 note = {Until now, the decrease of mechanical strength owing to temperature rising is attached great importance as the most important factor to decide the life cycle (wear, breakage) of plastic gears for power transmisson. But, there is few example that tooth flank temperature is actualy measured. Also, the relation between tooth flank temperature and tooth damage is not examined enough. In this report, tooth flank temperature of plastic gears is measured in detail by usig a radiation pyrometer and the results are obtained as follows: 1. When module is large, average temperature of working flank is high and that the difference of maximum and minimum temperature is large. 2. Pitch point does not always take maximum temperature, there are some cases in which tooth flank temperature is influenced by the interference by teeth of steel gears. 3. Cooling effect of teeth by rotation is affected by gear operating position (driver or follower) and combination of gear materials. 4. It is very effective for preventing temperature rising to cool forcibly the tooth of plastic gears. So, if forced cooling is applied, extention of life cycle can be expected. 5. Breakage point of plastic gear teeth does not always coincide with maximum temperature point., 長崎大学工学部研究報告, 21(37), pp.125-132; 1991},
