Planetary Gearing

Primary Gearing (Back Gears) For The Grizzly 9x20 Lathe
Detailed information on planetary gearing may be found in Machinery’s Handbook. (Number 26, Pg 2084). Use of planetary (or epicyclic) gearing provides a means of obtaining a compact design of power transmission, with driving and driven shafts in line, and a fairly high ratio of reduction.

Dual Speed Focuser - Wikipedia
Dual speed focuser design borrows the planetary gearing idea used in automobile gearboxes. However, in order to eliminate backlash, balls and axles are used instead of gears. All the transmission inside a dual speed focuser is achieved via static friction. The cylinder case of a dual speed focuser is fixed on the telescope tube. ... Read Article
