Document Type and Number:
Japanese Patent JPH04505728
Kind Code:
A
Abstract:
A rotary driven spindle (6) comprises sliders (14, 64) arranged on its front face, which can be adjusted radially as the spindle (6) rotates. To this end, an adjustment mechanism (21) comprises a device component (8) which rotates with the spindle and which can be moved relative to the spindle in order to adjust the slider (14). The radial centrifugal, frictional and working forces transmitted to the bearing housing (7) by the adjustment mechanism during adjustment of the slider (14) are compensated to a controllable extent by compensation of the centrifugal forces directly between the spindle and the device component (8). The compensation is effected by means of centrifugal weights (16, 66), the centrifugal force of which is deflected into axial forces. In one embodiment, the centrifugal weights (16, 66) penetrate a gap (12, 13) which tapers outward between two front faces (12, 13) of the component and the spindle. The centrifugal forces are converted to axial forces at the inclined surfaces (12, 13) which form the gap. The centrifugal force compensation is preferably arranged in the enclosed region between the bearings (17, 18) of the spindle (6).
