Abstract
The utility model relates to an integrated cage, in particular relates to a double-crown externally-embedded trapezoidal locking type high-speed bearing integrated cage and belongs to the field of bearings. The cage comprises a cage body and pockets penetrating the thickness direction of the cage body. Pocket beams are arranged between the pockets and two trapezoidal section crown type structures are respectively arranged on outer diameter beams of the pocket beams, so that an embedded rolling body is conveniently locked and the droop quantity of the rolling body is controlled at the same time; the cage pockets adopt straight pockets outside the gyration center and arc pockets in the gyration center, so that on the one hand, the rolling body is conveniently installed, on the other hand, the rolling body can be well guided by means of the cambered surfaces of the pockets and the high-speed operation of the bearing is benefitted; process tanks are formed in four corners of the pockets and the structures of the straight and arc pockets are conveniently processed by utilizing a forming cutter, so that the production efficiency is increased.
Description
Technical field
The utility model relates to a kind of integrated retainer, specifically relates to the outer trapezoidal locking-type high-speed bearing of the embedding integrated retainer of a kind of double comb, and it belongs to field of bearings.
Background technique
Along with industrial development, bearing is as the indispensable parts of machinery, and people are also increasing day by day to the requirement of its speed and intensity.Retainer is as the indispensable constituent element of bearing, to its requirement want with increase.For meeting bearing at a high speed and high strength, a kind of minimizing because part too much causes retainer precision of development reduces, and ensures that rolling element does not drop out from retainer external diameter embeds simultaneously, and have less sag of chain retainer be imperative.
Model utility content
In view of the defect that prior art exists, the purpose of this utility model is to provide a kind of double comb the outer trapezoidal locking-type high-speed bearing of embedding integrated retainer.
For achieving the above object, the technological scheme that the utility model adopts is the outer trapezoidal locking-type high-speed bearing of the embedding integrated retainer of a kind of double comb, it comprises: support body and the pocket hole through the thickness direction of described support body, it between pocket hole, is pocket hole beam, it is characterized in that: described pocket hole beam external diameter is provided with two projections, He Zhidou hole, You Hudou hole, pocket hole combines and forms, and gyration center adopts straight pocket hole outward, in gyration center, adopt arc pocket hole, four jiaos, pocket hole is respectively equipped with technology groove.
Described projection is trapezoid cross section formula crown structure.
Described retainer adopts GCr15 material, and by high-temperature tempering processing; Retainer surface adopts silver-plated processing.
The utility model has the advantage of:
1, pocket hole Liang Waijingliang is provided with two trapezoid cross section formula crown structures, is not only convenient to the rolling element of sealed embedding, controls the sag of chain of rolling element simultaneously;
2, retainer pocket hole adopts straight pocket hole outside gyration center, adopts arc pocket hole in gyration center, is convenient on the one hand rolling element and installs, and pocket hole cambered surface can play good guiding function to rolling element on the other hand, is beneficial to bearing and runs up;
3, four jiaos, pocket hole is provided with technology groove, utilizes forming cutter to be convenient to face directly the processing that adds cambered surface pocket hole structure, has improved manufacturing efficiency;
4, retainer adopts GCr15 material, improved the strength of materials by high-temperature tempering, surface adopts silver-plated processing simultaneously, reduces retainer surface friction coefficient, the silver wearing away in operation process also can play lubrication simultaneously, guarantees the reliability that bearing runs up.
