Description

A kind of bearing spill retainer with thrust

Technical field

The utility model is related 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 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 spill 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 spill with thrust is kept Frame, recessed including left ring, right ring, connector, cone, activity cone is recessed, and 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 recessed, and uniform design has the identical activity circle of shape on left ring or right ring Taper is recessed, and cone is recessed opposite with movable cone is recessed recess portion, 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 right ring two is lived On midpoint between dynamic cone is recessed.

The activity cone is recessed to include cylinder groove, the conical recessed, spring of activity, and cylinder groove is cylindrical or square column type Or elliptical cylinder-shape design, the identical cylinder groove of shape, the recessed system of activity cone 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 movable conical concave bottom Portion, spring make movable cone is recessed can be moved up and down in cylinder groove, and the recess portion that spring makes movable cone recessed is always 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 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, and spring makes Right ring or left ring can move on connector.The concave bottom portion that spring makes the cone on right ring or left ring recessed is always with appropriate forces Degree and rolling element tapering 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, using the recessed rolling for being precisely controlled rolling element of two tapers 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 Cone is recessed to make retainer keep appropriate strength point contact with rolling element always, so as to more be precisely controlled the rolling of rolling element, from Low-frictional force, low vibrations, low yield heat, low noise, low bearing wear, long life are realized in 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 is recessed 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.
