Abstract
The invention discloses a kind of bearing spill retainer, including left ring, right ring, connector, cone is recessed, Zuo Huan, right ring is shape identical annular, Zuo Huan, uniform design has shape identical cone recessed respectively on right ring, Zuo Huan, conical recessed opening on right ring is relative, relative conical recessed concave bottom point line is vertical with bearing rotation direction, connector one end be fixedly connected on the cone of left ring two it is recessed between midpoint on, the other end be fixedly connected on the cone of right ring two it is recessed between midpoint on, the upper conical concave bottom portion of retainer is that point contacts with taper rolling element conical points.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 spill 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 spill retainer low, vibrations are small.
In order to achieve the above object, the present invention adopts the technical scheme that：A kind of bearing spill retainer, including left ring,
Right ring, connector, cone are recessed, and Zuo Huan, right ring are shape identical annular, and it is tangible to distinguish uniform design on Zuo Huan, right ring
Shape identical cone is recessed, and the conical recessed opening on Zuo Huan, right ring is relative, relative conical recessed concave bottom point line and axle
Hold that rotation direction is vertical, connector one end be fixedly connected on the left cone of ring two it is recessed between midpoint on, the other end is fixedly connected
On midpoint between the right cone of ring two is recessed, the upper conical concave bottom portion of retainer contacts with taper rolling element conical points for point.
The connector is cylinder or segment.
The recessed cone is 3-200.
The recessed opening taper of the cone is 20-170 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, recessed using two tapers of retainer, is precisely controlled the rolling of rolling element, and with rolling
Kinetoplast, bearing inner race, outer ring keep gap, the point contact of retainer are realized in structure, also using spring promotion activity
Circular cone is recessed, makes retainer keep appropriate strength to contact with rolling element all the time, so as to more be precisely controlled the rolling of rolling element, from structure
On realize low-frictional force, 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.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is use state sectional view of the present invention.
