Description
Technical field
The utility model is related to a kind of planetary reduction gear, more particularly to a kind of bearing mounting structure of planetary reduction gear.
Background technology
It is set in numerically-controlled machine tool, Metal Cutting, food machinery, solar power generation, textile printing and dyeing, printing pharmaceutical equipment, environmental protection
In standby equal light industries, be widely applied to retarder, the retarder applied in above-mentioned industry, usually require that it is small, turn
Fast height, long lifespan, low noise and easy for installation；However existing planetary reduction gear, it is also arranged between output shaft and upper flange
There are upper bearing (metal) and lower bearing, is detached by snap ring between upper and lower bearing, however after using certain time, snap ring is easy to send
It arrives, planetary reduction gear is caused to generate noise at runtime.
Invention content
The purpose of this utility model is to provide a kind of bearing mounting structures of the planetary reducer of low noise.
A kind of planetary reduction gear, including gear ring, upper flange, lower flange, planetary gear set and output shaft, upper flange and laxative remedy
Blue lid respectively is located at the both ends of gear ring, and the planetary gear set is arranged in gear ring and is intermeshed with the inner ring of gear ring, institute
It states that output shaft and planetary gear set are sequentially connected and one end is pierced by upper flange, has at the inner ring of the upper flange and extend inwards
Land portion, the lower section in the land portion are equipped with the lower bearing being set on output shaft, and the top in the land portion, which is equipped with, to be set in
The internal diameter of upper bearing (metal) on output shaft, the land portion is more than outer diameter of the diameter less than upper bearing (metal) and lower bearing of output shaft.
Further, it is equipped with catch between the planetary gear set and lower flange, has for fixing catch in lower flange
Mounting groove, the catch is equipped with through-hole corresponding with planetary gear set, and the diameter of catch is less than the diameter of lower flange.
Further, the periphery of the gear ring, which also has, is used for anti-skidding anti-slip tank.
The beneficial effects of the utility model are：By at the inner ring of upper flange be arranged a land portion, land portion it is interior
Diameter is more than the diameter of output shaft and the outer diameter less than upper and lower bearing so that upper and lower bearing can be separately mounted to the upper of land portion
Side and lower section, and separated by land portion, while output shaft will not be interfered by land portion, being used for a long time not
Friction can be generated with land portion, and saves the cost of a snap ring, and upper and lower bearing is easier for installation；It solves because of snap ring
It loosens and abnormal sound is caused to have the problem of noise.
Description of the drawings
Fig. 1 is the cross-sectional view of the utility model.
Specific implementation mode
The utility model is further described below in conjunction with attached drawing：
As shown in Figure 1, the present embodiment provides a kind of planetary reduction gear, including gear ring 1, upper flange 2, lower flange 3, planet tooth
Wheel group 4 and output shaft 5, upper flange 2 and lower flange 3 cover the both ends for being located at gear ring 1 respectively, and the planetary gear set 4 is arranged in tooth
It is intermeshed in circle 1 and with the inner ring of gear ring 1, the output shaft 5 is sequentially connected with planetary gear set 4 and one end is pierced by method
Orchid 2, has the land portion 21 extended inwards at the inner ring of the upper flange 2, the lower section in the land portion 21 be equipped be set in it is defeated
Lower bearing 6 on shaft 5, the top in the land portion 21 are equipped with the upper bearing (metal) 7 being set on output shaft 5, the land portion 21
Internal diameter be more than output shaft 5 diameter be less than upper bearing (metal) 7 and lower bearing 6 outer diameter.
Further, it is equipped with catch 31 between the planetary gear set 4 and lower flange 3, has for fixing in lower flange 3
The mounting groove of catch 31, the catch 31 is equipped with through-hole 32 corresponding with planetary gear set 4, under the diameter of catch 31 is less than
The diameter of flange 3；Catch 31 can prevent lubricating grease to be lost in, due to the through-hole 32 at catch 31 in order to 4 phase of planetary gear set
Corresponding, which is eccentric orfice, and catch 31 can just be fixed in gear ring 1 and not shake.
Further, the periphery of the gear ring 1, which also has, is used for anti-skidding anti-slip tank 11；Setting 11 structure of anti-slip tank makes
Upper and lower flange will not skid in dismounting, improve production efficiency.
By the way that a land portion 21 is arranged at the inner ring of upper flange 2, the internal diameter in land portion 21 is more than the diameter of output shaft 5
And less than the outer diameter of upper and lower bearing so that upper and lower bearing can be separately mounted to above and below land portion 21, and be led to
It crosses land portion 21 to separate, while output shaft 5 will not be by the interference in land portion 21, it will not be with land portion being used for a long time
21 generate friction, and save the cost of a snap ring, and upper and lower bearing is easier for installation；It solves and is led because snap ring loosens
Abnormal sound is caused to have the problem of noise.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new
