Description

A kind of bearing funnel retainer with thrust

Technical field

The utility model is related to bearing arrangement, the device of more particularly to a kind of bearing funnel retainer with thrust.

Background technology

Before bearing development wrinkle shape can be traced to several dry years, there have been rolling bearings 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, and p. irrigates the patent for thinking to achieve ball bearing, John Harry in 1760 The inferior practical rolling bearing for carrying retainer of earliest input, 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 was 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.

Utility model content

The shortcomings that the utility model is in order to overcome more than retainer and deficiency, provide a kind of frictional force is small, heat production is few, Low noise, the small bearing funnel retainer with thrust of vibrations.

In order to achieve the above object, the technical scheme adopted by the utility model is that：A kind of bearing funnel with thrust is kept Frame, including left ring, right ring, connector, cone point, activity cone point, Zuo Huan, right ring are the identical circular ring shape of shape, left The cone that uniform design has shape identical on ring or right ring is sharp, and uniform design has the identical activity circle of shape on left ring or right ring Conical points, cone point is opposite with the tip of movable cone point, connector vertical with bearing rotation direction with respect to tip line One end is fixedly connected on the midpoint between two cone point of left ring or right ring, and the other end is fixedly connected on left ring or right ring two is lived On midpoint between dynamic cone point.

The conical point of activity includes cylinder groove, activity cone point, spring, and cylinder groove is cylindrical or square column type Or elliptical cylinder-shape design, the identical cylinder groove of shape, activity cone point system are designed on 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 sharp bottom of movable cone Portion allows movable conical point to be moved up and down in cylinder groove, and spring makes the tip of movable cone point always with appropriate forces Amount and rolling element taper concave bottom point contact.

The left ring or right ring or left ring, the outer rim of right ring are further fixed on annulus, and connector is passed 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, makes right ring Or left ring can move on connector, spring makes the cone point on right ring or left ring always with appropriate dynamics and rolling element point Contact.

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 utility model has abandoned Traditional Thinking, and the rolling of rolling element is precisely controlled using two conical points of retainer, and Gap is kept with rolling element, bearing inner race, outer ring, the point contact of retainer is realized in structure, utilizes spring promotion activity Epiconus makes retainer keep appropriate strength point contact with rolling element always, so as to more be precisely controlled the rolling of rolling element, from knot Low-frictional force, low vibrations, low yield heat, low noise, low bearing wear, long life are realized on structure.

The advantageous effect of the utility model compared with prior art is：

1. the utility model has abandoned Traditional Thinking, retainer with the face of rolling element is contacted and has made point contact into, so as to The friction between retainer and rolling element has been cut, has reduced bearing noise, has reduced bearing vibrations.

2. using spring promotion activity cone point retainer is made always appropriate strength to be kept to contact with rolling element, 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 utility model, right ring have dust cap function concurrently, bearing can not separately make dust cap.

4. the utility model structure further simplifies, production process is reduced, cost reduction.

5. the utility model can high-speed cruising, service life is long, suitable for various machineries.
