摘要
正齿行星轮分插机构是一种新型高速分插机构,由椭圆齿轮传动部分、正齿轮行星轮传动部分和栽植臂组成。其设计的基本思想采用椭圆齿轮副传动,选择合适的结构参数来形成插秧要求的非匀速传动比及转角关系。为此,主要论述如何利用计算机确定分插机构中椭圆齿轮的几何参数、椭圆齿轮副的传动性质,以及轮齿的齿廓在啮合过程中能保证要求的转动比、合适的压力角等。
Separating-Planting Mechanism with Planetary Gears of Non-Eccentricity is a new-type mechanism. The mechanism is constituted by three parts, they are oval gear transmission division, planetary gear transmissi on division and plant the arm. Basic thought of designing is adopting oval gear transmission, choicing the fit construction parameter to ensure Asymmetry transmission ratio and screw the angle relation of the request of transplant rice seedling. The thesis will expatiate how to computer geometric paremeter of oval gear,analysis transmission character of oval gear, and ensure transmission ratio and Angle of pressure in the period of Engagement of oval gear,
