Where: Rvk :Tip diameter on back cone for equivalent spur gear (mm) Rvk = Rv + hk = r0secδ0 + hk Rvg :Reference radius on back cone for equivalent spur gear(mm) Helical gears = Rv cosα0 = r0secδ0 cosα0 Spiral bevel gears ＝ Rv cosαs = r0secδ0 cosαs Rv :Back cone distance(mm) = r0secδ0 r0 :Pitch radius(mm) = 0.5z m hk :Addendum at outer end(mm) α0 :Reference pressure angle (degree) αs :Mean transverse pressure angle (degree) = tan–1(tanαn/cosβm) αn :Reference normal pressure angle (degree) Table 10.17 The transverse contact ratio for Gleason’s straight bevel gear, εα (Σ = 90°、α0 = 20°) Table 10.18 The transverse contact ratio for standard straight bevel gear, εα(Σ = 90°、α0 = 20°) Table 10.19 The transverse contact ratio for Gleason’s spiral bevel gear, εα(Σ = 90°、α0 = 20°、βm = 35 deg) (3)-4 Spiral Angle Factor, Yß The spiral angle factor, Yß, is obtainable from Equation (10.39)
NVG50 Manual The NVG50 was slightly updated in May 2025 to include a new lens and firmware and the performance and view is very slightly different.
