1.承载能力计算的追溯 1.1一般历史的回顾直到18世纪中叶人们对于齿轮感兴趣的主要在于其运动学和几何关系。当18世纪末铁质齿轮使用后,才开始注意到强度和承载能力。为了使磨坊中传动的铸铁齿轮或锻造齿轮的尺寸大小足以保证不断齿的要求,需要有一些设计方法。此后,开始研究了齿轮的摩擦磨损,点蚀形成和胶合磨损。这里简要的罗列一些在那时颇有意义的进展。 1. Traceability of Carrying Capacity Calculation 1.1 General History Review Until the mid-18th century people were interested in gears mainly in their kinematics and geometry. When the iron gear was used at the end of the 18th century, strength and load bearing capacity began to be noticed. In order to make cast iron gears or forged gears in a mill sized enough to ensure constant tooth requirements, some design methods are required. After that, he began to study the friction and wear of gears, pitting formation and cementing wear. Here is a brief list of some meaningful developments at the time.
