Pair matching device used for rolling friction experiment of ceramic ball, and use method thereof

Abstract

The invention provides a pair matching device used for a rolling friction experiment of a ceramic ball, and a use method thereof. A left side retainer, a right side retainer, the ceramic ball, a block test piece and a disk test sample form one group of block-ball-disk pair matching devices, and meanwhile, a distance between the left side retainer and an installation chuck, a distance between the left side retainer and the right side retainer and the length of the block test sample are regulated to meet the clamping of the ceramic balls of different diameters in a certain diameter range. Meanwhile, according to V-shaped grooves arranged on the left side retainer and the right side retainer, an axial dimension is prevented from being regulated. The pair matching device has the characteristics of compact structure, simpleness in operation, stability and reliability in operation and wide applicable range, and has good applicability for researching the tribology behavior of a material under the mixed state of rolling and sliding.

Description

technical field [0001] The invention belongs to the field of material friction, and in particular relates to a pairing device and a use method for ceramic ball rolling friction tests. Background technique [0002] According to the research on the tribological behavior of materials by domestic and foreign scholars, the friction tests of materials are mostly sliding friction and rolling friction. , ball-disk pairing and ring-block matching pair, etc., and most of the matching pairs used to study the rolling tribological properties of materials are four-ball matching pairs, ring-ring matching pairs, and four-ball-rod matching pairs. [0003] For the rolling tribological behavior, it is usually impossible to be pure rolling, mostly rolling and sliding, and there are fewer types of matching pairs. In general, auxiliary test fixtures are required, and especially for ceramic materials, the molding process is more complicated. It is not easy to process into shapes such as rings and...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a pairing device for ceramic ball rolling friction test and its use method, which solves the problem that the size of the auxiliary fixture in the friction test of the existing ball-disc fit is single and cannot meet the clamping requirements for ceramic balls of different size ranges. hold
