Hi!(adsbygoogle = window.adsbygoogle || []).push({});

I'm stuck on a very basic problem while trying to design a product. Basically, I need to know how to calculate the gear ratios, pitch, motor specs etc for two rack and pinion mechanisms- one horizontal and one vertical. The pinion moves along the rack in both situations.

Mass to be moved- 140 kg

speed- 0.3m/s

Distance: Horizontal- 0.65 m, and vertical- 0.45 m

I realise this is quite a simple problem, but I'm have trouble figuring out the best way to go about calculating the specs. Could anyone tell me a basic route to go down- what steps to take in order to give me an approximate specification for my product? Any links would be helpful.

Many thanks
