Abstract
The utility model discloses sealing pieces used for a cylindrical roller bearing. The nominal diameter of the inner diameter of an outer ring (5) is set as D, and the nominal diameter of the outer diameter of an inner ring (4) is set as d. Cylindrical rollers (3) are assembled on rolling paths corresponding to the outer ring and the inner ring through retaining frames (2). The sealing pieces (1) are respectively assembled on the inner diameter end face of the outer ring and the outer diameter end face of the inner ring, and are in a frame-shaped annular structure. The outer diameter of each sealing piece is matched with the nominal diameter D, and the interference magnitude is controlled between 0.05mm and 0.2mm. The inner diameter of each sealing piece is matched with the nominal diameter d, and the interference magnitude is controlled between 0.7mm and 0.95mm. The width of each sealing piece = [the width of the outer ring- the width of the rolling path of the outer rolling path] / 2. The sealing pieces adopt interference fit so that the sealing pieces can be firmly fixed on the outer ring. The interference fit and clearance fit of the sealing pieces are simultaneously carried out, and therefore sealing effects of the sealing pieces are guaranteed, assembly and disassembly of the sealing pieces are convenient, occasions with the sealing pieces needing frequently replacement can be adapted, and the sealing effects are good.
Description
Technical field
The utility model belongs to technical field of sealing technology, especially a kind of Sealing for roller bearing.
Background technique
Roller bearing is comprised of outer ring, inner ring, cylindrical roller and retainer usually, and rubber strip is generally adopted in the sealing of roller bearing end face or with the Sealing of steel plate frame, the rubber strip Sealing belongs to the gum material, therefore sealing intensity is lower; The steel plate frame Sealing is generally selected the fixed structure with the age of a draught animal, is not suitable for dismounting.
Summary of the invention
For addressing the above problem, the utility model has designed a kind of Sealing for roller bearing, the seal is frame shape loop configuration, the Sealing of frame shape loop configuration has higher intensity, be installed in the internal diameter end face of outer ring by interference fit, often need to be applicable to the occasion of replacing Sealing, sealing effect is good.
For achieving the above object, the utility model adopts following technological scheme:
A kind of Sealing for roller bearing, the nominal diameter of setting the outer ring internal diameter is D and the nominal diameter of inner ring external diameter is d, in the raceway corresponding with inner ring of outer ring, be equipped with cylindrical roller by retainer, also be equipped with Sealing at the internal diameter end face of outer ring and the external diameter end face of inner ring, Sealing is frame shape loop configuration, the external diameter of Sealing and described D mate but its magnitude of interference is controlled at 0.05~0.2 ㎜, the internal diameter of Sealing and described d mate but its gap is controlled at 0.7~0.95 ㎜, the width of Sealing=[outer ring width-outer ring raceway width] ÷ 2-surplus.
Above-mentioned Sealing or be made by metallic material, or be made by the high strength nonmetallic material.
Surplus described above is controlled at 0.5 ~ 2 ㎜.
Owing to adopting as mentioned above technological scheme, the utility model produces following beneficial effect:
1, the Sealing of frame shape loop configuration has higher support strength, and especially its support strength of Sealing of metallic material making is higher, and Sealing is more sturdy durable.
2, the internal diameter of the external diameter of Sealing and outer ring adopts interference fit, can make the Sealing of frame shape loop configuration firmly be fixed on the outer ring, and the external diameter of the internal diameter of Sealing and inner ring adopts Spielpassung, dual cooperation had both guaranteed the sealing effect of Sealing, be convenient to again assembling and the dismounting of Sealing, can satisfy frequent needs and change the occasion of Sealing, sealing effect is good.
Description of drawings
Fig. 1 is the structural representation sketch that Sealing is installed in the roller bearing end face.
Fig. 2 is the structural representation sketch of Sealing.
Among the above-mentioned figure: the 1-Sealing; The 2-retainer; The 3-cylindrical roller; The 4-inner ring; The 5-outer ring.
Embodiment
In conjunction with Fig. 1, the utility model is a kind of Sealing for roller bearing, and the nominal diameter of setting outer ring 5 internal diameters is D and the nominal diameter of inner ring 4 external diameters is d, is equipped with cylindrical roller 3 by retainer 2 in the corresponding raceway of outer ring 5 and inner ring 4.
Such as: described D=φ 200 ㎜, described d=φ 165.5 ㎜.
The external diameter end face of 5 internal diameter end face and inner ring 4 also is equipped with Sealing 1 in the outer ring, Sealing 1 is frame shape loop configuration, frame shape loop configuration as shown in Figure 2, the Sealing of frame shape loop configuration or be made by metallic material, or be made by the high strength nonmetallic material, thereby the Sealing of frame shape loop configuration has higher support strength, especially its support strength of Sealing of making of metallic material is higher, Sealing is more sturdy durable, but can't cause any damage to the outer ring.
The external diameter of Sealing 1 and described D=φ 200 ㎜ mate but its magnitude of interference is controlled at 0.05~0.2 ㎜, the internal diameter of Sealing 1 and described d=φ 165.5 ㎜ mate but its gap is controlled at 0.7~0.95 ㎜, the width of Sealing=[outer ring width-outer ring raceway width] ÷ 2-surplus, described surplus is controlled at 0.5 ~ 2 ㎜.Thickness to frame shape loop configuration Sealing is not done specific (special) requirements, and only otherwise the support strength that reduces Sealing gets final product, this support strength is at least greater than the support strength of steel plate frame Sealing.
Can find out by above-mentioned analysis: the external diameter of Sealing and the internal diameter of outer ring adopt interference fit, can make the Sealing of frame shape loop configuration firmly be fixed on the outer ring, and the external diameter of the internal diameter of Sealing and inner ring adopts Spielpassung, interference fit and Spielpassung start at the same time, both guaranteed the sealing effect of Sealing, be convenient to again assembling and the dismounting of Sealing, can satisfy the occasion that frequent needs are changed Sealing, sealing effect is good.
Claims (3)
1. Sealing that is used for roller bearing, the nominal diameter of setting outer ring (5) internal diameter is D and the nominal diameter of inner ring (4) external diameter is d, in outer ring (5) raceway corresponding with inner ring (4), be equipped with cylindrical roller (3) by retainer (2), it is characterized in that: the external diameter end face of the internal diameter end face of (5) and inner ring (4) also is equipped with Sealing (1) in the outer ring, Sealing (1) is frame shape loop configuration, the external diameter of Sealing (1) and described D mate but its magnitude of interference is controlled at 0.05~0.2 ㎜, the internal diameter of Sealing (1) and described d mate but its gap is controlled at 0.7~0.95 ㎜, the width of Sealing (1)=[outer ring width-outer ring raceway width] ÷ 2-surplus.
