In the present paper, by using rate of load distribution of tooth and the same loaded condition as that in the dynamic condition, stresses and deformations of teeth and rim of spur gears with a thin rim were calculated, and the calculated results (by the finite element method) were compared with the experimental ones. Moreover, accuracy deterioration of spur gears with a thin rim was discussed. The following conclusions were obtained. (1) From the results of the present study, the stresses at the root fillet of tooth of spur gears with a thin rim and solid gears, their deformations under dynamic condition and the degree of accuracy deterioration of those spur gears when rate of load distribution was considered were clarified. (2) It was found that lag of a tooth intermeshed with No. 1 tooth corresponding to the spoke is maximum.
