有许多机械产品,如各种精密机床、汽车、包装机械、食品加工机械等机械结构,都需要有联轴节。目前大多数传动装置都是采用刚性、半刚性、柔性联轴节和万向节。随着科学技术的不断发展,机械传动结构也要求越来越高。对于要求结构紧凑、传动精度高、无振动无角速度变化,而且输入输出轴之间偏心传动,变化频繁的场合,使用万向节联轴节是不能满足这 There are many mechanical products, such as all kinds of precision machine tools, automobiles, packaging machinery, food processing machinery and other mechanical structures, all need couplings. At present, most of the transmissions are made of rigid, semi-rigid, flexible couplings and universal joints. With the continuous development of science and technology, mechanical transmission structure also requires higher and higher. For the requirements of compact structure, high precision transmission, no vibration and angular velocity changes, and the input and output shaft eccentric transmission, frequent changes in the occasion, the use of universal joints can not meet this
