KISSsoft and Geartech Jointly Develop New Software Program
KISSsoft AG and GEARTECH Software are pleased to announce the introduction of a new and updated version of GEARCALC, a gear design program originally released in 1986.
GEARTECH Software has been providing rating programs for spur and helical gears since the 1984 release of AGMA218, the first commercial product to comply with the AGMA standard of the same name. Using techniques introduced by GEARTECH founder Robert Errichello, this program was later updated to include analyses of wear and scuffing probabilities (SCORING+ in 1985) and preliminary sizing routines (GEARCALC in 1986) into one seamless package.
GEARCALC requires a minimal input data and prompts the user to input the application, load, material, and heat treatment data for a gearset.
GEARCALC designs maximum-capacity gearsets that have minimum volume and weight. Profile shift coefficients can be selected to maximize pitting and wear resistance, scuffing resistance or bending strength.
AGMA 2001, which replaces AGMA218, rates gears exactly as intended by the American Gear Manufacturers Association Standards:
"ANSI/AGMA 2001-D04 and ANSI/AGMA 2101-D04, “AMERICAN NATIONAL STANDARD, Fundamental Rating Factors and Calculation Methods for Involute Spur and Helical Gear Teeth.”
AGMA 2001 performs the following analyses:
Life Rating – Given the transmitted power and speed, the pitting life and bending fatigue lives are calculated for a single load and speed, or for an entire spectrum of loads and speeds with the resultant lives determined from Miner’s Rule.
Power Rating – Given the pinion speed and required design life, the allowable transmitted power based on gear tooth pitting and bending fatigue is calculated for both the pinion and gear. The allowable power rating of the gearset is the minimum of the four power capacities.
AGMA 925, which replaces SCORING+, rates gears exactly as intended by the American Gear Manufacturers Association Information Sheet:
AGMA 925-A03, “AGMA Information Sheet, Effect of Lubrication on Gear Surface Distress.”
AGMA 925 performs a complete analysis of the tribology of spur and helical gears. It calculates the EHL film thickness using the Dowson and Toyoda equation and the flash temperature using Blok’s critical temperature theory.
AGMA 925 features include:
Calculates EHL specific film thickness and probability of wear
Calculates total contact temperature and probability of scuffing
Calculates rolling, sliding, and entraining velocities, and specific sliding (slide/roll) ratios
Calculates Hertzian contact stress
Provides screen and hard-copy plots of specific sliding, Hertzian stress, film thickness, specific film thickness, and contact temperature
Programs GEARCALC, AGMA 2001, and AGMA 925 work together in a seamless integrated system that has been optimized using state-of-the-art technology to simplify gear design and analysis.
The software is available as a stand-alone package, or integrated into the CAD programs Inventor, Solid Edge, SolidWorks and Pro/E.
