Description
Technical field：
The present invention relates to sealing structure technical fields, and in particular to a kind of small angle of cut gear train assembly is close with sound combination
Seal structure.
Background technique：
Small angle of cut gear train assembly can realize parallel axes, concurrent aces, crossed-axes gear drive mode according to requirement of engineering, therefore
Type transmission is widely used in robot arm, speedboat, high-speed production lines and the fields such as radar steering and tracking system.One
As in the case of, small angle of cut gear train assembly use forced feed lubrication, that is, oil jet lubrication mode, under the conditions of continuous oil jet lubrication,
A part is used to support bearing lubrication for gear engagement lubrication, a part, and the lubricating oil after lubrication can largely pass through gravity
Oil return returns to fuel tank and is recycled, but there are also sub-fractions, can be because of the splashing of lubricating oil, along axis to outside gear-box
Flowing, and the sealing of lubricating oil then relative difficulty at this, sealing generallys use two ways at this：Contact seal mainly includes
Three kinds of packing seal, shaped packing seal and mechanical seal forms, its main feature is that structure is simply easily installed, the disadvantage is that filler etc.
Seal form is prone to wear, service life short need, periodic replacement；Non-contacting seal mainly has labyrinth seal, but works as rotating member revolving speed
When higher than 5m/s, lubricating oil is easy to throw away from gap, i.e., is unfavorable for sealing under high revolving speed.The leakage of lubricating oil will cause environment dirt
The problems such as dye, lubricating oil waste.
Therefore, when gear train assembly inputs, output end actuated element revolving speed is higher and structure is complicated, or when transmission dress
Set operating condition it is severe when, then need a kind of sealing structure is significantly more efficient to prevent lubricating oil from revealing, therefore carry out small angle of cut gear
Transmission system is very necessary with sound combined sealing structure.
Summary of the invention：
In place of overcoming above-mentioned the shortcomings of the prior art, and provide a kind of small angle of cut gear
Transmission system sound combined sealing structure, it carries out oil seal using multi-sealing structure, highly effective can reduce
Lubricating oil leakage problem.
The technical solution adopted by the present invention is：A kind of small angle of cut gear train assembly sound combined sealing structure, by outer
End cap, inner end cap, injection loop, positioning ring, axis, spring bearing, oil scraper ring, labyrinth seal, asbestos washer, locking nut, graphite
Sealing ring, lip-type packing composition, shaft end portion is successively cased with outer end cap and inner end cap, outer end cap and inner end on convex edge from left to right
Lid is connected by fastening bolt, and lip-type packing is equipped between outer end cap and axis, and graphite is equipped between the inner end cap and axis
Sealing ring；Labyrinth seal, oil scraper ring, spring bearing and positioning ring are successively cased on axis outer wall from left to right, the labyrinth is close
Envelope is equipped with injection loop by locking nut and axis connection, the oil scraper ring.
One end face of inner end cap is equipped with asbestos washer.
The labyrinth seal and Axile connection structure is mechanical non-contacting sealing structure.
The connection structure of the lip-type packing and graphite-seal ring and axis is Mechanical contacted seals structure.
The beneficial effects of the invention are as follows：This small angle of cut gear train assembly sound combined sealing structure passes through three seals
Ordered arrangement carries out separation sealing to lubricating oil one by one, while can also play the entrance for preventing external water, impurity etc., reduces tooth
Wheel transmission system internal element meets the risk of aquatic rust, can also reduce maintenance frequency using combined sealing structure, reach one
Fixed economic benefit.
Detailed description of the invention：
Fig. 1 is schematic structural view of the invention.
Specific embodiment：
Referring to Fig.1, a kind of small angle of cut gear train assembly sound combined sealing structure, by outer end cap 1, inner end cap 2, spray
Oil ring 3, positioning ring 4, axis 5, spring bearing 6, oil scraper ring 7, labyrinth seal 8, asbestos washer 9, locking nut 10, graphite-seal ring
11, lip-type packing 12 forms, and is successively cased with outer end cap 1 and inner end cap 2 on 5 end convex edge of axis from left to right, outer end cap 1 with it is interior
End cap 2 is connected by fastening bolt, lip-type packing 12 is equipped between outer end cap 1 and axis 5, between the inner end cap 2 and axis 5
Equipped with graphite-seal ring 11；Labyrinth seal 8, oil scraper ring 7, spring bearing 6 and positioning ring are successively cased on 5 outer wall of axis from left to right
4, the labyrinth seal 8 is connect by locking nut 10 with axis 5, and the oil scraper ring 7 is equipped with injection loop 3.Described is interior
2 one end face of end cap is equipped with asbestos washer 9.The labyrinth seal 8 and 5 connection structure of axis is mechanical non-contacting sealing structure.
The connection structure of the lip-type packing 12 and graphite-seal ring 11 and axis 5 is Mechanical contacted seals structure.
Oil seal is carried out using multi-sealing structure in this structure, including contact seal and non-contacting seal
Be applied in combination, being capable of highly effective reduction lubricating oil leakage problem.Lubricating oil is realized by labyrinth seal 8 and the cooperation of inner end cap 2
First of sealing function, the seal style belong to mechanical non-contacting sealing structure, most lubricating oil can be passed through oil return
Hole returns to fuel tank；The sealing of lubricating oil second is realized by graphite-seal ring 11 and the cooperation of inner end cap 2, which belongs to machinery
Remaining lubricating oil can be isolated, prevent from revealing by contact type sealing structure；Lubricating oil is realized by lip-type packing 12 and the cooperation of axis 5
Three seals, type sealing belong to contact type sealing structure, can thoroughly solve lubricating oil leakage problem.
The structure is suitable for the situation that gear drive element revolving speed is higher, structure is complicated, operating condition is severe, more effectively
Prevent lubricating oil from revealing.
In conclusion this small angle of cut gear train assembly passes through three seals ordered arrangement with sound combined sealing structure,
Separation sealing is carried out to lubricating oil one by one, while can also play the entrance for preventing external water, impurity etc., reduces gear train assembly
Internal element meets the risk of aquatic rust, can also reduce maintenance frequency using combined sealing structure, has reached certain economic effect
Benefit.
