蜗轮啮合效率的普遍表示式为:η=tanλ/(tan(λ+ρ′))……………………(1)根据白金汉(Earle Buckingham)的推导结果,蜗轮啮合效率的表示式为:η=sin2λ/(sin2λ+2f′)……………………(2)式中:λ——蜗杆节圆柱处螺旋线的升角ρ′——相当摩擦角ρ′=tan~(-1)f=tan~(-1) f/cosα_n
The general expression of worm gear meshing efficiency is: η = tanλ / (tan (λ + ρ ’)) (1) According to the derivation result of Earle Buckingham, Is: η = sin2λ / (sin2λ + 2f ’) (2) Where: λ - helical pitch angle of the helical pitch cylinder ρ’ - equivalent friction angle ρ ’= tan ~ (-1) f = tan ~ (-1) f / cosα_n
