Abstract
The utility model relates to a kind of deep groove ball bearing with oil-bearing structure, which includes outer ring, inner ring, rolling element, retainer, sealing element, and the outer ring raceway cooperated with rolling element is equipped in outer ring, and outer ring both ends of the surface are equipped with the seal groove cooperated with sealing element；Its structural feature is that the inner hole hole wall in the outer ring between seal groove and outer ring raceway is equipped with the annular retaining ring along inner hole radial protrusion.By the way that the annular retaining ring is arranged, when bearing runs at high speed, the problem of bearing grease is directly got rid of to sealing element inner surface is effectively reduced, form the effect of oil storage, to guarantee Bearing inner lubrication sufficiently, the stability of bearing applying working condition is improved, performance and used life is improved.
Description
Technical field
The utility model relates to bearings, are a kind of deep groove ball bearings with oil-bearing structure.
Background technique
Deep groove ball bearing is a kind of important spare part in contemporary mechanical equipment, its major function is the mechanical rotation of support
Body reduces the coefficient of friction in its motion process, and guarantees its rotating accuracy.Deep groove ball bearing is generally by outer ring, inner ring, rolling
Body, sealing element and four part of retainer composition.When bearing runs at high speed, it is easy lubricating grease being thrown to sealing element inner surface, from
And risk of the bearing there are premature failure is easily led to, influence the service life of bearing.Need thus to existing deep groove ball bearing
It improves.
Summary of the invention
To overcome above-mentioned deficiency, the purpose of this utility model is that a kind of deep-groove ball axis with oil-bearing structure is provided to this field
It holds, so that it is solved existing similar bearing lubricating grease and easily get rid of to sealing element inner surface, and bearing lubrication position is caused to lack lubrication, easily
The technical issues of leading to bearing premature failure, influencing service life.The purpose is to what is be achieved through the following technical solutions.
A kind of deep groove ball bearing with oil-bearing structure, the bearing include outer ring, inner ring, rolling element, retainer, sealing element,
The outer ring raceway cooperated with rolling element is equipped in outer ring, outer ring both ends of the surface are equipped with the seal groove cooperated with sealing element；Its structure is wanted
Point is that the inner hole hole wall in the outer ring between seal groove and outer ring raceway is equipped with the annular gear along inner hole radial protrusion
Circle.By the way that the annular retaining ring is arranged, when bearing runs at high speed, effectively reduces bearing grease and directly got rid of to table in sealing element
The problem of face, that is, the effect of oil storage is formed, to guarantee Bearing inner lubrication sufficiently, improves the stability of bearing applying working condition,
Improve performance and used life.
In the above-mentioned deep groove ball bearing with oil-bearing structure, the annular axle center of the annular retaining ring and the axle center of the outer ring exist
On same straight line, and annular retaining ring is the outer ring raceway relative to inner hole relative to the height dimension of the inner hole hole wall protrusion
The one third of the depth dimensions of hole wall indent is to 2/3rds.With this configuration, annular retaining ring is made to reach preferably gear oil, oil storage
Effect.
In the above-mentioned deep groove ball bearing with oil-bearing structure, there are following for the connection between the annular retaining ring and the outer ring
Three kinds of scenario-frames:
Scenario-frame one: the annular retaining ring is integrally formed with the outer ring.The structure is more reliable, stablizes.
Scenario-frame two: the inner hole hole wall of the outer ring is equipped with the annular caulking groove for being embedded in the annular retaining ring, annular retaining ring
It is caught in annular caulking groove.The structure facilitates processing, while facilitating annular retaining ring damage replacement.
Scenario-frame three: the inner hole hole wall of the outer ring is equipped with internal screw thread, the inner hole hole wall of the annular retaining ring and outer ring
Between be threadedly engaged.The structure has the effect of adjusting annular retaining ring in outer ring inner hole hole wall position, to realize preferably gear
Oil, oil storage effect.
The utility model overall structure is simple, preferable to lubricating grease gear oil, oil storage effect in bearing, guarantees the high revolving speed of bearing
The reliability of internal lubrication under operating condition effectively increases the stability that bearing uses, improves bearing performance and service life.Its
The deep groove ball bearing for being suitable as machinery field uses or the structure of similar bearing is improved.
