多年来,发明人在从事系列抽油机减速器设计和圆弧齿轮传动研究的基础上,研究设计了一种新颖的双向圆弧齿轮传动,即双重凸凹啮合圆柱齿轮传动。这种新颖的齿轮传动己获国家发明专利,其特征在于齿轮法截面内齿廊为双圆弧齿形,而在节圆展开后平面内齿线为圆弧齿线,可充分发挥齿高和齿长两个方向凸凹啮合的优越性;改善齿面结构, Over the years, the inventor engaged in a series of reducer design and arc gear drive based on the research, designed a novel two-way circular arc gear drive, that is, double convex and concave meshing spur gear transmission. This novel gear drive has been the national invention patents, which is characterized by a gear tooth cross-section of double-arc arc tooth profile, and after the expansion of the pitch circle in-plane gear teeth arc lines, tooth height can be fully demonstrated and The advantages of convex and concave meshing in both directions of tooth length; improving the structure of tooth surface,
