GEAR REDUCER Russian patent published in 2014 - IPC F16H1/48 

FIELD: machine building.

SUBSTANCE: invention relates to small-sized special drive mechanisms with high gear ratio, high torque on the output shaft and can be used as drives for solar cell panels, antennas and bars of special spacecraft equipment, in aircraft engineering and ship building of planning boats, as well as in machine tool building at producing drives for CNC machines, robotic complexes and high-torque hand electric tools. A gear reducer comprises gear transmissions and input (3), intermediate (5) and output (7) shafts kinematically coupled to the said transmissions. The reducer output shaft (7) is included in the planetary gear. The intermediate shaft (5) is installed between the input and output shafts and rests upon a spherical bearing support made as a radial rolling bearing (10), in the inner race (9) of the latter there set is a spherical element (8) made on at least one of the said shafts and conjugated with the said inner race of the radial rolling bearing in a movable way.

EFFECT: invention allows for the decrease of weight and dimensions of a reducer, reducer is small-sized and its price is lowered.
