Abstract
The utility model relates to a waterproof bearing, comprising an inner ring, an outer ring, a retainer, steel balls and a waterproof sealing ring. The points of the design are as follows: two ends of the waterproof sealing ring are respectively provided with a first arc groove and a second arc groove. The other end of the waterproof sealing ring is provided with a sealing ring cone and a sealing end surface; wherein the sealing right cone is shaped like a transverse V and is sleeved into the inner ring along the diametral plane of the inner ring, thereby a first sealing effect is achieved; the sealing end surface is of a W shape, two sealing points are in interference-fit with a horizontal concave edge of the inner ring to have a second sealing effect and a third sealing effect; and the third sealing effect guarantees that the bearing has better sealing effect. By the elasticity of an elastic skeleton in the waterproof sealing ring and the second arc groove and the first arc groove of the waterproof sealing ring, the waterproof sealing ring is in interference-fit between the inner ring and the outer ring. The utility model has the advantages of simple structure, convenient assembly and good sealing performance, and is particularly suitable for a dune buggy with good water proof effect.
Description
Technical field
The utility model relates to a kind of water-sealed bearing.
Background technique
As everyone knows, bearing is that mechanical industry is used extensive, strict auxiliary equipment and basic part, is called " joint " of machinery by people.Because bearing plays the effect of back shaft, leading axle rotation in machinery, be widely used in the mechanical main frame of every field such as industry, agricultural, national defence, science and technology and household electric appliance, has diversity and complexity.Bearing is assemblied in the associated mechanical main frame, and its quality and performance directly influence the proper functioning of mechanical main frame.
Bearing is as the auxiliary equipment and the basic part of precision, and most of bearing materials adopt steel, as are assemblied in the associated mechanical main frame, work under water environment, are easy to cause the corrosion of bearing inside, causes precision, stability to reduce, and shorten working life.In order to make the bearing can be in proper functioning under the water environment, the outside of some bearings be provided with various water-proof protection devices, makes it prolong the working life of bearing.But the structure of most water-proof protection devices is comparatively complicated, and assembling is inconvenience comparatively, and cost of production is higher relatively.
Summary of the invention
For overcoming above-mentioned deficiency, purpose is to provide a kind of sealing configuration simple water-sealed bearing to related domain, makes it solve the existing not good enough technical problem of water-sealed bearing sealing effect.The purpose of this utility model is to adopt following technological scheme to realize.
A kind of water-sealed bearing, this bearing comprise inner ring, outer ring, are arranged between the inside and outside circle and by the steel ball that retainer is located, are respectively equipped with waterproof grommet between the inside and outside circle in bearing both sides that be provided with elastic skeleton in the waterproof grommet, an end is provided with sealing cone.Its key points in design is that the waterproof grommet two ends are respectively equipped with first curve bath and second curve bath.The waterproof grommet the other end is provided with sealing right cone and seal face, and the sealing right cone is " ∠ ", and the sealing right cone is inserted in inner ring along the diametric plane of inner ring, plays the effect of first road sealing; Seal face is " W ", and the horizontal concave edge interference fit of two seal points and inner ring plays the effect of second and third road sealing, and this three seals has guaranteed that bearing has the better seal effect.By the elastic force of elastic skeleton in the waterproof grommet, and second curve bath of waterproof grommet, first curve bath, sealing cone, the waterproof grommet interference fit is between inside and outside circle.
Described outer ring is provided with the taper concave edge, and inner ring is provided with horizontal concave edge.
The taper concave edge of the sealing cone of described waterproof grommet and outer ring fastens.
Of the present utility model have simple in structurely, easy to assembly, and the characteristics of favorable sealing property are particularly useful for the mechanical main frame under the water environment.

The sequence number of above accompanying drawing and title: 1, inner ring, 2, waterproof grommet, 21, sealing cone, 22, first curve bath, 23, the sealing right cone, 24, second curve bath, 25, seal face, 3, elastic skeleton, 4, the outer ring, 5, steel ball.
Embodiment
Mode of execution is an example with working principle of the present utility model.As shown in Figure 2, waterproof grommet 2 two ends are respectively equipped with first curve bath 22 and second curve bath 24, and inside is provided with elastic skeleton 3.
According to the bearing of different model, select different waterproof grommets for use.As shown in Figure 1, outer ring 4 is provided with the taper concave edge, and inner ring 1 is provided with horizontal concave edge.Waterproof grommet is inserted in cavity between bearing both sides inner ring and the outer ring respectively, and the sealing cone 21 of waterproof grommet one end inserts the taper concave edge of outer rings, the taper concave edge fastening of sealing cone and outer ring.The sealing right cone 23 of the waterproof grommet the other end is " ∠ ", and the sealing right cone inserts cavity between the inside and outside circle along the inner ring diametric plane; Seal face 25 is " W ", and two seal points are inserted in along the horizontal concave edge of inner ring, two seal points of seal face and the horizontal concave edge interference fit of inner ring.By the elastic force of elastic skeleton in the waterproof grommet, and sealing cone, first curve bath, second curve bath make the waterproof grommet interference fit between the inside and outside circle in bearing both sides, reaches the effect of sealing.
The waterproof grommet of original water-sealed bearing, shown in Fig. 3,4, it is relatively poor that this water-sealed bearing and waterproof grommet thereof and the utility model are compared sealing effect.The synthetic triple seal of two seal points of the seal point of " ∠ " portion of the utility model sealing right cone and " W " portion of seal face seals up the cavity between the inside and outside circle in water-sealed bearing both sides, reaches the waterproof and dustproof effect.
The utility model is reasonable in design, simple in structure, easy to assembly, triple seal is effective, the water that has guaranteed certain pressure is isolated in outside the water-sealed bearing, prevented that extraneous water, dust granule from entering water-sealed bearing inside, corrode or influence effective running of steel ball, make the mechanical main frame proper functioning that water-sealed bearing is housed.For example, water-sealed bearing is contained on the beach buggy, plays the excellent waterproof effect.
