Research output: Contribution to journalArticlepeer-review


The Bulk Temperature Rise Was Studied When A Moving Heat Source With Variable Heat Quantity Was supplied repeatedly at regular intervals on the surface of an isotropic and homegeneous rectangular shaped body used as a model of a spur gear tooth. The effect of radiation at the inner surface of a boss on the bulk temperature rise reduces as the distance between the inner surface of the boss and the working flank is increased. The bulk temperature rise is almost inversely proportional to the interval of the heat supply. The size of the heat supply region and the moving direction of the heat source scarcely affect the bulk temperature rise. In | ῡ | not less than 1000, the bulk temperature rise is not affected by the moving velocity of the heat source, and the approximate bulk temperature rise can be obtained by dividing the temperature rise on the working flank due to the stationary heat source by the number of teeth.
