Abstract
A fixture for mounting a rotor having a cylindrical bore on a cylindrical shaft having a first section adapted to be clamped within the bore of the rotor by expansion of its outer periphery, and a second section adapted to be clamped onto the shaft by contraction of its central bore. The second section has complementary partial-circular segments. A fastener is mounted on one side of the shaft to cause the segments on one side of the shaft to close and grip the shaft. Further tightening of the fastener effects separation of the segments on another side of the shaft. The first section has two partial-circular segments joined with the two segments of the second section, so that when the segments of the second section are separated, the segments of the first section is likewise separated to clamp the first section within the bore of the rotor. There may be two, three or four sections allowing one or two first sections to clamp against the inside bore of the rotor and the other second sections to clamp against the shaft. The two segments of each section may be formed integrally or separated, and may include keyways to avoid gulling on the shaft and rotor.
