凸輪系列介紹: 輪,是一個具有曲線輪廓或凹槽的構件,一般可分為三類: (1)盤形凸輪:凸輪為繞固定軸線轉動且有變化直徑的盤形構件; (2)移動凸輪:凸輪相對機架作直線移動; (3)圓柱凸輪:凸輪是圓柱體,可以看成是將移動凸輪卷成一圓柱體。 按從動件的形狀分類;① 頂尖式從動件;② 滾子式從動件;圓柱凸輪間歇分度機構;③ 平底式從動件。④ 曲底式從動件。 按從動件的運動形式分類:① 直動從動件。② 擺動從動件; 按凸輪與從動件維持運動副接觸的方式分類:① 力封閉方式。② 幾何形封閉方式。 凸輪材料有:38CrMoAl氮化;20CrMnTi滲碳淬火;42CrMo淬火。凸輪淬火后需經過研磨內孔后再研磨曲線。
