This is outside of my area of expertise, which is why I making this post.
I'd like to replace a couple of spur gears that have worn out, but am not familiar with descriptive terminology. How may I determine what gears to order? I want to make sure I order equivalent parts. The originals are plastic, I am inclined to replace them with metal (for longevity). Is that wise? Or is choice of material, an important design consideration. (example: Is there sufficient power to turn new metal gears versus plastic?)
Here are a few terms I ran across in the parts catalogs: diametric pitch, pressure angle, face width, bore diam., pitch diameter, hub projection, hub diameter, outside diam, face width. I assume I need to measure these on my failed parts. How do you recommend I go about this? (i have already made a web search for gear parts nomenclature)
