Abstract

The elastomer liaison piece (pref. of polyurethane) acts as an alignment compensator, and is for use in mounting a tool, e.g. a thread cutting bit on the spindle of a machine tool. The use of elastomer is economic, provides greater elasticity and obviates abrupt failure. The compensator may be traversed by a longitudinal axial hole and may have a double truncated come external form. The two truncated cone forms are joined by their large base at the mid-point in the length of the piece and the piece is symmetrical relative to the median transverse cross-section. A transverse hole at each longitudinal extremity provides for attachment to the tool and the spindle resp. by cotter pinning, etc.
