Abstract
Name of the present utility model is called nylon cages cylindrical roller thrust bearing.Belong to technical field of rolling bearings.It mainly solves existing riveted retainer exists rivet and easily ruptures, punching type retainer and the high problem of nylon formula retainer manufacture cost.Its major character is: comprise the half nylon retainer that two can form overall nylon cages, and each half retainer is square outer toroid, interior annulus by cross section and the lintel group be connected between outer toroid and interior annulus forms; The inner side surface of the inner side surface of outer toroid and the outer side surface of interior annulus and two adjacent lintels forms the fenestra installing roller; In outer toroid, interior annulus side end face, interval is evenly provided with the projection and through hole that can fasten.It is powerful that the utility model nylon cages cylindrical roller thrust bearing has structure, and can resist axial impact, reliability is high, improve lubrication state, reduce operating temperature rise, alleviate bearing weight, improve the feature of bearing life, be mainly used in nylon cages cylindrical roller thrust bearing.
Description
Technical field
The utility model belongs to technical field of rolling bearings.Be specifically related to a kind of nylon cages cylindrical roller thrust bearing.
Background technique
Retainer is one of vitals of plane rolling bearing, and its effect is that guide rolls runs well in bearing working, and roller at any time all can be kept not to be scattered from bearing.Current plane cylinder roller bearing retainer has substance type and the large class of punched two.Three kinds of forms such as riveted, assembling type, entirety are mainly contained in substance type.Punching type retainer needs accurate complicated mould, and manufacture cost is high, is only applicable to the retainer that batch is large and size is less.General entity riveted retainer constitutes a latent danger to equipment because rivet in work easily ruptures, assembling type retainer has the anxiety of decoherencing equally in assembling liaison office, these two kinds of retainers are lower in precision, and nylon formula retainer comprises half nylon retainer of two molding and forming or die cast, need high frequency welding in use, need expensive equipment and mold, form overall nylon cages.
Summary of the invention
For above defect, the purpose of this utility model is to provide a kind of snap-together type nylon cages cylindrical roller thrust bearing, the hidden danger that when riveted retainer can be avoided to assemble, retainer liaison office easily decoherences, is significantly increased simultaneously in bulk strength, rigidity and geometric accuracy, lubrication effect.
Technical solution of the present utility model is: a kind of nylon cages cylindrical roller thrust bearing, comprise the half nylon retainer that two can form overall nylon cages, each half nylon retainer is square outer toroid, interior annulus by cross section and the lintel group be connected between outer toroid and interior annulus forms, and it is characterized in that: the inner side surface of the inner side surface of described outer toroid and the outer side surface of interior annulus and two adjacent lintels forms the fenestra installing roller; In the outer toroid of two and half nylon retainers, interior annulus side end face, interval is evenly provided with the projection and through hole that can fasten.
The inner side surface of the lintel described in technical solution of the present utility model is provided with axial cylindrical connected in star.
Convex or the concave point hangnail of projection band described in technical solution of the present utility model; Recessed or the salient point hangnail of described through hole band; Convex or the concave point hangnail of projection matches with the recessed of through hole or salient point hangnail.
The beneficial effects of the utility model are:
1, the shape of fenestra is suitable for injection molding, also can be used for brill, milling and broaching and completes; 2, the internal-and external diameter of outer toroid, interior annulus is not by technologic restriction, and programmable wider, be applicable to axial lead, mechanical strength is abundant, also can lengthen roller and improve bearing performance; 3, this kind of nylon holding frame structure is powerful, and can resist axial impact, reliability is high; 4, arc fenestra has the effect locked by roller, prevents the roller when back-up ring sheds to be scattered out; 5, retainer arc fenestra both ends of the surface can be improved the lubrication state of retainer guide surface, reduce operating temperature rise, weight reduction, improve bearing life.
The utility model is mainly used in nylon cages cylindrical roller thrust bearing.

Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described.
The utility model nylon retainer cylindrical roller thrust bearing as shown in Figures 1 to 5.Half nylon retainer is made up of outer toroid 1, interior annulus 2 and the lintel 3 groups be connected between outer toroid 1 and interior annulus 2, and lintel 3 groups comprises some equally distributed lintels 3, and the cross section of outer toroid 1, interior annulus 2 is square.The inner side surface 3-1 of the inner side surface 1-1 of the outer toroid 1 and outer side surface 2-1 of interior annulus 2 and two adjacent lintels 3 forms the circular arc fenestra installing roller, and the inner side surface 3-1 of lintel 3 is provided with axial cylindrical connected in star 4.The side end face of outer toroid 1, interior annulus 2 and lintel 3 crossover location is evenly alternately offered some projections 5 of fastening and through hole 6, projection 5 is with convex or concave point hangnail, through hole 6 is with recessed or salient point hangnail, and the convex or concave point hangnail of projection 5 matches with the recessed of through hole 6 or salient point hangnail.
The inner side surface 3-1 of the adjacent lintel 3 of half nylon retainer two put into by cylindrical roller 7, fastened by second half nylon retainer and is assembled into a set of nylon cages cylindrical roller thrust bearing.
