Abstract
The utility model discloses a two-way seal ring for a bearing, which comprises an outer ring. A seal ring abuts against on the outer ring; a first sealing groove and a second sealing groove are axially arranged on the outer ring in sequence; and the seal ring is provided with a first sealing edge matched with the first sealing groove and a second sealing edge matched with the second sealing groove. In the two-way seal ring for the bearing, two layers of seals are provided; a buffering cavity is further arranged between the two layers of seals so that the sealing effect is better.
Description
Technical field
The utility model relates to a kind of seal ring, relates in particular to a kind of bearing two way sealed circle.
Background technique
The structure of oil-retaining bearing is often made by the inner lubricant grease that adds of roller bearing, and oil-retaining bearing resistance in rotation process is littler, rotates lighter.But lubricant oil tends to flow out in rotation process, and traditional way is the seal ring that adds on bearing as shown in Figure 1, but sealing effect is not good.
The model utility content
The utility model provides a kind of two way sealed circle of good sealing effect for solving the prior art problem.
The technical solution of the utility model is: a kind of bearing two way sealed circle, comprise the outer ring, there is seal ring on the top on this outer ring, be disposed with first seal groove and second seal groove on the described outer ring vertically, described seal ring is provided with first sealing strip that matches with first seal groove and second sealing strip that matches with second seal groove.
As preferably, the bottom of described first seal groove and second seal groove is not in the same plane.
As preferably, also be provided with buffer cavity between described first sealing strip and second sealing strip.
In sum, the utlity model has two-layer sealing, also be provided with buffer cavity between the two-layer sealing, sealing effect is better.
