Abstract
A method and apparatus are disclosed for joining a drive band to the driven element of a servo-controlled precision motion system. A vibration dampening clamp assembly absorbs unwanted vibration energy. The clamp assembly utilizes energy absorbing molded grommets which mechanically isolate the driven element from the band. A threaded fastener passing through an axial bore in each of two energy absorbing grommets is used to join two halves of a clamp assembly. The grommets are preloaded at assembly using threaded fastener and a nut to compress each grommet to a known compression prior to tensioning of the drive band. Upon final tensioning of the band drive assembly, the grommets are brought to a final compression value.
