Abstract
The utility model relates to an oil seal, in particular to an oil seal with an embedding function. The oil seal with the embedding function comprises an oil seal framework (1). A circular bump (2) is arranged at the bottom end of the oil seal framework (1). A groove (3) is formed between the side face of the circular bump (2) and the bottom face of the oil seal framework (1). The top end of the oil seal framework (1) bends inward to form a fold (4) which corresponds to the groove (3) in shape. For the improved oil seal, as a mutually embedded structure is added, the oil sealed unassembled can be assembled integrally, so that damage of the oil seal caused by malposition of original common oil seals during press fitting can be avoided.
Description
Technical field
The utility model relates to a kind of oil sealing, relates in particular to a kind of oil sealing with chimeric function.
Background technique
Rotary shaft lip seal is commonly called as oil sealing, is mainly used in sealing between the parts that relatively rotate, and prevents that the lubricant oil of machinery inside from leaking.Improve sealing reliability or more abominable in external environment at needs, needing to strengthen can increase an oil sealing in the situation of dust-proof effect usually, assembles simultaneously two oil sealings to reach needed sealing effect or dust-proof effect.Assembling two oil sealings should need to carry out twice assembling, but when actual state is assembling, normally two stacked disposable holes that are pressed into of oil sealing.Because two oil sealings are just simply stacked, when being pressed into, if just put not or run-off the straight in the process of press in, dislocation occurs between the oil sealing easily causes oil sealing to be crushed out of shape, cause oil sealing to damage.
The model utility content
Technique effect of the present utility model can overcome defects, and a kind of oil sealing with chimeric function is provided, and it has improved sealing effect.
For achieving the above object, the utility model adopts following technological scheme: it comprises oil tight skeleton, the bottom of oil tight skeleton is provided with annular protrusion, form groove between the side of annular protrusion and the bottom surface of oil tight skeleton, the top of the oil tight skeleton formation flanging that bends inwards, the shape of flanging is corresponding with groove.
Oil sealing after the improvement has increased an annular protrusion with certain outer incline angle in the bottom surface, the outer incline angle with respect to oil tight skeleton axially between the 20-30 degree.The indent degree of depth of groove is 0.5-1mm.
Oil sealing after the improvement owing to having increased can be mutually chimeric structure, can be assembled into oil sealing an integral body, thereby can be effectively to avoid original common oil sealing because the oil sealing damage that occurs each other to misplace and cause press-fiting before assembling.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that two oil sealings are used in combination view.
Among the figure: 1. oil tight skeleton; 2. annular protrusion; 3. groove; 4. flanging.
Embodiment
As shown in Figure 1, oil sealing with chimeric function of the present utility model comprises oil tight skeleton 1, the bottom of oil tight skeleton 1 is provided with annular protrusion 2, form groove 3 between the bottom surface of the side of annular protrusion 2 and oil tight skeleton 1, the top of oil tight skeleton 1 bends inwards and forms flanging 4, and the shape of flanging 4 is corresponding with groove 3.
As shown in Figure 2, when two oil sealings of needs assembling, can with the annular protrusion of outer side seal and the recess space tabling of interior side seal, make its one-tenth as a whole.Then use frock, a disposable hole that is pressed into.
Certainly, when not needing to use two oil sealing sealings, the oil sealing after the improvement also can be used as the monomer oil sealing and uses, on its sealing effect without any impact.
Claims (3)
1. oil sealing with chimeric function, comprise oil tight skeleton (1), it is characterized in that, the bottom of oil tight skeleton (1) is provided with annular protrusion (2), form groove (3) between the bottom surface of the side of annular protrusion (2) and oil tight skeleton (1), the top of oil tight skeleton (1) bends inwards and forms flanging (4), and the shape of flanging (4) is corresponding with groove (3).
2. the oil sealing with chimeric function according to claim 1 is characterized in that, annular protrusion (2) is obliquely installed.
3. the oil sealing with chimeric function according to claim 2 is characterized in that, annular protrusion (2) angle of inclination axial with respect to oil tight skeleton is 20-30 °.
