本文论述了普通V带传动的发展概况以及设计方法。对两种典型的普通V带传动设计方法进行了分析研究,认为按滑动曲线设计法中以绕转数考虑带的寿命过于粗略;国际标准化组织推荐的方法(ISO370),虽然在计算中引入了由疲劳寿命试验决定的许用应力,但试验方法和试验条件不详,无法得到不同材质结构带的许用应力。在处理寿命和打滑的关系方面,认为按不打滑和预期使用寿命设计带传动方法(简称分立设计法)更合理。然而这种
This article discusses the general V-belt drive development and design methods. Two typical V-belt drive design methods are analyzed and studied, and it is considered that the life span of the belt is too rough considering the revolving number in the slip-curve design method. Although ISO370 is recommended by the International Organization for Standardization The allowable stress is determined by the fatigue life test. However, the test methods and test conditions are not known and the allowable stress of structural strips with different materials can not be obtained. In dealing with the relationship between life expectancy and skidding, it is more reasonable to design the belt drive method (referred to as discrete design method) according to the non-skidding and expected service life. However, this
