Dontyne establishes new North American support facility

Dontyne Systems has recently established a North American support facility. We would like to announce the opening of the Cincinnati Ohio based facility effective December 15th, 2012. The support office will be managed by Mr. Rich Easley and support the company’s business throughout North America. Continued growth of our installed customer base, combined with increasing product interest has made this expansion necessary. Rich has nearly 30 years’ experience in engineering design, project management and customer support. His team in the US will provide excellent support to Dontyne’s North American growth. The Dontyne North American office may be contacted by telephone at 513-679-0313 or email at namerica@dontynesystems.com.

Dontyne to Develop Convoloid® LTCA with Genesis Partners

Dontyne Systems has entered into an agreement with Genesis Partners to develop software for the tooth contact analysis of their Convoloid® gear form. Convoloid is a conformal and conjugate gear tooth form exhibiting much lower contact stresses and improved bending strengths compared to its involute equivalent in size, centre distance and face width yet its manufacture is compatible with the world’s existing gear manufacturing infrastructure. The type of analysis available will be analogous to the involute helicoid analysis tools in the Gear Production Site. Genesis Partners have demonstrated in testing that this form of gearing has significant benefits over involute helicoid equivalent by direct testing in Wind Turbine gearboxes. There will be regions within the envelope of operation of any application where either involute helicoid or Convoloid would be a better selection. The new software will enable a cost effective analysis to identify optimum choice for testing. Just as with Dontyne’s involute helicoid equivalent there will be links to manufacturing and inspection for efficient production. The Convoloid type of analysis will be exclusive to Dontyne and will be available for testing in March.

Renishaw plc and Dontyne Systems Collaborate on Gear Metrology Systems

Renishaw continually develops its MODUS metrology software application to meet the demanding requirements of customers in a global market. A joint development with Dontyne Systems has resulted in the release of ‘MODUS Gear’ and ‘MODUS Spline’ software.

Seminar on Gears and Bearings 4th & 5th September

HeythropParkResortDontyne and MESYS AG are hosting a joint Seminar on Gears and Bearings in the beautiful setting of Heythrop Park Resort, Oxfordshire, UK. The Seminar is spread over 2 days and will look at software tools for the design and analysis using International Standards and Custom tools. The influence of manufacturing on rating and performance is considered, and practical methods to optimise performance. There will be a chance to discuss current design practices and try newly developed software products from both companies. Download the registration form to reserve a place or contact Clare Knight using uk@dontynesystems.com

Mike Fish elected to the British Gear Association Executive Council

We are pleased to report that Mike Fish has been elected to the Executive Council of the British Gear Association. This enforces Dontyne’s commitment to the BGA in the support of the gear industry in the UK. With Dr. Palmer and Dr. Fish both benefiting from BGA course in their carer development, it is a real privileged to be invited to participate at this level and Dontyne is looking forward to contributing to the development of engineers of the future. This adds to recent commitments to the working groups for ISO on various subjects such as load capacity for cylindrical gears, worm gears, and gear measurement.

Dontyne presentation on “Testing of Convoloid® Gear Forms in Wind Turbine Applications ” at GIG Seminar, Denmark

Dontyne was once again privileged to present to a sizeable and knowledgeable forum of companies involved in wind power generation at the hosted by Gearteknisk InteresseGruppe (GIG) at the University of Southern Denmark . This time the theme was testing. Although Dontyne has no testing equipment, we were able to present on the theme through collaboration with Genesis Partners in the USA. The Abstract is shown below.

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.
