Abstract
The utility model relates to a speed reducer, in particular to a coaxial type gear reducer. The coaxial type gear reducer comprises a box body; a shaft is penetrated and connected in the box body; an inner shaft is arranged in the box body; a large gear is sheathed at the upper end of the shaft; a small first-stage gear is sheathed at the lower end of the shaft; a small gear is sheathed at the upper end of the inner shaft; a large first-stage gear is sheathed at the lower end of the inner shaft; the large gear is meshed with the small gear; the small first-stage gear is meshed with the large first-stage gear; the upper end of the shaft is fixed with the box body through a tapered roller bearing; and the lower end of the shaft is fixed with the box body through an annular contact ball bearing. The coaxial type gear reducer has simple structure and good using effect.
Description
Technical field
The utility model is a kind of retarder, particularly a kind of coaxial-type gear reducer.
Background technique
