低速重载齿轮,在设计中有关弯曲应力或轮齿的抗断裂强度的计算是很重要的内容,而承载能力的计算又是以齿根当量应力为依据的。也就是说齿根应力沿齿向的分布情况在很大程度上决定了齿轮的承载能力,这就是我们研究齿根应力的出发点。齿根应力的大小及分布除了啮合角、齿数 Low-speed heavy-duty gear, in the design of bending stress or gear tooth fracture strength calculation is very important content, and carrying capacity is calculated based on root equivalent stress. That is to say, the distribution of tooth root stress along the tooth direction largely determines the carrying capacity of the gear. This is the starting point for our study of root stress. Dental root stress and size distribution in addition to meshing angle, the number of teeth
