Date: 1981-07-01
Description: ESDU 77002 provides data for geometric gear design for gear ratios up to 10:1. Guidance on the choice between spur and helical gears is provided by considering the factors of noise, end-thrust and cost.
AGMA 08FTM19 - HOW ARE YOU DEALING WITH THE BIAS ERROR IN YOUR HELICAL GEARS? Organization: AGMA
Date: 2008-10-01
Description: Using illustrations this paper explains that bias error ("the twisted tooth phoneme") is a by-product of applying conventional radial crowning methods to produced crowned leads on helical gears. The methods considered are gears that are finished, shaped, shaved, form and generated ground.
AGMA 97FTM14 - REFINEMENTS IN ROOT STRESS PREDICATIONS FOR EDGES OF HELICAL GEAR TEETH Organization: AGMA
Date: 1997-11-01
Description: Three dimensional FEA, although reliable, is time consuming and of great expense in comparison to the use of classical techniques and approximations. In helical gears these approximations give reasonable estimates of root stress distributions along the face width but lack the accuracy to design to engineering limits.

Date: 2011-10-01
Description: For spur gears with no helix angle the interpretation of the measurements to a face load factor is intuitively easy. For helical gears, more frequently used in big gearboxes, the determination of the factor gets tougher.
