ORBIT REDUCTION GEARBOS (VERSIONS) Russian patent published in 2008 - IPC F16H1/32 

FIELD: engines and pumps.

SUBSTANCE: invention relates to machine building particularly to the reduction gearbox with coaxial drive and driven shafts. The orbit reduction gearbox incorporates housing accommodating high-speed and low-speed shafts (4, 5). A set roller (13) is fitted in appropriate holes arranged along the edges of side the housing cover (3). The plate (11) accommodates rollers (12) arranged regularly along the edges with the center on axis (8) of low-speed shaft (5). A link representing plate (9) and rollers (10) and coupling rollers (12, 13) is fitted onto pin (7). With the high-speed shaft (4) running plate (9) effects orbital motion. Since rollers (10) are engaged with rollers (12, 13) shaft (5) revolves. The gear ratio i of this reduction gearbox can vary from 3.5:1 to 3000:1. to change i in the aforesaid limits, it is required to change the number of rollers in plates (9, 11) and in the housing cover (3).

EFFECT: toothed reduction gearbox with no gear wheels but with higher reliability and simpler design.
