In the present paper we describe the results of theoretical and experimental studies on the load distribution of non-metallic gear teeth.
The measurement of load distribution is carried out with method in which the strain on root fillet in the case of slow rotation of the gears is compared with the strain in the case of full loading on one tooth, and the measurement of strain on root fillet is carried out by the electric resistance strain gauges stuck there.
The result of theoretical study shows good coincidence with the result of experimental study.
As a result of this study we find that tooth profile correction is necessary to get good load distribution when metalic gear is meshed with non-metalic gear.
The value of correction is found easily with the method adopted in the present paper.
