Abstract
This invention relates to structure improvement for a thrust bearing of a cylindrical roller, which comprises a roller bracket and a roller, wherein rolling parts are evenly distributed on the inner wall of the roller bracket; and the rolling parts are embedded on the inner wall of the roller bracket. The structure improvement disclosed by this invention uses an above-mentioned technical scheme, namely, the rolling parts are evenly distributed on the inner wall of the roller bracket; the rolling parts are embedded on the inner wall of the roller bracket; according to the structure improvement disclosed by this invention, sliding friction is changed into rolling friction on a condition of a basically-unchanged original bearing structure; a friction coefficient is reduced by more than 12 times, thus, service life of a bearing is prolonged.
Description
Technical field
The invention belongs to bearing manufacturing technology field, particularly relate to a kind of architecture advances of cylindrical roller thrust-bearing.
Background technique
At present domestic and international professional bearing manufacturer production cylindrical roller thrust-bearing is in laterally using; Because gravity causes the bearing roller bracket to contact the generation sliding friction with between centers and causes the support wearing and tearing; Roller moves down, and causes bearing to be scrapped, and axle produces and also produces wearing and tearing simultaneously.Especially when using grease lubrication, can be mingled with particle more easily owing in the lubricating grease, thereby cause wear phenomenon even more serious.Often make in heavy machine tool main shaft and barrel of tail stock main shaft use life-span short at 3-6 month.
Summary of the invention
The present invention provides the architecture advances of the cylindrical roller thrust-bearing in a kind of simple in structure, easy to use, elongated component working life for solving the technical problem that exists in the known technology.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of architecture advances of cylindrical roller thrust-bearing comprises roller bracket and roller, it is characterized in that: said roller bracket inner wall even distribution is provided with rolling member, and said rolling member is inlaid in the roller bracket inwall.
The present invention can also adopt following technical measures:
Said rolling member adopts ball; Said roller bracket inwall is provided with slideway; Increase ball retainer in the said roller bracket, be laid with through hole on the said ball retainer, the diameter of said through hole is less than the diameter of ball; Said ball is inlaid in the through hole, and said roller bracket is fixedly connected with ball retainer.
Said rolling member adopts spin, and said roller bracket inner wall even distribution is provided with spherical pore, and said ball is inlaid in the spherical pore, and said ball is inlaid in the spherical pore through the mode of pressing.
Said rolling member adopts roller construction, and said roller bracket inwall in axial direction is provided with the hole, and said hole is inboard to become to chip shape, and said roller is installed in the hole.
It is blind hole that said roller bracket inwall in axial direction is provided with the hole.
Said roller is inserted in the blind hole, and the outer end of roller is provided with catch.
Said roller is inserted in the blind hole, and the outer end of roller is provided with and presses a little, and roller is limited in the blind hole.
The bottom of said blind hole is provided with the profit oilhole.
It is through hole that said roller bracket inwall in axial direction is provided with the hole, and said roller is inserted in the through hole, is fixed with spacing catch on the two ends roller bracket of through hole.
Said at least one spacing catch is provided with the profit oilhole.
Advantage and good effect that the present invention has are: to the use condition of cylindrical roller thrust-bearing, the friction between axle and the bearing roller bracket is unavoidably in order to reduce friction.The present invention adopts technique scheme; Promptly be provided with rolling member at said roller bracket inner wall even distribution; Said rolling member is inlaid in the roller bracket inwall; The present invention becomes rolling friction by sliding friction and reduces friction factor more than 12 times under the constant basically situation of former bearing structure, thus the working life of improving bearing, and the present invention is mainly used in new product and makes and the bearing reparation.
