XD-MSM Type Constant Speed Friction Tester
1. The testing machine is mainly used in the friction coefficient and wear rate of the friction material, such as asbestos, powder metallurgy and non-asbestos test.
Execution standard: GB5763-2008 automotive brake linings; GB/T5764-2011 Automotive
Clutch facings; GB/T11834-2011 asbestos friction sheet for industrial machinery; QC/Y227.1-2009 motor test method for friction performance of brake pads for motorcycles and mopeds.
2. Working principle (process) description:
The basic structure and main parameters of the model are specified in GB5763 - 2008.
The AC motor is driven by a vertical shaft with a V belt, and a disc is arranged at the upper end of the shaft. The test piece is clamped on the loading arm, the lever is loaded downwards through the vertical axis, and the load is decided by weight.
