Abstract

The utility model discloses a bearing sealing ring. The bearing sealing ring comprises a body and a steel framework, wherein the outer diameter end of the body is shaped like an arc, an upper lip, a middle lip and a lower lip are arranged at the inner diameter end of the body, the upper lip, the middle lip and the lower lip are connected into a whole, the section of the upper lip is shaped like oblique teeth, and the sections of the middle lip and the lower lip are shaped like the arcs. The bearing sealing ring has a good sealing effect through the contact type lower lip and the non-contact type upper lip and middle lip.

Description

A kind of bearing sealed ring

Technical field

The utility model relates to a kind of seal ring, especially a kind of bearing sealed ring.

Background technique

That bearing sealed ring is mainly used to is grease proofing, waterproof, corrosion protection gas, leakage-preventing, the sealing in the bearing now generally divides two kinds of the seal ring of contact-type and contactless seal rings, though contactless seal ring starting torque is little, but sealability is bad, leaks grease easily; The seal ring of contact-type only contacts with bearing inner race by single contact lip, and its sealability has narrow limitation.

The model utility content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of bearing sealed ring of good sealing effect is provided.

For achieving the above object, the technical solution of the utility model is: a kind of bearing sealed ring, comprise body and Steel Skeleton, the external diameter termination of described body is circular-arc, described body internal diameter end is provided with upper lip, middle lip and lower lip, described upper lip, middle lip and lower lip three are connected as a single entity, and the cross section of described upper lip is the helical teeth shape, and the cross section of described middle lip and lower lip is circular-arc.

The beneficial effects of the utility model are: by the lower lip of contact-type and contactless upper lip and middle lip, good sealing effect.

Description of drawings

Fig. 1 is installed in schematic representation on the bearing for the utility model;

Fig. 2 is schematic representation of the present utility model;

Fig. 3 is the enlarged view at A place among Fig. 1;

Fig. 4 is the bearing outer ring schematic representation.

Among the figure: body 1, external diameter termination 11, upper lip 12, middle lip 13, lower lip 14, Steel Skeleton 2, bearing outer ring 3, sealed groove 31, bearing inner race 4, inner ring shoulder outer surface 41, inner ring shoulder inclined-plane 42.

Embodiment

Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of bearing sealed ring, comprise body 1 and Steel Skeleton 2, the external diameter termination 11 of described body 1 is circular-arc, described body 1 internal diameter end is provided with upper lip 12, middle lip 13 and lower lip 14, described upper lip 12, middle lip 13 and lower lip 14 threes are connected as a single entity, and the cross section of described upper lip 12 is the helical teeth shape, and the cross section of described middle lip 13 and lower lip 14 is circular-arc.

The external diameter termination 11 of body 1 is fastened in the sealed groove 31 of bearing outer ring 3 internal surfaces, install firmly, inner ring shoulder inclined-plane 42 interference fit of lower lip 14 and bearing inner race 4, strengthened sealability, prevent that extraneous dust impurity grease from entering bearing inside, middle lip 13 cooperates with inner ring shoulder inclined-plane 42 non-contacts of bearing inner race 4, and upper lip 12 cooperates with inner ring shoulder outer surface 41 non-contacts of bearing inner race 4, middle lip 13 and upper lip 12 form labyrinths, have further promoted sealing effect.

Claims

1. bearing sealed ring, comprise body (1) and Steel Skeleton (2), it is characterized in that: the external diameter termination (11) of described body (1) is for circular-arc, described body (1) internal diameter end is provided with upper lip (12), middle lip (13) and lower lip (14), described upper lip (12), middle lip (13) and lower lip (14) three are connected as a single entity, the cross section of described upper lip (12) is the helical teeth shape, and the cross section of described middle lip (13) and lower lip (14) is circular-arc.
