Technical field
This utility model relates to reduction box technical field, is specifically related to a kind of special flange sealed construction.
Background technology
Increasingly extensive along with the increasingly mature of brushless electric machine technology and application, makes carrying at double in service life of motor
High.Thus life requirements to reduction box is more and more higher.Because motor and reduction box are typically to use in pairs.Planetary reduction gear exists
In reduction box due to lightweight, volume is little, gear range is big, efficiency is high, smooth running, moment of torsion are big, the low strong adaptability of noise
Extensively selected by every profession and trade etc. feature.But existing planetary reduction box has following lacking due to the limitation of original structure in working
Fall into: 1, working position oils and fats can be by the teeth groove of output shaft planet carrier and ring gear to the interstitial flow of outfan.2, work portion
Position oils and fats can flow to the spaces such as the screwed hole of motor adpting flange by teeth groove to motor drive direction, by the space of motor gear to horse
Reach and flow at bearing.
Owing to drawbacks described above can cause problems with, first, oils and fats can pollute output shaft bearing to the flowing of output shaft direction,
The most too much oils and fats can flow to outside reduction box, also can pollute miscellaneous part.Second, oils and fats flows to motor shaft end then can pollute horse
Reach, seriously can affect motor performance, even motor failure.3rd, owing to planetary reduction box working position oils and fats is in its life-span
Cycle can only fill an oils and fats, so oil quality and loss whether life-span to planetary reduction box is crucial, oils and fats
Run off, the service life of reduction box will be greatly shortened.
Utility model content
For above-mentioned deficiency, the purpose of this utility model is, it is provided that a kind of smart structural design, rationally, effectively promotes
Sealing effectiveness, it is to avoid oils and fats runs off, the special flange sealed construction increased the service life.
For achieving the above object, technical scheme provided by the utility model is:
A kind of special flange sealed construction, it includes that the motor, motor adpting flange, internal tooth and the output that are sequentially connected with connect
Acting flange lid, is provided with planetary gearsets, described output adpting flange lid is provided with and described planet by bearing in described internal tooth
The output shaft that planet carrier in gear train is connected, on the inwall of described internal tooth, radially cave in and form annular in corresponding row carrier position
Recess, the end face that described output adpting flange lid is connected with internal tooth axially convexes to form the annular that can insert this annular recess
Projection, the cylindrical of this annular protrusion is more than the outer peripheral face of the root circle of internal tooth, the inner hole wall of this annular protrusion and described planet carrier
Matching, described internal tooth is provided with the pad that can be closed by the screw mounting hole on motor adpting flange, and the external diameter of this pad is big
Root circle in internal tooth.
As a kind of improvement of the present utility model, between the inner hole wall of described annular protrusion and the outer peripheral face of described planet carrier are
Gap coordinates, and the cylindrical of this annular protrusion is more than the root circle of internal tooth.
As a kind of improvement of the present utility model, described pad is stainless steel gasket.
The beneficial effects of the utility model are: this utility model smart structural design, rationally, by output adpting flange lid
On annular protrusion and annular recess on internal tooth suitable, effectively stop oils and fats to run off to output shaft direction, by pad energy
Effectively stop oils and fats to run off to motor drive direction, be greatly promoted the sealing effectiveness of planetary gearsets working position, it is to avoid oils and fats runs off,
And then fully ensured that sufficient lubrication and persistency, the high lubricating effect of planetary gearsets working position oils and fats, it is greatly prolonged
In service life, additionally overall structure is simple, it is easy to accomplish, low cost, beneficially wide popularization and application.
Below in conjunction with the accompanying drawings with embodiment, this utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model.
Fig. 2 is the decomposition texture schematic diagram of Fig. 1.
Detailed description of the invention
Seeing Fig. 1 and Fig. 2, a kind of special flange sealed construction that the present embodiment provides, it includes the electricity being sequentially connected with
Machine 1, motor adpting flange 2, internal tooth 3 and output adpting flange lid 4, be provided with planetary gearsets 5, described output in described internal tooth 3
