一、绪言众所周知,由齿轮传递动力的目的有两个,一个是进行定角速比的动力传递,另一个是改变回转方向连续地进行动力传递。一般认为,应该是彼此直接接触的刚性齿轮才能传递动力。如果不使齿面直接接触就不能传递动力吗?人们会产生这样的疑问。直到现在人们在坚持齿轮的啮合 First, the introduction As we all know, the purpose of the power transmission gear through two, one is the angular velocity ratio of power transmission, the other is to change the direction of rotation for power transmission. It is generally believed that a rigid gear should be in direct contact with each other to transmit power. If you do not make direct contact with the tooth surface can not pass power? People will have this question. Until now people are insisting on gear meshing
