Description

健身康复器材惯性飞轮变速系统 技术领域  Fitness rehabilitation equipment inertia flywheel shifting system
本实用新型涉及齿轮变速装置， 特别是一种健身康复器材惯性飞轮变速 系统。  The utility model relates to a gear shifting device, in particular to an inertial flywheel shifting system of a fitness rehabilitation equipment.
背景技术 Background technique
传统的健身车的惯性飞轮变速系统的结构请参阅图 1。如图所示：它包括 安装惯性飞轮变速系统的车架 101、 传递外界扭力力矩的曲柄 102、 大皮带轮 103、 皮带 104、 和小皮带轮连接为一体的惯性飞轮 108; 另外还有包含惰轮 105、 杠杆板 106、 弹簧 107的惰轮机构。 当健身或康复者运动时， 运动者首 先驱动曲柄 102旋转，大皮带盘轮 103因固定在曲柄 102上而以相同的角速度 绕曲柄轴旋转，这样带动皮带 104、惯性飞轮 108—起运动，因为大皮带轮 103 是小皮带轮（小皮带轮与惯性飞轮 108是一体的） 的直径几倍， 惯性飞轮 108 的旋转角速度同样是曲柄 102的几倍，惯性飞轮 108的转速越高，锻炼或康复 的效果就越佳。 由于大小皮带轮的直径差异， 皮带传递扭力的效率就会欠佳， 为了有高的传动效率， 变速系统中就有惰轮结构， 来增加小皮带轮的包覆角， 减少皮带打滑， 从而使健身运动者较好的达到健身或康复的目的。  See Figure 1 for the structure of the inertial flywheel shifting system of a conventional exercise bike. As shown in the figure: it comprises a frame 101 on which an inertia flywheel shifting system is mounted, a crank 102 that transmits an external torque moment, a large pulley 103, a belt 104, and an inertia flywheel 108 in which the small pulleys are integrated; and an idler 105 is also included. The idler mechanism of the lever plate 106 and the spring 107. When the fitness or rehabilitation person moves, the athlete first drives the crank 102 to rotate, and the large belt pulley 103 rotates around the crank shaft at the same angular velocity by being fixed on the crank 102, so that the belt 104 and the inertia flywheel 108 are driven to move because The large pulley 103 is several times the diameter of the small pulley (the small pulley is integrated with the inertia flywheel 108), and the rotational angular velocity of the inertia flywheel 108 is also several times that of the crank 102. The higher the rotational speed of the inertia flywheel 108, the effect of exercise or rehabilitation The better. Due to the difference in diameter between the large and small pulleys, the efficiency of the belt transmitting torque will be poor. In order to have high transmission efficiency, the shifting system has an idler structure to increase the coverage angle of the small pulley and reduce the belt slippage, thereby making the exercise. It is better to achieve the purpose of fitness or rehabilitation.
然而， 对于由使用大小皮带轮、 皮带、 多轮机构健身康复器材而言， 对 生产制造和使用有很多不便和麻烦。此惯性飞轮变速系统有如下弊端：一是制 造时车架多是焊接而成，而大小皮带轮的形位公差需保证，这样在焊接和装配 时要保证制造精度就需增加工艺装备， 并反复校对， 从而增加劳动强度， 影响 生产效率。二是大小皮带轮外加惰轮机构， 再加上车架等， 设计时在符合安全 规定的情况下， 经常会很难布置它们彼此的位置， 占用的空间位置比较大； 三 是皮带轮、皮带结构的变速结构， 出厂时皮带调整过紧容易断裂， 减少使用寿 命； 皮带调整过松会打滑； 大小皮带轮位置没调整对齐会产生跑带、甚至皮带 脱落； 再加上运动者个体差异， 使售后服务工作量变大； 特别是当变速比较大 时， 对惰轮机构的要求会增加， 惰轮机构的结构也会变得更复杂。 However, for fitness rehabilitation equipment that uses size pulleys, belts, and multi-wheel mechanisms, there are many inconveniences and troubles in manufacturing and use. This inertial flywheel shifting system has the following disadvantages: First, the frame is mostly welded during manufacture, and the shape tolerance of the large and small pulleys needs to be ensured, so that the manufacturing precision must be increased during the welding and assembly, and the proofreading is repeated. , thereby increasing labor intensity, impact Productivity. Second, the size of the pulley plus the idler mechanism, plus the frame, etc., in the design of the safety regulations, it is often difficult to arrange their position, occupying a large space; Third, the pulley, belt structure The shifting structure is easy to break when the belt is adjusted too tightly at the factory, which reduces the service life; the belt is too loose to slip; the size of the pulley is not adjusted and the alignment will cause the belt to run, or even the belt will fall off; plus the individual differences of the athletes, the after-sales service The amount becomes larger; especially when the shifting speed is large, the requirements on the idler mechanism are increased, and the structure of the idler mechanism becomes more complicated.
