The effect of the rise in tooth temperature on tooth bending strength is not considered in the calculation of load capacity of plastic gears. The tooth temperature of a plastic gear greatly rise with the rise of heat due to tooth flank friction and hysteresis. However, calculation of tooth bending strength of a plastic gear does not include the effect. In the present paper, the temperature-rise factor is discussed. It will be incorporated in calculation of tooth bending strength of a plastic gear to include the effect. Three-dimensional analyses of heat generation and conduction in plastic gear pair were performed using a developed computer program, and the calculated tooth flank temperatures were compared with measured ones obtained from experiments with POM gears with various facewidths. The temperature-rise factor was proposed in basis of these calculated and measured tooth temperature and thermal behavior of the allowable bending strength of the material.
