一、概述为了适应机械工业发展的需要,国外从五十年代开始研制和使用一种新型的带传动,即同步带(亦称齿形带、准时带等)传动。我们起步于六十年代,至今已有二十几年的历史了。近几年来由于机械工业的发展和引进设备的增多,同步带传动日益引起各方面的注意和重视。研究、生产和使用单位不断增加,应用范围也越来越广。目前在仪表、计算机和各类机械中得到应用。同步带传动是由一根内周表面设有等间距齿的封闭环形胶带和具有相应齿的带轮所组成,如图1所示。带的工作面是齿的侧面,工作时,胶带的凸齿与带轮
I. Overview In order to meet the needs of the development of machinery industry, foreign countries from the fifties began to develop and use a new type of belt drive, that is, timing belt (also known as a toothed belt, punctual belt, etc.) transmission. We started in the sixties, and we have twenty years history. In recent years due to the development of machinery industry and the introduction of more equipment, synchronous belt drive increasingly aroused the attention and attention of all parties. Research, production and use of units continue to increase, the scope of application is also more and more widely. Currently used in instruments, computers and various types of machinery. The timing belt drive consists of a closed endless belt with internal teeth on the inner peripheral surface and wheels with corresponding teeth, as shown in Figure 1. Belt face is the side of the tooth, work, tape teeth and pulley
