Abstract
The utility model relates to a seal element, in particular to a reed-free framework type oil seal which comprises a framework and a seal lip in interference fit with a rotating shaft, wherein the bottom end surface of the oil seal is provided with at least one annular end surface seal rib. The reed-free framework type oil seal has a simple structure, and simultaneously realizes radial sealing and end surface sealing, thus greatly improving the sealing effect of the oil seal.
Description
Technical field
The utility model relates to a kind of Sealing, the skeleton oil sealing of especially a kind of no spring.
Background technique
At present, the structure of no spring formula outside framework oil seal is as depicted in figs. 1 and 2, and wherein Fig. 1 does not have spring formula outside framework oil seal for single lip, promptly comprises a sealing lip in the oil sealing; Fig. 2 does not have spring formula outside framework oil seal for lips, promptly comprises two sealing lips in the oil sealing.Sealing lip has played the effect of packing grease.The defective that the oil sealing of this structure exists is: axial float can take place in running shaft at work, and lubricating grease is very easily revealed from the end face of oil sealing in the axial motion process, causes the oil sealing leakage of oil.
The model utility content
The purpose of the utility model has been to propose a kind of skeleton oil sealing of no spring that has end face seal structure, and this oil seal structure is simple, has realized radial seal and end face seal simultaneously, has improved the sealing effect of oil sealing greatly.
The utility model is that the technological scheme below adopting realizes: the skeleton oil sealing of a kind of no spring comprises skeleton and is the sealing lip of interference fit with running shaft that wherein, the bottom end face of oil sealing is provided with the end face seal muscle of at least one annular.
In the utility model, described oil sealing comprises at least one sealing lip.
Described end face seal muscle can be continuous end face seal muscle, also can be for being interrupted the end face seal muscle of setting.
The beneficial effect of the utility model is: through the end face at oil sealing the end face seal muscle is set; Make oil sealing possess the double seal effect of radial seal and end face seal simultaneously; The end face that produces when preventing the running shaft axial float is revealed, and has improved the sealing effect of oil sealing greatly.
Description of drawings
Fig. 1 is the half sectional view that existing single lip does not have spring formula outside framework oil seal;
Fig. 2 is the half sectional view that existing lips do not have spring formula outside framework oil seal;
Fig. 3 is the half sectional view of the skeleton oil sealing of no spring in the utility model.
Among the figure: 1 sealing lip; 2 end face seal muscle; 3 skeletons.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 3 is the skeleton oil sealing of the described no spring of the utility model.This oil sealing comprises skeleton 3 and sealing lip 1, is coated with rubber body on the skeleton 3.This oil sealing comprises two sealing lips 1, is interference fit between the lip of sealing lip 1 and the running shaft, thereby prevents the lubricating grease leakage, makes sealing lip 1 play the effect of radial seal.Simultaneously, the bottom end face of oil sealing is provided with the end face seal muscle 2 of two annulars, in the assembly process, through pressed end face seal muscle 2, makes end face seal muscle 2 realize that the end face seal of oil sealing is axial seal.When running shaft in rotary course axial float took place, end face seal muscle 2 prevented that lubricating grease from revealing from the oil sealing end.Therefore, the oil sealing of this structure has the double seal effect of radial seal and axial seal.
End face seal muscle 2 is not limited to two shown in the figure, and the bottom end face of said oil sealing is provided with at least one end face seal muscle 2.Described each bar end face seal muscle 2 can be continuous shape setting, also can be and be interrupted the shape setting.In addition, the sealing lip in this oil sealing is not limited to two, also one or more sealing lips can be set.
Claims (3)
1. skeleton oil sealing of no spring comprises skeleton (3) and is the sealing lip (1) of interference fit with running shaft that it is characterized in that: the bottom end face of said oil sealing is provided with the end face seal muscle (2) of at least one annular.
2. the skeleton oil sealing of no spring according to claim 1 is characterized in that: described oil sealing comprises at least one sealing lip (1).
3. the skeleton oil sealing of no spring according to claim 1 is characterized in that: described end face seal muscle (2) is continuous end face seal muscle.
