Spur gear transmissions are inherently noisy. I think that is why helical gears exist. However they typically have higher load capacity for the same width of gear (as I recall). I have a camshaft drive in a hotrod engine that was sold as a noisy gear drive and it is. It sounds like a supercharger. I need to replace it. It makes it difficult to hear what else is going on in the engine.
