Abstract
The utility model relates to a sealing element, in particular to an oil seal with a dust cover. The oil seal comprises a rubber body and a framework and is characterized in that an outward flange of the oil seal is provided with the structure of a dust cover and an end-surface axial limiting flange is arranged on the positioning end surface on which the oil seal is in contact with a seat hole. The contact position between the end of the dust cover and a half axle is arranged at the contact position between the outer circle of the end R of the dust cover and the outer circle of the half axle R. The contact position between the end of the dust cover and a dust-blocking disc is provided with the structure of the outward flange. The horizontal plane of the outward flange at the end of the dust cover is higher than that of the dust-blocking disc of the half axle. Therefore, during working, through the positioning of the contact end surface between the oil seal and the seat hole, the outer circle of the end R of the dust cover can be in effective contact with the outer circle of the half axle R, thereby preventing dust and foreign matters from entering sealing parts of the oil seal and a bearing. Moreover, the horizontal plane of the outward flange at the end of the dust cover is higher than that of the dust-blocking disc of the half axle, which can effectively prevent muddy water from entering the sealing parts of the oil seal and the bearing when an automobile runs on a road in rainy days.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of oil sealing with dust-proof cover.
Background technique
Present oil sealing mainly is to contact with the cylindrical place of axle half shafts R by long secondary lip to stop that outside dust, impurity enter oil sealing sealing position and bearing, but self is spacing because oil sealing when assembling can not be axially, if crossing to have assembled to make the cylindrical place of long secondary lip and axle half shafts R not reach, thereby advance the dirt phenomenon, can make long secondary lip contact excessive generation wearing and tearing with the cylindrical place of axle half shafts R and owe to assemble; In addition because the secondary lip of length of oil sealing and the cylindrical place contacting point horizontal plane of axle half shafts R are lower than semiaxis dust blocking tray horizontal plane, then when automobile when the rainwater road conditions are travelled, muddy water can enter oil sealing sealing position and bearing.As seen, the original structure oil sealing is not satisfactory because of the effect of its anti-dust, impurity and anti-muddy water, and its sealing is relatively poor, make that maintenance is frequent and workload is big, and its working life is short, damages easily, if cause changing untimely then can quicken the wearing and tearing of bearing.
The model utility content
The purpose of this utility model has been to propose a kind of oil sealing with dust-proof cover, and the oil sealing sealing of this structure is good, and anti-dust, impurity reach the effective of anti-muddy water, are convenient to maintenance, long service life.The technological scheme that the utility model adopted is:
A kind of oil sealing with dust-proof cover comprises rubber body and skeleton, it is characterized in that its outward flange is provided with dust cover structure.
The oil sealing of described band dust-proof cover, it is provided with the end face axial defining flange with contacted oil sealing location, seat hole end face.
The oil sealing of described band dust-proof cover, its dust-proof cover is terminal to be located at the cylindrical place of the terminal R of dust-proof cover and the cylindrical place touching position of axle half shafts R with the axle half shafts contacting point.
The oil sealing of described band dust-proof cover, its dust-proof cover is terminal to be provided with the outward flange structure with the dust blocking tray contacting point.
The oil sealing of described band dust-proof cover, the outward flange horizontal plane of its dust-proof cover end is higher than semiaxis dust blocking tray horizontal plane.
When work,, the cylindrical place of the terminal R of dust-proof cover is effectively contacted with the cylindrical place of axle half shafts R, thereby prevent that dust, impurity from entering oil sealing sealing position and bearing like this by the end face location that oil sealing contacts with the seat hole; The outward flange horizontal plane of dust-proof cover end is higher than semiaxis dust blocking tray horizontal plane in addition, can prevent effectively that then automobile muddy water when the rainwater road conditions are travelled from entering oil sealing sealing position and bearing.
The oil sealing of band dust-proof cover of the present utility model is prevented the satisfactory for result of dust, impurity and anti-muddy water, and its sealing is better, makes that maintenance is frequent and workload is little, and its long service life, is not easy to damage, and has reduced the wearing and tearing of bearing effectively.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is former oil sealing scheme of installation.
Fig. 2 is the oil sealing scheme of installation of the utility model band dust-proof cover.
Among the figure, 1 is rubber body, and 2 is skeleton, and 3 is outward flange, and 4 is the seat hole, and 5 are oil sealing location end face, and 6 is the end face axial defining flange, and 7 is the cylindrical place of the terminal R of dust-proof cover and the cylindrical place touching position of axle half shafts R, and 8 is dust blocking tray, and 9 is semiaxis.
Embodiment
Embodiment
As Fig. 1, shown in Figure 2, a kind of oil sealing with dust-proof cover comprises rubber body 1 and skeleton 2, and its outward flange 3 is provided with dust cover structure; It is provided with end face axial defining flange 6 with seat hole 4 contacted oil sealing location end faces 5; Its dust-proof cover is terminal to be located at the cylindrical place of the terminal R of dust-proof cover and the cylindrical place touching position 7 of axle half shafts R with the axle half shafts contacting point; Its dust-proof cover is terminal to be provided with the outward flange structure with dust blocking tray 8 contacting points, and the outward flange horizontal plane of dust-proof cover end is higher than semiaxis 9 dust blocking trays 8 horizontal planes.
When work,, the cylindrical place of the terminal R of dust-proof cover is effectively contacted with the cylindrical place of axle half shafts R, thereby prevent that dust, impurity from entering oil sealing sealing position and bearing like this by the end face location that oil sealing contacts with seat hole 4; The outward flange horizontal plane of dust-proof cover end is higher than semiaxis 9 dust blocking trays 8 horizontal planes in addition, can prevent effectively that then automobile muddy water when the rainwater road conditions are travelled from entering oil sealing sealing position and bearing.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all mode of executions.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
