(6) Reducti Reduction on Unit (2-stage (2-stage planet planetary ary))

Refer Refer to the cross cross sectio sectional nal view. view. The The moto motorr shaf shaftt (22) (22) is conn connec ecte ted d to the the driv drive e gear gear (16) (16) with with the the spli spline ne on it. it. The The drivi driving ng powe powerr on the hydrauli hydraulic c motor motor is transm transmitt itted ed from from the drive gear (16) (16) to the planetar planetary y gear gear (14) (14) which which is engage engaged d to the the driv drive e gear gear (16) (16).. The The plan planet etar ary y gear gear (14) (14) is enga engage ged d to the the ring ring gear gear on the the redu reduct ctio ion n unit unit housin housing g (1). (1). Then Then it revolv revolves es around around the ring ring gear gear with with its rotation rotation.. The The planet planetary ary gear (14) (14) is held held on the holder (10) with with the bearin bearing, g, and the holder holder (10) (10) transm transmits its the revolv revolving ing motio motion n of planet planetary ary gear  (14) to the sun gear (66) which is engaged to the holder (10) with the spline on it. The sun gear  (66) (66) is engage engaged d to the planet planetary ary gear (68), (68), and transmits transmits the revolv revolving ing motion motion to the planetary planetary gear  gear  (68) (68) as the the same same rout routin ing g as the the firs firstt stag stage. e. Sinc Since e the the plan planet etar ary y gear gear (68) (68) is held held on the the hold holder er (72) (72)  with the bearing, the holder (72) transmits the revolving motion of the planetary gear (68) to the pini pinion on shaf shaftt (2) (2) whic which h is enga engage ged d to the the pini pinion on shaf shaftt (2) (2) with with the the spli spline ne on it. it.
