Gear Technology Magazine Article on Modelling Transmission Error featuring Analysis of High Contact Ratio Gears

Gear Technology has recently published an article named “Evaluation of Methods for Calculating Effects of Tip Relief on Transmission Error, Noise and Stress in Loaded Spur Gears” derived from the technical paper presented at the AGMA Fall Technical Meeting. The paper illustrates the principles of transmission error modelling. It also describes the differences to expect when opting for different types of mathematical models. The graphics show clearly why the same gear will require a different extent as well as amount to optimise performance at a given load, and that different gears will require a different relief strategy. It has an analysis of High Contact Ratio (HCR) gears and highlights some pitfalls to watch out for when opting for this type of gear and applying tip relief.

Dontyne to Exhibit at IPTEX 12, Mumbai, India

We are looking forward to meeting many new customers at the IPTEX 12 show in Mumbai, India, February 9-11 2012. This will be a good chance to build on the excellent show held by AGMA in Cincinnati where the overwhelming interest in our software was pleasing. The discussions were interesting and the contacts told us repeatedly how they were impressed that the software was simple to use and and affordable. It was especially effective in the area of manufacturing by helping to quickly analyse the effect of manufacturing on rating and operating characteristics. This would be equally applicable to gear production in India and so would like to invite interested parties to discuss your requirement at Booth A25. If you would like to discuss any issues in advance of the show please contact us using
