Abstract
The invention relates to an integrated retainer, and in particular relates to a dual-crown externally embedded trapezoidal lock type high-speed bearing integrated retainer which belongs to the technical field of a bearing. The high-speed bearing integrated retainer comprises a retainer body and a plurality of pockets which penetrates through the thickness direction of the retainer body, wherein a pocket beam is arranged among the pockets; two trapezoidal section type crown structures are arranged on the outer diameter beam of the pocket beam, consequently an embedded roller body can be locked conveniently, and the droop amount of the roller body also can be controlled; the pockets outside the rotating center are straight pockets and are arc pockets in the rotating center; on the one hand, the roller body can be mounted conveniently, on the other hand, the arc surfaces of the pockets can guide the roller body well, so as to facilitate the high-speed rotation of the bearing; four corners of each pocket are provided with process tanks; a pocket structure with a straight surface and an arc surface can be processed conveniently with a forming knife, and consequently, the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of integrated retainer, specifically relate to the outer trapezoidal locking-type high-speed bearing of the embedding integrated retainer of a kind of double comb, 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, develop a kind of minimizing and reduce because part too much causes retainer precision, guarantee that rolling element does not drop out from retainer external diameter embeds simultaneously, and have less sag of chain retainer be imperative.
Summary of the invention
In view of the defect that prior art exists, the object of the invention 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 technical solution adopted in the present invention is the outer trapezoidal locking-type high-speed bearing of the embedding integrated retainer of double comb, it comprises: support body and through the pocket hole of 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 processes by high-temperature tempering; Retainer surface adopts silver-plated processing.
The invention has the advantages that:
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, by high-temperature tempering, improved the strength of materials, 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.
