ABSTRACT:
Tooling for applying an abrasive belt on a machine for abrasive belt machining of cylindrical bearing surfaces comprises, for each bearing surface to be machined, an arm and three abrasive belt application shoes a first of which is mounted in a top median position on the arm and the other two of which are mounted in a bottom lateral position on two jaws articulated to the arm and coupled together in such manner that they can be clamped together. The arm carries a first shoe having a concave abrasive belt application surface subtending an angle greater than 90.degree. and less than 180.degree. and a gauge with two opposed and horizontally aligned sensors and each jaw carries a second shoe having a concave abrasive belt application surface subtending an angle slightly less than 90.degree. whereby when clamped around the bearing surface to be machined the three shoes together envelope the bearing surface to be machined over an angle of at least 270.degree., the first above and the second two below the two sensors of the gauge which are disposed on a common diameter of the bearing surface. The tooling has applications in abrasive belt machining of journals and crankpins of crankshafts.
