The addendum circle may separate, the assembly is easy. 外圈可分离，组装容易。
From the very beginning I rose several positions, bent in 2 from the addendum circle has surpassed Vetter. 一开始我就上升了好几个位置，在2号弯从外圈超过了维特尔。
This paper deals with measuring the diameter of addendum circle for a involute spur cylindrical gear and calculating and determining its mode number and pressure angle. 本文阐述了渐开线直齿圆柱齿轮齿顶圆直径的测量与齿轮模数、变位系数、压力角等参数的确定方法和步骤.
This paper designs a measuring instrument which can measure addendum circle and dedendum circle diameter of odd-tooth gears and can define all main parameters of gears. 设计了一种测量工具,用以测量奇数齿齿轮的齿顶圆和齿根圆直径,以便确定齿轮的主要参数。
The spot erosion of pinion is between the dividing circle and the root circle.The spot erosion of gear is between the dividing circle and addendum circle. 小齿轮点蚀发生在分度圆与齿根圆之间，大齿轮点蚀发生在分度圆与齿顶圆之间。
Then,on gained curves of addendum circle,dedendum circle and saucer shape,the reason and solution for the above mentioned problems are provided and the gualified friction disks are produced. 然后再根据实验过程中获得的齿顶圆、齿根圆及碟形量变化曲线,分析其产生原因并提出了解决成形过程中变形问题的措施,已制造出符合质量要求的摩擦片精冲件。
