1、齿轮制造业的概貌齿轮和齿轮装置同轴承、螺栓等一样,是各种产业机械、汽车、船舶、机车、飞机等所有机械和装置不可缺少的重要零部件。齿轮和齿轮装置里有圆柱齿轮、锥齿轮、蜗轮、螺旋齿轮等,从结构上看,有平行轴的、垂直轴的交错轴的以及输入输出在同轴的等许多种类,用于改变转角或转速,轴的位置等。一方面,随着电子技术的进步,开发了可控硅电动机等,采用由各种调速电动机直接驱动的方式增多了。进而开发了使用滚子、圆盘等的各种摩擦传动装置,油压驱动装置以及汽车用自动变速机等,代替过去齿轮装置的动力传动装置。特别是润滑和润滑技术的发展,摩擦传动装置的进步显著,当转速变换精度要求不高,并允许传递扭矩有小变动和微小的滑动损失时,如小型透平用减速机,摩擦传动装置的使用将会增加。但是,为了减小驱动回转体的惯性,便于控制,而使装置小型化,所以也有将
1, Overview of Gear Manufacturing Gear and gear units, like bearings and bolts, are indispensable and important parts for all kinds of machinery and devices such as industrial machinery, automobiles, ships, locomotives and aircraft. Gear and gear devices have cylindrical gears, bevel gears, worm gear, helical gears, etc., from the structure point of view, there are parallel axis, the vertical axis of the staggered axis and the input and output in the coaxial and many other types used to change the corner or Speed, shaft position and so on. On the one hand, with the progress of electronic technology, the development of SCR motor, etc., by a variety of speed motor direct drive increased. In addition, various types of friction transmission devices, such as a roller and a disc, a hydraulic drive device, and an automatic transmission for automobiles have been developed to replace the conventional power transmission device. In particular, the development of lubrication and lubrication technology, the progress of the friction transmission significantly, when the speed is not high precision and allows small changes in torque transmission and slight sliding losses, such as small turbine reducer, friction transmission device Use will increase. However, in order to reduce the inertia of the driving rotary body and facilitate the control, the size of the apparatus is reduced. Therefore,
