During World War II, a special variation of epicyclic gearing was developed for portable radar gear, where a very high reduction ratio in a small package was needed.

While speed reduction ratio is 1 : 3.17, wheel diameter is, and electric engine clamp voltage is 1500 volts, ER1 and ER2 electric trainsets have following traction data:
23.
Even if the cost is higher per cm2, the overall cost of a system may be lower as the concentration ratio equals the reduction ratio for the CPV material.
24.
Power was transmitted from each engine by a torsion shaft which was engaged through a series of sun, planet, epicyclic and spur gears to give a suitable reduction ratio and correct propeller-shaft rotation.
25.
The engine is a single rotor four-stroke, air and liquid-cooled, gasoline Wankel engine design, with a mechanical gearbox reduction drive employing a helical gear set with a reduction ratio of 3.225 : 1.
26.
For example, if there are 202 teeth on the circular spline and 200 on the flex spline, the reduction ratio is ( 200 & minus; 202 ) / 200 = & minus; 0.01
27.
The MZ 201 has a choice of a reduction drive belt or gearbox, while the MZ 202 offers just the gearbox with reduction ratios of 2.18, 2.55, 2.88, 3.11 or 3.66 to 1.
28.
The GO-145 is a geared model, introduced in 1938, that uses a 27 : 17 reduction ratio ( 1.59 : 1 ) gearbox to produce at 3200 crankshaft rpm, giving 2013 propeller rpm.

It has a primary reduction ratio of : 4.058, and a secondary reduction ratio of 2.6 via the chain drive ( 15 tooth front sprocket and 39 tooth rear sprocket ) . [ 1]
