Assumes standard involute helical gear teeth with zero profile shift (x1 = x2 = 0). Recommended helix angle range is 10° ≤ β ≤ 30°. Angles below 10° provide minimal overlap benefits; angles above 30° induce severe axial thrust forces. Axial thrust forces Fa must be reacted by appropriate tapered roller or angular contact ball bearings on the shaft. Calculations omit dynamic factor Kv, overload factor Ko, and mounting factor Km. For ISO 6336 full tooth rating, conduct detailed contact stress analysis.
How helix angle selection balances axial thrust loads against noise reduction and tooth bending capacity.
Key methodological differences between ANSI/AGMA 2001 and ISO 6336 gear stress verification.
