PLANET GEAR Russian patent published in 2007 - IPC F16H3/44 

Abstract RU 2304732 C2

FIELD: mechanical engineering.

SUBSTANCE: planet gear comprises two driving shafts (O1) and (O2), driven shaft (O3), and four differentials. The first differential comprises outer wheel (9), central wheel (1), and carrier (H1) provided with satellites (5). The second differential comprises outer wheel (10), central wheel (2), and carrier (H2) provided with satellites (6). The third differential comprises central wheel (4), carrier (H3) with two engaged satellites (8) and (7). Two-rim outer wheel (9) is the common wheel for the first and third differentials. Satellite (8) engages the outer wheel. Satellite (7) engages the central wheel and is composed of two spiral gears fit on two axially aligned axles. One of the axles is secured to carrier (H3), and the second axle is connected with central wheel (19) of the fourth differential. The fourth differential has outer wheel (21) and carrier (H4) with satellites (20). Outer wheel (10) is connected with the central wheel (4) by means of gears. Driving shafts (O1) and (O2) are connected with carriers (H1), (H2), and (H3) and outer wheel (21) through pinions (12), (13), (16), and (22). Driven shaft (O3) is connected with central wheels (1) and (2) through pinions (15) and (14).

EFFECT: improved design.
