DETERMINATION OF THE PARASITIC FORCES THAT OCCUR AS A CONSEQUENCE OF THE MOVEMENT OF THE ROLLER OVER THE MINIATURE PROFILED GUIDE

Abstract

In order to achieve a greater efficiency degree of electrical, mechanical or other assemblies that work by consuming any form of energy, the frictional force that occurs between all moving elements of the system should be minimized. Nowadays, a lot of standard sliding and rolling pairs have been developed, which provide linear movement. Since manufacturers of these elements do not prescribe coefficient of friction when moving movable rollers on a fixed rail, it is often necessary to know the resistance to motion of these elements due to the correct selection of the drive system, and therefore it is necessary to determine them. In this paper, the resistance to motion of roller through the miniature profile guide 15 mm in width and 10 mm in height was tested.
