The effect of the stressed state of the ring gear due to interference with the base part in calculating the flexural strength of the tooth

Strain intensity state (SIS) of a non-rigid toothing in which the shape of the hole is distorted during the clean-working stage due to elastic deformations from clamping forces of the self-centering chuck in research by photomechanics method. For this reason, when the toothing is placed on the base part with interference, there is uneven pressure on the contour of its hole, and also a preliminary uneven SIS is formed in the transitional fillets of the interdental space, which reduces the service life of the toothing by flexural strains. © Published under licence by IOP Publishing Ltd.
