Rotary to Reciprocal motion 5

[heidt]

Does anyone know a mechanical way to convert rotary motion to reciprocal motion withen a confined space?

Ok, I'm not sure whether my suggestion has a name for it or whether it's mentioned. My suggestion is to use a long threaded rod with the pitch travel you wanted per revolution. Add a coupling at one end so that a motor can be attached directly or through a step down. Next, put a piece of metal with a threaded hole that mates with the rod. Restrict the rotation movement of the metal piece but not linearly.

How about a Geneva machanism? they are simple to make and will do the job. I recently saw one on an automatic pancake making machine. It was great!

Isn't a Geneva mechanism more for indexing

It's taken me some time, but I finally found the device I wanted to suggest. These can be very large mechanisms but nowhere did see your load requirements, so you can scale them down some.

Just another thought
