Abstract
The present invention relates to retainer, especially the retainer on medical high-precision bearing, specifically a kind of revolving support nylon cages, comprise banded retainer, retainer is provided with steel ball location hole, described retainer is welded by four arcs shape nylon band, and retainer is the end to end comb shaped structure of segmented; The head and the tail joint of retainer leaves the gap of 3-15mm.Retainer design have employed the end to end comb shaped structure of segmented, material adopts commercial nylon, can fundamentally solve the noise produced because of the mutual collision of retainer like this, the own wt of bearing can also be alleviated simultaneously, banded nylon cages also reduces friction torque and noise while meeting high speed performance, the present invention can not only enhance product performance, manufacturing efficiency, saving labour force, and the quality control in production process easily realizes, reject rate reduces greatly, improves quality of product and the performance of enterprises.
Description
Technical field
The present invention relates to retainer, the retainer especially on medical high-precision bearing, specifically a kind of revolving support nylon cages and preparation process thereof.
Background technique
Due in medical apparatus, as large medical apparatus such as gamma knife, CT machine, nuclear magnetic resonance machines, the bearing used needs highi degree of accuracy, low noise, long-life, high reliability, therefore it is also proposed sizable requirement to the important component part retainer of bearing.In the development field of large slewing bearing retainer, the selecting of material generally gets the carbon constructional quality steel cold rolled sheet or steel band that GB/T699-1999, GB/T13237, GB/T709-1988 specify, meet the performance requirement of bearing products, but this type of material has, and weight is large, rub serious shortcoming, can not meet the high-precision requirement of medical equipment.
Summary of the invention
Object of the present invention, is exactly for solving prior art Problems existing, and devises a kind of revolving support nylon cages and preparation process thereof.
Revolving support nylon cages in the present invention, comprises banded retainer, and retainer is provided with steel ball location hole, and described retainer is welded by four arcs shape nylon band, and retainer is the end to end comb shaped structure of segmented; The head and the tail joint of retainer leaves the gap of 3-15mm.
Described comb shaped structure refers to the two ends at retainer, semi-circle structure rounded after the docking of termination.
Described retainer adopts whole welding type to weld open type two kinds of modes with segmentation and welds, and soldering point adopts scrap (bridge) welding.
Described nylon cages adopts PA6 or the PA66 polyamide nylon of the structure of molecule mainly linear structure of chain to make.
A preparation process for revolving support nylon cages, step is: carry out fine finishing nylon band after the inspection of raw and process materials, removes burr afterwards and carries out plane straightening and side straightening again; Heat shaping after adjustment, make nylon band camber, then two ends boring full-round hole, then remove the half of circular hole, form comb structure; The soldering opening of each section of nylon band of fine finishing afterwards, and scrabble up circle; Use ultra-sonic welded interface; Weld rear heating shaping, examination cover; Then final inspection, cleaning, painting protective film.
Beneficial effect of the present invention draws by such scheme: because retainer design have employed the end to end comb shaped structure of segmented, material adopts commercial nylon, can fundamentally solve the noise produced because of the mutual collision of retainer like this, the own wt of bearing can also be alleviated simultaneously, banded nylon cages also reduces friction torque and noise while meeting high speed performance, can enter and produces in batches and be applied to the various environment needing safety verification.Adopt nylon A66, PA6 to have excellent corrosion resistance, high temperature resistant, high insulation, low coefficient of friction etc., its feature embodies a concentrated expression of that intensity is high, impact capacity good, wear-resisting, endurance, oil resistant.Within the scope of the bearing capacity of bearing roller, inner-outer sleeve, the requirement that bearing rotating speed is increased to more than 30000r/min can be met, realize the vibration values of bearing at 12 μm/s(ZV3), noise decibel value is at 15.132dB(V3) below.Production technology application of advanced equipment and automatic jig, not only improve product performance, manufacturing efficiency, saved labour force, and the quality control in production process easily realizes, reject rate reduces greatly, improves quality of product and the performance of enterprises.
As can be seen here, the present invention compared with prior art has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.
accompanying drawing illustrates:
Fig. 1 is cross section structure schematic diagram of the present invention;
Fig. 2 is plan view of the present invention;
Fig. 3 is the structural representation at welding scrap (bridge) place;
Fig. 4 is manufacturing process flow process figure of the present invention;
Fig. 5 is the floor map of retainer.
Wherein, 1 is steel ball, and 2 is retainer, and 3 is bearing inner sleeve, and 4 is soldering point, and 5 is first paragraph nylon band, and 6 is second segment nylon band, and 7 is the 3rd section of nylon band, and 8 is the 4th section of nylon band.
embodiment:
In order to understand the present invention better, explain embodiments of the present invention in detail below in conjunction with accompanying drawing.
Embodiment: as shown in Figure 1, 2, revolving support nylon cages in the present invention, comprises banded retainer 2, and retainer 2 is provided with steel ball 1 location hole, described retainer 2 is welded by four arcs shape nylon band, and retainer 2 is the end to end comb shaped structure of segmented; The head and the tail joint of retainer 2 leaves the gap of 3-15mm.Retainer 2 adopts whole welding type to weld open type two kinds of modes with segmentation and welds.Soldering point 4 adopts scrap (bridge) to weld as shown in Figure 3.Described nylon cages adopts PA6 or the PA66 polyamide nylon of the structure of molecule mainly linear structure of chain to make.
As shown in Figure 4, a kind of preparation process of revolving support nylon cages, step is: carry out fine finishing nylon band after the inspection of raw and process materials, removes burr afterwards and carries out plane straightening and side straightening again; Heat shaping after adjustment, make nylon band camber comb structure, then bore hole; The soldering opening of each section of nylon band of fine finishing afterwards, and scrabble up circle; Use ultra-sonic welded interface; Weld rear heating shaping, examination cover; Then final inspection, cleaning, painting protective film.
Above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited in above-mentioned citing, and the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
