Abstract
A kind of dual hump curved surface external diameter bearing outer ring with rib disclosed by the invention and the needle bearing for possessing the bearing outer ring, the positive camber of its dual hump curved surface external diameter bearing outer ring with rib is dual hump curve form；The dual hump curve form is made up of concave arc in two sections of shape identical evagination circular arcs and one section, and indent circular arc is between two sections of evagination circular arcs；The side of the interior raceway of the bearing outer ring is provided with rib.The bearing outer ring curved surface external diameter of the present invention forms compound dual hump curved surface using one section of evagination circular arc+interior concave arc+evagination circular arc, is equally coordinated with cage using envelope, make product by axial load also will not clamping stagnation in cage both sides, bearing capacity raising.The present invention is provided with rib in the side of the interior raceway of bearing outer ring, adds the intensity of bearing outer ring, reduces the deformation effect bearing life occurred because jump ring is pressed into outer ring.
Description
Technical field
The present invention relates to one kind for bear high intensity, full pin needle bearing that the motor turning of top load is saved, especially
It is related to a kind of dual hump curved surface external diameter bearing outer ring with rib and possesses the needle bearing of the bearing outer ring.
Background technology
Because needle bearing is simple in construction, large carrying capacity, structure type strong adaptability, precision and performance is continuous in addition
Improve, thus at home, outer various machineries, particularly in high-end vehicles equipment, the application of needle bearing is increasingly extensive, particularly
In some accurate process equipments and aircraft, make more and more widely in the drive system of superior automobile and motorcycle, steering
With this class bearing.
The external diameter of needle bearing coordinates with cage into envelope, and conventional external diameter is the curve form of certain curvature.Sphere needle roller
The repertoire of bearing is realized by rolling movement of the needle roller between inside and outside raceway, the bearing capacity of bearing and is made
It is decided by the transmission of power between needle roller and raceway with the life-span.The performance of needle bearing is improved, main target is needle roller to be reduced
With the contact of raceway, and it is set to be uniformly distributed as far as possible in contact area to give full play to material on whole contact area
Ability.
Needle bearing is all by 1 bearing outer ring 1,2 of bearing inner race 3,1 jump ring 4,5, the needle roller of varying number at present
6 form, and being covered with needle roller 6 has grease 2.Because jump ring material is spring steel, being attached to the jump ring after needle bearing has difference
The micro-strain of degree, during real-world operation, exist because needle roller is crooked and drive jump ring to rotate, using jump ring
Easily come off in journey, and then needle roller drops out, and makes product failure.Meanwhile using interference fit, axle between jump ring and outer ring jump-ring slot
External diameter is held after the press-in of outer ring, is easily deformed, after load is born, serious fragmentation failure occurs.And for external diameter, often go out
Now cause axial force bigger than normal because of abnormal stress, outer ring external diameter clamping stagnation is in cage both sides, so as to cause bearing capacity to weaken, life-span
It is short, premature failure, influence automobile and the personal safety of driver.
The content of the invention
An object of the present invention is to improve the bearing capacity of sphere needle bearing, is devised a kind of double with rib
Hump curved surface external diameter bearing outer ring.The bearing outer ring is reasonable in design, and bearing capacity is strong, and the life-span is high.
The second object of the present invention is to provide a kind of needle bearing for possessing above-mentioned bearing outer ring.
In order to solve the problems, such as techniques as described above, the present invention uses following technical scheme：
A kind of dual hump curved surface external diameter bearing outer ring with rib, it is characterised in that the positive camber of the bearing outer ring is
Dual hump curve form；The dual hump curve form is made up of concave arc in two sections of shape identical evagination circular arcs and one section,
Indent circular arc is between two sections of evagination circular arcs；The side of the interior raceway of the bearing outer ring is provided with rib.
In a preferred embodiment of the invention, two sections of evagination circular arcs are symmetrically positioned between the interior concave arc.
A kind of needle bearing with above-mentioned bearing outer ring, including above-mentioned bearing outer ring, bearing inner race and some needle rollers and
It is stuck in the jump ring of bearing outer ring opposite side, the needle roller is arranged on the outer of the interior raceway of above-mentioned bearing outer ring and the bearing inner race
Between raceway, the needle roller and the bearing inner race are also located between the rib and the jump ring.
As a result of design as above scheme, the invention has the advantages that：
1. the bearing outer ring curved surface external diameter of the present invention is compound using one section of evagination circular arc+interior concave arc+evagination circular arc composition
Dual hump curved surface, equally coordinated with cage using envelope, make product by axial load also will not clamping stagnation in cage both sides, carry energy
Power improves.
2. the present invention is provided with rib in the side of the interior raceway of bearing outer ring, the intensity of bearing outer ring is added, is reduced
The deformation effect bearing life occurred because jump ring is pressed into outer ring.
3. optimizing whole product structure, original bearing outer ring+bearing inner race+two panels jump ring+needle roller structure is optimized
For existing bearing outer ring+bearing inner race+a piece of clip spring structure with dual hump curved surface external diameter, original bilateral jump ring optimization
It is integrated in into unilateral jump ring, and by original side jump ring on bearing outer ring, thickeies bearing outer ring rib, bearing capacity carries
Height, reduce traditional bearing because rib is weak and caused by fragmentation fail, improve bearing service life.
