Establishing a gear design, that is fit for purpose and cost effective, is a specialised task. Lamond and Murray have invested in Dontyne systems Gear Production Suite (GPS) to allow us to offer a gear design service to our customers. GPS applies the ISO 6336 standard to rate spur and helical gears; it allows rapid comparison of different geometry and material configurations, helping the designer establish a suitable and cost effective solution. When verifying a design both gears can be modelled running together, possible design problems can therefore be spotted and eliminated at an early stage. For example the gear designs shown below have identical numbers of teeth, pitch and centre distance, however, the corrected gears have superior gear geometry, will last longer and will be cheaper to make!
