Description
Technical field
The present invention relates to bearing arrangement, more particularly to a kind of point contact type bearing arrangement.
Background technology
Before bearing development wrinkle shape can be traced to several dry years, there have been rolling bearing for the Qin Dynasty of B.C. more than 200 years
Wrinkle shape.C. watts of Lip river of 17th century Britain devises ball bearing, the fertile patents for thinking to achieve ball bearing of p., John Harry in 1760
The inferior practical rolling bearing for carrying retainer of input earliest, Friedrich Fei Sheer in 1883 are proposed using suitable production
The production standard of machine and rolling bearing, using this trade mark of FAG and used till today to application in 1962.Henry iron in 1895
Mu Ken designs first taper roll bearing and obtains patent, has set up Timken companies.SKF bearings factory in 1907
Polite temperature Qwest devises earliest modern self-regulated heart ball bearing.
Retainer at present has metal, plastics etc., and retainer and rolling element contact area are big, cause
Frictional force is big, and easy heat production, noise is big, and vibrations are big, directly influence bearing high-speed cruising and service life.
The content of the invention
The present invention is in order to overcome with the shortcomings that upper bearing (metal) and deficiency, there is provided a kind of frictional force is small, heat production is few, noise is low, shake
Dynamic small point contact type bearing.
In order to achieve the above object, the present invention adopts the technical scheme that：
A kind of point contact type bearing, including taper rolling element, spill retainer, inner ring, outer ring, inner ring, outer ring set for annular
Meter, inner ring are contained in outer ring center, with keeping uniform gap on the inside of outer ring on the outside of inner ring, the body portion one side of taper rolling element with it is interior
Circle outside contacts, body portion another side and outer ring inner faces contact, the upper conical concave bottom portion of spill retainer and the taper of taper rolling element
The tapering of rolling element contacts for point.
The taper rolling element, including body portion and tapering, tapering are cone, and tapering is separately fixed at the two of body surface
Side, the cone in tapering is outside, and the cone in two taperings and the center in body portion are point-blank.
The body portion is spherical or cylindrical or the dumbbell bodily form or circle rhombohedreon shape or double sphericals or double round rhombohedreon shapes.
The spill retainer, including：Zuo Huan, right ring, conical recessed, connector, Zuo Huan, right ring design are that shape is identical
Annular, uniform design has shape identical cone recessed respectively on Zuo Huan, right ring, and conical on Zuo Huan, right ring recessed is opened
Mouth is relative, and relative conical recessed concave bottom portion line is vertical with bearing rotation direction, and cone is recessed less than boring, and connector is cylinder
Shape or segment, connector one end be fixedly connected on the cone of left ring two it is recessed between midpoint on, the other end is fixedly connected on the right side
On midpoint between the cone of ring two is recessed, the inner ring with bearing, outer ring and taper rolling element do not contact connector, connector and axle
There is gap between the inner ring, outer ring and the taper rolling element that hold.
A kind of point contact type bearing, including：Spill rolling element, taper retainer, inner ring, outer ring, inner ring, outer ring are annulus
Shape designs, and inner ring is contained in outer ring center, and inner ring outside is with keeping uniform gap, the body portion one side of spill rolling element on the inside of outer ring
With being contacted outside inner ring, the body portion another side of spill rolling element and outer ring inner faces contact, on taper retainer cone it is sharp with it is recessed
The recessed base point contact of two tapers of shape rolling element.
The spill rolling element, including：Body portion and tapering, tapering are cone, and tapering is fixed in the both sides in body portion, cone
The cone in portion is inside, and formation taper is recessed, and the taper concave bottom portion in two taperings and the center in body portion are point-blank.
The body portion is spherical or cylindrical or the dumbbell bodily form or circle rhombohedreon shape or double sphericals or double round rhombohedreon shapes.
The taper retainer, including：Zuo Huan, right ring, connector, cone point, Zuo Huan, right ring design are that shape is identical
Annular, even respectively on Zuo Huan, right ring to be designed with shape identical cone point, the cone point on Zuo Huan, right ring, point
Portion is relative, and the tip line of relative two cone points is vertical with bearing rotation direction, and cone is less than cone nest, and connector is cylinder
Shape or segment, connector one end are fixedly connected on the midpoint between the left cone of ring two point, and the other end is fixedly connected on the right side
On midpoint between the cone point of ring two, the inner ring with bearing, outer ring and spill rolling element do not contact connector, connector and axle
There is gap between the inner ring, outer ring and the spill rolling element that hold.
It can also be separately designed on the left ring, right ring and get rid of oilhole, beneficial to the lubrication of high-speed bearing.
The present invention has abandoned Traditional Thinking, is precisely controlled the rolling of rolling element using the bullet on retainer, and with rolling
Kinetoplast, bearing internal external circle keep gap, the point contact of retainer are realized in structure, also using spring promotion activity circular cone
Shape is recessed or conical points make retainer keep appropriate strength to contact with rolling element all the time, so as to more be precisely controlled the rolling of rolling element,
Low-frictional force, low vibrations, low yield heat, low noise, low bearing wear, long life are realized from structure.
Compared with the prior art, the invention has the advantages that：
1. the present invention has abandoned Traditional Thinking, retainer is contacted with the face of rolling element and has made into a little to contact, so as to cut axle
The friction between retainer and rolling element is held, reduces bearing noise, reduces bearing vibrations.
2. retainer is set to keep appropriate strength to connect with rolling element all the time using the conical recessed or conical points of spring promotion activity
Touch, so as to more be precisely controlled the rolling of rolling element, low-frictional force is realized from structure, low vibrations, low yield is warm, and low noise is low
Bearing wear, long life.
3. the left ring of the present invention, right ring have dust cap function concurrently, bearing can not separately make dust cap.
4. structure of the present invention further simplifies, production process is reduced, and cost reduces.
5. the present invention can high-speed cruising, service life length, suitable for various machineries.
