摘　　要：用霍尔元件代替旋转编码器测量主轴转速 ,适用于无法安装旋转编码器的设备或转速范围特别大的系统 ,目前已成功应用于宝钢钢管分公司石油钻杆摩擦焊机上。其特点是采用单片机系统对摩擦焊过程中的瞬时速度及压力、焊接缩短量作 0 1s间隔的定时采样和储存 ,并通过RS -2 32串行通信方式传送到上位PC机 ,进行显示、记录或打印。This paper advances the new method using Hall Effect device to measure the speed of spindle,instead of using the traditional method by counting Rotory Encoder pulse,is appropriated for those equipment which can't be equipped with Rotory Encoder or the systems with especially wide range of speed.This measuring system has been successfully applied on the friction welding machine for oil drill pipe in Baosteel.The Hall Effect device features that a single chip micro computer can be used to make timing measurement and stored the instant parameters,at intervals of 0.1 second,such as the speed of spindle,pressure,shrintage of welding,etc.,in the welding process.These parameters are transmitted to up side PC by RS-232 series communication to display record or print.
