Description
Technical field
This utility model belongs to decelerator technical field, is specifically related to a kind of secondary planetary gear group.
Background technology
The principle of planetary reduction gear is a kind of power transmission mechanism, utilizes the velocity transducer of gear, by the revolution of motor
Number decelerates to desired winding number, and obtains the mechanism of bigger torque.The gear that the number of teeth on planetary reduction gear power transmission shaft is few is nibbled
Close the gear wheel on output shaft to reach the purpose slowed down.Common reductor also has several gear to same principle and engages
Reach preferable slowing effect, the ratio of the number of teeth of size gear, it is simply that gear ratio.Planetary reduction gear is a kind of broad-spectrum work
Industry product, be mainly used in lifting, excavate, transport, the industry such as building, the application in excavating industry is the most extensive.
But, in use there are some defects, such as, current planet wheel decelerator in existing planet accelerator
There will be that slowing effect is the best, noise big, poor stability in actual applications, equipment the most easily breaks down.
Summary of the invention
The purpose of this utility model is to provide a kind of secondary planetary gear group, to solve to propose in above-mentioned background technology
Actual application there will be slowing effect is the best, noise big, poor stability, the problem that equipment the most easily breaks down.
For achieving the above object, this utility model following technical scheme of offer: a kind of secondary planetary gear group, including the sun
The gear teeth (5), planetary gear and ring gear (1), described planetary gear includes mafor planet gear (4) and small planetary gear (6), described
Mafor planet gear (4) is meshed with ring gear (1), and described small planetary gear is meshed with solar wheeling tooth, and mafor planet gear (4)
The both sides of tooth be provided with baffle ring (3), the left side of described small planetary gear (6) is provided with planet thrust washer (2), described planet tooth
The left and right sides of wheel shaft (9) is respectively arranged with needle bearing (8), and the outside of planetary gear axle (9) is inlaid with planet axle sleeve
(7).
Further, fixing even by planetary gear axle (9) between described small planetary gear (6) and mafor planet gear (4)
Connect.
Further, described planetary quantity is 3.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, use secure side
Just, it is possible to increase gear-driven stability, slowing effect can be improved simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the planetary partial sectional view of this utility model；
In figure: 1-ring gear, 2-planet thrust washer, 3-major planet wheel baffle ring, 4-mafor planet gear, 5-solar wheeling tooth,
6-small planetary gear, 7-planet axle sleeve, 8-needle bearing, 9-planetary gear axle.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1 and Fig. 2, a kind of technical scheme of this utility model offer: a kind of secondary planetary gear group, including the sun
The gear teeth (5), planetary gear and ring gear (1), described planetary gear includes mafor planet gear (4) and small planetary gear (6), little row
The middle position of star gear 6 is provided with solar wheeling tooth 5, and described mafor planet gear (4) is meshed with ring gear (1), described little
Planetary gear is meshed with solar wheeling tooth, and the both sides of the tooth of mafor planet gear (4) are provided with baffle ring (3), described small planetary gear
(6) left side is provided with planet thrust washer (2), and the left and right sides of described planetary gear axle (9) is respectively arranged with needle bearing
, and the outside of planetary gear axle (9) is inlaid with planet axle sleeve (7) (8).
Described planetary quantity is that 3, i.e. mafor planet gear 4 and small planetary gear 6 are 3.Small planetary gear 6
It is connected by planetary gear axle 9 is fixing with between mafor planet gear 4.Tooth is passed through between solar wheeling tooth 5 and three small planetary gears 6
Wheel is connected by meshing transmission.Three mafor planet gears 4 are connected by meshed transmission gear with ring gear 1.
Operation principle of the present utility model and use flow process: after this utility model installs, three mafor planet gears 4 with
Being connected by meshed transmission gear between ring gear 1, small planetary gear 6 is connected with mafor planet gear 4 by planetary gear axle 9,
Solar wheeling tooth 5 is arranged in the middle of three small planetary gears 6, and is connected by meshing transmission with three small planetary gears 6 respectively, uses this
Structure, it is possible to increase gear-driven stability, can improve slowing effect simultaneously.
Embodiment the most of the present utility model, for the ordinary skill in the art,
It is appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, repair
Changing, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
