Abstract
The utility model 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 utility model has abandoned Traditional Thinking, and retainer with the face of rolling element is contacted and has made point contact into, so as to cut the friction between retainer and rolling element, reduces bearing noise, reduces bearing vibrations.
Description
Technical field
The utility model is related 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 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.
At present, the rolling element of bearing is mostly sphere 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.
Utility model content
A kind of frictional force is small, heat production is few, noise in order to overcome the shortcomings that upper bearing (metal) and deficiency, to provide for the utility model
Point contact type bearing spill rolling element low, vibrations are small.
In order to achieve the above object, the technical scheme adopted by the utility model is that:A kind of point contact type bearing spill rolls
Body, 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, form cone
Shape is recessed, and 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 utility model has abandoned Traditional Thinking, when using two taper of rolling element it is recessed with support a retainer, make holding
There are gap in body portion, bearing inner race, the outer ring of frame and rolling element, while the rolling of rolling element is refined control, second is that according to bearing
Stress size changes rolling element body portion and bearing internal external circle contact area or can be point contact.Bearing roller is retainer
Point contact is also contacted with bearing inner race, outer ring for point contact or minimum area.Low-frictional force is realized from structure, heat production is few,
Low noise, vibrations are small, the target of service life length.
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.
2nd, the utility model makes bearing arrangement further simplify, and production process is reduced.Cost reduction.
3, the utility model can high-speed cruising.Service life is long, suitable for various machineries.
