Abstract:

In order to obtain the amplitudes of different meshing transfer points and the minimum fluctuation of thetransmission error under a given predesigned contact ratio and applied load,a design method of the fourth- ordertransmission error is proposed for the spiral bevel gears being cut via the modified roll method on the pinion. In theinvestigation,a symmetrical design of meshing position with predesigned contact ratio of spiral bevel gears isachieved by adjusting the direction of the contact path and the location of the reference point. Then,a high- orderdegeneration coefficient is deduced by means of the anti- TCA (Tooth Contact Analysis) method with a pre- designedexpression of the fourth- order transmission error.Numerical results show that the fourth- order transmission errorswith different amplitudes of meshing transfer points can be obtained by adjusting the former four coefficients of thepolynomial,which affects the fluctuation of the loaded transmission error and the corresponding applied load; andthat the fourth- order transmission error is controlled by the ease- off of the pinion surface.
