摘要:

迴轉動力為機械主要的動力源，因此將迴轉運動轉換為具快速、高精度及節能之可變直線往復運動為機械設計重要課題。故本文提出運用泛用型減速機馬達為動力源，驅動曲柄搖桿四連桿機構，並將其輸出動力之搖桿軸連接至增速機之輸入軸，再由增速機之輸出軸，所輸出連續正逆轉之迴轉動力驅動導螺桿的方法，求得導螺桿驅動滑塊移動具急回、近對稱等多可變運動性能曲線之輸出。本研究並以實作及實驗的方式，驗證本研究可變運動性能曲線之直線往復運動機構的運動性能及其實務製作的可行性。

Rotary motion has been the fundamental mechanism of most machines. It is considered important in mechanical design to convert the rotary motion into a variable reciprocating linear movement characterized as fast, high precision and energy saving. The study proposes to employ a universal reducer motor to provide mechanical energy to drive the crank-rocker mechanism in which the shorter side link revolves and the other one rocks in the four bar linkage. The crank shaft that transfers energy is connected to the input shaft of an increaser. The guide screw is then started by the continuous forward and reverse motion from the output shaft of the increaser to drive the slide. The study obtains the output of a variable performance curve in sport that is nearly symmetrical and ensures a quick return. This is an implementation and experimental study to verify the sport performance of the reciprocating mechanism of a variable performance curve in sport and its feasibility of practical production.
