Description
Technical field
This utility model relates to reduction box technical field, is specifically related to a kind of particular row carrier and seals structure.
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 particular row carrier increased the service life seals structure.
For achieving the above object, technical scheme provided by the utility model is: a kind of particular row carrier seals structure, its
Including the motor being sequentially connected with, motor adpting flange, internal tooth and output adpting flange lid, in described internal tooth, it is provided with planetary gear
Group, described output adpting flange lid is provided with, by bearing, the output shaft being connected with the planet carrier in described planetary gearsets,
The cylindrical of described planet carrier is more than the root circle of internal tooth, a side position radial depressions formation one of described internal tooth and this planet carrier phase
Adaptive cooperation counterbore, the opposite side position of described internal tooth is provided with the pad that can be closed by the screw mounting hole on motor adpting flange
Sheet, the external diameter of this pad is more than the root circle of internal tooth.
A kind of improving as of the present utility model, described planet carrier is with described to coordinate counterbore be matched in clearance.
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, and the cylindrical of described planet carrier is big
In the root circle of internal tooth, effectively the gap of internal tooth with the planet tooth in planetary gearsets is blocked, and connected by output
Cooperation counterbore on blind flange matches with planet carrier, effectively stops oils and fats to run off to output shaft direction, can be had by pad
Effect stops oils and fats to run off to motor drive direction, is greatly promoted the sealing effectiveness of planetary gearsets working position, it is to avoid oils and fats runs off, and enters
And fully ensured that sufficient lubrication and the persistency of planetary gearsets working position oils and fats, and high lubricating effect, it is greatly prolonged and makes
With the life-span, 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 particular row carrier that the present embodiment provides seals structure, and 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
It is provided with the output shaft 7 being connected with the planet carrier 51 in described planetary gearsets 5, described row by bearing 6 on adpting flange lid 4
The cylindrical of carrier 51 is more than the root circle of internal tooth 3, a side position radial depressions formation one of described internal tooth 3 and this planet carrier 51 phase
Adaptive cooperation counterbore 31, the cylindrical of described planet carrier 51 is more than the root circle of internal tooth 3, effectively to internal tooth 3 and planetary gearsets 5
In the gap of planet tooth block, and by coordinating matching of counterbore 31 and planet carrier 51 on output adpting flange lid 4
Close, effectively stop oils and fats to run off to output shaft 7 direction.
The opposite side position of described internal tooth 3 is provided with the pad 8 that can be closed by the screw mounting hole on motor adpting flange 2,
The external diameter of this pad 8, more than the root circle of internal tooth 3, can effectively stop oils and fats to run off to motor 1 direction by pad 8.
It is also preferred that the left described planet carrier 51 coordinates counterbore 31 for matched in clearance with described, it is to avoid stuck phenomenon, also try one's best simultaneously
Reduce the loss of power.
In the present embodiment, described pad 8 is stainless steel gasket, and good sealing effect, service life is long.
During work, owing to the cylindrical of described planet carrier 51 is more than the root circle of internal tooth 3, can be effectively to internal tooth 3 and planet tooth
The gap of the planet tooth in wheels 5 blocks, and by the cooperation counterbore 31 on output adpting flange lid 4 and planet carrier 51
Match, effectively stop oils and fats to run off to output shaft 7 direction, then can effectively stop oils and fats to flow to motor 1 direction by pad 8
Lose, be greatly promoted the sealing effectiveness of planetary gearsets 5 working position, it is to avoid oils and fats runs off, and then has fully ensured that planetary gear
Organizing sufficient lubrication and the persistency of 5 working position oils and fatss, high lubricating effect, service life is long.
