Abstract:
PCT No. PCT/SE96/00076 Sec. 371 Date Jul. 24, 1997 Sec. 102(e) Date Jul. 24, 1997 PCT Filed Jan. 25, 1996 PCT Pub. No. WO96/23982 PCT Pub. Date Aug. 8, 1996Hydraulic clamp bushing (13, 14) having a double walled sleeve (7), a hydraulic pressure medium which is trapped in a chamber (5) between the sleeve walls, and a mechanism for pressurizing the pressure medium. One, or both, sleeve walls (7) is/are formed for expanding radially outwards and/or inwards when the pressure medium is pressurized, whereby the clamp bushing is clamped to a shaft, a hub or a similar object, in particular a rotary shaft (17, 18). The pressure medium chamber (5) is formed with angularly inwards or sigma formed bushing ends (9) designed so that the ends are straightened up as a first stage when the clamp bushing is pressurized, whereby the axial ends of the bushing facing the shaft (17, 18) are pressed to the shaft (17,18) thereby providing a straightening up of the bushing (13, 14) on the shaft before the intermediate portions of the sleeve are pressed to the shaft (17, 18).
