Embodiment Construction

[0033] The present invention is described in further detail below in conjunction with accompanying drawing:

[0034] see figure 1 , a pairing device for ceramic ball rolling friction test provided by the present invention includes a mounting chuck 2, which is connected to the spindle system 1 of the friction testing machine, and at the same time, the mounting chuck 2 It includes a connecting part and a holding part, wherein the holding part is arranged below the connecting part.

[0035] The connection part adopts a tapered structure, which can be automatically centered with the spindle system 1, and the connection is reliable and the precision is high. The spindle system 1 drives the mounting chuck 2 to perform rotational movement.

[0036] The holding part is a cylindrical structure, and a left cage 3 is installed at the lower center of the cylindrical structure, and one end of the left cage 3 is connected and fixed to the holding part by a hexagon socket head cap screw. ...

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...
