Abstract　In this paper, the authors researched the equilibrum temperature in the teeth of plastic gears which should be taken into consideraration on the design of plastic gears. There are two kinds of heat that can be generated by meshing the of plastic gears : first, the frictional heat, produced by the friction between teeth's surfaces : and secondly, the heat, derived from the hysteresis loss due to the fact that plastic material is viscoelastic. Also, regarding the quantity of heat, which is emitted into the atmosphere from the higher-temperature tooth surface of rotating gears, the authors derived a calculation formula based on their experiments, and from these, they were able to obtain another calculation formula of determing the equilibrium temperature in the teeth of operating plastic gears. The equilibrium temperature in the teeth of test gears were also experimentally measured and these measured values were compared with the calculation values : both showed comparatively good coincidence.
