Abstract
The utility model relates to sporting equipment which is provided with a connecting shaft. A swarf concrete nave with an I-shaped radial cross section is arranged in the intermediate section of the excircle of the connecting shaft. A metal frame ring is sheathed on the excircle of the nave. Amphi-covers of which the lateral face is fitted with the lateral face of the nave, and the inner surface of an extending portion is fitted with the outer ring of the metal frame ring are respectively arranged on both sides of the nave on the excircle of the connecting shaft. Thereby, the utility model has the advantages of metallic material saving, easy production, high productive efficiency and uniform mass.
Description
The utility model relates to a kind of sports equipment.
At present, the flywheel of common sports equipment, be integral with metal casting whole, still, in order to reach the stability that pivots, enough weight must be arranged, and the consume metal material is big, also occurs " collapsing sand ", " destroying by rush of water " in the casting and flywheel is scrapped, long, trouble of founding time of metal casting, to make efficient low, in addition, also to carry out turning processing, cost too high (as shown in Figure 1).After this, someone produces sectional flywheel (as shown in Figure 2) in " material filling " mode, be divided into two combinations in addition with flywheel A, and make its joint and form hollow state (promptly give stay irritate mix space), give on the flywheel surface and to stay a through hole B, so that pour into an amount of substitute (as cement), to reach required weight, though can save metal material, but owing in the pouring of liquid cement, have air to enter, the contraction in the liquid cement process of setting, can influence the Mass Distribution inequality, flywheel can occur pivoting unstable.
In view of this, the purpose of this utility model is the sectional flywheel that a kind of novel sports equipment will be provided, and can ensure the quality of products is evenly distributed, and the metal material of saving is arranged again, make simple, cost and reduce.
The purpose of this utility model is achieved in that it has the axle of connecing, radial section is set on the cylindrical stage casing is I-shaped smear metal concrete wheel hub connecing, at the cylindrical of this wheel hub cover unification metal frame circle, cover on the both sides that its extension inner face cooperates with metal frame circle outer ring connecing that these wheel hub both sides on the cylindrical are provided with respectively that its side cooperates with this wheel hub side.
Owing to adopt such scheme, not only save metal material, easy to manufacture, production efficiency is high, and quality is even, result of use is good.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the solid and the profile of the metal integral flywheel of prior art.
Fig. 2 is the solid and the profile of the material filling formula flywheel of prior art.
Fig. 3 is the three-dimensional exploded view of the utility model embodiment.
Fig. 4 is combination solid and the profile of the utility model embodiment.
Among the figure: 10. flywheel, 20. smear metal concrete wheel hubs, 22. through holes, 30. metal frame circles, 32. grooves, 40. limits cover, 42. through holes, 44. extensions, 50. connect axle.
Present embodiment has and connects axle 50, smear metal concrete wheel hub 20, frame circle 30, limit cover 40.Shown in Fig. 3,4, wherein this smear metal concrete wheel hub 20 is to be formed by a certain proportion of metal fillings (or powder) and concrete blending casting, and gives at central part and to stay a through hole 22; The internal diameter of metal frame circle 30 closely is linked on smear metal concrete wheel hub 20 cylindricals, and turning goes out the guy rope usefulness of the groove 32 of appropriate depth for sports equipment transmission rope (not shown) in the middle of the outer peripheral edges of metal frame circle 30; Both sides cover 40 is with the sheet metal drawing, its side cooperates with smear metal concrete wheel hub 20 sides, and central part all gives and leaves through hole 42, so as to the through hole 22 with smear metal concrete wheel hub 20 be welded on connect the axle 50 cylindricals on, and the top extension 44 of both sides cover 40 is pressed together on groove 32 both sides on the metal frame circle 30, thus fixing metal frame circle 30.
Mixed proportion as for smear metal concrete wheel hub 20 inclusions is decided by the size of required weight fully, and for example: if in light weight, then metal ratio minimizing, concrete ratio increase, otherwise then metal ratio increases, and the concrete ratio reduces.Manufacturing speed is fast, so enhance productivity; And not being prone to material filling formula flywheel, the Mass Distribution uneven phenomenon can keep the stability that pivots.
In addition, both sides cover 40, smear metal concrete wheel hub 20 and the also available screw of metal frame circle 30 connected modes connect, and the both sides cover also can be made of plastic.
The utility model is locomotorial sectional flywheel, not only saves metal material than one-piece flywheel, and process time is short, the production efficiency height, and the Mass Distribution than " material filling " mode flywheel is even again, and flywheel pivots steadily, and result of use is good.
