Maximum Permissible Loads and Slip Rates in Metal-Plastic Friction Pairs

摘要

Laboratory test data is given on all-plastics specimen and specimen with a thin layer of plastic to determine permissible combinations of load and slip rates against steel with and without a lubricant. The tests were conducted on a MI-1M friction machine (operated on the principle shaft-partial bearing at slip rates up to 2.0 m/sec., loads up to 80 kg/sq cm and on a disc machine at slip rates up to 10 m/sec., and loads of 100 kg/sq cm. It was shown that out of all materials tested, the heat-resistant polymers - aromatic polyamides with boundary lubrication resulted in the highest permissible service conditions.
