Abstract
The invention discloses a large-size integral intersected tapered roller bearing and relates to the field of bearings. An inner ring and an outer ring are ferrules in integral structures; the stiffness and strength of the ferrules are improved; the defect that the accuracy of the bearing is changed due to the change of relative positions of ferrules in double-half-ring structures is overcome; a retainer is arranged in a conoid roller path; conoid rollers are intersected equidistantly and arranged in the retainer perpendicularly; the problem of low linear velocity at the two ends of roller length is solved very well; the rollers rotate synchronously; the slide is avoided; the pure rolling can be achieved; a friction coefficient is decreased greatly; the friction among the rollers and running noises are reduced.
Description
[technical field]
The present invention relates to field of bearings, especially relate to a kind of large-scale integral crossed-circle taper roller bearing.
[background technique]
Known, existing crossed roller bearing, rolling element is cylindrical roller, roller length two ends swing diameter of living in is different in the bearing operation process, linear velocity is different, roller end line speed is large in the outer part, and it is little by inboard roller end line speed, thereby can cause that roller is crooked to skid, surface friction drag is increased, because structural limitations makes the turnability of bearing and precision will not reach requirement, other needs in order to assemble, inner ring of its middle (center) bearing or outer ring are two half coil structures, cause the rigidity of lasso and intensity relatively poor, assembling and when using two half coil structures can cause the bearing accuracy change because dislocation causes the relative position change.
[summary of the invention]
In order to overcome the deficiency in the background technique, the invention discloses a kind of large-scale integral crossed-circle taper roller bearing, the present invention utilizes outer ring, inner ring, retainer, tapered roller, roller is packed into by the outer ring filling hole in the raceway, filler plug is connected and fixed by circular cone locating stud and inner ring, outer ring and inner ring adopt the overall structure lasso, thereby have improved rigidity and the intensity of lasso, have overcome two half coil structures lassos and have changed the shortcoming that causes bearing accuracy to change owing to relative position.
In order to realize described goal of the invention, the present invention adopts following technological scheme:
A kind of large-scale integral crossed-circle taper roller bearing, comprise outer ring, inner ring, retainer, rolling element, described inner ring and outer ring are overall structure, inner ring is in the inside of outer ring, be respectively equipped with raceway at the outer facade of described inner ring and the interior facade of outer ring, bearing is divided into internal tooth and outer toothing, radially be provided with filling hole without gear ring, rolling element is packed into by filling hole in the raceway, between rolling element, be provided with retainer, after filling is finished, filler plug is put into filling hole, without the positioning pin hole on the gear ring filler plug is fixed by described with the circular cone locating stud again.
Described large-scale integral crossed-circle taper roller bearing, described rolling element is tapered roller, is crossed as right-angle array in raceway.
Described large-scale integral crossed-circle taper roller bearing, described retainer is separate type, adopts brass material to make.
Described large-scale integral crossed-circle taper roller bearing, the diameter of described large-scale integral crossed-circle taper roller bearing is at least 2000mm.
Owing to adopted technique scheme, the present invention to have following beneficial effect:
Described large-scale integral crossed-circle taper roller bearing, comprise outer ring, inner ring, retainer, rolling element, described inner ring and outer ring are the overall structure lasso, the overall structure lasso has improved rigidity and the intensity of lasso, has overcome two half coil structures lassos and has changed the shortcoming that causes bearing accuracy to change owing to relative position; Be provided with retainer in the cone raceway, tapered roller equidistantly is crossed as right-angle array in retainer, well remedied the problem of roller length two ends linear differentials, roller is rotated synchronously, avoid sliding phenomenon, can realize pure rolling, friction factor is reduced greatly, reduce the friction between the roller and reduce running noise.
