Abstract
The invention discloses a kind of bearing funnel retainer, including left ring, right ring, connector, conical point, Zuo Huan, right ring design is shape identical annular, Zuo Huan, uniform design has shape identical cone point respectively on right ring, Zuo Huan, the tip of cone point on right ring is relative, the line of relative cone point is vertical with bearing rotation direction, connector is cylinder or segment, the streamlined design that direct-axis holds rotation direction advantageously reduces wind and made an uproar, connector one end is fixedly connected on the midpoint between the left cone of ring two point, the other end is fixedly connected on the midpoint between the right cone of ring two point, the tip of conical point contacts with taper rolling element taper concave bottom point.The present invention, which contacts retainer with the face of rolling element, have been made into a little to contact, and so as to cut the friction between retainer and rolling element, reduces bearing noise, reduces bearing vibrations.
Description
Technical field
The present invention relates to bearing arrangement, more particularly to a kind of bearing funnel retainer device.
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 shortcomings that present invention is in order to overcome above retainer and deficiency, there is provided a kind of frictional force is small, heat production is few, noise
Bearing funnel retainer low, vibrations are small.
In order to achieve the above object, the present invention adopts the technical scheme that：A kind of bearing funnel retainer, including left ring,
Right ring, connector, cone point, Zuo Huan, right ring design are shape identical annular, distinguish uniform design on Zuo Huan, right ring
There is shape identical cone sharp, the tip of the cone point on Zuo Huan, right ring is relative, the line and axle of relative cone point
It is vertical to hold rotation direction, connector advantageously reduces wind for cylinder or segment, the streamlined design that direct-axis holds rotation direction
Make an uproar, connector one end is fixedly connected on the midpoint between the left cone of ring two point, and the other end is fixedly connected on the right circular cone of ring two
On midpoint between shape point, the tip of cone point contacts with taper rolling element taper concave bottom point.
The cone point is 3-200.
The taper of the cone point is 20-160 degree.
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, and the rolling of rolling element is precisely controlled using two conical points of retainer, and with rolling
Kinetoplast, bearing inner race, outer ring keep gap, the point contact of retainer are realized in structure, so as to more be precisely controlled rolling element
Rolling, realize low-frictional force from structure, low vibrations, low yield heat, low noise, low bearing wear, the long life.
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. the left ring of the present invention, right ring have dust cap function concurrently, bearing can not separately make dust cap.
3. structure of the present invention further simplifies, production process is reduced, and cost reduces.
4. the present invention can high-speed cruising, service life length, suitable for various machineries.
