机械设计中渐开线花键联结参数选择计算比较麻烦,这里介绍用微机程序运算可在极短时间内求得满足强度条件的最小模数和最少齿数值。一、计算公式:花键的挤压强度:σ_ρ=T/ψ·z·h·l·r_m≤[σ]_ρ式中:T—传递扭矩(kgf·mm)ψ—载荷分布不均系数一般ψ=0.7～0.8z—齿数l—花键齿工作长度(mm)r_m—花键平均半径(mm)r_m=1/2mzh—花键齿工作高度(mm)h=md_f—分度圆直径(mm)m——模数(mm)
Mechanical design involute spline connection parameter selection calculation is too much trouble, here introduced by the computer program can be calculated in a very short period of time to meet the conditions of strength to meet the minimum modulus and the minimum number of teeth. First, the calculation formula: Spline compression strength: σ_ρ = T / ψ · z · h · l · r_m ≤ [σ] _ρ Where: T-transfer torque (kgf · mm) ψ- load distribution Uneven coefficient ψ = 0.7 ~ 0.8z- Number of teeth l- Spline tooth working length (mm) r_m- Spline average radius (mm) r_m = 1 / 2mzh- Spline tooth working height (mm) h = md_f- mm) m - modulus (mm)
