2. Reduction drive - Wikipedia

   en.wikipedia.org/wiki/Reduction_drive

   The Midwest twin-rotor wankel engine has an eccentric shaft that spins up to 7,800 rpm, so a 2.96:1 reduction gear is used. Aero-engine reduction gears are typically of the gear type, but smaller two-stroke engines such as the Rotax 582 use belt drive with toothed belts, which is a cheap and lightweight option with built-in damping of power surges.

3. Cycloidal drive - Wikipedia

   en.wikipedia.org/wiki/Cycloidal_drive

   The reduction rate of the cycloidal drive is obtained from the following formula, where P means the number of the ring gear pins and L is the number of lobes on the cycloidal disc. = Single-stage efficiency approaches 93% and double-stage approaches 86%. [3]

4. Propeller speed reduction unit - Wikipedia

   en.wikipedia.org/wiki/Propeller_Speed_Reduction_Unit

   The propeller speed reduction unit of a Rolls-Royce R engine. A propeller speed reduction unit is a gearbox or a belt and pulley device used to reduce the output revolutions per minute (rpm) from the higher input rpm of the powerplant. [1]

5. Briggs & Stratton - Wikipedia

   en.wikipedia.org/wiki/Briggs_&_Stratton

   gear reduction (gears bolted to the back of the engine to slow the speed of the PTO shaft) first offered in 1934, on models A B K and Z later on I U N and WI. Designated by an "R" after the basic model, then a 2, 4, or 6 to designate the reduction ratio.

6. Pneumatic motor - Wikipedia

   en.wikipedia.org/wiki/Pneumatic_motor

   Because the engine flywheel requires a great deal of torque to start the engine, reduction gears are used. Reduction gears create high torque levels with the lower amounts of energy input. These reduction gears allow for sufficient torque to be generated by the engine flywheel while it is engaged by the pinion gear of the air motor or air starter.

7. Worm drive - Wikipedia

   en.wikipedia.org/wiki/Worm_drive

   Therefore, regardless of the worm's size (sensible engineering limits notwithstanding), the gear ratio is the "size of the worm wheel - to - 1". Given a single-start worm, a 20-tooth worm wheel reduces the speed by the ratio of 20:1. With spur gears, a gear of 12 teeth must match with a 240-tooth gear to achieve the same 20:1 ratio.
