Abstract
The utility model discloses a kind of rotary shaft oil seal, including fastening spring, inner frame, sealed outer ring and anti-dust seal lip, inner frame is installed on sealed outer ring inner side, at the anti-dust seal lip of inner frame bottom end embedding sealing outer ring side, and anti-dust seal lip one end is enclosed with fastening spring.The utility model compact conformation, it is easy to use, which reduce the influence of inner frame inner surface quality and rotating shaft surface quality to sealing effectiveness, reduce assembly technology requirement and the manufacturing cost of oil sealing of the processing request, oil sealing of internal skeleton surface quality, and sealing effectiveness is good, so that the impurity such as dust is more difficult to enter lubricating oil, with good economic benefit and social benefit, suitably promote the use of.
Description
Technical field
The utility model is related to a kind of seal, specially a kind of rotary shaft oil seal, belongs to seal field.
Background technology
Oil sealing is the seal of mechanism's rotary shaft, and its effect is to prevent fluid along axial rotary external leakage and prevent outside miscellaneous
Thing invades internal body.As rotation shaft seal, traditional mode in addition to catch oil sealing, also mechanical seal,
Contact and soft packing seal etc..But in these sealing devices, the simple structure of packing seal and catch oil sealing, installation are held
Easily, it is with low cost, be widely used, it has the disadvantage easily leakage failure, packing seal abrasion axle.The rotation of blower fan, reductor etc.
Rotating shaft sealing uses catch oil sealing and packing seal mostly, therefore regarding to the issue above, we have proposed a kind of rotary shaft oil seal.
Utility model content
The utility model provides a kind of rotary shaft oil seal, and fluid easily leaks in can effectively solving practical application, while outward
The problems such as impurity on boundary easily invades internal body.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
A kind of rotary shaft oil seal of the utility model, including fastening spring, inner frame, sealed outer ring and anti-dust seal lip,
The inner frame is installed on sealed outer ring inner side, and the inner frame bottom end is embedded in the anti-dust seal of the sealed outer ring side
At lip, and described anti-dust seal lip one end is enclosed with fastening spring.
Used as a kind of optimal technical scheme of the present utility model, the sealed outer ring and the anti-dust seal lip are rubber
Glue material matter is made.
Used as a kind of optimal technical scheme of the present utility model, the section of the inner frame is L-type structure.
Used as a kind of optimal technical scheme of the present utility model, the anti-dust seal lip bottom is tight with the sealed outer ring
Contiguity is touched.
The beneficial effect that the utility model is reached is：The utility model compact conformation, it is easy to use, which reduce in-seam
The influence of frame inner surface quality and rotating shaft surface quality to sealing effectiveness, the processing for reducing internal skeleton surface quality will
Ask, the assembly technology requirement of oil sealing and the manufacturing cost of oil sealing, and sealing effectiveness is good so that the impurity such as dust is more difficult
To enter lubricating oil, with good economic benefit and social benefit, suitably promote the use of.
Brief description of the drawings
Accompanying drawing is used for providing being further understood to of the present utility model, and constitutes a part for specification, with this practicality
New embodiment is used to explain the utility model together, does not constitute to limitation of the present utility model.In the accompanying drawings：
Fig. 1 is a kind of structural representation of rotary shaft oil seal of the utility model；
In figure：1st, fastening spring；2nd, inner frame；3rd, sealed outer ring；4th, anti-dust seal lip.
Specific embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment：As shown in figure 1, a kind of rotary shaft oil seal of the utility model, including fastening spring 1, inner frame 2, sealing
Outer ring 3 and anti-dust seal lip 4, inner frame 2 are installed on the inner side of sealed outer ring 3, the bottom end embedding sealing outer ring 3 of inner frame 2
At the anti-dust seal lip 4 of side, and the one end of anti-dust seal lip 4 is enclosed with fastening spring 1.
Sealed outer ring 3 and anti-dust seal lip 4 are quality of rubber materials and are made.
The section of inner frame 2 is L-type structure.
The bottom of anti-dust seal lip 4 is in close contact with sealed outer ring 3.
Specifically, after the oil sealing is assembled in rotary shaft, equivalent to increased a road sealing device, both improve oil
The sealing effectiveness of envelope, reduces the influence of inner frame inner surface quality and the internal reinforced seal effect of rotating shaft surface quality again,
Therefore the sealing of the oil sealing is preferable, while reducing the processing request of internal skeleton surface quality and being manufactured into for inner frame
This.The oil sealing is applied to the rotary shaft of rotation at a high speed, and the internal diameter of oil sealing is less than the diameter of axle, just there is certain magnitude of interference, lip after assembling
On tight-lipped last item external cylindrical surface.Because contact surface is narrow, thus its frictional force less than its external cylindrical surface and the hole inner circle hole face installed it
Between frictional force, therefore axle rotation and oil sealing does not rotate with the axis.
The utility model compact conformation, it is easy to use, which reduce inner frame inner surface quality and rotating shaft surface quality
Influence to sealing effectiveness, reduces assembly technology requirement and the oil sealing of the processing request, oil sealing of internal skeleton surface quality
Manufacturing cost, and sealing effectiveness is good so that the impurity such as dust is more difficult to enter lubricating oil, with good economy effect
Benefit and social benefit, suitably promote the use of.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
Utility model, although being described in detail to the utility model with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Carry out equivalent.It is all it is of the present utility model spirit and principle within, any modification, equivalent substitution and improvements made etc.,
Should be included within protection domain of the present utility model.
