The utility model provides an among the prior art lead to the bearing can't bear a large amount of loading capacity's problem because of roller quantity is too few.
Description
Technical Field
The utility model relates to a bearing holder technical field specifically is a novel roller holder.
Background
The bearing is an important part in the modern mechanical equipment and is widely used. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and ensure its rotation precision. With the development of the technology, the use occasions of the bearing are wider and wider, and the requirements are more and more specialized; for example, in some large-sized linkage mechanisms, the bearings must bear a large amount of bearing capacity, but the roller bearings in the prior art cannot bear a large amount of load capacity under the condition of ensuring that the number of rollers is fixed, and under the action of high load capacity, the rollers in the prior art can jump out of the retainer to cause bearing scattering, while the bearings equipped with a large number of rollers have an excessive number of rollers to cause the bearings to be too heavy, and the retainer is too large to cause the bearings to be too heavy, which further affects the rotation of the linkage mechanism, and the bearings have a low rotation speed due to the excessive weight, which finally causes the efficiency of the linkage mechanism to be reduced.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a novel roller holder leads to the problem that the bearing can't bear a large amount of loading capacity because of roller quantity is too little among the solution prior art.
In order to achieve the purpose, the utility model provides a novel roller holder, comprising a frame body, set up the pocket hole that a plurality of is used for a plurality of rollers of holding respectively on the support body, a plurality of the pocket hole is the hoop along the support body periphery wall and arranges, and is adjacent all be provided with the roof beam body, every between the pocket hole all be provided with on the roof beam body and be used for preventing that the roller from breaking away from the locating part in pocket hole, every all be provided with the restriction piece that is used for preventing a plurality of rollers of pocket downthehole scurrying on the pocket hole.
The technical scheme is adopted, and the method has the advantages that: compared with the prior cylindrical roller bearing and needle bearing structure, the technology realizes that two or more rollers can be arranged in one pocket, so that the bearing capacity of the bearing is enhanced and the wide strength of the roller beam is ensured under the condition that the inner space of the bearing is not increased, compared with the full roller bearing in the prior art, the bearing cage has the advantages that the problem of bearing cage scattering when no inner ring exists is solved, a plurality of rollers arranged in each pocket can be distributed on each roller body when the bearing bears the load force, the problem that the bearing capacity of a single roller is too high due to too small number of rollers is avoided, the bearing is further ensured not to fail due to high load force damage, and a plurality of rollers are installed in each pocket, so that the weight of the cage can be reduced in some cases where the number of rollers needs to be fixed, the retainer not only lightens the self-weight, but also ensures that the roller can not be separated from the roller path of the inner ring and the outer ring of the bearing.
The utility model discloses further set up: the locating part is the boss, every the boss all is provided with the arcwall face that is used for with roller surface contact towards the one side of adjacent pocket hole.
The technical scheme is adopted, and the method has the advantages that: all be provided with the boss on every roof beam body, every boss all is provided with the arcwall face towards the one side of adjacent pocket hole, and the arcwall face can contact with adjacent roller surface, ensures that the roller can not break away from the pocket hole under the condition that bears a large amount of loading power, and further the normal rotation of guaranteeing the roller, and the arcwall face can also effectively coat roller surface grease, avoids the roller surface to lead to roller surface certain department friction loss to increase because grease distributes the inequality.
The utility model discloses further set up: the limiting piece comprises a limiting rod, one end of the limiting rod is connected with the inner wall of one side of the pocket, the other end of the limiting rod is connected with the inner wall of the other side of the pocket, and the orientation of the limiting rod is perpendicular to the rolling direction of the roller.
The technical scheme is adopted, and the method has the advantages that: the setting of restriction pole can effectually prevent that two or a plurality of rollers in the pocket from extrudeing the position of scurrying mutually, avoids appearing the phenomenon that the roller breaks away from the pocket.
The utility model discloses further set up: the wide footpath of support body left side wall is less than the wide footpath of support body right side wall, support body left side aperture is less than support body right side aperture.
The technical scheme is adopted, and the method has the advantages that: the wide footpath of support body left side wall is less than the wide footpath of support body right side wall, and support body left side aperture is less than support body right side aperture for support body both sides ring size is inconsistent, makes things convenient for operating personnel to install the roller or carry out drawing of patterns and handles.
