Abstract
The utility model discloses a bearing roller for rolling mills, wherein the rolling surface of the roller is a rotating surface structure which is formed through rotating a flat straight circular arc around a central line, the tilting state of the flat straight circular arc enables both sides of the roller to form a big end surface with big section area and a small end surface with small section area, and the edge portions of both sides of the end surface of the roller are rounding-off. A round groove with flat bottom is arranged on the central portion of the big end surface, the groove wall of the groove is in an inward concave circular arc surface transition form, and the small end surface forms a spherical surface groove from the edge to the center. The bearing roller of the utility model is limited in the axial direction, which only needs arranging top resisting parts in the concave portions of the end surfaces of both sides, thereby not only reducing the end surface of the roller and the abrasion area of a traditional retainer ring, but also reducing the abrasion and prolonging the service life of a bearing. Simultaneously the rolling surface is set into the circular arc shape rotating structure, which increases the thickness of the roller and the wear-resisting performance.
Description
Technical field
Present technique relates to a kind of bearing roller.
Background technique
Under the prior art, cylindrical roller to be relied on and rib is set realizes roller spacing along the bearing axial direction.Problem is, because the area of contact of rib and cylindrical roller end face is bigger, the bearing under running up is along with the carrying out of rotating, and area is big because wear and tear aggravation, and then influences the working life of bearing.
In addition, the face that rolls of cylindrical roller and contacting of inside and outside circle raceway along with wearing and tearing produce the faying surface shortage gradually, thereby cause vibrations, the instability of bearing in turning course.
Summary of the invention
The present invention aims to provide durable, wear-resisting bearing roller, and the working life of therefore improving bearing.
The invention provides a kind of milling train bearing roller, the face that rolls of roller is the turning surface structure that straight circular arc constitutes around the center line revolution; The straight circular arc heeling condition makes the roller both sides form big large end face and the little small end face of sectional area of sectional area; The edge of roller both sides end face is rounded down.The center of large end face goes out to be provided with the groove of circular flat bottom, and the cell wall of described groove is the arc surface interim form of indent; Small end face from the edge to be formed centrally spherical groove.
Its bearing shaft of bearing roller provided by the invention to spacing, only need by the parts of fending off are set in the depression of both sides end face, and will fend off parts and inner ring or the outer ring is fixing gets final product, thereby dwindled the wear area of roller end face and traditional back-up ring, and then reduce wear, improve the working life of bearing.The face that rolls simultaneously is arranged to circular-arc revolving structure, has strengthened roller thickness and wear-resisting property, has further strengthened the usability of bearing.
Description of drawings
Fig. 1 is the structural representation of bearing roller of the present invention.
Embodiment
With reference to figure 1 bearing roller provided by the invention, the face that rolls of roller is the turning surface structure that straight circular arc constitutes around the center line revolution; The straight circular arc heeling condition makes the roller both sides form big large end face and the little small end face of sectional area of sectional area.Bearing of the present invention is mainly used on the milling train.Among the figure, the edge of roller both sides end face is rounded down.The state of right shade part partial cutaway as shown in Figure 1 in addition, the center of large end face goes out to be provided with the groove of circular flat bottom, and the cell wall of groove is the arc surface interim form of indent.And left side dash area partial cutaway structure demonstrates among the figure: small end face from the edge to be formed centrally spherical groove.
