2、理,推導(dǎo)了基于全齒寬嚙合的漸開線弧齒圓柱齒輪的精確齒面和過渡曲面方程,通過MATLAB軟件編程計(jì)算出弧齒圓柱齒輪的凹齒面、凸齒面及過渡曲面的坐標(biāo)點(diǎn),將計(jì)算得到的點(diǎn)云導(dǎo)入三維實(shí)體建模軟件,經(jīng)過簡單處理生成精確弧齒圓柱齒輪的三維實(shí)體模型。最后,通過數(shù)值解法計(jì)算了漸開線弧齒圓柱齒輪的真實(shí)嚙合情況,并用可視化界面顯示齒面接觸曲線。結(jié)果表明該齒輪是關(guān)于齒輪中間截面對稱的全齒寬嚙合弧齒圓柱齒輪;輪齒在進(jìn)入和退出嚙合時是部分齒面接觸。關(guān)鍵詞:全齒寬嚙合;弧齒圓柱齒輪;嚙合特性;MATLAB;參數(shù)化設(shè)計(jì)中圖分類號:TH132.41;TG65搖搖搖文獻(xiàn)標(biāo)識碼:AParametricDesigna
