甚么是弧齒圓柱蝸桿傳動(dòng)?a@b.com (realnew)http://www.candadevelopment.com/boke/post/11.htmlFri, 18 Nov 2011 17:17:27 +0800http://www.candadevelopment.com/boke/post/11.html        弧齒圓柱蝸桿傳動(dòng)是一種蝸桿軸面或法面齒廓為凹圓弧與蝸輪齒廓為凸圓弧的蝸桿傳動(dòng)。在這種傳動(dòng)中,干戈線與絕對(duì)滑動(dòng)速度之間的夾角較大,故易于形成潤(rùn)滑油膜,而且凸凹齒廓相嚙合,干戈線上齒廓當(dāng)量曲率半徑較大,干戈應(yīng)力較低,是以其承載技巧與屈就均較其它圓柱蝸桿傳動(dòng)為高。

蝸桿傳動(dòng)的首要參數(shù)a@b.com (realnew)http://www.candadevelopment.com/boke/post/10.htmlFri, 18 Nov 2011 17:16:50 +0800http://www.candadevelopment.com/boke/post/10.html    蝸桿傳動(dòng)的參數(shù)和幾何尺寸計(jì)較大體與齒輪傳動(dòng)相似。蝸桿傳動(dòng)的主要參數(shù)有:
    蝸桿的軸向齒距pX應(yīng)與蝸輪的端面周節(jié)pt相等,是以蝸桿的軸向模數(shù)應(yīng)與蝸輪的端面模數(shù)相等,以m表現(xiàn),m應(yīng)取為標(biāo)準(zhǔn)值。蝸桿的軸向壓力角應(yīng)就是蝸輪的端面壓力角,以α表現(xiàn),一般標(biāo)準(zhǔn)壓力角α=20°。   蝸桿相等于螺旋,其螺旋線也分為左旋和右旋、單頭和多頭。一般蝸桿的頭數(shù)Z1=1~4,頭數(shù)越多服從越高;但頭數(shù)太多,如Z1>4,分度弊病會(huì)增大,且不易加工。蝸輪的齒數(shù)Z2=iZ1,i為蝸桿傳動(dòng)的傳動(dòng)比,i=n1/n2=Z2/Z1。對(duì)于一般傳遞動(dòng)力的蝸桿傳動(dòng),Z2=27~80。當(dāng)Z2<27時(shí),蝸輪齒易打造生根切;而Z2太大時(shí),籠統(tǒng)招致蝸輪齒彎曲強(qiáng)度不敷。

蝸桿傳動(dòng)的共計(jì)準(zhǔn)則a@b.com (realnew)http://www.candadevelopment.com/boke/post/9.htmlFri, 18 Nov 2011 17:15:33 +0800http://www.candadevelopment.com/boke/post/9.html  目前關(guān)于蝸桿傳動(dòng)的膠合與磨損,咱們還不有童稚的算計(jì)方法。
    齒面接觸應(yīng)力是引起齒面膠合與磨損的緊要成份,于是仍以齒面接觸強(qiáng)度算計(jì)為蝸桿傳動(dòng)的根本算計(jì)。
    其它,偶爾還應(yīng)驗(yàn)算輪齒的筆直強(qiáng)度。一般蝸桿齒不簡(jiǎn)單松弛,故通常不必發(fā)展齒的強(qiáng)度算計(jì),但重要時(shí)應(yīng)驗(yàn)算蝸桿軸的強(qiáng)度與剛度。
    對(duì)閉式傳動(dòng)還應(yīng)發(fā)展熱平衡算計(jì)。假定熱平衡算計(jì)不克不及不滿申請(qǐng),則在箱體外側(cè)加設(shè)散熱片或采用逼迫冷卻裝置。

什么是平庸圓柱蝸桿?a@b.com (realnew)http://www.candadevelopment.com/boke/post/7.htmlFri, 18 Nov 2011 17:12:56 +0800http://www.candadevelopment.com/boke/post/7.html    蝸桿是指存在一個(gè)或幾個(gè)螺旋齒,并且與蝸輪嚙合而組成交錯(cuò)軸齒輪副的齒輪。其分度曲面或許是圓柱面,圓錐面或圓環(huán)面。
    尋常圓柱蝸桿的齒面,除ZK型蝸桿外,通常是在車床上用直線刀刃的車刀車制的。
    按照車刀安裝位子的不同,所加工出的蝸桿齒面在不同截面中的齒廓曲線也不同。按照不同的齒廓曲線,尋常圓柱蝸桿可分為阿基米德蝸桿(ZA蝸桿)、漸開線蝸桿(ZI蝸桿)、法向直廓蝸桿(ZN蝸桿)與錐面包絡(luò)圓柱蝸桿(ZK蝸桿)等四種。
