Abstract
The utility model discloses an oversized high-speed thrust cylindrical roller bearing retainer which is formed by the combination of two halves and can guide the inner diameter of a ferrule. The end surface of the retainer is provided with three oil holes and two annular oil grooves. The utility model can improve the lubrication between the retainer and the roller, between the retainer and a roller track as well as between the retainer and the inner diameter of the ferrule and reduce frictional heating on each sliding friction surface of the retainer, and can be applicable to high-speed working conditions.
Description
Technical field
The utility model belongs to the roller bearing technical field, relates generally to a kind of super-huge high speed cylindrical roller thrust bearing retainer.
Background technique
At present, domestic super-huge (external diameter is more than 400mm) cylindrical roller thrust bearing retainer common structure is: shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3.Because the cylindrical roller thrust bearing rotating speed is not high usually, so this retainer can be suitable for, but machine industry is more and more higher to the requirement of bearing accuracy and rotating speed in evolution, this retainer can produce a large amount of frictional heatings under the operating mode that runs up, can not form lubrication system, and can not reduce temperature rise in time, will cause the inefficacy of bearing, therefore, this retainer is very poor to high-revolving adaptability, can not meet the demands.
Summary of the invention
The purpose of this utility model is to propose a kind of oversize thrust cylinder roller bearing retainer, is used to improve between retainer and roller, retainer and the raceway, the lubrication circumstances of retainer and lasso internal diameter, improves the rotating speed of bearing.
The utility model is finished the technological scheme that its invention task taked: described cylindrical roller thrust bearing retainer is combined by two halves, is the guiding of lasso internal diameter, and the end face of described retainer is provided with three road binders holes and two annular oil grooves.
Described three road binders holes evenly are provided with, are interrupted arrangement at the circumferencial direction of retainer.
First via oilhole is from oblique retainer and the roller end face of leading to of retainer end face in the described three road binders holes; The second road binders hole leads to the lasso raceway face from the retainer end face; The Third Road oilhole leads to the lasso aperture surface from the retainer end face.
Described two annulars are made of inboard oil groove and outside oil groove, and wherein inboard oil groove is arranged on the retainer end face by the bearing bore diameter place, and outside oil groove is arranged on the position, pocket hole of retainer end face.
To sum up structure as can be known the utility model can improve between retainer and roller, retainer and the raceway, the lubrication circumstances of retainer and lasso internal diameter, reduced the frictional heating of each sliding friction surface of retainer, applicable to high-speed working condition.

Among the figure: 1, first via oilhole, 2, the second road binders hole, 3, the Third Road oilhole, 4, inboard oil groove, 5, outside oil groove, 6, the pocket hole.
Embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
Shown in Fig. 4,5,6,7,8, described cylindrical roller thrust bearing retainer, pocket hole 6 is an arcuate structure, dimidiation connects by screw, adopts the guiding of lasso internal diameter.On retainer, be provided with first, second and third road binders hole and inboard oil groove 4,5 two annular oil grooves of outside oil groove.
First via oilhole 1 can reduce the frictional heating of bottom surface, retainer pocket hole and roller end face from oblique retainer and the roller end face of leading to of retainer end face; The second road binders hole 2 leads to the lasso raceway face from the retainer end face, can reduce the frictional heating of retainer lower end surface and lasso roller surface; Third Road oilhole 3 leads to the lasso aperture surface from the retainer end face, can reduce the frictional heating of retainer guide surface and lasso internal diameter guide surface.Be set to be convenient to the second the road and Third Road oil circuit lubricated on the end face of retainer, the oil groove 4 of interior annular is arranged on the retainer end face by the bearing bore diameter place, can store the lubricant oil that enters bearing and be convenient to lubricate.For improving the lubricated of roller diameter and retainer pocket hole place, outside oil groove 5 is arranged on the position, pocket hole of retainer end face, enters the reduction heating of retainer pocket hole thereby be convenient to lubricant oil.
During work, lubricant oil enters into oil circuit by inboard oil groove 4 easily, thereby retainer end face and guide surface, roller end face are lubricated.Enter into the pocket hole by outside oil groove 5, rolling surface is lubricated.
