Abstract

The utility model discloses a novel bearing with a sealed spherical surface and relates to the technical field of bearings. The novel bearing comprises an outer ring (1), multiple rolling bodies (2), an inner ring (3) and three-lip seal devices (4), wherein the inner ring (3) is arranged in the outer ring (1) in a sleeving manner; the rolling bodies (2) are arranged between the outer ring (1) and the inner ring (3); a three-lip seal device (4) is arranged between each of two side of the outer ring (1) and the inner ring (3) and is composed of a three-layer blocking seal ring (41) and a dustproof hood (42) wrapping the outer wall of the blocking seal rings (41). The novel bearing with the sealed spherical surface is simple in structure and good in sealing performance; internal lubricating oil is effectively prevented from leaking out; the lubricating effect is guaranteed and the service life of the bearing is prolonged.

Description

A kind of novel sealing bearing with spherical outside surface

Technical field:

The utility model relates to technical field of bearings, is specifically related to a kind of novel sealing bearing with spherical outside surface.

Background technique:

The reason of bearing early failue has a variety of, as bad in Rig up error, lubrication effect etc., requiring the occasion of bearing seal, the sealability of bearing plays a key effect, at the applied roller bearing units of agricultural machinery industry because of its special working environment, high to seal request performance, poor sealing performance, foreign matter easily enters bearing inside, infringement bearing channel precision, affect bearing usability, make bearing premature failure.

The spherical bearing of conventional seals form, because of the restriction of its seal form, does not have the dust-proof effect of expectation, has not reached client's usage requirement.

Model utility content:

The purpose of this utility model is to provide a kind of novel sealing bearing with spherical outside surface, and it is simple in structure, and good seal performance has also effectively prevented the excessive of internal lubrication oil, has guaranteed lubrication effect, has improved the life-span of bearing.

In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises outer ring 1, rolling element 2, inner ring 3 and three lip seal devices 4; Inner ring 3 is set in outer ring 1, and between outer ring 1 and inner ring 3, be provided with several rolling elements 2, between the both sides of outer ring 1 and inner ring 3, be provided with three lip seal devices 4, three described lip seal devices 4 are comprised of three obstruction seals circles 41 and dust-proof cover 42, and dust-proof cover 42 is packaged in the outer wall of three obstruction seals circles 41.

The utlity model has following beneficial effect: it is simple in structure, good seal performance, has also effectively prevented the excessive of internal lubrication oil, has guaranteed lubrication effect, has improved the life-span of bearing.

Accompanying drawing explanation:

Fig. 1 is the utility model structural representation;

Fig. 2 is the A portion enlarged view in Fig. 1.

Embodiment:

Referring to Fig. 1 and Fig. 2, this embodiment by the following technical solutions: it comprises outer ring 1, rolling element 2, inner ring 3 and three lip seal devices 4; Inner ring 3 is set in outer ring 1, and between outer ring 1 and inner ring 3, be provided with several rolling elements 2, between the both sides of outer ring 1 and inner ring 3, be provided with three lip seal devices 4, three described lip seal devices 4 are comprised of three obstruction seals circles 41 and dust-proof cover 42, and dust-proof cover 42 is packaged in the outer wall of three obstruction seals circles 41.

This embodiment has following beneficial effect: it is simple in structure, and good seal performance has also effectively prevented the excessive of internal lubrication oil, has guaranteed lubrication effect, has improved the life-span of bearing.
