Abstract
The invention discloses a kind of point contact type bearing spill rolling element, including：Body portion and tapering, tapering are cone, and tapering is fixed in the both sides in body portion, and the cone in tapering is inside, and formation taper is recessed, and the taper concave bottom portion 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 spill 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 present invention is in order to overcome with the shortcomings that upper bearing (metal) and deficiency, there is provided a kind of frictional force is small, heat production is few, noise is low, shake
Dynamic small point contact type bearing spill rolling element.
In order to achieve the above object, the present invention adopts the technical scheme that：A kind of point contact type bearing spill rolling element, bag
Include：Body portion and tapering, tapering are cone, and tapering is fixed in the both sides in body portion, and the cone in tapering is inside, and formation taper is recessed,
The taper concave bottom portion in two taperings 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 that the cone in the tapering is recessed is 20 degree -170 degree.
The present invention has abandoned Traditional Thinking, when using the taper of rolling element two it is recessed with support a retainer, make retainer with
There is gap body portion, bearing inner race, the outer ring of rolling element, while the rolling of rolling element is refined control, second, according to shaft strength
Size changes rolling element body portion and bearing internal external circle contact area, or can be point contact.Bearing roller connects for the point of retainer
Touch, also contacted with bearing inner race, outer ring for point or minimum area contacts.Low-frictional force is realized from structure, heat production is few, noise
Low, 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.
