Thompson Coupling

A proof of concept model of a Thompson Coupling I made a little over a year ago for a CAD club. It is fully functional and mechanically identical to the real thing, and although it has intersection issues with its pantograph linkages and is missing a few pieces, it should give those interested a decent idea of how a Thompson Coupling works. Hope its useful! The Inventor file is 16.2 MB in size.. The stp file is 1.95 MB in size. The sat file is 4.66 MB in size. If you download the Inventor file, the thompson coupling is the file called 'Tapeworm CV Joint.iam' Also, if you are interested in CV joints, have a look at the Rzeppa coupling I made in SolidWorks: http://grabcad.com/library/adjustable-rzeppa-coupling -Alan Campbell
