Description
Technical field
It the utility model is related to a kind of reducing motor, more particularly to a kind of reducing motor of the anti-oil leak device of band.
Background technology
Lubricating oil is all generally marked with the housing of decelerator in reducing motor, to reduce the friction between rotatable parts,
Prevent rotatable parts from being damaged because friction causes to generate heat.To prevent the leakage of lubricating oil, between input shaft, output shaft and housing
Can make ring wear provided with sealing ring, when input shaft and output shaft rotation, after ring wear lubricating oil can along input shaft or
Output shaft leaks out, and causes environmental pollution；It is therefore desirable to be improved.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of reducing motor of anti-oil leak, to the profit of leakage
Lubricating oil is collected, and avoids lubricating oil from being spread to periphery.
The technical scheme for the technical problem that the utility model solves is a kind of reducing motor of anti-oil leak, and it is wrapped
The housing 4 of the decelerator in reducing motor is included, rotating shaft 1, rotating shaft is stretched out from housing, and sealing is provided between housing and rotating shaft
Part 3, flange 2 being provided with the outside of seal, flange is connected on housing and pushes down seal, it is characterized in that, the flange
There is a recess 7 in inner circle, an oil pipe 5 is extended downwardly from the bottom of recess, the lower end of oil pipe is provided with lid 6.
The characteristics of the utility model is that recess is provided with the inner circle of flange, forms a cavity, cavity position and rotating shaft without
Contact, when lubricating oil between rotating shaft and seal along when leaking out by cavity, the pressure of lubricating oil greatly reduces, lubricating oil
It can be trapped in the bottom and oil pipe of cavity, will not be spread to the periphery of reducing motor, avoid causing environmental pollution；When crossing one section
Between open oil pipe lower end lid by cavity and oil pipe oil release, can prevent from overflowing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Accompanying drawing mark represents respectively：1- rotating shafts, 2- flanges, 3- seals, 4- housings, 5- oil pipes, 6- lids, 7- recesses,
8- bolts, 9- springs, 10- nuts, 11- bulge loops, 12- packing seal letters.
Embodiment
In conjunction with brief description of the drawings specific embodiment of the present utility model.
A kind of reducing motor of anti-oil leak, is made up of motor and decelerator, the main shaft and decelerator of motor
Rotating shaft 1 connect, rotating shaft 1 is stretched out from the left side of the housing 4 of decelerator, and seal 3 is provided between housing and rotating shaft,
The outside of seal is provided with flange 2, and flange is connected on housing and pushes down seal, and the left side of flange is managed along a body is stretched out
A recess 7 is provided with the inner circle of body, extends downwardly from an oil pipe 5 in the bottom of recess, the wall body of oil pipe and recess seals, oil pipe
Lower end is provided with lid 6.
Above-mentioned structure can effectively prevent leakage lubricating oil diffusion, its principle is, lubricating oil is along rotating shaft and seal
Between gap when leaking out with certain pressure, and gap becomes big when lubricating oil passes through the recess in flange, makes lubrication
The pressure of oil, which substantially reduces, to be difficult to move ahead, and lubricating oil can be trapped in recess, and the oil in recess can be drawn and avoid overflowing by oil pipe.
To improve the sealing property of decelerator, reduce the leakage of lubricating oil, extend a bulge loop 11 on the right side of described flange,
Extend a packing seal letter 12 on the left of described housing, the right-hand member of bulge loop is put in packing seal letter, bulge loop it is cylindrical with
The inner circle of packing seal letter is engaged, and the inner circle of bulge loop is engaged with rotating shaft, and described seal is graphite packing, graphite packing
In packing seal letter, the left end of packing seal letter extends radially out a disk, bolt 8 and nut 10 by flange and filler
The disk connection of sealed letter, graphite packing is compressed.So when sealing property declines, nut can be screwed again, with
Keep sealing property；Sealing maintenance can be carried out online compared with traditional sealing ring, without changing sealing ring.
Further to improve sealing property, spring 9 can be provided between the disk of nut and packing seal letter, when filler is close
Tension force of spring can automatic impaction packing seal during envelope abrasion.
The anti-oil leak dress of said structure is again provided between another rotating shaft and housing on the right side of reducer shell
Put（Do not drawn in accompanying drawing）.
