PLANETARY GEAR Russian patent published in 2016 - IPC F16H1/48 

FIELD: machine building.

SUBSTANCE: invention is intended for use in different mechanisms in car, motorcycles and bicycles transmissions, automatic gearboxes, etc. Planetary gear consists of central wheel, pinion and carrier coupled by geometrically closed eccentric coupling made with possibility of pinions locking. Locking of pinion is provided by displacement of carrier relative to pinion in circumferential or tangential directions, wherein displacement value of carrier relative to pinion at number of fixed pinions of more than one can be identical or different. Locking of pinion is performed at speed lower than speed of carrier rotation. Eccentric coupling can be made in form of eccentrically located extending section of outer surface, or pinion, or carrier which is interfaced with hole or slot made on carrier or pinion or in form of eccentric element having eccentrically arranged extending sections. Extending section of eccentric communication may be made in form of one rolling body.

EFFECT: higher service life of planetary gear.
