Abstract
The utility model relates to a sealed bearing used for decreasing friction. The sealed bearing used for decreasing the friction comprises an outer frame, a holder, a quill roller and sealing rings, wherein the holder is installed inside the outer frame, the quill roller is arranged on the holder, the sealing rings are installed inside the outer frame on both sides of the holder, and a lip is installed on the inner wall of each sealing ring. The sealed bearing used for decreasing the friction is characterized in that a U-shaped groove is installed on the lip on the inner wall of each sealing ring. The sealed bearing used for decreasing the friction has the advantages that blocking force can be reduced and the friction between the sealing rings and a core shaft can be reduced when the sealed bearing is in an assembling process.
Description
Technical field
The utility model relates to a kind of stuffing box bearing, relates in particular to a kind of stuffing box bearing that can reduce friction.
Background technique
Present stuffing box bearing comprises outer ring, retainer, needle roller and seal ring, wherein retainer is installed in the outer ring, needle roller is installed on the retainer, seal ring is installed in the outer ring of retainer both sides, inwall at seal ring has a lip, thus so that the drag that stuffing box bearing produces on being installed to mandrel the time is larger, the assembling of stuffing box bearing brings difficulty, simultaneously stuffing box bearing when mandrel moves seal ring without the non-displacement amount, be easy to produce friction and cause wearing and tearing with mandrel, can produce axle burn phenomenon when serious.
Summary of the invention
For above-mentioned shortcoming, can reduce drag when the purpose of this utility model is to provide a kind of the assembling and can lower the stuffing box bearing that can reduce friction of the friction of seal ring and mandrel.
Technology contents of the present utility model is: a kind of stuffing box bearing that can reduce friction, comprise outer ring, retainer, needle roller and seal ring, wherein retainer is installed in the outer ring, needle roller is installed on the retainer, seal ring is installed in the outer ring of retainer both sides, at the inwall of seal ring one lip is arranged; It is characterized in that being provided with a U-shaped groove at the lip of seal ring inwall.
The advantage that the utility model compared with prior art has is: be provided with a U-shaped groove by the lip at the seal ring inwall, the drag that stuffing box bearing produces on being installed to mandrel the time is less; When mandrel during in axial displacement, U-shaped groove axially have certain displacement amount can for the seal ring lip, avoids seal ring and mandrel the dry friction phenomenon to occur, improves the seal ring of mandrel and the working life of axle.
