Abstract
The invention provides a light cylindrical roller bearing, which comprises an internal ring, an external ring, a rolling element and a retainer, wherein the cylindrical rolling element is of a hollow connection structure, and the external layer of the rolling element is connected with the internal core of the rolling element by a jagged tilting support frame; the external layer and the internal core of the rolling element are made of bearing alloy; and the tilting support frame is made of solid carbon fiber tube stock and can be firmly bonded with the external layer and the internal core of the rolling element by hot melting or other welding modes. The invention has the remarkable effects that the rolling element of the cylindrical roller bearing is improved, and the original solid structure of the bearing is substituted by the jagged support structure, therefore, the used expensive bearing alloy is reduced, and the whole structure becomes lighter and more convenient; meanwhile, the service life of the bearing is not affected, and the improvement achieves more advantages.
Description
Technical field
The present invention relates to a kind of bearing, especially a kind of light cylindrical roller bearing.
Background technique
Bearing is the fixed member in the machinery.When other parts produce relative movement each other on axle, be used for retainer shaft the central position and control the parts of this motion, just be referred to as bearing.
Study carefully it and be used for saying be to support, promptly literal interpretation is used for holding axle, but this is the part of its effect, supports its essence and can bear radial load exactly.Also can be understood as it and be used for fixing axle.Be exactly that stationary axle makes it can only realize rotating, and control its moving axially and radially.It is exactly can not work that motor does not have the consequence of bearing at all.Because axle may be to the motion of any direction, and require axle to rotate during machine operation.Can not realize the effect of transmission theoretically, moreover, bearing also can influence transmission, must realize good lubricating in order to reduce this influence on the bearing of high speed shaft, the bearing that has itself has had lubricated, is called prelubricated bearing, and most bearing must have lubricant oil, be responsible for when running up, because friction not only can increase energy consumption, more fearful is to be easy to damage bearing.The saying that sliding friction is changed into rolling friction is unilateral, because kind of a thing that is sliding bearing is arranged.Under certain loading, revolution that bearing is experienced before spot corrosion occurring or hour number are called bearing life.Since accuracy of manufacturing, the difference of material uniformity coefficient, even same material, the same a collection of bearing of same size uses under same operating conditions, its life-span length is also inequality.For determining the standard of bearing life, bearing life and reliability are connected.
But, if prolong the life-span of bearing, just must increase materials, certainly will increase the weight of bearing, increased frictional force.
Summary of the invention
At the problems referred to above, the invention provides a kind of light cylindrical roller bearing.
A kind of light cylindrical roller bearing, comprise inner ring, outer ring, rolling element, retainer, it is characterized in that its cylindrical rolling element is the hollow linkage structure, connect by jagged inclination supporting frame between the skin of rolling element and the inner core, its outer and inner core employing bearing metal, the inclination supporting frame adopts solid carbon fiber tubing, can be by the skin and the inner core strong bonded of hot melt or other welding manners and rolling element.
Remarkable result of the present invention is that the rolling element to the roller bearing bearing improves, adopt a kind of flexuose supporting structure, substituted the solid construction of original bearing thus, a large amount of uses of expensive bearing metal have not only been saved, also make total become lighter, do not influence the working life of bearing simultaneously, achieve many things at one stroke.
Description of drawings
Accompanying drawing is the rolling element schematic representation of light cylindrical roller bearing
Wherein: 1, skin; 2, the hollow linkage structure; 3, inner core; 4, the inclination supporting frame.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing: the cylindrical rolling element of bearing is a hollow linkage structure 2, connect by jagged inclination supporting frame 4 between the skin 1 of rolling element and the inner core 3, its skin 1 and inner core 3 adopt bearing metal, inclination supporting frame 4 adopts solid carbon fiber tubing, can be by the skin 1 and inner core 3 strong bonded of hot melt or other welding manners and rolling element, the outer ring of bearing and inner ring are when relative rotation, the light-duty bearing of hollow can rotate freely faster, inclination supporting frame 4 adopts carbon fiber to make, can support certain pressure, bearing roller lubricant oil evenly can be scatter simultaneously.
Apply the present invention in the mechanical system, rolling element to the roller bearing bearing improves, adopt a kind of flexuose supporting structure, substituted the solid construction of original bearing thus, not only save a large amount of uses of expensive bearing metal, also made total become lighter, do not influenced the working life of bearing simultaneously, achieve many things at one stroke, can also save 25% materials cost.
