REVERSE REDUCTION GEAR Russian patent published in 2008 - IPC F16H3/60 

FIELD: mechanics.

SUBSTANCE: invention relates to mechanical gear transmission to transfer the torque at a time with reversing and may be used transport machine building, in particular, in marine power plant reduction gears. The reversing reduction gear incorporates a coaxial input (1) and output (2) shafts with respective input (3) and output (4) planetary cylindrical gears and a reversing planetary transmission gear (7) with bevel gears. The transmission gears are consecutively coupled by two coaxial shafts, i.e. internal (10) and outer shaft formed by coaxial half-axles (8, 9) of the reversing gear central wheels. The coaxial shafts are arranged coaxially with the input and output shafts and provided with the clutches. One of the clutches is a three-position device arranged so as to provide for meshing of inner shaft (10) and half-axle (8) of the driving cylindrical wheel with carrier (17) of the input transmission. Another one, a two-position input transmission gear, is arranged in the housing of carrier (6) of output transmission gear to allows meshing of inner shaft (10) and half-axle (9) of the reversing gear driven shaft. The reducer features perfected operating performances and boasts lower costs and smaller weight and overall sizes, plus higher reliability.

EFFECT: improved operating performances, lower costs and higher efficiency and reliability.
