Abstract
The utility model discloses three-lip bearing seal ring, which comprises a seal ring main body, wherein the central portion of the seal ring main body is provided with a hole which is matched with a shaft. The three-lip bearing seal ring is characterized in that one or a plurality of convex ring-shaped lips are distributed on the inner wall of the hole in space. The three-lip bearing seal ring adopts the lips with oblique angles to effectively prevent oil, steam and dust from entering a device along a shaft, which has simple structure, low production cost and excellent sealing effect, and can be used in hostile environment such as dust, dampness and high temperature.
Description
Technical field:
The utility model relates generally to a kind of bearing seal, relates in particular to a kind of bearing sealed ring that has the lip limit.
Background technique:
Leakage phenomenon is more frequent in the daily life.Usually, the leakage of manufacturing mechanism can cause the waste of material and the pollution of environment.Vapour in some environment, water, dust etc. are invaded the equipment pollution working medium, can aggravate the wearing and tearing of part, shorten life of equipment, even cause the inefficacy of work, so sealing effect needs to strengthen.
The model utility content:
The utility model purpose is exactly in order to overcome the defective of prior art, and a kind of bearing sealed ring that can effectively prevent vapour, water, dust along axle access arrangement inside is provided.
The utility model is achieved through the following technical solutions:
Three lip bearing sealed rings include the seal ring body, are the hole that cooperates with axle in the middle of the described seal ring body, it is characterized in that being intervally distributed with on the inwall of described hole the annular lip of one or more projectioies.
Described three lip bearing sealed rings is characterized in that described lip limit section is the oblique angle, and each lip limit is the direction unanimity at oblique angle.
Described bearing sealed ring is characterized in that described lip limit is three, is parallel to each other.
Dismounting is on axle easily for three lip bearing sealed rings, and the intrusion of the prevention vapour that three annular lip can be multiple, water, dust adds other media between the lip limit, and sealing effect is better.
The utility model has the advantages that:
The utility model adopts the lip limit of oblique angle shape can effectively stop water, vapour, dust along axle access arrangement inside, and is simple in structure, cost is low, good sealing effect, can use under the rugged environment of many dirt, humidity, high temperature.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
Three lip bearing sealed rings by seal ring body 1, have the annular lip 2 of three bevel shapes on the hole inwall of seal ring body and the end face that cooperates of axle.Lip limit 2 is an interference fit when cooperating with axle, and axle has relative motion with bearing sealed ring.
Claims (3)
1, three lip bearing sealed rings include the seal ring body, are the hole that cooperates with axle in the middle of the described seal ring body, it is characterized in that being intervally distributed with on the inwall of described hole the annular lip of a plurality of projectioies.
2, three lip bearing sealed rings according to claim 1 is characterized in that described lip limit section is the oblique angle, and each lip limit is the direction unanimity at oblique angle.
