Abstract
The utility model relates to a seal ring, belonging to the seal piece, comprising a frame and a rubber seal body, wherein the rubber seal body is clad on the excircle surface of the frame, therefore an external seal body is formed and at least three seal lips are arranged on the inner side surface of the seal ring contacting with the rotation axle along the axial direction and in interference fit with the rotation axle and the direction of each seal lip is same. The seal ring has features of simple structure, small start moment, convenient assembly, good seal effect and high reliability.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of oil sealing.
Background technique
Component such as the motor of existing automobile, motorcycle and vehicle bridge need dustproof and sealing lubricating oil in a few thing environment, be used for the seal configuration more complicated of motor and vehicle bridge at present, need bigger moment of torsion during startup.But in some actual working environment, require seal configuration simple, be convenient to assembling, and have less starting torque, therefore existing Sealing can not meet the demands.
The model utility content
The purpose of this utility model is to have proposed a kind of seal ring, and it is simple in structure, and starting torque is little, and is easy to assembly, good sealing effect, reliability height.
The utility model is to adopt following technological scheme to realize: a kind of seal ring, form by skeleton and rubbery sealed body, wherein, rubbery sealed body is coated on the outer peripheral surface of skeleton, thereby form the outside seal body, the inner side surface upper edge that seal ring contacts with running shaft is axially arranged with at least three sealing lips, is interference fit between sealing lip and the running shaft, and the direction of each sealing lip is identical.
According to the form and the mounting type in fitting seat hole, the outer side surface of outside seal body can be the plane, also can have ripple.
The beneficial effects of the utility model are: at first, compare with existing oil sealing, the sealing circle need not to be provided with spring, reduces the parts of oil sealing, and assembling is simple, has reduced cost of production; Secondly, externally under the acting in conjunction of seal and sealing lip, sealing effect is better, the reliability height; In addition, packing lubrication oil can reduce the wearing and tearing of lip in the space of sealing lip and running shaft, reduces starting torque, has prolonged the working life of oil sealing.
Description of drawings
Fig. 1 is a half sectional view of the present utility model.
Embodiment
As shown in Figure 1, the sealing circle is made up of skeleton 1 and rubbery sealed body, on the outer peripheral surface of rubbery sealed body coating and skeleton 1, thereby form outside seal body 4, according to the form and the mounting type in fitting seat hole, the outer side surface of outside seal body 4 can be the plane, also can have ripple.The inner side surface upper edge that seal ring contacts with running shaft is axially arranged with three seals lip 2, be interference fit between sealing lip 2 and the running shaft, and the direction of three sealing lips is identical, sealing lip can seal dust and grease effectively, therefore externally under the acting in conjunction of seal 4 and sealing lip 2, sealing effect is better for the sealing circle.Compare with existing oil sealing, the sealing circle need not to be provided with spring, reduces the parts of oil sealing, and assembling is simple, has reduced cost of production.In addition, sealing lip can be provided with three, also can be provided with more than three, but the direction of each sealing lip is identical.
When three sealing lips 2 with after running shaft contacts, form two accumulators 3 between sealing lip and the running shaft, in accumulator 3, smear lubricating grease before the assembling, can reduce the wearing and tearing of oil seal lip, the minimizing starting torque, thereby prolonged working life of seal ring.
Claims (2)
1. seal ring, form by skeleton and rubbery sealed body, it is characterized in that: rubbery sealed body is coated on the outer peripheral surface of skeleton, thereby form the outside seal body, the inner side surface upper edge that seal ring contacts with running shaft is axially arranged with at least three sealing lips, be interference fit between sealing lip and the running shaft, and the direction of each sealing lip is identical.
2. seal ring according to claim 1 is characterized in that: the outer side surface of described outside seal body has ripple.
