Here is even an calculator to do it for you. http://www.botlanta.org/converters/d.../sprocket.html
As for if this drive needs a suspension or not totally depends on your team and it's engineering decisions regarding the application for this drive. Keep thinking outside of the box it will serve you well in the future.
There are no absolutes in engineering decisions. People and organizations value different things and out of context it would be wrong to make assumptions on the necessity of a feature. |
Thank you very much for your feedback!
The goal was to show how I intend to keep the chain under tension while it is pivoting. The nylon spacers are adjustable so that they can act as chain tensioners. When the carriage moves up and down, the tensioners will as well, theoretically keeping the chain under tension. If any one knows whether or not this will work, please let me know.
The bushing question was in reference to the bushings on the carriage that are currently brass. I guess a better way to phrase it would be to ask whether brass or nylon has a lower coefficient of friction with aluminum.
