The present paper describes a fast method for obtaining the bending of spiral bevel gears teeth. The method is functionbased
for greater speed, these functions being determined from only one FEM calculations in order to remain general.
It was shown that this method is as precise as the FEM method, with the advantage that it is much faster, as fewer FEM
calculations have to be carried out.
These functions were integrated in the calculation process to compute the instantaneous load sharing of the spiral bevel
gears. Computation time takes about ten hours without interpolation functions, whereas only 1 h is necessary to obtain similar
results with interpolation functions.
Another advantage of the method is that the surrounding of the gear can be taken into account. In the FEM computations,
global element or special geometry like: shaft shape, bearing location, small rim or web arrangements ... can be integrated in
the computation procedure and can influence all the results (load sharing, instantaneous pressure, stiffness, transmission
error. . .).
