The Gearing Temperature Shock Oscillation

摘要

The article describes the temperature oscillation caused by shock mechanical parameters changing. The special effort on the heating curve parameters is put. The shock changes of the mechanical parameters (change of floating power) cause the extremely fast temperatures changes ongoing on the teeth flanks. The gear oil can be damaged during these processes. The lubrication parameters are changing and mechanical failures can be caused too. The automobile MQ100 gearbox for the measurements was used. The unique equipment for the temperature measurement was applied. The special stand for the operation of the gearbox was used. The gearbox operation condition was similar as in passenger car operation, without other heat sources (as a combustion engine) only. This short article describes the automobile gearbox final drive pinion teeth temperature measurements during the shock power float parameters changing. The aim of the article is a description of the tooth heating curve parameters. The goal is the maximal temperature gradient computing.
