In the first report, the .method of calculating the fatigue strength of plastic gears using strain energy was proposed; however, the conditions only extended to gear life in the normal temperature environment. Recently, the use of plastic gears has expanded, so that they are used frequently in elevated temperature environments. For example, the plastic gears used to drive the drying drum of a paper-making machine perform at the ambient temperature of about 90℃. Owing to these facts, the method of estimating the operation life of plastic gears is proposed in this report. Here, the change of the properties of teeth due to temperature difference was taken into account using the calculation method from the previous report in order to determine the type of teeth which can cope with the plastic gears in the environment of both elevated temperature and normal temperature.
