Abstract
The invention discloses a kind of point contact type bearing funnel rolling element, including：Body portion and tapering, tapering are cone, and the bottom in tapering is fixed on the both sides of body surface, and the cone in tapering is outside, and the cone in two taperings and the center in body portion are point-blank.The present invention has abandoned Traditional Thinking, and retainer is contacted with the face of rolling element and has made into a little to contact, and so as to cut the friction between retainer and rolling element, reduces bearing noise, reduces bearing vibrations.
Description
Technical field
The present invention relates to bearing arrangement, more particularly to a kind of structure of point contact type bearing funnel rolling element.
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.
At present, the rolling element of bearing is mostly spheroid or cylinder, big with retainer contact area, causes frictional force big, easily
Heat production, noise is big, and vibrations are big, influence bearing high-speed cruising and service life.
The content of the invention
The shortcomings that present invention is in order to overcome above bearing roller and deficiency, there is provided a kind of frictional force is small, heat production is few, noise
Point contact type bearing funnel rolling element low, vibrations are small.
In order to achieve the above object：The present invention adopts the technical scheme that：A kind of point contact type bearing funnel rolling element, bag
Include：Body portion and tapering, tapering are cone, and the bottom in tapering is fixed on the both sides of body surface, and the cone in tapering is outside, two cones
The cone in portion and the center in body portion are point-blank.
The body portion is spherical or cylindrical or the dumbbell bodily form or circle rhombohedreon shape or double sphericals or double round rhombohedreon shapes.
The taper of the tapering cone is 30 degree -160 degree.
The present invention has abandoned Traditional Thinking, when using the cone of rolling element two with support a retainer, make retainer with rolling
There is gap body portion, bearing inner race, the outer ring of kinetoplast, while the scrolling position of rolling element is refined control, second, according to bearing by
Power size changes rolling element body portion and bearing inner race, outer ring contact area, or can be point contact.Bearing roller is retainer
Point contact, rolling element is also bearing inner race, the contact of the point of outer ring or minimum area contact.Low-frictional force is realized from structure,
Heat production is few, and noise is low, and vibrations are small, the target of service life length.
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.
2nd, the present invention makes bearing arrangement further simplify, and production process is reduced.Cost reduces.
3, the present invention can high-speed cruising.Service life is grown, suitable for various machineries.

Specific embodiment
Embodiment one：As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, a kind of point contact type bearing funnel rolling
Kinetoplast, including：Body portion 1 and tapering 2, tapering 2 are cone, and tapering 2 is separately fixed at the both sides on the surface of body portion 1, can also body
Portion 1 and tapering 2 are integrated, and the cone in tapering 2 is outside, and the cone in two taperings 2 and the center in body portion 1 are point-blank.
The body portion 1 is spherical or cylindrical or the dumbbell bodily form or circle rhombohedreon shape or double sphericals or double round rhombohedreons
Shape.
The taper of the cone of tapering 2 is 60 degree.
The body portion 1 and bearing inner race 6, outer ring 7, a contact may be designed as according to stress size or face contacts.
The body portion 1 between bearing inner race 6, outer ring 7, the cone tip part in tapering 2 respectively with the left ring 3 on retainer, right
The concave bottom point contact of taper recessed 5 on ring 4.
Embodiment two：As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, a kind of point contact type bearing funnel rolling
Kinetoplast, including：Body portion 1 and tapering 2, tapering 2 are cone, and tapering 2 is separately fixed at the both sides on the surface of body portion 1, can also body
Portion 1 and tapering 2 are integrated, and the cone in tapering 2 is outside, and the cone in two taperings 2 and the center in body portion 1 are point-blank.
The body portion 1 is spherical or cylindrical or the dumbbell bodily form or circle rhombohedreon shape or double sphericals or double round rhombohedreons
Shape.
The taper of the cone of tapering 2 is 90 degree.
The body portion 1 and bearing inner race 6, outer ring 7, a contact may be designed as according to stress size or face contacts.
The body portion 1 between bearing inner race 6, outer ring 7, the cone tip part in tapering 2 respectively with the left ring 3 on retainer, right
The concave bottom point contact of taper recessed 5 on ring 4.
