The contents of the second edition of the book have been thoroughly revised and substantially augmented in comparison with the first edition of 1994.

New topics in the second edition include the following new developments:

1. A new geometry of modified spur gears, helical gears with parallel and crossed axes, a new version of Novikov–Wildhaber helical gears, a new geometry of face-gear drives, geometry of cycloidal pumps, a new approach for design of one-stage planetary gear trains with improved conditions of load distribution, and a new approach for design of spiral bevel gear drives with a reduced level of noise and vibration and improved bearing contact.

2. Development of an enhanced approach for stress analysis of gear drives by application of the finite element method. The advantage of the developed approach is the analytical design of the contacting model based on the analytical representation of the gear tooth surfaces.

3. Development of a new method of grinding of face-gear drives, new methods of generation of double-crowned pinions for localization of the bearing contact and reduction of transmission errors, and application of modified roll for reduction of transmission errors.

4. Broad application of simulation of meshing and tooth contact analysis (TCA) for determination of the influence of errors of alignment on transmission errors and shift of the bearing contact. This approach has been applied for almost all types of gear drives discussed in the book.
