摘　　要：提出一种新的齿面接触分析方法,首先以"黄金比例法"找出齿面接触点,并以所求得的齿面接触点参数计算大齿轮的角度传递误差;接着以该接触点的切向量为基准通过搜寻法找出接触齿印,从而求解出边界接触条件下的齿轮副接触状况;最后以Litvin的齿面接触分析方法为参考,验证文中所提出的齿面接触分析方法的正确性。In this article,a new method for the tooth-contact analysis was proposed. Firstly,the golden-ratio method is adopted to identify the contact point on the tooth surface,and the big gear’s angle-transfer error is worked out with the aid of the related parameters. Then,based on the contact point’s tangent vector,the contact ellipse is found by means of the searching method,and the contact condition of the gear’s pair characterized by boundary contact is solved. Finally,the Litvin tooth-contact analysis was adopted to verify that the above-mentioned tooth-contact analysis is correct.
