As a basis for the study to clarify the relationship between scoring occurrence and temperature in spur gear pairs, the temperature rise in a rectangular shaped body used as a model of a gear tooth was examined analytically, when a moving heat source with variable heat quantity was supplied repeatedly at regular intervals. The characteristic of the temperature rise of the body and the effect of radiation on the temperature rise were investigated. The temperature rise on the working tooth flank in the heat supply region and its neighborhood can be divided into the flash temperature component not affected by the state of radiation and the bulk temperature rise component significantly affected by it.
