| description |
In this thesis, a general model for the tooth meshing of gears is proposed;
in which a quasi-infinite elastic model composed of springs with stiffness
peculiar to the gear is incorporated. Also, the concept of potential gear
noise, which is a noise to express directly the effect of tooth flank form of
gear on the gear noise, is proposed and a sensory evaluation method is
also proposed to evaluate sound level, noise quality and noise. The
influence of tooth flank form deviation on transmission error is further
investigated by using this model. The qualitative characteristic of the
transmission error of gears with convex tooth flank form deviation is
determined by the actual contact ratio and qualitative elements of gears;
i.e. tooth flank form deviation and the distribution of stiffness. It can be
concluded that the proposed sensory evaluation method of potential gear
noise could enable gear designers to experience directly the effect of
tooth flank form on the noise quality |
