Abstract
The utility model discloses a suspension beam type combined holder for a second-class bearing, which belongs to a bearing fitting. The utility model has the structure that the utility model is composed of two corresponding annular retainer rings and a roller separator plate arranged between the two corresponding annular retainer rings, wherein mortise holes are uniformly arranged on the retainer rings at intervals; both ends of the roller separator plate are respectively provided with a rabbet, and the rabbets on both ends are respectively inserted into the mortise holes of the two retainer rings to make the retainer rings and the roller separator plate connected together; one end of the side surface of the roller separator plate forms a tiny arc shape, so the width of the end of the roller separator plate is slightly greater than that of the other end, which causes a roller to be in the suspended state in the process of using and assembling the bearing. Only the bottom or the top of the side surface of the roller separator plate of the utility model has tiny radian, the contact surface with the roller is reduced, and accordingly, the friction coefficient is decreased; the radiation effect is good, and a self-lubrication function is added by an oil storage tank formed in the middle; the service life of the bearing is extended, the material is saved and the manufacture cost is reduced.
Description
1, technical field
The utility model relates to a kind of Bearing fittings, specifically a kind of overarm formula secondary bearing composite cage.
2, technical background
Bearing is a kind of mechanical parts of supporting axle rotation, and bearing bracket stand is between the inner ring and outer ring of bearing, and the back-up roller kinetoplast makes it between the inside and outside circle of bearing along the equidistant even distribution of circumference the member of stress equalization.Rolling element is that columniform retainer is the secondary bearing retainer, and it is widely used in machinery such as diesel engine, motor, automobile gearbox, rolling mill.Outsourcing design in present employed secondary bearing retainer generally adopts, be that its roller bulkhead sides is an arc, whole side all contacts with roller, so its friction factor is big, radiating effect is poor, temperature rise is fast, poor lubrication, bearing often because friction-produced high temperature, make lubricating grease excessive and burn out roller, so that bearing is scrapped in movement process.The life-span of bearing is low, changes frequently, and must influence the effective utilization of whole equipment when changing bearing.
3, summary of the invention
Technical assignment of the present utility model is at above deficiency, provide a kind of simple in structure, use material few, low, the easy accessibility of cost, the overarm formula secondary bearing composite cage that friction factor is little.
The technological scheme that its technical problem that solves the utility model adopts is: evenly be arranged at intervals with mortise on the back-up ring, the two ends of roller dividing plate are respectively arranged with tenon, and the tenon at two ends inserts respectively in the mortise of two back-up rings back-up ring and roller dividing plate are linked together; Roller bulkhead sides one end is small arc, makes this width of roller dividing plate be slightly larger than the other end width, makes bearing roller in use and assembly process be in suspended state.
The bottom, side of described roller dividing plate is small arc, and the width of roller dividing plate bottom is slightly larger than top width.
The top, side of described roller dividing plate is small arc, and the width of roller dividing plate bottom is slightly larger than top width.
Described tenon exceeds the back-up ring end face.
Described tenon exceeds back-up ring end face 1.5～2mm.
A kind of overarm formula secondary bearing composite cage of the present utility model is compared with prior art, its roller bulkhead sides has only the bottom or has only the top to be provided with small radian, reduced surface of contact greatly with roller, thereby reduced friction factor, good heat dissipation effect, the middle oil storage tank that forms has increased self-lubricating function, has prolonged the working life of bearing, and has saved material.Reduced fabricating cost.

Among the figure: 1, tenon; 2, back-up ring; 3, roller dividing plate; 4, roller; 5, outer ring; 6, inner ring.
5, embodiment
Explain below with reference to Figure of description a kind of overarm formula secondary bearing composite cage of the present utility model being done.
A kind of interior overarm formula secondary bearing composite cage shown in accompanying drawing 1 to 4, it is made of two relative annular retaining rings and the roller dividing plate that is arranged on their centres, evenly be arranged at intervals with mortise on the back-up ring, the two ends of roller dividing plate are respectively arranged with tenon, and the tenon at two ends inserts respectively in the mortise of two back-up rings back-up ring and roller dividing plate are linked together; The roller bulkhead sides is small arc near the bottom of bearing inner race, makes the bottom width of roller dividing plate be slightly larger than top width.
The structural representation of the bearing of overarm formula secondary bearing composite cage in the use shown in the accompanying drawing 5, roller is arranged between the inner ring and outer ring of bearing, the roller dividing plate of interior overarm formula secondary bearing composite cage evenly separates roller, and makes roller be in suspended state.
Outer overarm formula secondary bearing composite cage as shown in Figure 6, the side of its roller dividing plate is small arc near the top of bearing outer ring, makes the width of the width on roller dividing plate top greater than the degree end.After being installed on bearing, can make the roller of bearing be in suspended state.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
