Abstract

The invention discloses a friction test device, which belongs to the technical field of friction and wear testing. The device includes a friction pin, a friction disc, a friction disc drive unit, a cam, a cam drive unit, a retractable component, a box body and a support frame, the first end surface of the friction pin is in contact with the non-center area of ​​the friction disc, and the center area of ​​the friction disc is in contact with the The friction disk driving unit is mechanically connected; the friction disk driving unit is used to drive the friction disk to rotate, so that the friction disk and the friction pin slide relatively; It is mechanically connected with the cam drive unit; the cam drive unit is used to drive the cam to rotate, so that each area of ​​the surface of the cam is in contact with the telescopic part in turn; the box is sleeved outside the telescopic part and the friction pin, and the box is fixed on the support frame Above; the box is used to keep the telescoping part stationary when the cam rotates and the friction pin to remain stationary when the friction disc rotates. The invention can improve test accuracy.

Description

technical field [0001] The invention relates to the technical field of friction and wear testing, in particular to a friction testing device. Background technique [0002] A friction pair is a system composed of two objects that are in direct contact and produce relative frictional motion. According to the motion form of friction pair, it can be divided into sliding friction pair and rolling friction pair. The surfaces of two objects in a sliding friction pair have relative sliding or relative sliding tendency. For example, there is mutual sliding between the piston ring and the cylinder liner in the marine engine parts, and the two form a pair of sliding friction pairs. [0003] The interacting surfaces of marine engine parts are subject to wear due to (sliding) friction. Generally, parts that fail due to wear and tear account for 80% of all scrapped parts. Therefore, to ensure the normal operation of marine engine parts, it is very important to accurately evaluate the ...
