Description
Technical field
The present invention relates to bearing arrangement, the device of more particularly to a kind of bearing spill retainer with thrust.
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
Low, the small bearing spill retainer with thrust of vibrations.
In order to achieve the above object, the present invention adopts the technical scheme that：A kind of bearing spill retainer with thrust, bag
It is recessed to include left ring, right ring, connector, cone, activity is conical recessed, and Zuo Huan, right ring are shape identical annular, left ring or the right side
Uniform design has shape identical cone recessed on ring, and uniform design has the activity of shape identical conical on left ring or right ring
Recessed, cone is recessed relative with movable cone is recessed recess, and opposed recesses line is vertical with bearing rotation direction, connector one end
Be fixedly connected on left ring or the cone of right ring two it is recessed between midpoint on, the other end is fixedly connected on left ring or the activity circle of right ring two
On midpoint between taper is recessed.
The activity cone is recessed to include cylinder groove, the conical recessed, spring of activity, and cylinder groove is cylinder or square column type
Or elliptical cylinder-shape design, shape identical cylinder groove, the recessed system of activity cone are designed with left ring or right ring or left ring, right ring
The cylinder being adapted with cylinder groove shape or square column type or elliptical cylinder-shape are made, left ring or right ring or a left side are connected to by spring
Ring, in the cylinder groove on right ring, spring one end is fixed on cylinder trench bottom, and the spring other end is fixedly connected with the conical concave bottom of activity
Portion, spring make movable cone is recessed can be moved up and down in cylinder groove, and spring makes the recessed recess of movable cone all the time with suitable
When strength and taper rolling element conical points apexes contact.
The left ring or right ring or left ring, the outer rim of right ring are further fixed on annulus, and connector passes through from left ring or right ring,
It is fixed on annulus, spring one end is fixed on annulus, and the spring other end is fixedly connected on the outside of left ring or right ring, and spring makes
Right ring or left ring can move on connector.Spring makes the conical recessed concave bottom portion on right ring or left ring all the time with appropriate forces
Degree contacts with rolling element tapering point.
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, using the recessed rolling for being precisely controlled rolling element of two tapers of retainer, and with rolling
Kinetoplast, bearing inner race, outer ring keep gap, and the point contact of retainer is realized in structure, utilizes spring promotion activity circular cone
Shape is recessed to make retainer keep appropriate strength point 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. retainer is set to keep appropriate strength to contact with rolling element all the time using spring promotion activity cone is recessed, so as to more
The rolling of rolling element is precisely controlled, low-frictional force is realized from structure, low vibrations, low yield is warm, low noise, 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.
