Abstract
The utility model provides a bearing outer ring, belonging to the technical field of machinery; the bearing outer ring solves the problems that the existing bearing outer ring has infirm stress point, and the stress intensity is insufficient. The inner wall of the outer ring of the bearing is circumferentially provided with a roller path which is used for a rolling body to roll, and the outer wall of the bearing outer ring is provided with conical degree, the diameter of one end of the outer wall of the bearing wall is less than the diameter of the other end; the bearing outer ring has firm stress point and good stress intensity, and the sealing property is good.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of bearing outer ring, particularly a kind of stressed intensity enhancing, the bearing outer ring that force bearing point is firm.
Background technique
At present, its basic structure of the bearing of selling on market is made up of outer ring, inner ring, one group of rolling element and retainer.The appended part of this bearing supporting Internal and external cycle carries out relative movement and bears certain radial load and axial load, to the firm requirement of the intensity of bearing enclose and force bearing point than higher.But the outer diameter at two, outer ring that present bearing is used is identical, and when installing and using this bearing on some machinery, the force bearing point that can cause bearing is not very firm, is subjected to the yet not enough problem of force intensity.
Summary of the invention
The purpose of this utility model is at the above-mentioned problems in the prior art, has proposed a kind of can effectively the raising and has been subjected to force intensity, and can make the bearing outer ring of force bearing point firm stable.
The purpose of this utility model can realize by following technical proposal: a kind of bearing outer ring, circumferentially be provided with the raceway that rolls for rolling element on this bearing outer ring inwall, it is characterized in that the outer wall of described bearing outer ring has tapering, the outer wall one end diameter of this bearing outer ring is less than the other end diameter.
Because an end diameter of the outer wall of this bearing outer ring is less than the diameter of the other end, when bearing active force, active force can be along the tapering effect of outer ring outer wall, only be subjected to the component effect of active force like this at the bearing outer ring axial direction, component is littler than active force, and the outer ring outer diameter of common bearing is the same, just directly bears whole active forces, so under same active force, the bearing strength of this outer ring has obtained reinforcement.When bearing active force, the outer diameter difference of this bearing outer ring can make force bearing point firm stable more simultaneously.
In above-mentioned bearing outer ring, described raceway is near the less end of outer diameter of bearing outer ring.The end wall that the outer ring outer diameter is big is thick like this, can further improve the soundness of shaft strength point.
In above-mentioned bearing outer ring, inwall two of described bearing outer ring is circumferentially with one deck step one respectively.In the step one seal ring can be installed, the bearing seal that makes bearing outer ring and inner ring, rolling element, retainer assembly like this is guaranteed.
In above-mentioned bearing outer ring, the inwall of the long correspondence of described bearing outer ring outer diameter is provided with one deck step two.Be installed in the seal ring of this end, further improved the sealability of bearing, the performance oil-proof, dust protection that the bearing that makes installation form has is more remarkable.
In above-mentioned bearing outer ring, described bearing outer ring outer wall and bearing outer ring both ends of the surface joint are respectively equipped with tangent cambered surface.Transition between the outer wall of outer ring and the upper and lower end face is very smooth like this, has increased the aesthetic property of bearing outer ring.
In above-mentioned bearing outer ring, described groove-section is a circular arc.The raceway of circular arc has guaranteed the fluency of rolling element when rolling.
In above-mentioned bearing outer ring, described rolling element is a ball.
Compared with prior art, designed the step of multilayer installation seal ring on the inwall of this bearing outer ring, further improved the sealability of bearing, it is more remarkable to make it performance oil-proof, dust protection.And outer ring outer wall has certain tapering, improved the soundness of the force bearing point of the bearing of forming being installed by it, is subjected to force intensity also to obtain enhancing.
Description of drawings
Fig. 1 is a kind of axial section schematic representation of this bearing outer ring when being unkitted seal ring.
Fig. 2 is a kind of elevational schematic view of this bearing outer ring.
Among the figure, 1, raceway; 2, step one; 3, step two; 4, cambered surface; 5; Rolling element.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
Embodiment one
As depicted in figs. 1 and 2, the outer wall of this bearing outer ring has certain tapering, that is to say, the diameter of outer wall one end of this bearing outer ring is less than the diameter of the other end.Circumferentially be provided with the raceway 1 of circular arc at bearing outer ring on inwall, raceway 1 is near the less end of outer diameter of bearing outer ring, and rolling element 5 can roll in raceway 1, and rolling element 5 is a ball.
Inwall two at bearing outer ring is circumferentially with one deck step 1 respectively, and the inwall of the long correspondence of bearing outer ring outer diameter is provided with one deck step 23.Step 1 and step 23 all can be installed seal ring.Seal ring on the installation step 1 can be so that the bearing seal that bearing outer ring and inner ring, rolling element 5, retainer assembly be guaranteed.Be installed in the seal ring on the step 23, further improved the sealability of bearing, the performance oil-proof, dust protection that the bearing that makes installation form has is more remarkable.
Be respectively equipped with tangent cambered surface 4 at bearing outer ring outer wall and bearing outer ring both ends of the surface joint.Transition between the outer wall of outer ring and the upper and lower end face is very smooth like this, has increased the aesthetic property of bearing outer ring
Because an end diameter of the outer wall of this bearing outer ring is less than the diameter of the other end, when bearing active force, active force can be along the tapering effect of outer ring outer wall, only be subjected to the component effect of active force like this at the bearing outer ring axial direction, component is littler than active force, and the outer ring outer diameter of common bearing is the same, just directly bears whole active forces, so under same active force, the bearing strength of this outer ring has obtained reinforcement.And when bearing active force, the outer diameter difference of this bearing outer ring can make force bearing point firm stable more.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as raceway 1, step 1, step 23, cambered surface 4, rolling element 5 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
