Abstract
The utility model relates to an automobile bearing sealing device, and in particular relates to a framework oil seal. A convex-concave type framework oil seal comprises an outer edge, a framework, a main lip port and an auxiliary lip port, wherein an annular spring is arranged at the main lip port of the oil seal; and a mounting stress surface of the framework is of convex-concave type. According to the convex-concave type framework oil seal, the stress surface of the framework is of convex-concave type, so that the intensity of the framework is improved, and the oil seal cannot deform or rebound after being mounted; the concentricity of the main lip port of the oil seal and the shaft is guaranteed; a phenomenon of oil leakage is avoided; and the service life of the oil seal is prolonged.
Description
Technical field
The utility model relates to a kind of automobile bearing seal arrangement, especially a kind of outside framework oil seal.
Background technique
As shown in Figure 1, existing outside framework oil seal inner frame is designed to " L " formula, generally when mounted, hand-hydraulic, the assembling force bearing point of pounding when pressing are being installed stress surface 6 places, if firmly inhomogeneous when installing, force bearing point is easy to make product extrusion-deformation near secondary lip 5 places.If product is pressed and pounded distortion when installing, the main lip 4 of oil sealing can produce the phenomenon with the axle decentraction, oil leakage phenomenon, product failure will occur, influences the sealing reliability of product, thereby reduces the working life of product.
The model utility content
The purpose of this utility model is, a kind of improved outside framework oil seal is provided, and improves the installation reliability of oil sealing, increases the intensity of oil sealing, prolongs its working life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bump type outside framework oil seal, comprise outer rim, and skeleton, one main lip are with secondary lip; Main lip place at oil sealing is provided with annular spring; Installation stress surface on the skeleton is convex-concave.
Bump type outside framework oil seal of the present utility model because the stress surface of skeleton is designed to convex-concave, has increased the intensity of skeleton, make oil sealing indeformable after installation, do not rebound, guarantee the concentricity of main lip with the axle of oil sealing, avoided occurring oil leakage phenomenon, prolonged the working life of oil sealing.
Description of drawings
Fig. 1 is the structural representation of existing outside framework oil seal;
Fig. 2 is the structural representation of outside framework oil seal of the present utility model.
Embodiment
As shown in Figure 2, a kind of bump type outside framework oil seal comprises that outer rim 1 ', skeleton 2 ', one main lip 4 ' with secondary lip 5 ', are mainly used in preventing the leakage of lubricant oil; Main lip 4 ' at oil sealing locates to be provided with annular spring 3 '; Installation stress surface 6 ' on the skeleton 2 ' is convex-concave.
Claims (1)
1. a bump type outside framework oil seal comprises outer rim, and skeleton, one main lip are with secondary lip; Main lip place at oil sealing is provided with annular spring; It is characterized in that: the installation stress surface on the skeleton is convex-concave.
