Description

Flywheel structure

This creation belongs to the technical field of a flywheel, specifically a flywheel structure that can improve the inertia effect, so that when the flywheel speed is increased, not only can the yaw of high-speed rotation be reduced, but the inertia weight curve can be significantly elongated, further It can reduce the weight of the flywheel and reduce the preparation cost of the flywheel.

According to medical research, in recent years, due to medical research, a small number of multiple movements, the effectiveness of preventing heart disease is as good as the intensive exercise for a long time, so the market The development of fitness equipment with a variety of different training functions for users to exercise indoors, and such sports equipment is mainly exercise bikes, elliptical machines, weight trainers, ski machines, treadmills, etc.; In order to provide the user with the load during the movement to improve the movement effect and smooth movement, usually a flywheel with a specific weight (also commonly known as a counterweight wheel, a flywheel, a weight wheel or a damper wheel) is provided. As shown in the figure, taking the existing elliptical machine as an example, the elliptical machine is provided with a flywheel (50) on the frame (10), and a crank for driving the flywheel (50) at the other end of the frame (10). The group (15) allows the user to actuate the flywheel (50) by stepping on the crank set (15) and generate a load by centrifugal force when the flywheel (50) is rotated at a high speed.

The flywheel (50) is mainly used for inertial motion when the side crank is turned At the lower limit position, the left and right leg afterburning process is completed. The crank can be continuously rotated by the inertial force of the flywheel (50), and when it passes the lower limit position, it enters the next loop. Therefore, when driving the flywheel (50), it is more necessary to use the weight of the flywheel (50) to lengthen the curve of its inertia weight to balance the resistance, so the flywheel (50) needs to have a specific weight and load to generate effective inertia. The weight curve, while the existing flywheel evolved from an early cast iron wheel to a plastic wheel, a fan wheel and a magnetron wheel; since the solid cast iron wheel is manufactured with a larger diameter solid casting, the larger the diameter, the cost The higher, and because it is more in need of secondary processing, the use of larger manufacturing equipment is required, and the intangible cost is increased. The plastic wheel and the fan wheel have the problem of insufficient weight. As for the magnetic wheel, there are problems such as uneven weight and inertia. Therefore, the general flywheel is subject to considerable restrictions and cannot fully meet the inertial action of the sports equipment, so that the application The movement effect of the flywheel's sports equipment is relatively limited; in other words, because the existing flywheel is difficult to combine the inertia, reduce the yaw and the low cost, so that it can not effectively meet the sports demand, how to solve the above The problem is the industry's urgent need for developers.

In view of this, the creator has in-depth discussion on the problems faced by the aforementioned existing flywheels, and actively pursues solutions through years of research and development experience in related industries. Through continuous efforts in research and trials, he has finally succeeded in developing a kind of solution. The structure of the flywheel can overcome the troubles and inconvenience caused by the lack of inertia and balance.

Therefore, the main purpose of this creation is to provide a flywheel structure, which can increase the inertia effect, effectively and significantly lengthen the inertia weight curve, The sporting effect of high sports equipment.

In addition, the second primary objective of the present invention is to provide a flywheel structure that can improve the balance of operation to reduce the yaw of high-speed rotation, thereby reducing the probability of damage to the sports equipment due to vibration, and achieving smoothness during exercise. And comfort.

A further major objective is to provide a flywheel structure that simplifies the overall structure to achieve a lighter, lower cost effect, while significantly reducing its manufacturing costs to increase economic efficiency.

Based on this, the present invention mainly achieves the foregoing objectives and effects through the following technical means; the present invention comprises: a base plate having an axle portion, and the base plate is provided with an outwardly extending wheel frame at an outer edge of the axle portion. And the wheel frame is formed with at least two equal-angled, equidistant weight mounting portions; and two weighting blocks, wherein the inner diameter contour of each of the weight mounting portions corresponds to a cross section of the weighting block, so that each weighting block The lengths of the end faces of the weights are less than or equal to the length of the weights, so that the long axis of the weights is parallel to the axis of the base axle, and the weights are The column is mounted on the base plate.

In summary, through the above-mentioned technical means, the base plate of the present flywheel structure is provided with equiangular and equidistant multiple weights, and each of the weights is installed in a column shape, so when the flywheel rotates at a high speed, It can generate high centrifugal force, and its inertia weight curve is obviously elongated. At the same time, because it uses a small size weight, it can effectively control the counterweight of the flywheel, so that the flywheel can be balanced, and the yaw can be reduced at high speed. The phenomenon of the sports equipment used in the creation of the flywheel can be improved, so the creation of the flywheel is in terms of "low intrinsic lightness, increased inertia force and reduced yaw". The existing flywheel is more effective.

In order to enable the reviewing committee to further understand the composition, features and other purposes of the present invention, the following is a preferred embodiment of the present invention, and the detailed description of the present invention is as follows, and the person skilled in the art can implement it.
