鏈輪的基本套用及其他
鏈輪的套用：被廣泛套用於化工、紡織機械、食品加工、儀表儀器、石油等行業的機械傳動等
鏈輪參數計算公式：
分度圓直徑:d=p/sin180°/z p=節距可查表 z=齒數
齒頂圓(外徑):D=p×(0.54+cot180°/z)
給你常用鏈輪節距你自已算算,不明白再問我
3/8=9.525 1/2=12.7 5/8=15.875 3/4=19.05
3分 4分 5分 6分
分度圓直徑：d=p/sin（180°/z）
齒頂圓直徑：dmax=d+1.25p-d1
dmin=d+（1-1.6/z）p-d1
齒根圓直徑：df=d-d1
註：p 鏈條節距
z 鏈輪齒數
d1 鏈條滾子直徑
鏈輪型號：包含非標鏈輪（根據客戶圖紙定製），標準鏈輪（美標和公制）。
鏈輪常用材料：C45
鏈輪常用加工方法：淬火處理，表面發黑處理。
