life.
