2. Cycloidal drive - Wikipedia

   en.wikipedia.org/wiki/Cycloidal_drive

   Cycloidal drive. A cycloidal drive or cycloidal speed reducer is a mechanism for reducing the speed of an input shaft by a certain ratio. Cycloidal speed reducers are capable of relatively high ratios in compact sizes with very low backlash. [1] The input shaft drives an eccentric bearing that in turn drives the cycloidal disc in an eccentric ...

3. Worm drive - Wikipedia

   en.wikipedia.org/wiki/Worm_drive

   A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm wheel (which is similar in appearance to a spur gear). The two elements are also called the worm screw and worm gear. The terminology is often confused by imprecise use of the term worm gear to refer to the worm, the worm wheel, or the ...

4. Reduction drive - Wikipedia

   en.wikipedia.org/wiki/Reduction_drive

   A reduction drive is a mechanical device to shift rotational speed. A planetary reduction drive is a small scale version using ball bearings in an epicyclic arrangement instead of toothed gears. Reduction drives are used in engines of all kinds to increase the amount of torque per revolution of a shaft: the gearbox of any car is a ubiquitous ...

5. Motovario - Wikipedia

   Motovario® was founded in 1965 by Giancarlo Raguzzoni in Formigine in the heart of Modena industrial district. Motovario specializes in the production of mechanical speed variators, helical and helical bevel gear reducers, shaft mounted, worm gear reducers, electric motors and motoinverters.

6. Strain wave gearing - Wikipedia

   en.wikipedia.org/wiki/Strain_Wave_Gearing

   Strain wave gearing (also known as harmonic gearing) is a type of mechanical gear system that uses a flexible spline with external teeth, which is deformed by a rotating elliptical plug to engage with the internal gear teeth of an outer spline. The German company Harmonic Drive SE manufactured the first series-produced gears under the product ...

7. Cycloid gear - Wikipedia

   en.wikipedia.org/wiki/Cycloid_gear

   Cycloid gear. Drawing showing the tooth and leaf profile of a cycloidal wheel and pinion. A cycloidal gear is a toothed gear with a cycloidal profile. Such gears are used in mechanical clocks and watches, rather than the involute gear form used for most other gears. Cycloidal gears have advantages over involute gears in such applications in ...
