Abstract
The utility model discloses a floating oil seal. The floating oil seal comprises a metal floating ring and an O-shaped rubber seal ring, wherein a spherical groove is formed in the outer side of the metal floating ring; the O-shaped rubber seal ring is sleeved into the spherical groove in the outer side of the metal floating ring; and the metal floating ring is preferably a nichrome floating ring, and the O-shaped rubber seal ring is preferably an O-shaped nitrile rubber seal ring. The spherical groove and the O-shaped rubber seal ring are used in coordination, so that the floating oil seal is more stable and reliable in sealing performance and long in service life. The nichrome floating ring is compact in material and excellent in wear resisting property. The floating oil seals can be used in coordination in the way that one is mounted on a floating seal base and is relatively still and the other is mounted in a walking component; the O-shaped rubber seal ring adopts the precise bispherical grinding technology, lubricant in a component cavity is utilized to play roles of even wear and mutual compensation, and external sediment and sewage are effectively prevented from invasion; and the service life can reach more than 4, 000 hours.
Description
Technical field
The utility model relates to a kind of float grease seal.
Background technique
Float grease seal is a kind of novelty, mechanical rotating sealing device compact type that grows up for adapting to abominable working environment, it has advantages of that contamination resistance is strong, wear-resisting, shock-resistant, reliable operation, end wear auto-compensation, use the most generally in the construction machinery product such as bulldozer, excavator and coal mine machinery, heavy truck, also be widely used on various conveyors, sand preparation equipment, concrete equipment.Float grease seal mainly plays a part aspect two in normal operation, and the one, prevent the foreign material intrusions such as outside silt, the 2nd, prevent the leakage of internal lubrication oil.Float grease seal in the market, its airtight performance is unstable, and working life is not long, frequently changes float grease seal and wastes man-hour, and cost is higher, brings very large economic loss.
Because the defective that above-mentioned existing float grease seal exists, the design people, actively research and innovation in addition, to founding a kind of float grease seal of new structure, make it have more practicability.
Summary of the invention
Main purpose of the present utility model is, overcome existing float grease seal airtight performance unstable, the defective that working life is short, it is the sealing effect that strengthens metal floating ring and O shape rubber seal that a kind of float grease seal of new structure, technical problem to be solved are provided, improve simultaneously the wear-resisting property of metal floating ring, to extend the working life of float grease seal, enhance productivity, reduce production costs, thereby more be suitable for practicality, and have the value on industry.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to a kind of float grease seal that the utility model proposes, comprise metal floating ring and O shape rubber seal, the outside of described metal floating ring is provided with spherical groove, and O shape rubber seal is set in the spherical groove in the outside of metal floating ring.
Described metal floating ring is the nichrome floating ring.
Described O shape rubber seal is O shape nitrile butadiene rubber seal ring.
The diameter of described spherical groove is identical with O shape rubber seal loop diameter.
The beneficial effects of the utility model are: the spherical groove design coordinates O shape rubber seal to use, and the float grease seal sealability is more reliable and more stable, long service life.Nichrome floating ring dense materials, wear-resisting property is excellent.O shape nitrile butadiene rubber seal ring decay resistance is good.When the diameter of spherical groove is identical with O shape rubber seal loop diameter, can reduce entering of the foreign matters such as sand, sewage, reduce wearing and tearing.
In sum, the float grease seal of the utility model special construction, it has above-mentioned advantage and use value, thereby more is suitable for practicality.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.
Description of drawings
Fig. 1 is the cross-sectional view of float grease seal described in the utility model.
Embodiment
Be to reach technological means and the effect that predetermined model utility purpose is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, embodiment of the present utility model be described in detail as follows.
As shown in Figure 1, a kind of float grease seal comprises metal floating ring 1 and O shape rubber seal 2, and the outside of metal floating ring is provided with spherical groove 3, O shape rubber seal is set in the outside spherical groove of metal floating ring, preferred nichrome floating ring and O shape nitrile butadiene rubber seal ring.
Adopt centrifugal casting technology, under high rotating speed operating on centrifugal force, the material of nichrome batching is more tight.The complete use of float grease seal, one to be arranged on floating sealing base relatively static, another is arranged in ground-engaging element, accurate two sphere grinding techniques are used in the rubber seal of O shape, can utilize the lubricant oil in the parts die cavity to play uniform wear, the effect of compensation, also can effectively prevent outside silt mutually, the intrusion of sewage, can reach more than 4000 hours working life.
the above, it is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
