Can a Swash Plate Mechanism be Adapted for Radial Displacement Along a Spoke?

[QUOTE="Trakyan, post: 5441337, member: 590777"] This is a hard one to describe and I couldn't think of a better tittle, sorry. My aim has been for a while to create a mechanism which allows me to move an object (i.e a washer or something) in or out radially along a spoke of a wheel. However I have some restrictions which have made me scrap my designs so far (most of them involved very complicated mechanisms with lots of moving parts) so I've decided to look for some help. The mechanism needs to be able to be controlled from off of the axle (it can't be rotating with the spokes, that creates an issue of how you access or actuate the mechanism itself when its spinning with the axle). See the video below for an example. [MEDIA=youtube]yweIWBC9-OA[/MEDIA] The design in the video uses a disc with spiral groves which is rotated relative to the axle and that forces the bolts to slide radially outwards. This presents the issue of how do you isolate the movement of the spiral disc from the rotation of the axle? I've seen designs like this http://i.kinja-img.com/gawker-media/image/upload/gv95ipcvuvvgpxoi8pm2.jpg which use a scissor jack like design. The issue this presents though is that the device takes up a lot of space width wise. The washer/object that slides along the spoke must be able to be held in place by the mechanism to stop it from sliding up or down the spoke to a new position. Anyone have any ideas? Thanks [/QUOTE]
