Abstract
The utility model discloses a multi-lip seal ring with a framework used for a radial oscillating bearing. The seal ring is circular ring shaped, and is formed by positioning a metal framework 2 into the rubber body 1 of the seal ring, the cross section of the metal framework is right angle shaped, a section of one right angle side of the metal framework extends into the rubber body, the inner side of a section not extending into the rubber body is attached to the surface of the rubber body, the inner side of the other right angle side is also attached to the surface of the rubber body, and the metal framework 2 is attached to the vulcanized rubber body into a whole. The stability of the metal framework is good, so that the seal ring is not easy to deform. The sealing lip part 12 of the seal ring is designed into stepped multiple lips which can effectively prevent foreign bodies such as the dust from entering the working surface of the bearing, improving the cleanliness of the working surface of the bearing and reducing the abnormal abrasion of the working surface of the bearing, thereby prolonging the service life of the bearing.
Description
Technical field
The utility model relates to a kind of Sealing, specifically relates to a kind of plain radial bearing seal ring.
Background technique
Existing plain radial bearing seal ring is the homogenous material seal ring, and seal ring is a ring, is contained in plain radial bearing outer ring inner ball surface near the both ends of the surface position.The seal ring top is contained in the seal groove, and the seal ring rib abuts against on the seal groove rib, and the seal ring sealed lip is that a plane of inclination leans against on the plain radial bearing inner ring outer spherical surface, has only a lip.Therefore, sealing ring material not only to have and the joint shaft bearing outer ring between locating function (require material stiffness good), have again and joint shaft bearing inner ring outer spherical surface between the function (require elastic properties of materials good) of moving contact seal, and existing sealing ring material can't possess rigidity and flexible perfect unity.Existing sealing ring material causes the applying of sealed lip and sphere not tight because of rigidity compares easy deformation by force, and it is relatively poor to make foreign matter such as seal ring blocks dust enter the effect on bearing working surface.
The model utility content
The purpose of this utility model provides a kind of novel band skeleton mulit-lip seal ring, the sealing circle can overcome existing seal ring comparison easy deformation and stop that foreign matter etc. enters the relatively poor shortcoming of bearing working surface effect, improves the stability of existing seal ring and stops that foreign matter etc. enters the effect on bearing working surface.
The technological scheme that the utility model provides is: embed a circular ring metal skeleton in the rubber sealing ring body, the metal frame cross section is a right angle type, one section in right angle side of metal frame is stretched in the rubber body, the inboard of not stretching into interior one section of rubber body is attached on the rubber body surface, and the outside is as the back-up ring position of seal ring; The inboard of another right angle side also is attached on the rubber body surface, and metal frame and vulcanized rubber body are pasted and be one.The seal ring sealed lip is designed to stepped shaft simultaneously, makes the seal ring sealed lip have three places to contact with plain radial bearing inner ring outer spherical surface, forms three work lips, and forms dual mazy structure.
The beneficial effects of the utility model
Near the both ends of the surface position novel band skeleton mulit-lip seal ring is housed in plain radial bearing outer ring inner ball surface; the sealing circle has increased a circular ring metal skeleton; this metal frame has improved the stability of seal ring; the better rubber of elasticity is used; make seal ring be not easy distortion; simultaneously the seal ring sealed lip is designed to stepped shaft, and this stepped shaft has three places to contact with plain radial bearing inner ring outer spherical surface, plays multiple protective and prevents that foreign matter such as dust from entering the effect in the bearing working surface.Thereby improve the turbidity test on bearing working surface, reduce the heel and toe wear on bearing working surface, improve the working life of bearing.Sealed lip is designed to stepped shaft, has also reduced the surface friction drag between seal ring and the bearing inner race outer spherical surface, thereby improves the usability of bearing.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structure sectional view of the utility model band skeleton mulit-lip seal ring.
Fig. 2 is the another kind of mode of the structure sectional view of the utility model band skeleton mulit-lip seal ring.
Mark among the figure: 1-rubber sealing ring body, 2-metal frame, 11-seal ring top, 12-seal ring sealed lip, 21-backup ring position
Embodiment
Embodiment 1: as shown in Figure 1, the structure of the utility model band skeleton mulit-lip seal ring is a ring, comprises rubber sealing ring body 1, metal frame 2.Seal ring is contained in plain radial bearing outer ring inner ball surface near in the seal groove of both ends of the surface.Seal ring top 11 is contained in the seal groove, and backup ring position 21 abuts against on the seal groove circlip groove.Seal ring sealed lip 12 leans against on the plain radial bearing inner ring outer spherical surface, its special way is: be bumped into circular ring metal skeleton 2 in rubber sealing ring body 1, the metal frame cross section is a right angle type, one section in the right angle side of metal frame is stretched in the rubber body 1, rubber body is close in one section the right angle side inboard of not stretching in the rubber body, and the outside is as the back-up ring position 21 of seal ring; Another right angle side inboard of metal frame also is attached on the rubber body surface, metal frame 2 is pasted with vulcanized rubber body 1 and is one, seal ring sealed lip 12 is designed to stepped shaft, make the seal ring sealed lip have three places to contact, form three work lips with the plain radial bearing inner ring outer spherical surface of being adorned.
Embodiment 2: be illustrated in figure 2 as the utility model embodiment's another kind of mode, its structure is basic identical with embodiment 1, and just the sectional shape of rubber sealing ring body 1 and embodiment 1 have differently a little, and being contained in the interior rubber body 1 of seal groove does not have breach.
