A hydraulic clamp bushing formed for interconnecting a shaft and an object having a hub and being of the type comprising two expandable sleeves (1, 2) which are joined at least at one end thereof (3a, 3b) and which, in between said sleeves, define an all around extending recess forming a pressure medium recess which is filled with a hydraulic pressure medium (4), and which clamp bushing is formed with means (10) for internal or external pressurization of the pressure medium (4) in the pressure medium recess between said two expandable sleeves (1, 2), and in which the sleeves (1, 2) have a material width which, determined by the quotient between the outer diameter and the inner diameter of the respective sleeve, named kappa -value (kappa value), does not exceed 1.12 or is preferably between 1.09 and 1.11. The clamp bushing is made of such material that the bushing is not allowed to be subjected to a torque rotation of more thant 0.4 DEG -0.6 DEG at maximum torque transmission. The tolerance between the shaft and the inner sleeve (2), and also between the outer sleeve (1) and the hub, should be of the 6th to the 8th degree. |
