プラスチック歯車の歯車本体の肉厚に関する一考察

In the case of cast gears, the dimensions of various parts of gear bodies are mostly designed on the basis of empirical data. However, for plastic gears, such empirical design data are few: accordingly, even though the indicated transmitting power is the same, large difference is observed in the thickness of gear bodies and others among different to manufacturers. Therefore, in this study, as one procedure of examining the effect of the difference in the thickness of gear bodies such as these on the operation of the plastic gears for transmitting power, operation tests were carried out by using various thicknesses of disks and of rims in disk type plastic gears, and the relationships of the change of these thickness with the life, wear, change of tooth profile and the other characteristics of plastic gears were examined.
