Abstract
The utility model discloses a kind of lip-shaped sealed ring for running shaft, main contents are: comprise the outer hub of oil sealing, rubber ring, hub in oil sealing, metal spring, metal frame and the main lip of oil sealing, it is characterized in that, described rubber ring to be fixedly mounted in oil sealing in hub endoporus by binder, the main lip endoporus of oil sealing to be arranged in oil sealing on hub external cylindrical surface, metal spring is stuck in oil sealing main lip right-hand member groove, be stuck in oil sealing main lip left end notch bottom metal frame, oil sealing outer hub stage casing inner hole sleeve is in oil sealing on hub left end external cylindrical surface, the outer hub right-hand member inner hole sleeve of oil sealing on metal frame external cylindrical surface and metal frame right side withstand on the outer hub right-hand member step of oil sealing.The utility model structure is simple, and cost is low, effectively reduces the interference of the outside unfavorable factors such as the coaxality of axle, surface roughness, axle out of roundness to sealing, also makes installation become easy simultaneously, improve sealing effect, extend working life.
Description
Technical field
The utility model relates to technical field of sealing technology, particularly relates to a kind of lip-shaped sealed ring for running shaft.
Background technique
The sealing of oil sealing is formed by the interference fit between a flexible seal (leather, rubber, teflon, polychlorotrifluoroethylene etc.) and running shaft.In structural design, the oil sealing due to a large amount of employing a few days ago directly carries out interference fit with running shaft and realizes motive sealing, and its coaxality to running shaft, size deviation, out of roundness, surface roughness etc. have very strict requirement; In installing and using.A little lubricating grease must be first coated with on oil seal lip before installation, because oil sealing lip has a magnitude of interference relative to axle, must be noted that during installation and prevent the torsion of such as sealed lip, extrude, when axle head be not with circular cone, fillet and have screw thread time, just more it should be noted that otherwise easily lip scratched and affect sealing effect; The damage of existing oil sealing to axle surface is more responsive, and very slight damage all may produce impact greatly to its sealing effect and operating life, even directly brings leakage.
Model utility content
According to above deficiency, the utility model provide that a kind of cost is low, long service life, reliability are high and fitting operation easily for the lip-shaped sealed ring of running shaft.
For achieving the above object, the utility model is used for the lip-shaped sealed ring of running shaft, main contents are: comprise the outer hub of oil sealing, rubber ring, hub in oil sealing, metal spring, metal frame and the main lip of oil sealing, it is characterized in that, described rubber ring to be fixedly mounted in oil sealing in hub endoporus by binder, the main lip endoporus of described oil sealing to be arranged in oil sealing on hub external cylindrical surface, described metal spring is stuck in oil sealing main lip right-hand member groove, be stuck in oil sealing main lip left end notch bottom described metal frame, described oil sealing outer hub stage casing inner hole sleeve is in oil sealing on hub left end external cylindrical surface, the outer hub right-hand member inner hole sleeve of described oil sealing on metal frame external cylindrical surface and metal frame right side withstand on the outer hub right-hand member step of oil sealing.
As preferably, the outer hub right-hand member endoporus of described oil sealing is processed with annular groove near right side.
As preferably, described rubber ring endoporus is wavy shaped configuration.
As preferably, described rubber ring left end is dustproof lip structure and its outer surface withstands on the outer hub endoporus of oil sealing.
As preferably, in described oil sealing, hub is flange arrangement.
The utility model beneficial effect is: structure is simple, and cost is low, effectively reduces the interference of the outside unfavorable factors such as the coaxality of axle, surface roughness, axle out of roundness to sealing, also makes installation become easy simultaneously, improve sealing effect, extend working life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals:
The outer hub of 1-oil sealing, 2-rubber ring, hub in 3-oil sealing, 4-metal spring, 5-metal frame, the main lip of 6-oil sealing.
Embodiment
Below in conjunction with drawings and Examples, the utility model embodiment is described:
These system main contents are: comprise the outer hub 1 of oil sealing, rubber ring 2, hub 3 in oil sealing, metal spring 4, metal frame 5 and the main lip 6 of oil sealing, it is characterized in that, described rubber ring 2 to be fixedly mounted in oil sealing in hub 3 endoporus by binder, described oil sealing main lip 6 endoporus to be arranged in oil sealing on hub 3 external cylindrical surface, described metal spring 4 is stuck in oil sealing main lip 6 right-hand member groove, be stuck in oil sealing main lip 6 left end notch bottom described metal frame 5, described oil sealing outer hub 1 stage casing inner hole sleeve is in oil sealing on hub 3 left end external cylindrical surface, the outer hub 1 right-hand member inner hole sleeve of described oil sealing on metal frame 5 external cylindrical surface and metal frame 5 right side withstand on the outer hub 1 right-hand member step of oil sealing.
A wavy rubber ring 2 of coated one deck is devised between hub 3 in described running shaft and oil sealing; During work, in oil sealing, hub 3 is with coaxially rotating, and oil sealing realizes motive sealing in its lip and oil sealing between hub 3 outer surface; In oil sealing, the wavy rubber ring 2 of the coated one deck of hub 3 part, can adapt to the larger malalignment of running shaft and larger size deviation, has axial and radial shock-absorbing capacity preferably; Because sealing realizes between hub 3 in oil sealing lip and oil sealing, thus not high to the out of roundness of axle, surface roughness requirements, also insensitive to the slight damage on axle surface, improve the reliability of oil sealing; In oil sealing, coated one deck rubber on hub 3, can make oil sealing firmly be arranged on axle; Between oil pocket and the external world, devise a mazy passage, and arrange twice dust excluder lips in the channel, make the main lip 6 of oil sealing keep a segment distance with dust and water, extend the working life of oil sealing.
By reference to the accompanying drawings the utility model preferred implementation is explained in detail above, but the utility model is not limited to above-mentioned mode of execution, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that the utility model is not limited to specific mode of execution, scope of the present utility model is defined by the following claims.
