A computer program based on finite elements has been used for the calculation of displacements in the worm and the gear of a cylindrical worm gear drive with concave worm profile, ground by a grinding wheel of double arc profile. The influence of the design parameters of the worm gear drive and of the load position on displacements has been investigated. On the basis of the obtained results, by using regression analysis and interpolation functions, equations for an easy calculation of displacements in the worm thread and in the gear tooth have been derived.
