Special Presentations

An Analytical Model for Real-Time Design Evaluations of Spline Couplings - Yi Guo and Jonathan Keller, National Renewable Energy Laboratory and Robert Errichello, GEARTECH and Chris Halse, Romax Technology

Articulated spline couplings, often used in modern wind turbine gearboxes to connect the planetary and helical gear stages, are the key component in the floating sun configuration that equalizes the planetary load sharing.  Splines are critical because in addition to the outright failure of the sun spline itself, poorly functioning splines can lead to failures in the rest of the planetary stage because of their influence on load sharing characteristics. This work presents an analytical formulation for the analysis of articulated spline coupling designs. The formulation accounts for Hertzian, bending, and shear deformation and stresses of spline teeth.  The tooth contact and load distribution are calculated using a hybrid analytical-computational approach that considers tooth crowning.  Fatigue and yielding safety factors are calculated based on various heat treatment methods. For a given torque and shaft misalignment, the model calculates tooth contact, stiffness, stress concentration, and safety factors. The model allows a sensitivity analysis of spline loads, stresses, and safety factors to misalignment, transmitted torque, tooth crowning, and heat treatment. The analytical model results compare favorably with high-fidelity finite element analyses and quickly yield insights into relationships between the spline design parameters and resulting loads and stresses.

ISO 1328-1:2013:The New World Standards for Spur and Helical Gear Tooth Accuracy. What is New, and How it Differs from Previous Standards - John Rinaldo, Atlas Copco Comptec LLC

This presentation explains the new requirements in  ISO 1328-1:2013 as well as the differences from past AGMA and DIN standards.  The differences include changes in the range of gears included in the standard, what measurements are required, and how those measurements are made.  Numerous graphs are included showing how tolerances have changed as a function of both tooth and gear size.  The advantages to the purchaser will be discussed, as well as the advantages to the manufacturer.  All gear designers should be thinking about using this specification as part of all future gear designs, since not only is this the current ISO specification for tooth flank tolerance classification, it is now the AGMA standard and is also being adopted by DIN and JIS.

Applying AGMA Flexible Coupling Standards to the World of Gearing - Todd Schatzka, Rexnord

Flexible couplings are a critical component of a rotating equipment system.  Properly selected and maintained, a flexible coupling will contribute to or even improve the longevity of the connected equipment.  The AGMA Flexible Coupling Committee creates and maintains 13 standards and information sheets that contain valuable information to assist equipment designers and users.  This presentation will briefly describe each standard and information sheet and then highlight key features of individual standard that would be of particular interest to gearbox designers, manufacturers, and users.
