Abstract
The utility model discloses an improved thrust cylinder roller bearing mainly comprising a seat retainer, a cylindrical roller, a check ring, a retainer stand, a retainer cover, an elastic cylindrical pin and a shaft ring, wherein the cylindrical roller is arranged between the seat retainer and the shaft ring; the retainer cover and the retainer stand are connected through the elastic cylindrical pin; the outside of the seat retainer is provided with the check ring; and one end surface of the retainer is designed to have a special structure. The improved thrust cylinder roller bearing can reduce the bearing failure risk and prolong the service life of the bearing.
Description
Technical field the utility model relates to technical field of bearings, concrete relates to a kind of a kind of improved cylindrical roller thrust bearing that is applicable in the machineries such as heavy machine tool, high-power marine gearbox, oil-well rig, highwall-drilling machine.
Its bearing washer raceway of background technique cylindrical roller thrust bearing is the plane, rolling element is a cylindrical roller, rolling element and raceway are slip and add rolling condition during running, thereby limit speed is lower, can only bear unidirectional thrust load and slight the impact, the unidirectional axial displacement of energy restrictive axes (or shell) therefore can be made unidirectional axially locating, do not allow axle and shell aperture axis that inclination is arranged, to processing, be equipped with high requirement.This class bearing is mainly used in the machineries such as heavy machine tool, high-power marine gearbox, oil-well rig, highwall-drilling machine.In traditional cylindrical roller thrust bearing structure, retainer pocket hole and roller are easy to wearing and tearing, cause bearing using process middle (center) bearing temperature to raise, and bearing is in operation process, the fast rotational of retainer etc. all can cause the damage of retainer, blowout patche and seat ring raceway face etc.
The defective that summary of the invention exists in view of prior art, the purpose of this utility model are will provide a kind of can reduce the damage of bearings risk and can improve a kind of improved cylindrical roller thrust bearing in its life-span.
For achieving the above object, the technical solution that the utility model adopted is: a kind of improved cylindrical roller thrust bearing, mainly form by seat ring, cylindrical roller, back-up ring, maintenance stand, retainer lid, elastic cylindrical pin and blowout patche.Described cylindrical roller is arranged between seat ring and the blowout patche, and the retainer lid is connected by elastic cylindrical pin with keeping stand, and the seat ring outside is provided with back-up ring.
An end face of described retainer is designed to special tectonic.
The utility model has the advantages that: 1, the bearing race structure improves to some extent, and makes another end face of retainer be able to corresponding location at axial direction, alleviates retainer pocket hole and roller fretting wear, and the temperature rise that helps bearing using process middle (center) bearing is alleviated; 2, designed the special construction retainer, the destructive momentum that self has produced when having reduced the retainer fast rotational effectively reduces the spoilage of retainer; 3, retainer end face is designed to special tectonic, has effectively improved the bearing lubrication operating mode, directly improves bearing working life.
