Description

A kind of bearing funnel retainer

Technical field

The utility model is related 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 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, The small bearing funnel retainer of low noise, vibrations.

In order to achieve the above object, the technical scheme adopted by the utility model is that：A kind of bearing funnel retainer, including a left side Ring, right ring, connector, cone point, Zuo Huan, right ring design are the identical circular ring shape of shape, are uniformly set respectively on Zuo Huan, right ring In respect of the identical cone point of shape, the tip of the cone point on Zuo Huan, right ring is opposite, the line of opposite cone point with Bearing rotation direction is vertical, and connector advantageously reduces for cylindrical or segment, the streamlined design that direct-axis holds rotation direction Wind is made an uproar, and connector one end is fixedly connected on the midpoint between left two cone point of ring, and the other end, which is fixedly connected on right ring two, to be justified On midpoint between conical points, the tip of cone point and taper rolling element taper concave bottom point contact.

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 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, so as to more be precisely controlled rolling The rolling of kinetoplast realizes low-frictional force, low vibrations, low yield heat, low noise, low bearing wear, long life from 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. the left ring of the utility model, right ring have dust cap function concurrently, bearing can not separately make dust cap.

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

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

Specific embodiment

Embodiment one, as shown in Figure 1, Figure 2, a kind of bearing funnel retainer, including left ring 1, right ring 2, connector 3, cone Point 4, left ring 1, right ring 2 are designed as the identical circular ring shape of shape, even respectively on left ring 1, right ring 2 to be designed with the identical circle of shape Conical points 4, the cone point 4 on left ring 1, right ring 2, tip is opposite, and the tip line of opposite cone point 4 is rotated with bearing Direction is vertical, and the size of cone point 4, quantity, the size of taper and spill rolling element, quantity, taper are adapted, and cone is less than It bores recessed；Connector 3 is cylindrical or segment, and the streamlined design that direct-axis holds rotation direction advantageously reduces wind and makes an uproar, connector 3 One end is fixedly connected on the midpoint between 1 liang of cone point 4 of left ring, the other end be fixedly connected on right 2 liang of cone points 4 of ring it Between midpoint on, connector 3 is not contacted with the inner ring of bearing 6, outer ring 7 and spill rolling element 5, the inner ring of connector 3 and bearing 6th, there are gap, two cone concave bottoms and the sharp 4 tip points of cone on retainer of spill rolling element 5 between outer ring 7 and spill rolling element 5 Contact.

The cone point 4 is 6.

Sharp 4 tapers of cone are 100 degree.

Embodiment two, as shown in Figure 1, Figure 2, a kind of bearing funnel retainer, including left ring 1, right ring 2, connector 3, cone Point 4, left ring 1, right ring 2 are designed as the identical circular ring shape of shape, even respectively on left ring 1, right ring 2 to be designed with the identical circle of shape Conical points 4, the cone point 4 on left ring 1, right ring 2, tip is opposite, and the tip line of opposite cone point 4 is rotated with bearing Direction is vertical, and the size of cone point 4, quantity, the size of taper and spill rolling element, quantity, taper are adapted, and cone is less than It bores recessed；Connector 3 is cylindrical or segment, and the streamlined design that direct-axis holds rotation direction advantageously reduces wind and makes an uproar, connector 3 One end is fixedly connected on the midpoint between 1 liang of cone point 4 of left ring, the other end be fixedly connected on right 2 liang of cone points 4 of ring it Between midpoint on, connector 3 is not contacted with the inner ring of bearing 6, outer ring 7 and spill rolling element 5, the inner ring of connector 3 and bearing 6th, there are gap, two cone concave bottoms and the sharp 4 tip points of cone on retainer of spill rolling element 5 between outer ring 7 and spill rolling element 5 Contact.
