A Study on Strength Design Methods for Plastic Gears : Estimation of Operation Life of Plastic Gears Elevated-Temperature Environment

概要

論文の詳細を見る
In the previous 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 ordinary-temperature environment. Recently, the use of plastic gears has expanded, so that they are now used frequently in elevated-temperature environments. For example, the plastic gears used to drive the drying drum in paper-making machines perform at the ambient temperature of about 90℃. Owing to these facts, a method of estimating the operation life of plastic gears is proposed in this report. Here, the change of the properties of teeth due to working temperature was taken into account using the calculation method developed in the previous report in order to be able to cope with the plastic gears operated in the environment of both elevated-temperature and ordinary-temperature.
