Abstract
The utility model discloses a sealing structure of a bearing outer ring, which comprises an annular sealing rolling passage and a sealing baffle ring, wherein the annular sealing rolling passage is formed on the inner surface of the bearing outer ring, the sealing baffle ring is fixedly arranged in the bearing outer ring and corresponds to the annular sealing rolling passage, the sealing baffle ring consists of an annular elastic sealing ring and a framework, and the cross section of the annular sealing rolling passage is in a V-shaped structure. Because the cross section of the annular sealing rolling passage of the bearing outer ring is changed from a trapezoidal structure into the V-shaped structure, the cut size of the bearing outer ring is reduced, and the rigidity of a bearing is improved. Thereby, the bearing outer diameter change is small after a dustproof cover is arranged on the bearing, and the condition of outer diameter deformation of the bearing outer ring can be greatly reduced. In addition, the service life of the bearing is also greatly prolonged, and the service life of products can be prolonged.
Description
Technical field
The utility model relates to a kind of associated sealing arrangement for bearings, is specifically related to the sealing configuration of bearing outer ring.
Background technique
Bearing is a kind of important base components that is widely used in all kinds of machineries, is used for bearing load and makes rotation, swing or linear reciprocating motion.As shown in Figure 1, bearing mainly is made of inner ring 2, outer ring 1, rolling element 4, retainer 9 and Sealing 8, and inner ring is installed on the axle usually and rotates together with the axis; The outer ring play supporting role in bearing support or in the mechanical part housing usually; Rolling element rolls between inner ring and outer ring, and its size and quantity directly influence the bearing capacity of bearing; Retainer is with one group of rolling element spaced at equal intervals in the bearing, and the guiding rolling element moves on correct track, improves the bearing internal load and distributes and greasy property.The Sealing role is; Sealing prevents that grease leakage and introduced contaminants, moisture from entering bearing.
The sealing configuration of existing bearing is by the caulking gum outer lip, and man type epipharynx and steel plate web frame three parts are formed.Wherein: outer lip and the lasso groove radial interference fit of preventing dust, jump out to prevent Sealing.The main lip of man type epipharynx and secondary lip and inner ring interference fit prevent that grease from leaking; The Sealing skeleton plays reinforing function.As shown in Figure 2, the age of a draught animal 7-1 near end face in the sealing configuration of existing bearing outer ring is a trapezium structure, because the trapezium structure space is too big, it is too much that bearing outer ring is cut, and causes the rigidity loss of bearing big; (existing dust cover is the circular cowling structure after its fitted with dust caps, usually be stamped to form by metal sheet, be fixed on the lasso or packing ring of bearing, and towards another lasso or packing ring extension, cover the inner space of bearing), the bearing outside diameter variation is too big, causes the external diameter distortion defective, and influences the normal use of bearing.
At present, also do not solve the problems of the technologies described above better technological scheme.
The model utility content
The purpose of this utility model is to overcome the problems referred to above that exist in the background technique, and a kind of improvement of sealing configuration of bearing outer ring is provided, and the sealing configuration of this bearing outer ring should have simple and reasonable, novel in design; Bearing outer ring on it has that rigidity intensity is big, product qualified rate is high and the characteristics of long service life.
The utility model proposes following technological scheme:
A kind of sealing configuration of bearing outer ring comprises the annular seal raceway that is formed at the bearing outer ring internal surface, be fixedly arranged in the bearing outer ring and with the corresponding Sealing shield ring of annular seal raceway; Described Sealing shield ring is to be made of the elastic seal ring of ring-type and skeleton, it is characterized in that: the cross section of described annular seal raceway is " V " type structure.
The notch of described " V " type groove outwardly.
The cross section of described elastic seal ring is " V " type structure.
The beneficial effects of the utility model are: because the cross section of bearing outer ring annular seal raceway changes V-structure into by trapezium structure, the volume that bearing outer ring is cut reduces, and has improved the rigidity of bearing; The bearing outside diameter variation is little when making its fitted with dust caps, has improved bearing outer ring external diameter distortion situation widely; In addition, also improve widely the working life of bearing.Improved the working life of product.
Description of drawings
Fig. 1 is the structural representation of existing bearing.
Fig. 2 is the sectional structure enlarged view of Fig. 1 middle (center) bearing outer ring annular seal raceway.
Fig. 3 is the bearing structure schematic representation after the utility model improves.
Fig. 4 is the sectional structure enlarged view of Fig. 3 middle (center) bearing outer ring annular seal raceway.
Embodiment
Below, the technical solution of the utility model is described further by Figure of description.
Shown in Fig. 3,4, a kind of sealing configuration of bearing outer ring comprises the annular seal raceway 5 that is formed at bearing outer ring 3 internal surfaces, and seal ring 6 is installed on the annular seal raceway 5, the outer rim of described seal ring is an elastomer, and interference fit is formed on the bottom of this elastomer and annular seal raceway.Improvement of the present utility model is: the cross section of described annular seal raceway 5 is " V " type structure." V " type of being somebody's turn to do sealing raceway 5 is bigger than brearing bore near the age of a draught animal 7 of end faces.Change V-structure into by the cross section with bearing outer ring annular seal raceway, the volume that bearing outer ring is cut reduces, and has improved the rigidity of bearing; The bearing outside diameter variation is little when making its fitted with dust caps, has improved bearing outer ring external diameter distortion situation widely; In addition, also improve widely the working life of bearing.Improved the working life of product.
As improvement of the present utility model, the cross section of described seal ring is " V " type structure.
Described bearing outer ring is the tubulose circle body, and the place, aperture, axis hole two ends in the circle body is rounded down; Described annular seal raceway is arranged on the internal surface of bearing outer ring along the direction of axis line of bearing outer ring.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can not depart from spirit of the present utility model or surmount the defined scope of appended claims.
Claims (3)
1. the sealing configuration of a bearing outer ring, comprise the annular seal raceway (5) that is formed at bearing outer ring (3) internal surface, seal ring (6) is installed on the annular seal raceway (5), and the outer rim of described seal ring is an elastomer, and interference fit is formed on the bottom of this elastomer and annular seal raceway; It is characterized in that: the cross section of described annular seal raceway (5) is " V " type structure.
2. the sealing configuration of bearing outer ring according to claim 1 is characterized in that: described " V " type sealing raceway, its age of a draught animal (7) near end face is bigger than brearing bore.
