抄録: In order to examine the feasibility of engineering plastic gears as an element of power transmission, unsteady temperature variations in a plastic gear owing to the periodically induced heat on the contacting surface are simulated by means of the explicit finite difference method. In the current study, the involute geometry of the gear tooth is simplified by two sizes of rectangular blocks and the repeatedly induced heat on the tooth is treated by the equivalent fixed constant temperature at the contact region around the pitch circle during the contacting time. Numerical results obtained by the current two-and three-dimensional models are summarized as follows: (1) After the long operation time, the heat balance between the input and output during its rotation period is attained, which gives a steady temperature profile at the same time of the period. (2) The temperature distribution obtained by 3-D model is lower than that by 2-D model for the same operating condition since the heat release of both end faces to the air is taken into account. (3) As the heat transfer coefficient from the surfaces of a gear to the air increases, the rise of temperature inside the gear is suppressed. (4) The experimental result which has the asymmetrical profile of surface tempeJature may be explained by the partial contact of gears.
