An analytical theory of gear turning — gear skiving for internal gears and gear generating for external gears

International Journal of Machine Tool Design and Research, 1982
Abstract Gear turning, i.e. gear skiving for internal gears and gear generating for external gears, is a new high productive method to produce both internal and external, spur and helical gears and cylindrical worms using a rotating tool. The gear turning cutter is a pinion-type shaper.

Gears and gearing

1994
Gears (or gear wheels) are toothed wheels which are usually used to couple two or more rotating shafts. The shafts may be rotating at the same speed or at different speeds, and can have axes which are pointing in the same direction or in different directions The ratio of the speeds of rotation of two shafts coupled by gear wheels, depends on the ratio ...

Gear Trains and Planetary Gears

2020
In this chapter, the general concepts of ordinary gear trains are first described, particularly those concerning their efficiency and the obtainable transmission ratios. The same concepts are then extended to planetary gear trains and various methods of calculating the transmissions ratios achievable with these types of gear drives are defined.
