減速機(jī)技術(shù)資料：

減速機(jī)在生活中用到的地方越來(lái)越多，本文淺析活齒減速器結(jié)構(gòu)與傳動(dòng)原理。活齒減速器結(jié)構(gòu)與傳動(dòng)原理活齒減速器各部件的運(yùn)動(dòng)分析如下。
激波器為輸入裝置，保持架為輸出裝置，中心輪固定不動(dòng)。偏心激波器繞偏心點(diǎn)旋轉(zhuǎn)，滾子在保持架中自轉(zhuǎn)并繞偏心點(diǎn)B轉(zhuǎn)動(dòng)，在滾子轉(zhuǎn)動(dòng)過(guò)程中滾子與激波器始終相切，即滾子幾何中心與激波器的幾何中心之間的距離保持不變，而滾子的幾何中心與偏心點(diǎn)的距離一直在變化，由于中心輪固定不動(dòng)，并且與滾子始終接觸。
因此其輪廓形狀為滾子沿滾子中心運(yùn)動(dòng)軌跡形成的外包絡(luò)線。要求得中心輪的齒廓，就要先求滾子軌跡的曲線方程。對(duì)于滾子沿軌跡產(chǎn)生的包絡(luò)線是以理論軌跡為中心，滾子半徑和激波器半徑的關(guān)系與外擺線不同，不存在整數(shù)倍關(guān)系，這有利于更加靈活地設(shè)計(jì)減速器，便于減小減速器的重量和體積。
滾柱隨活齒架的轉(zhuǎn)動(dòng)的轉(zhuǎn)角呈周期性變化，在一個(gè)周期中，相對(duì)速度由小變大、由大變小、由小變大、再由大變小四次變化，出現(xiàn)了兩個(gè)極大值和一個(gè)極小值。活齒中心運(yùn)動(dòng)軌跡的曲率中心輪齒廓曲線的曲率，表示該點(diǎn)附近齒廓曲線的彎曲程度，它描繪了齒廓曲線的幾何特征，是研究活齒傳動(dòng)承載能力、潤(rùn)滑狀態(tài)等所依據(jù)的重要參數(shù)。中心輪齒根處曲率最大，曲率半徑最小;沿齒廓上升過(guò)程中曲率減小到零，繼續(xù)減小到負(fù)值。
在強(qiáng)度校核中也可根據(jù)曲率半徑來(lái)使計(jì)算結(jié)果更加趨于實(shí)際。活齒傳動(dòng)的滑動(dòng)率了解滑動(dòng)率的特點(diǎn)有助于開(kāi)發(fā)磨損小、壽命長(zhǎng)、嚙合效率高的減速器。齒形的磨損規(guī)律在一定程度上取決于齒廓在接觸點(diǎn)上相對(duì)滑動(dòng)速度的變化規(guī)律。
活齒減速器中心輪齒形求解的新方法，繪制齒形曲線，實(shí)現(xiàn)活齒傳動(dòng)設(shè)計(jì)的參數(shù)化。并由此繪制出速度曲線、曲率曲線、滑動(dòng)率曲線。由方程曲線的信息得到活齒傳動(dòng)各構(gòu)件的運(yùn)動(dòng)規(guī)律，為活齒傳動(dòng)進(jìn)一步研究打下了基礎(chǔ)。
