摘要
传动副的标准设计常常出现传动元件的寿命不相等。通过传动元件的强度匹配,可有效解决此问题,从而提升齿轮传动寿命。从啮合原理出发,通过改变通常的标准设计参数,使得蜗杆副设计既能满足传动比及强度的要求,又能体现结构紧凑性,同时实现传动零件的啮合强度匹配。重点研究了两种参数修正方案:变模数及同时变压力角的方法,以及单一变齿厚的方法。实践证明了两种方法的可行性和有效性。
The life of transmission element is not equal often occurs in the standard design of the transmis- sion pair, this problem can be effectively solved through the strength matching of transmission element. Starting from the meshing principle, by changing the standard of usual parameters, which makes the design of worm pair can meet the requirements of transmission ratio and strength, but also reflects the structure compact, while the meshing strength matching of transmission parts is realized. The two parameter correction schemes： the method of variable modulus and pressure angle and variable, and the method of single variable tooth thickness are mainly studied. The feasibility and effectiveness of the two methods are proved by the practice.
