Level four combination planetary reducer based on NGWN transmission principle

The utility model relates to a level four combination planetary reducer based on NGWN transmission principle, including input gear axle, one -level output gear, planet wheel, ring gear, worm wheel, worm, planet wheel carrier, tertiary output gear, terminal input gear axle, output gear axle, the ring gear passes through the worm wheel to be connected with the worm, and the ring gear passes through the planet wheel to be connected with one -level output gear, one -level output gear and input gear hub connection, and tertiary input gear is connected through the planet wheel carrier to the planet wheel, and tertiary input gear is through terminal input gear hub connection output gear axle. The electronic input shaft of input gear hub connection, the manually enter the axle is connected to the worm. The level four that adopts the speed reduction of two -stage straight -tooth, the speed reduction of single -stage planet wheel and single -stage helical gear speed reduction combination makes up the speed reducer, can
