An example is given to introduce the application of the wheel design example as a deceleration mechanism in the electric regulator of the automobile rearview mirror. The example shows that the simplified formula provides the possibility for the rapid selection of the tooth number of gears in the mechanism, and is instructive to the structural optimization design of the mechanism.Key words: planetary gears; car rearview mirror目录中文摘要………………………………………………………………………………英文摘要………………………………………………………………………………1 绪论…………………………………………………………………………………. 1.1 研究背景及意义……………………………………………………………… 1.2 国内外研究现状………………………………………………………………1.2.1 大速比行星齿轮研究现状………………………………………………1.2.2 行星齿轮传动均载特性研究现状………………………………………2 大速比行星齿轮转动的特点和基本参数设计…………………………………… 2.1 大速比行星齿轮传动的特点………………………………………………… 2.2 大速比行星齿轮的效率和基本参数设计…………………………...
