Considering a Gear as a roller

  1. Feb 15, 2010 #1
    Hi Guys,

    I have been scouring books and the internet for a while as well as my university notes but I really cant find any information on why a roller can be used as a replacement for a gear. The situation is that I have to design a test rig to simulate two gears running together to investigate micropitting. All the journals I have read use rollers, but they don't justify why they are using rollers.

    I understand that kinematically a roller is identical to a gear, however there are a few things where to me they just don't match up. For example the slide:roll ratio. So the question I am really asking is how are they similar and are there any sources that can prove this?

    Sorry if this is in the wrong section, I did see the warning "Do NOT post homework", this is not homework although I can see why it would be considered as such (Its research I am doing for my "project ie dissertation).

    I would appreciate any help possible.

    Thank you
