Abstract
The utility model relates to a bearing seal structure which comprises a seal ring and an inner ring groove, wherein the seal ring is provided with a main lip, an inner lip and an outer lip; the inner ring groove is provided with a lip edge; the main lip and the lip edge are in contact seal; and the inner lip and the outer lip are respectively in clearance labyrinth seal with the inner ring groove. By adopting two non-contact lips and one contact lip, the bearing seal structure has a small contact pressure and a good seal effect.
Description
Technical field
The utility model relates to a kind of sealing configuration, a kind of specifically bearing seal structure.
Background technique
Sealed bearing structure design problem on the market is bigger now, and sealing effect is bad, and leakage fat phenomenon is more serious, and the user has strong complaints.Through analyzing, main cause is that existing seal ring project organization is unreasonable, add accuracy of manufacturing not the plateau because of causing.
Summary of the invention
The utility model is intended to overcome the defective of existing technology, and a kind of bearing seal structure is provided, and adopts two non-contact lips and a contact-type lip, and contact pressure is little, good sealing effect.
In order to solve the problems of the technologies described above, the utility model is achieved in that
A kind of bearing seal structure comprises seal ring and interior ring recess, and it is characterized in that: seal ring is provided with main lip, epipharynx and outer lip, and interior ring recess is provided with the lip limit, and main lip and lip limit are contact seal; Epipharynx, outer lip are the gap labyrinth seal with interior ring recess respectively.
The beneficial effect of the utility model is: tightness is strong, easy to use, the life-span is long; The internal diameter of the seal ring lip adopts many lips formula; Many lips play the multiple protective effect; Fat groove between many lips and interior ring recess and seal groove constitute the storage of pressure buffer and lubricating grease, and the effect that has retardance lubricating grease to leak has increased sealing effect.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is done further to specify:
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1: a kind of bearing seal structure, comprise seal ring 1 and interior ring recess 2, seal ring 1 is provided with main lip 14, epipharynx 12 and outer lip 15, and interior ring recess 2 is provided with lip limit 21, and main lip 14 is contact seal with lip limit 21; Epipharynx 12, outer lip 15 are the gap labyrinth seal with interior ring recess 2 respectively.
The main lip 14 of seal ring, epipharynx 12 and outer lip 15 have formed contact-type and contactless combination, and it has the following advantages:
Many places sealing between seal ring 1 and the interior ring recess 2, main lip 14 is contact seal with lip limit 21; Epipharynx 12, outer lip 15 are the gap labyrinth seal with interior ring recess 2 respectively.
The inner lip of epipharynx 12 can prevent that bearing internal lubrication fat from directly outwards spilling; If the bearing internal grease is excessive, hinder lip place through gap 3 in main lip 14, can improve sealability.
The lip position of main lip 14 contacts with the lip limit 21 of seal ring and forms contact seal, improves sealability and stable friction torque.
The outer lip position of outer lip 15 helps to prevent dust because action of centrifugal force gets into bearing inside.
This structure adopts two non-contact lips and a contact-type lip, and contact pressure is little, good sealing effect.
