Description
Technical field
The utility model relates to a kind of bearing, is specifically related to a kind of deep groove ball bearing.
Background technique
Bearing seal mainly in order to prevent the oiling agent of Bearing inner from leaking outside, and prevents outside moisture, dust, foreign matter etc. from entering Bearing inner, then affects runnability and the working life of bearing.A bearing for favorable sealing property, must possess under arbitrary cond, the feature that can operate safely and enduringly.But, often there is seal element and bearing fit too closely or the seal element defect of not easily taking out from bearing in the bearing that this sealability is higher.This also result in the inconvenience in time added oiling agent to Bearing inner or observe the normal operations such as the replacing of Bearing inner abrasion condition or Bearing inner rolling element or seal element self replacing.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of seal element and is easy to open, and bearing lubricant adds convenient, bearing part replacement deep groove ball bearing easily.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of deep groove ball bearing, comprise outer ring, inner ring, steel ball, retainer, inner ring is arranged in outer ring, steel ball is arranged on retainer, retainer is arranged between outer ring and inner ring, the internal surface at edge, outer ring is provided with the first groove, the outer surface at inner ring edge is provided with the second groove, seal element is provided with between first groove and the second groove, seal element comprises the seal ring mutually mated with the first groove and the second groove, seal ring is wholely set open portion, described open portion is connected with seal ring by joint.Embed and its seal ring mutually mated between the first groove and the second groove, the sealability that deep groove ball bearing is comparatively good can be realized.But, because seal ring is embedded between the first groove and the second groove, so generally, be difficult to directly seal ring be taken out.Deep groove ball bearing described in the utility model by being wholely set open portion on seal ring, and open portion is connected with seal ring by joint, when opening, only need to apply the power stretched out to by open portion to joint, being separated of seal ring and deep groove ball bearing can be realized, then can carry out the operations such as the replacing adding oiling agent or seal element in bearing.
As preferably, described seal element is made up of elastic material.
As preferably, the shape of described open portion is identical with seal ring.The open portion identical with seal ring shape, can facilitate the unlatching of seal element.
As preferred further, the distance between the outer ring of described open portion and inner ring is less than the distance between the outer ring of seal ring and inner ring.When distance between open portion outer ring and inner ring is less than the distance between seal ring outer ring and inner ring, can not have an impact to the assembling of bearing and other component.
As preferably, the radius of curvature of described inner ring raceway is 53 ~ 55% of steel ball size, and the radius of curvature of described outer ring raceway is 54% ~ 57% of steel ball size.The setting of the radius of curvature of the inner ring raceway in this limited range and the radius of curvature of outer ring raceway, makes the fatigue life of bearing, axial limit bearing capacity improve.
As preferably, described outer ring is provided with and is placed in the first annular baffle between the first groove and steel ball or inner ring and is provided with and is placed in the second annular baffle between the second groove and steel ball or outer ring is provided with the first annular baffle be placed between the first groove and steel ball, and inner ring is provided with the second annular baffle be placed between the second groove and steel ball.The setting of the first annular baffle, the second annular baffle, can avoid seal element to fall into Bearing inner due to External Force Acting, affect the normal operation of bearing.
As preferably, the thickness of revealing all the details of described retainer is 1.06-1.25mm.The ability to bear of thickness on bearing of retainer has larger impact.When the thickness of revealing all the details of retainer is 1.06-1.25mm, the intensity of retainer is higher, not easily produces comparatively serious damage when mutually clashing into.
The utility model compared with the existing technology has the following advantages and effect: 1, deep groove ball bearing described in the utility model has the seal element being easy to open, and makes to add the replacing of oiling agent or bearing component more for convenience to Bearing inner; 2, deep groove ball bearing described in the utility model defines the scope of the radius of curvature of inner ring raceway and the radius of curvature of outer ring raceway, the working life then extending bearing, the axial limit bearing capacity improving bearing; 3, the retainer intensity of deep groove ball bearing described in the utility model is higher, not easily in mutually colliding, produces damage.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
