Abstract
This invention provides waterproof bearing. It includes outer ring, inner ring, steel ball and sealing ring. The steel balls are arranged between inner and outer ring. They are positioned by holding support. The sealing ring is arranged between inner and outer side rings. One end of sealing ring is assembled in the sealing groove of outer ring inner surface. The other end has two contacting lips. One lip cooperates with chamfering faces at outer surface both sides of inner ring. The other contacting lip cooperates with outer surface of inner ring. This invention makes the vapor or certain pressure water outside the bearing separate out of bearing. Thus, self waterproof can be achieved.
Description
Technical field
The present invention relates to a kind of bearing, particularly a kind of water-sealed bearing, the occasion that is mainly used in humidity, water pouring or has water to wash away.
Background technique
As everyone knows, the bearing of being made by bearing steel material drenches and has under the working environment that water washes away at moist, water, and moisture content is easy to enter the corrosion that bearing inside causes bearing inside, makes bearing failure, influences the working life of bearing.
For preventing can long-life proper functioning at the above-mentioned environment lower bearing that water arranged, people have made various protective equipments in the exterior design of bearing, but have both caused the complexity of structure like this, have also increased cost.
Summary of the invention
Goal of the invention: the objective of the invention is at the deficiencies in the prior art, a kind of simple in structure, water-sealed bearing that water-proof performance is good is provided.
Technological scheme: water-sealed bearing of the present invention, comprise outer ring, inner ring, be arranged between the Internal and external cycle and by the steel ball of retainer location, it is characterized in that between the Internal and external cycle both sides, being respectively equipped with seal ring, one end of sealing circle is installed in the seal groove of inner surface, the other end has two contact lips, an one contact lip closely cooperates with the chamfer surface that is arranged on inner ring outer surface both sides, and another contact lip cooperates with the outer surface of inner ring.
Seal ring is generally made by flexible materials such as rubber, therefore, in order to increase the intensity of seal ring, is provided with rigid backbone in seal ring.
Described seal ring and outer ring do not have relative movement, and relative movement is arranged with inner ring, therefore the sealing effect between seal ring and the inner ring is very important, the present invention is arranged to two independently surface of contact with the seal face between seal ring and the inner ring, and on the chamfer surface of inner ring and on the outer surface, when bearing bore external pressure, the contact lip that contacts with the chamfer surface of inner ring can more be adjacent to chamfer surface respectively, its protective ability is stronger, has improved sealed waterproof effect greatly.In order further to improve sealing effect, between seal ring and the inner ring interference fit.
Beneficial effect: the present invention compared with prior art, its significant advantage is to have formed a Seal cage by seal ring between inner ring, outer ring, the steam of bearing outside or the water of certain pressure are isolated in the bearing outside, and can not enter bearing inside, realized the function of self waterproof, and simple in structure, waterproofing effect is fine.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the partial enlarged drawing of band chamfer site among Fig. 1.
Embodiment
The water-sealed bearing of the present invention design is made up of outer ring 1, inner ring 2, one group of steel ball 3, retainer (containing rivet) 4, seal ring 5, and one group of steel ball 3 is installed between the Internal and external cycle by retainer.Seal ring 5 is made by rubber material, and its inside is provided with the skeleton 10 that " L " shape metallic material is made.1 internal surface both sides are provided with o-ring groove in the outer ring, are provided with chamfering in the both sides of the outer surface of inner ring, and this chamfering is best with the circular arc chamfering, in addition, also can be arc angling, perhaps straight line chamfering.Two seal rings are installed between the Internal and external cycle respectively.One end of seal ring is installed in the seal groove of outer ring, and the other end is provided with two contact lips 6 and 7, respectively with the outer surface 9 and chamfer surface 8 interference fit of inner ring 2.Seal ring and outer ring do not have relative movement, have relative movement with inner ring.
When bearing bore external pressure (hydraulic pressure), the contact lip that contacts with the chamfer surface of inner ring can more be adjacent to chamfer surface, and its protective ability is stronger.Excessive for preventing the friction torque of bearing when working, smooth treatment has all been carried out on the bearing inner race surface that contacts with the seal ring epipharynx.
