Problems solved by technology

However, there is no related rolling friction pair used in friction and wear tests, which means that the actual working conditions of the rolling friction pair cannot be simulated, which seriously hinders more in-depth research on the rolling friction pair.

Embodiment Construction

[0028] The present invention will be described in further detail below.

[0029] A rolling friction pair used for friction and wear tests, comprising: a bearing shaft 1, an upper pressing plate 2, a roller 3, a fastening chuck 4, and a roller disk 5. Wherein, the upper end of the bearing shaft 1 is fixedly connected with the load applying part of the friction and wear testing machine, the bearing shaft 1 is in clearance fit with the blind hole 2-2 of the upper platen 2, and the two are fixed together by the screw through the screw hole 2-1 At the same time, the fastening screw passes through the screw hole 2-3 to ensure that the two do not rotate relative to each other, and the load applied by the friction and wear testing machine can be transmitted to the upper platen 2 through the bearing shaft 1. The screw completely fixes the fastening chuck 4 and the rotating spindle chassis of the friction testing machine through the screw hole 4-2, and the fastening chuck 4 can obtain a...

Abstract

The invention relates to a rolling friction pair used for friction-wear test and a test method thereof. The rolling friction pair comprises a force bearing shaft, an upper pressing plate, rollers, a fastening chuck and a roller plate, wherein the upper end of the force bearing shaft is connected with a load applying part of a friction-wear testing machine, and the lower end of the force bearing shaft is connected with the upper pressing plate; the lower end of the fastening chuck is connected with a rotary spindle chassis of the friction-wear testing machine, the roller plate is fixed in the fastening chuck with an opening at the upper end, and the rollers are arranged in a tooth space of the roller plate; in testing, the lower end face of the upper pressing plate tightly presses a busbarat the upper ends of the rollers, the rotary spindle chassis of the friction-wear testing machine drives the fastening chuck and the roller plate to perform autorotation, and the rollers rotate circumferentially along with the roller plate and performs autorotation. The rolling friction pair fills up the blank that no rolling fiction pair is applied to friction-wear test, and is simple in part structure and high in reliability; the rolling friction pair can be efficiently embedded into most existing friction-wear testing machines, and an embedding method is simple and convenient and easy to operation; and the rolling friction pair belongs to the technical field of friction pairs.

Description

technical field [0001] The invention relates to a friction pair for a test, in particular to a rolling friction pair used for a friction and wear test and a test method thereof. Background technique [0002] The relative movement of mechanical parts in contact with each other causes friction and wear, which is one of the important reasons for the sudden drop in the reliability of the mechanical control system and the precision retention of precision instruments. The friction and wear testing machine is a scientific equipment to study the friction and wear and lubrication performance of the contact surface. It simulates the actual working environment of the workpiece through a simplified model to obtain relevant friction and wear data, so as to obtain feedback to improve the performance of the friction pair. At present, friction and wear testing machines are widely used to study point-surface, line-surface, surface-surface sliding friction. However, the key positions of some...
