COAXIAL REDUCTION GEAR Russian patent published in 2014 - IPC F16H1/32 F04B47/02 F04C2/107 

FIELD: transport.

SUBSTANCE: coaxial reduction gear consists of driving cam shaft (5), crown gear, output shaft. Crown gear has double wheel (2). Coaxial to cam shaft gear (1) is connected with body and conjugated with crown (2) of double wheel from the side of driving cam shaft. Gear clutch providing coaxiality of driving cam shaft (5) and output shaft is connected with output shaft and conjugated with crown(3) of double wheel from the side of output shaft. Pitch surfaces (planes) of crown gears (2, 3) of double wheel are located along its axis at a distance providing coincidence of gear clutch pitch cone vertex with point of intersection of cam shaft axis and coaxial reducing gear axis. Module and number of teeth of gear clutch are taken to be equal, greater or less than module and number of teeth of crown gear.

EFFECT: invention provides high loading capacity, durability and makes possible to considerably lower required engine power without decreasing torque output shaft of reduction gear.
