摘要

本文提出兩齒差滾子傳動(Roller drives)減速機系統化的幾何設計方法，並做嚙合特性分析，進而使用CAM做加工製造模擬以利未來在CNC之加工製造。本文利用CAD建構實體模型，以驗證此系統化幾何設計方法之可行性。由嚙合特性分析可知，當行星輪滾子擺放在嚙合件共軛齒廓之齒頂時，會得到較佳之嚙合傳動；若設計參數( , , )不變時，則兩齒差比一齒差之滾子傳動減速機可獲得較佳之嚙合運動；當固定速比時，若 值愈大，則在傳動時較為平順；兩齒差滾子傳動減速機，當圓柱嚙合件齒數愈多時，同時會有愈多齒作嚙合運動。本研究可提供CAD/CAM之整合模式，進而作為未來人機界面發展之先期作業參考模式。

This work presents a method on geometric design of roller drives with two teeth difference, and makes the analysis of meshing characteristics, then will use CAM to make the processing manufacture simulation in order to help processing manufacture on the CNC in the future. This work uses CAD to construct the solid modeling, confirms feasibility of the systematized geometric design method. By the analysis of meshing characteristics it is known, when rollers of the planet gear place to the top of the gear on the conjugate tooth profile, can obtain good gearing. If the design variable ( , , ) is invariable, roller drives with two teeth difference may obtain better mesh with the movement than roller drives with one. When fixed velocity ratio, if is bigger, transmission is smooth. Roller drives with two teeth difference, when the number of cylindrical meshing rollers is more, simultaneously can have more teeth to do meshes with the transmission. This research may provide conformity of the pattern on the CAD/CAM, and will take the man-machine interface development ahead of time the work reference pattern in the future.
