Examples

The cooperation is shown in fig. 1-2, the utility model discloses a magnetic control flywheel, its mainly use is on spinning, exercise bicycle, rowing machine, realizes the regulation of resistance through cooperating with the magnetic control structure.

The utility model provides a magnetic control flywheel, includes flywheel body 10, flywheel outer lane 20, axle sleeve 30 and a plurality of connector 40, flywheel body 10 is the annular, axle sleeve 30 is located the middle part of flywheel body 10, connector 40 one end is connected with axle sleeve 30, and the other end is connected with flywheel body 10, just axle sleeve 30, connector 40 and flywheel body 10 integrated into one piece connect, certainly, axle sleeve 30, connector 40 and flywheel body 10 also can be the shaping respectively or connector 40 and other arbitrary one shaping together, and the shaping mode is not unique, design according to actual demand can, and three integrated into one piece can effectively improve production efficiency, and the quality is also better simultaneously. The section of the flywheel outer ring 20 is U-shaped, and correspondingly covers the circumferential side surface and two end surfaces of the flywheel body 10.

The shaft sleeve 30 is used for mounting a flywheel, and different mounting scenes have different structures corresponding to the shaft sleeve 30, and the flywheel can be designed according to actual requirements. In this embodiment, the middle of the shaft sleeve 30 has a through hole, the inner walls of the two ends of the shaft sleeve 30 are both provided with inner steps 31 for mounting a bearing, and the outer wall of one end of the shaft sleeve is provided with a belt groove 32 for connecting a belt. This is one structural design of the bushing 30, but is not limited thereto.

The shaft sleeve 30, the connecting body 40 and the flywheel body 10 are integrally formed by cast iron. The connecting body 40 exists, the hollow part exists in the middle of the flywheel, compared with the design of the existing flywheel disc body (the whole flywheel is a solid disc body), the consumption of cast iron is greatly reduced, but the inertia of the flywheel is not greatly influenced integrally (the inertia of the flywheel is mainly influenced by the weight of the edge of the flywheel), and the inertia of the flywheel with the thickness of the split flywheel is increased obviously. Therefore, by adopting the design of the structure of the connecting body 40, the using amount of cast iron can be effectively reduced and the cost is reduced under the same inertia requirement.

The flywheel outer ring 20 is an aluminum layer or a copper layer, and the periphery side face and two end faces of the flywheel body 10 are simultaneously coated, the three-surface coating design effectively improves the firmness of connection between the flywheel outer ring 20 and the flywheel body 10, and the flywheel outer ring can not bulge or loosen even if the flywheel outer ring is expanded with heat and contracted with cold when in use, so that the stability of magnetic resistance is ensured.

Specifically, the flywheel outer ring 20 includes a main body portion 21 and two folding portions 22 located at two ends of the main body portion 21, the main body portion 21 and the folding portions 22 respectively and correspondingly cover the circumferential side surface and two end surfaces of the flywheel body 10, a plurality of rivets 23 are connected between the folding portions 22 and the flywheel body 10, and the plurality of rivets 23 are uniformly arranged along the circumferential direction of the flywheel body 10. Rivet 23 is squeezed into flywheel body 10 from the book of flywheel one side portion 22 in, the design of flywheel, the fastness of being connected between flywheel outer lane 20 and the flywheel body 10 has further been promoted, and because of rivet 23 is located the terminal surface of flywheel, its week side (being the week side of flywheel outer lane 20) is not destroyed, still complete continuous curved surface, the experiment proves, this structure flywheel does not exist basically because of the pause sense and the noise that rivet 23 of current week side arouse when using, effectively improved the use and experienced.

During assembly, the flywheel body 10 and the flywheel outer ring 20 are respectively molded firstly, the flywheel outer ring 20 is an annular ring at the moment, the width of the annular ring is larger than the thickness of the flywheel body 10, then the flywheel outer ring 20 is assembled to the periphery of the flywheel split body through a shrink fit process, two ends of the annular ring are folded and pressed to two end faces of the flywheel body 10 and fixed with the flywheel outer ring, the annular ring forms the flywheel outer ring 20 with the application section being in a U shape, and finally a plurality of rivets 23 are driven into the position of the folding and pressing part 22 of the flywheel outer ring 20 along the circumferential direction of the flywheel, so that the connection between the flywheel outer ring 20 and the flywheel body 10 is further strengthened.

In this embodiment, the width of the folding portion 22 is 10-20mm. The width of the folded portion 22, that is, the size of the folded portion 22 along the radial direction of the flywheel body 10, the folded portion 22 needs to have a certain width, and the connection with the flywheel body 10 is firmer, but it does not need to be too wide, which increases the cost. The width of the folding part 22 is equal to the width of the end face of the flywheel body 10. Thus, the appearance of the flywheel can be improved, and the increase of inertia can be realized by properly increasing the thickness of the flywheel body 10.

In this embodiment, the connecting body 40 is a strip-shaped plate, and the thickness thereof is smaller than that of the flywheel body 10. The connecting body 40 mainly plays a role of connecting and supporting, the thickness of the connecting body can be properly reduced, the supporting effect (meeting the requirement) and the inertia (having little influence) of the flywheel can not be influenced, meanwhile, the use of raw materials can be reduced, and the cost is reduced.

In this embodiment, the number of the connecting bodies 40 is three, and the connecting bodies are uniformly arranged along the circumferential direction of the flywheel body 10. The number of the connecting bodies 40 is appropriate, so that the connection support performance is ensured, excessive waste of raw materials is not needed, and the number of three is preferred.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
