BALL EPICYCLIC FRICTION GEARS

Category of development 
Mechanical engineering
The essence of development. Purpose and scope 

The structure is based on two or three standard spherical ball bearings consequently composed and acting as epicyclic gears.The R&D product is destined to be applied as a reducing gear, multiplying gear and a gear shift transmission with capacity of up to 0.5 kW and a gear ratio from 2.5 to 15.

The main advantages 

High technological effectiveness in comparison with the tooth gearings, compactness and small size, overload protection, alignment of the structure, noiseless operation, on-the go shifting.

The degree of readiness. Protection of intellectual property 

There have been developed operating pilot units of a transmission gear, reducing gears and multiplying gears, and field research has been carried out.The structure developed is covered by three Ukrainian patents.
