PCT No. PCT/AT93/00076 Sec. 371 Date Jan. 3, 1995 Sec. 102(e) Date Jan. 3, 1995 PCT Filed May 3, 1993 PCT Pub. No. WO93/22584 PCT Pub. Date Nov. 11, 1994A drive unit having a drive gear rotatable about a drive-gear axis mounted on an angle transmission having a housing formed unitarily of one piece with a throughgoing passage centered on a longitudinal axis, a plurality of substantially planar outer faces each extending substantially parallel to the axis, one of the outer faces bearing flatly on the drive unit, a transverse bore opening at and extending between the one face and the passage along an axis transverse to the longitudinal axis, and a plurality of undercut grooves extending longitudinally the full length of the housing and opening at least at the one outer surface. Each of the grooves is substantially narrower at the respective outer face than inward therefrom measured in a direction transverse to itself and parallel to the respective outer face. A main gear is rotatable in the passage about the longitudinal axis and a drive gear is rotatable about the transverse axis in the transverse bore in mesh with the main gear. A plurality of bolts seated in the drive unit each have an enlarged end in a respective one of the grooves of the one face so that the bolts clamp the drive unit and housing together parallel to the transverse axis. |
