Abstract
The utility model relates to a speed reducer, include: the motor, speed reducer constructs and the output shaft, and the speed reducer structure includes: input gear, carrier gear, drive gear, planetary gear, output gear and bearing, input gear is connected with the motor, and carrier gear and input gear are connected, and drive gear and carrier gear are connected, and coaxial the setting have a plurality of planetary gear around the output gear, and planetary gear is connected with output gear between drive gear and output gear and the output shaft. Carrier gear and the straight -tooth speed reducer that drive gear constitutes construct the noise that can reduce speed reducer effectively, and planetary gear constructs the life that can improve speed reducer effectively with the planet speed reducer that output gear constitutes.
Description
Technical field
The utility model relates to a kind of reductor.
Background technology
In order to reduce the rotating speed that motor exports, people can use reductor usually.At present, used and more had the reductor of straight tooth structure and the reductor of planetary structure.But although the reductor electric current of straight tooth structure is little, noise is low, and its useful life is shorter; Although the reductor long service life of planetary structure, noise is larger.
Utility model content
A kind of reductor that the utility model provides to solve the problem comprises: motor, reducing gear and output shaft, described reducing gear comprises: input gear, carrier gear, travelling gear, planetary gear, output gear and bearing, described input gear is connected with described motor, described carrier gear is connected with described input gear, described travelling gear is connected with described carrier gear, described travelling gear and coaxial setting between described output gear and described output shaft, there is around described output gear multiple described planetary gear, and described planetary gear is connected with described output gear.
Preferably, described output gear is between described bearing and described travelling gear.
Preferably, described output gear is two, and described reducing gear also has planet carrier, and described planet carrier is between described two output gears.
Preferably, described reducing gear also has output shelf, described output shelf between described output gear and described bearing, coaxial setting between described output shelf and described output gear.
Preferably, there are three described planetary gears around described output gear.
Preferably, described reducing gear also comprises shell, described input gear, described carrier gear, described travelling gear, described planetary gear, and described output gear and described bearing are positioned at described enclosure.
The beneficial effects of the utility model are: the spur reduction mechanism that carrier gear and travelling gear are formed can reduce the noise of reductor effectively, and the planetary gear speed reducing mechanism that planetary gear and output gear are formed can improve the useful life of reductor effectively.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the reductor that the utility model relates to;
Fig. 2 is the interior views of the reductor that the utility model relates to;
Fig. 3 is the cross section view of the reductor that the utility model relates to.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated:
As shown in Figure 1, reductor 100 comprises: motor 10, reducing gear 20 and output shaft 30 3 part composition.Motor 10 is for providing power; Reducing gear 20 is connected with motor 10, for reducing the rotating speed that motor 10 exports; Output shaft 30 is connected with reducing gear 20, for externally providing power.
Shown in composition graphs 2 and Fig. 3, reducing gear 20 comprises input gear 21, spur reduction mechanism 22a, planetary gear speed reducing mechanism 22b and bearing 23.Reducing gear 20 also has shell, input gear 21, and spur reduction mechanism 22a, planetary gear speed reducing mechanism 22b and bearing 23 are all arranged on this enclosure.Wherein, input gear 21 is connected with motor 10, and bearing 23 is connected with output shaft 30.
Spur reduction mechanism 22a comprises carrier gear 221 and travelling gear 222.Carrier gear 221 is connected with input gear 21, and travelling gear 222 is coaxial with output shaft 30, is interconnected between carrier gear 221 and travelling gear 222.
Planetary gear speed reducing mechanism 22b comprises multiple planetary gear 223, output gear 224 and output shelf 226.There is around output gear 224 multiple planetary gear 223, and planetary gear 223 is connected with output gear 224.Output gear 224 and output shelf 226 and coaxial setting between travelling gear 222 and output shaft 30.Output gear 224 is between bearing 23 and travelling gear 222.Output shelf 226 is between bearing 23 and output gear 224.In the present embodiment, planet acceleration mechanism 22b comprises two output gears 224, is provided with between three planetary gears, 223, two output gears 224 and is provided with planet carrier 225 around each output gear 224.
During motor 10 input power, because rotating speed is very fast, therefore can cause larger noise; And output shaft 30 externally provides power due to needs, therefore load is comparatively large, damages gear than being easier to.
There is the reductor 100 of said structure, due to spur reduction mechanism 22a and input gear 21, namely motor 10 is connected to, and planetary gear speed reducing mechanism 22b is connected with bearing 23, namely output shaft 30 is connected to, therefore, the spur reduction mechanism 22a that carrier gear 221 and travelling gear 222 are formed can reduce the noise of reductor 100 effectively, and the planetary gear speed reducing mechanism 22b that planetary gear 223 and output gear 224 are formed can improve the useful life of reductor 100 effectively.
The above embodiment, just preferred embodiments of the present utility model, be not limit practical range of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model claim change or modify, and all should be included in the utility model patent claim.
