Abstract

The utility model discloses a kind of bearing spill retainers, including left ring, right ring, connector, cone is recessed, Zuo Huan, right ring is the identical circular ring shape of shape, Zuo Huan, the cone that uniform design has shape identical respectively on right ring is recessed, Zuo Huan, the recessed opening of cone on right ring is opposite, the recessed concave bottom point line of opposite cone is vertical with bearing rotation direction, connector one end be fixedly connected on two cone of left ring it is recessed between midpoint on, the other end be fixedly connected on two cone of right ring it is recessed between midpoint on, the upper conical concave bottom portion of retainer is point contact with taper rolling element conical points.The utility model, which contacts retainer with the face of rolling element, has made point contact into, so as to cut the friction between retainer and rolling element, reduces bearing noise, reduces bearing vibrations.

Description

A kind of bearing spill retainer

Technical field

The utility model is related 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 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 spill 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 spill retainer, including a left side Ring, right ring, connector, cone are recessed, and Zuo Huan, right ring are the identical circular ring shape of shape, and uniform design has respectively on Zuo Huan, right ring The identical cone of shape is recessed, and the recessed opening of the cone on Zuo Huan, right ring is opposite, the recessed concave bottom point line of opposite cone with Bearing rotation direction is vertical, connector one end be fixedly connected on two cone of left ring it is recessed between midpoint on, the other end, which is fixed, to be connected Be connected on two cone of right ring it is recessed between midpoint on, the upper conical concave bottom portion of retainer is point contact with taper rolling element conical points.

The connector is cylindrical 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 utility model has abandoned Traditional Thinking, recessed using two tapers of retainer, is precisely controlled the rolling of rolling element, and Gap is kept with rolling element, bearing inner race, outer ring, the point contact of retainer is realized in structure, is also promoted using spring Movable circular cone is recessed, and retainer is made always appropriate strength to be kept to contact with rolling element, 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. 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 and Figure 2, a kind of bearing spill retainer, including left ring 1, right ring 2, connector 3, circle Taper recessed 4, left ring 1, right ring 2 are designed as the identical circular ring shape of shape, and uniform design has the shape identical respectively on left ring 1, right ring 2 Cone recessed 4, recessed 4 opening of cone on left ring 1, right ring 2 is opposite, the concave bottom portion line and axis of opposite cone recessed 4 Hold that rotation direction is vertical, the size of cone recessed 4, quantity, the size of taper and taper rolling element, quantity, taper are adapted, and are bored It is recessed that point is less than cone；Connector 3 is cylindrical or segment, and the streamlined design that direct-axis holds rotation direction advantageously reduces wind and makes an uproar, 3 one end of connector is fixedly connected on the midpoint between left 1 liang of cone of ring recessed 4, and the other end is fixedly connected on right 2 liang of circular cones of ring On midpoint between shape recessed 4, connector 3 is not contacted with the inner ring of bearing 6, outer ring 7 and taper rolling element 5, connector 3 and bearing Inner ring 6, have gap, two cones and upper conical recessed 4 bottom of retainer of taper rolling element 5 between outer ring 7 and taper rolling element 5 Point contact.

The cone recessed 4 is 8.

The opening taper of the cone recessed 4 is 120 degree.

Embodiment two, as shown in Figure 1 and Figure 2, a kind of bearing spill retainer, including left ring 1, right ring 2, connector 3, circle Taper recessed 4, left ring 1, right ring 2 are designed as the identical circular ring shape of shape, and uniform design has the shape identical respectively on left ring 1, right ring 2 Cone recessed 4, recessed 4 opening of cone on left ring 1, right ring 2 is opposite, the concave bottom portion line and axis of opposite cone recessed 4 Hold that rotation direction is vertical, the size of cone recessed 4, quantity, the size of taper and the taper rolling element in retainer, quantity, cone Degree is adapted, and it is recessed that cone is less than cone；Connector 3 is favourable for cylindrical or segment, the streamlined design that direct-axis holds rotation direction In drop low wind noise, 3 one end of connector is fixedly connected on the midpoint between left 1 liang of cone of ring recessed 4, and the other end is fixedly connected on On midpoint between right 2 liang of cones of ring recessed 4, connector 3 is not contacted with the inner ring of bearing 6, outer ring 7 and taper rolling element 5, even Have gap between the inner ring 6 of junctor 3 and bearing, outer ring 7 and taper rolling element 5, two cones of taper rolling element 5 on retainer The recessed 4 bottom point contact of taper.
