Abstract

The utility model discloses the speed reducer that a kind of structure is simple, volume is little, gear range is large, it comprises two groups of planetary gear set, one of them sun gear is fixed on support as input sun gear, another sun gear movable on the concentric circle of input sun gear is as output sun gear, and exporting sun gear is output shaft.The planet wheel coordinated with input sun gear is as line of input star-wheel, the planet wheel coordinated with output sun gear is taken turns as output planetary, line of input star-wheel and output planetary are taken turns and are mutually permanently connected on same shaft axis, line of input star-wheel and output planetary is driven to take turns around two sun crop rotation planetary motions by input shaft, because two planetary gear set existence motion speed are poor, output sun gear is made to create corresponding rotating speed.The utility model is mainly used in the mechanical transmission that power is large, gear range is large.

Description

Speed reducer
Technical field
The utility model belongs to mechanical reduction transmission device.
Background technique
At present, known speed reducer, the gear range of gear reduction unit is little, volume large, and needlework escapement speed reducer volume is large, power is little.
Summary of the invention
In order to overcome less than scope, the bulky shortcoming of existing speed reducer drive, the technical problems to be solved in the utility model is to provide a kind of speed reducer, and the motion speed difference that it have employed two groups of planetary gear set carries out mechanical transmission.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a sun gear in two groups of planetary gear set is fixed on support as input sun gear, another sun gear movable on the concentric circle of input sun gear is as output sun gear, and exporting sun gear is output shaft.The planet wheel coordinated with input sun gear is as line of input star-wheel, the planet wheel coordinated with output sun gear is taken turns as output planetary, line of input star-wheel and output planetary are taken turns and are mutually permanently connected on same shaft axis, line of input star-wheel and output planetary is driven to take turns around two sun crop rotation planetary motions by input shaft, because two planetary gear set existence motion speed are poor, output sun gear is made to create corresponding rotating speed.
The beneficial effects of the utility model are: structure is simple, volume is little, power is large, gear range is large, due to two sun gears with one heart and position partly overlaps, and input output planet wheel is also with one heart and position partly overlaps, so this speed reducer volume is very little.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is fundamental diagram of the present utility model.
In figure 1, input shaft 2, support 3, input sun gear 4, export sun gear 5, output planetary wheel 6, line of input star-wheel.
Embodiment
[0011] output planetary wheel 5 forms one group of planetary gear set with output sun gear 4 in FIG, line of input star-wheel 6 forms one group of planetary gear set with input sun gear 3, input sun gear 3 is fixed on support 2, it is movable on the concentric circle of input sun gear 3 for exporting sun gear 4, and exporting sun gear 4 is output shafts.Output planetary wheel 5 is mutually permanently connected on same shaft axis with line of input star-wheel 6, planetary motion is done around output sun gear 4 and input sun gear 3 while of driving output planetary to take turns 5 and line of input star-wheel 6 by input shaft 1, because two planetary gear set existence speed are poor, output sun gear 4 is made to create corresponding rotating speed.

Claims (1)

1. a speed reducer, it comprises two groups of planetary gear set, it is characterized in that one is fixed on input sun gear on support and a movable output sun gear, the planet wheel coordinated respectively with two sun gears is mutually permanently connected on same shaft axis, drives planet wheel around two sun crop rotation planetary motions by input shaft.
