Abstract
Needle bearing is saved in a kind of motor turning of dual hump curved surface external diameter disclosed by the invention, including bearing outer ring, bearing inner race and some needle rollers being arranged between the bearing inner race and bearing outer ring and the two panels jump ring being stuck between bearing outer ring, bearing inner race, two panels jump ring is located at needle roller both sides and needle roller is limited between the bearing inner race and bearing outer ring, characterized in that, the positive camber of the bearing outer ring is dual hump curve form.The positive camber that the bearing outer ring of needle bearing is saved in the motor turning of dual hump curved surface external diameter of the present invention is dual hump curve form, with cage using envelope coordinate, make product by axial load also will not clamping stagnation in cage both sides.Present invention optimizes whole product structure, original outer ring positive camber is optimized for into dual hump curved surface, product still retains original function, while bearing capacity improves, service life increase.
Description
Technical field
High intensity can be born the present invention relates to one kind, the full pin needle bearing that the motor turning of top load is saved, especially related to
And needle bearing is saved in a kind of motor turning of dual hump curved surface external diameter.
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, in the drive system of superior automobile and motorcycle, steering more and more widely
Use 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.Needle bearing
Repertoire be all to be realized by rolling movement of the needle roller between inside and outside raceway, the bearing capacity of bearing and use the longevity
Life is decided by the transmission of power between needle roller and raceway.The performance of needle bearing is improved, main target is needle roller to be reduced and rolling
The contact in road, and it is uniformly distributed as far as possible in contact area to give full play to the energy of material on whole contact area
Power.
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.Needle bearing in actual use, often occurs causing axial direction because of abnormal stress
Power is bigger than normal, and outer ring external diameter clamping stagnation is in cage both sides, so as to cause bearing capacity to weaken, short life, premature failure, influence automobile and
The personal safety of driver.
The content of the invention
The invention aims to improve the bearing capacity of sphere needle bearing, improve the uniformity of product carrying and set
Count a kind of motor turning of dual hump curved surface external diameter and save needle bearing.Rolling is saved in the motor turning of the dual hump curved surface external diameter
Needle bearing is reasonable in design, and bearing capacity is strong, and the life-span is high.
In order to solve the problems, such as techniques as described above, the present invention uses following technical scheme：
Needle bearing, including bearing outer ring, bearing inner race and arrangement are saved in a kind of motor turning of dual hump curved surface external diameter
Some needle rollers between the bearing inner race and bearing outer ring and the two panels card being stuck between bearing outer ring, bearing inner race
Spring, two panels jump ring are located at needle roller both sides and needle roller are limited between the bearing inner race and bearing outer ring, it is characterised in that described
The positive camber of bearing outer ring is dual hump curve form.
In a preferred embodiment of the invention, the dual hump curve form is by two sections of shape identical evagination circular arcs
With one section in concave arc composition, indent circular arc is between two sections of evagination circular arcs.
In a preferred embodiment of the invention, two sections of evagination circular arcs are symmetrically positioned between the interior concave arc.
As a result of technical scheme as above, needle bearing is saved in the motor turning of dual hump curved surface external diameter of the present invention
The positive camber of bearing outer ring is dual hump curve form, is coordinated with cage using envelope, product is not also blocked by axial load
It is stagnant in cage both sides.
Present invention optimizes whole product structure, original outer ring positive camber is optimized for into dual hump curved surface, product is still protected
Original function is stayed, while bearing capacity improves, service life increase.

Embodiment
Referring to Fig. 2 to Fig. 6, needle bearing is saved in a kind of motor turning of dual hump curved surface external diameter shown in figure, including
Bearing outer ring 70, bearing inner race 30 and some needle rollers 60 being arranged between bearing inner race 30 and bearing outer ring 70 and it is stuck in axle
Two panels jump ring 40,50 between bearing outer-ring 70, bearing inner race 30, two panels jump ring 40,50 are located at the both sides of needle roller 60 and limit needle roller 60
Between bearing inner race 30 and bearing outer ring 70, some needle rollers 60 are wrapped up system by grease 20.
It is a feature of the present invention that the positive camber of bearing outer ring 70 is dual hump curve form.Dual hump curve form by
Concave arc 73 forms in two sections of shape identical evagination circular arcs 71,72 and one section, interior concave arc 73 be located at two sections of evagination circular arcs 71,
Between 72.Two sections of evagination circular arcs 71,72 are symmetrically positioned between interior concave arc 73.
The positive camber that the bearing outer ring of needle bearing is saved in the motor turning of dual hump curved surface external diameter of the present invention is dual hump
Curve form, with cage using envelope coordinate, make product by axial load also will not clamping stagnation in cage both sides.Present invention optimizes
Whole product structure, original outer ring positive camber is optimized for dual hump curved surface, product still retains original function, while carries energy
Power improves, service life increase.
