CALCULATION OF DURABILITY OF CYLINDRICAL METAL-POLYMER STEEL - EPOXY COMPOSITE DK-6 SLIDING GUIDE

Abstract

According to the developed method of calculating the resource of cylindrical metal-polymer sliding guides, the resource of the guide at different loads and radial clearances is performed. The method is based on the known methodology for studying the kinetics of wear of materials during sliding friction. The slider of the guide is made of antifriction polymeric epoxy composite material DK6 of high hardness, and its base is made of steel. Quantitative and qualitative regularities of dependence of friction path on load and radial clearance are established. It is shown that increasing the load four times causes a decrease in the friction path by 5.61… 9.20 times, depending on the radial clearance ε and the diameter of the base. And doubling the radial clearance causes a decrease in the friction path by 2.40… 3.40 times depending on the load and the diameter of the base.
