引言将电磁离合器和齿轮副互相搭配,组成有级的自动或负荷下变速的基本传动组,具有结构紧凑、效率高、适应性强、成本低和可得到精确定速比传动以及自身能实现制动等优点,至今在一些机床的主传动系统中仍得到广泛的应用。当前,虽然AC或DC可调速电机、多速电机和各类机械无级变速器的应用日益增多。但是用电磁离合器来实现自动变速的方案,在一些特定场合仍有使用价值。本文主要对布置在两个平行轴线上的双轴自动变速基本组的情况,给出几种可行而实用的搭配方案。一、基本组的变速范围和转数间隔可预
Introduction Electromagnetic clutches and gear pairs with each other to form a grade of automatic or load-shifting under the basic drive group, with a compact, high efficiency, adaptability, low cost and can be precise speed ratio than the drive and its own system can be achieved Moving and other advantages, so far in some of the main drive system of the machine is still widely used. At present, although AC or DC adjustable speed motors, multi-speed motors and various types of mechanical continuously variable transmission applications are increasing. However, the use of electromagnetic clutches to achieve automatic transmission program, there are still some cases of use value. In this paper, mainly on the two parallel axes arranged on the two-axis automatic transmission basic group case, gives several feasible and practical with the program. First, the basic group of variable speed range and speed can be pre-interval
