Abstract
The utility model discloses a kind of cone tooth planetary reduction gear, including input shaft, and input shaft is connected with sun gear across babinet, and the input shaft rotation is connected with output shaft；The columned planet carrier for being fixed with axial symmetry setting is tilted on output shaft, and planetary gear is arranged on planet carrier；Tooth rest is rotatably connected on output shaft；Sun gear is engaged with planetary gear, and planetary gear is engaged with tooth rest；Tooth rest periphery forms conical tooth, and sun gear and planetary gear are conical tooth；Tooth rest is fixed in babinet.The utility model changes the mode of conventional planetary train middle gear axis parallel arrangement, is arranged using space multistory, significantly reduces the radial dimension of planetary reduction gear, keeps reducer structure more compact, application scenario is more extensive.
Description
Technical field
This patent belongs to machinery field more particularly to a kind of cone tooth planetary reduction gear.
Background technology
Existing spur gear planetary reduction gear, it is typically internal that sun gear is set, several rows of engagement are then arranged outside sun gear
Star-wheel, planetary gear are arranged meshing gear frame outside；Such setting causes the radial gear of retarder very big, therefore narrow at some
Underground, interior etc. be inconvenient to install.
Utility model content
To solve the above problems, the utility model discloses a kind of cone tooth planetary reduction gears.The utility model changes biography
The mode for planetary gear train middle gear axis parallel arrangement of uniting, is arranged using space multistory, significantly reduces planetary reduction gear
Radial dimension keeps reducer structure more compact, and application scenario is more extensive.
To achieve the above object, the technical solution of the utility model is：
A kind of cone tooth planetary reduction gear, including input shaft, input shaft are connected with sun gear, the input shaft rotation across babinet
Shaft is connected to output shaft；The columned planet carrier for being fixed with axial symmetry setting is tilted on output shaft, and row is arranged on planet carrier
Star-wheel；Tooth rest is rotatably connected on output shaft；Sun gear is engaged with planetary gear, and planetary gear is engaged with tooth rest；Outside tooth rest
Form conical tooth week, sun gear and planetary gear are conical tooth；Tooth rest is fixed in babinet.
Further to improve, the columned planet carrier is two；Planet carrier is arranged with output shaft at 60 ° of angles.
Further to improve, the babinet includes upper box and lower box；Upper box and lower box are mutually solid by bolt
Fixed connection.
Further to improve, the input shaft is connected by first bearing with babinet；Planetary gear passes through second bearing and row
Carrier is connected；Tooth rest is connected by 3rd bearing with output shaft；Input shaft is connected with output shaft by fourth bearing.
Further to improve, the input shaft is equipped with end cap with babinet junction.
Compared with prior art, the utility model has the following advantages that：
1. the problem of replacing ring gear tooth rest using bevel gear frame, avoiding helical teeth ring gear processing difficulties.
2. not being mutually parallel between the axis of gear, the radial dimension of planetary reduction gear is significantly reduced, retarder is made
Structure is more compact, and application scenario is more extensive.

Specific implementation mode
Embodiment 1
As shown in Figure 1, retarder radiator, including：Input shaft 1, input shaft 1 are integrally formed with sun gear 3.Input shaft
It is provided with bearing between 1 and the endoporus of upper box 4.It is provided with sealing ring between input shaft 1 and end cap 2.Upper box 4 and lower box
7 axis hole is located on same axis, and passes through bolted on connection between upper and lower box.Tooth rest 8 is fixed on by screw on lower box,
The endoporus of tooth rest 8 and babinet axis hole are coaxial.Be provided with bearing between output shaft 9 and tooth rest endoporus, with the axis hole of lower box 7 it
Between be provided with sealing ring.There is a stepped hole in the left side of output shaft, for installing the bearing between input shaft.Outside output shaft
There are two the cylinder boss at 180 degree on circle as planet carrier 6, and two planet carriers are arranged and differ 180 degree and realize power dividing
And counteracting forces, the axis of planet carrier and the axis of output shaft are at an angle.Bearing is installed on planet carrier, is pacified outside bearing
Equipped with planetary gear 5,5 feasibility study planet carrier axis rotation of planetary gear.Planetary gear 5 engages simultaneously with sun gear 3 and tooth rest 8.Change
The mode for becoming conventional planetary train middle gear axis parallel arrangement, is arranged using space multistory, significantly reduces planetary reduction gear
The radial dimension of device keeps reducer structure more compact, and application scenario is more extensive.
Although the embodiments of the present invention have been disclosed as above, it is not restricted to institute in specification and embodiment
Row use, it can be applied to various fields suitable for the present invention completely, for those skilled in the art, can
Easily realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, this practicality
It is novel to be not limited to specific details and the legend herein shown with description.
