Abstract
The utility model discloses a nylon retainer of a thrust cylinder roller bearing, which belongs to the technical field of roller bearings and mainly solves the problem that rivets of the existing riveting type retainers are easy to crack, and stamping retainers and nylon retainers are high in manufacture cost. The nylon retainer is characterized by comprising two half nylon retaining devices capable of forming the whole nylon retainer, each half retaining device is composed of an outer ring, an inner ring and a lintel group connected between the outer ring and the inner ring, and the cross sections of the inner ring and the outer ring are both square. The inner lateral face of the outer ring, the outer lateral face of the inner ring and the inner lateral faces of two adjacent lintels form a window hole for installing a roller. Protruding columns and through holes which can be buckled together are evenly arranged on the lateral end faces of the outer ring and the inner ring at intervals. The nylon bearing has the advantages of being strong in structure, capable of withstanding axial impact and high in reliability, improving lubricating conditions, reducing working temperature rise and prolonging service life of the bearing, and is mainly used in the thrust cylinder roller bearing.
Description
Technical field
The utility model belongs to technical field of rolling bearings.Be specifically related to a kind of nylon cages of 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, at any time all can keep roller from bearing, not to be scattered.Present plane cylinder roller bearing retainer has substance type and punching press type two big classes.Mainly contain three kinds of forms such as riveted formula, assembling type, integral body in the substance type.The punching type retainer needs the mould of sophisticated, and manufacture cost is high, only is applicable to big in batches and the less retainer of size.General entity riveted formula retainer ruptures easily owing to rivet in the work and equipment is constituted a latent danger; The assembling type retainer has the anxiety of decoherencing equally in assembling liaison office; These two kinds of retainers are lower aspect precision, and nylon formula retainer comprises half nylon retainer of two molding and forming or die cast, needs high frequency welding in use; Need expensive equipment and mold, form whole nylon cages.
Summary of the invention
To above defective; The purpose of the utility model provides a kind of snap-together type cylindrical roller thrust bearing nylon cages; Make its hidden danger that can avoid riveted formula retainer when assembling retainer liaison office to be prone to decoherence, be significantly increased aspect lubricated in bulk strength, rigidity and geometric accuracy simultaneously.
The technical solution of the utility model is: a kind of cylindrical roller thrust bearing nylon cages; Comprise two the half nylon retainers that can form whole nylon cages; Each half retainer be square outer toroid, interior annulus by the cross section and be connected outer toroid and interior annulus between the lintel group form, it is characterized in that: the inner side surface of described outer toroid and in the inner side surface of outer side surface and two adjacent lintels of annulus constitute the fenestra of installation roller; Evenly be provided with the projection and the through hole that can fasten on outer toroid, the interior annulus side end face at interval.
The inner side surface of the lintel described in the technical solution of the utility model is provided with the axial cylindrical connected in star.
Protruding or the concave point hangnail of projection band described in the technical solution of the utility model; Recessed or the salient point hangnail of through hole band; Protruding or the concave point hangnail of projection matches with the recessed of through hole or salient point hangnail.
The beneficial effect of the described cylindrical roller thrust bearing nylon cages of the utility model is:
The shape of fenestra is suitable for injection moulding processing, also can be used for brill, milling and broaching and accomplishes; The interior external diameter of outer toroid, interior annulus does not receive technologic restriction, programmable broad, and applicable to axial lead, mechanical strength is abundant, and the roller that also can extend improves bearing performance; This kind nylon cages structure is powerful, can resist axial impact, and reliability is high; The arc fenestra has the effect with the roller locking, prevents that roller is scattered out when back-up ring sheds; Can improve the lubrication state of retainer guide surface on the retainer arc fenestra both ends of the surface, reduce the work temperature rise, improve bearing life.
The utility model is mainly used in the nylon cages of cylindrical roller thrust bearing.

Fig. 3 is C-C sectional structure schematic representation of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is done further description:
The described half nylon retainer of the utility model such as Fig. 1, Fig. 2, shown in Figure 3.Half nylon retainer by outer toroid 1, interior annulus 2 and be connected outer toroid and interior annulus between lintel form for 3 groups, lintel comprises some equally distributed lintels for 3 groups, the cross section of outer toroid 1, interior annulus 2 is square.The outer side surface 2-1 of the inner side surface 1-1 of outer toroid 1 and interior annulus 2 and the inner side surface 3-1 of two adjacent lintels 3 constitute the circular arc fenestra that roller is installed, and the inner side surface 3-1 of lintel 3 is provided with axial cylindrical connected in star 4.Evenly alternately offer some projections that fasten 5 and through hole 6 on the side end face of outer toroid 1, interior annulus 2 and lintel 3 crossover locations; Projection 5 is with protruding or the concave point hangnail; Through hole 6 is with recessed or the salient point hangnail, and the protruding or concave point hangnail of projection 5 matches with the recessed of through hole 6 or salient point hangnail.Two and half nylon retainers can fasten the nylon cages that forms a whole.
Claims (3)
