 重量計算公式

                            

圓柱體重=直徑×直徑××0.0062 

四角體重=長×××0.00785 

六角體重=對邊×對邊××0.866 

1
 其它材料的計算公式

 
=鐵重×0.00275 白鐵=鐵重×1.05 

黃銅=鐵重×1.08 紅銅=鐵重×1.14 

矽銅=鐵重×1.10

牙底徑和碾造徑算法: 

算法一:1 

公制H=0.866025*P-

H1=0.541266*P 

碾造直徑公式: D-(0.1443*p0.6495*p) 

例如:M40.7 3.95-(0.1443*0.7 0.6495*0.7)=3.4 

備注:鋼牙螺絲取其牙距2/3 

英制:H=0.866025/nn*25.4 H1=0.541266/nn*25.4 D2=D0.640519/nn*25.4 D1=D1.082532/nn*25.4 

線徑:D-(0.13733*P0.6433*p) 

例如:5/3232 3.96-(0.13733*0.790.6433*0.79)=3.34 

H:
牙峰高度;

P:牙距;

H1:實用牙高;

D2:中徑;

D1:實用牙底徑;

D:名稱徑;


中徑: D2=d2 d2=D2*3H/8 H= 0.866025p (60度牙山) H=0.960491P
