Core of the present utility model provides a kind of tapered roller bearing retainer, and this tapered roller bearing retainer can improve the lubricating condition of bearing, improves the flexibility of running, reduces operating noise, prolongs the working life of bearing and retainer.Another core of the present utility model provides a kind of tapered roller bearing that comprises above-mentioned tapered roller bearing retainer.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 2, Fig. 2 provides the structural representation of a kind of embodiment of tapered roller bearing retainer for the utility model.
In this embodiment, the tapered roller bearing retainer comprises fenestra beam 1, forms fenestra between the adjacent fenestra beam 1, and the some rolling element (not shown)s in the bearing are in respectively in the corresponding fenestra, guide it to roll on correct raceway; In addition, fenestra beam 1 separates some rolling elements successively, produces collision and friction each other to prevent rolling element, avoids the wearing and tearing and the fluctuation of service of bearing.
Both sides at retainer fenestra beam 1 are processed with pressure slope face 2 respectively, contact with the crest line of fenestra beam 1 to avoid rolling element.At this moment, the contact position of rolling element and retainer fenestra beam 1 bi-side is a pressure slope face 2, can improve the bulk strength of retainer, thereby improve the contact performance between fenestra beam 1 and the rolling element, and then improve the flexibility and reliability of bearing operation.
On the pressure slope face of fenestra beam 1, longitudinal groove 3 is set.Described herein vertically is along the pressure slope face 2 of fenestra beam 1 and the direction that parallels with tapered roller bearing retainer axis, the i.e. length direction of the pressure slope face 2 of fenestra beam 1; With its accordingly, hereinafter mentioned laterally and above-mentioned vertically be relative notion, i.e. axially perpendicular with bearing.Because the contact length of rolling element and longitudinal groove 3 is directly determining degree of lubrication between the two, therefore, the longitudinal length of longitudinal groove 3 preferably approaches the optimum scheme of the axial length of rolling element, that is to say, increases contact length between the two to greatest extent.Like this, rolling element is in rolling process, and rolling voxel line integral body basically all contacts with longitudinal groove 3, thus make rolling element in the axial direction can with the lubricant grease comprehensive engagement that is stored in the longitudinal groove 3, integral body is lubricated, and obtains best lubrication effect.Further, just because of evenly lubricated fully between the two, the operation of bearing is more steadily reliable.Certainly, the axial length with rolling element is unsuitable yet for the longitudinal length of longitudinal groove 3, as long as can store lubricant grease, in the scope that the utility model is asked for protection yet.In fact, for each pressure slope face 2, the longitudinal groove 3 on it also can adopt segmented design: some longitudinal grooves 3 are along the lateral alternate of pressure slope face 2; Perhaps, some longitudinal grooves 3 are separated vertically from beginning to end relatively and between the two successively.Obviously, so design can satisfied on the basis of basic greasy property, improves the overall work intensity of fenestra beam 1 greatly.
