doi:10.3901/JME.2023.03.208

Abstract

Abstract: Up to now, the oversize of rolling elements can only classify the preloading level of linear rolling guides as light, middle, and heavy. Based on the Hertz contact theory, the load and preload drag force model is proposed, firstly. Next, based on a novel measuring system for the load and preload drag force synchronous online measurement, the dynamic friction coefficients of a linear rolling guide (THK-SHS35V) are measured under different load and velocity conditions. And then the Stribeck curve of the linear rolling guide is obtained. Finally, an explicit preload calculation model for linear rolling guides is established by the relationship between the load and preload drag force. The experimental results show that the preload calculation model established in this paper can accurately and effectively predict the preload of the tested sample, with maximum relative error 18.91%. The empirical formula of dynamic friction coefficient obtained by Stribeck curve can be effectively used to establish the preload calculation model of linear rolling guide, which can be further extended to other types of linear rolling guides.

Key words: linear rolling guide, preload, drag force under preload, Stribeck curve, friction coefficient
