Clamping device with a centering device on a grinding spindle rotor and rotor with such a centering device.

摘要

Clamping device with a on a grinding spindle rotor recorded rotor (1),with a on the grinding spindle rotor centering portion is formed, which penetrates an inner recess of the rotation part of this in a centered manner,with a mutual centering contact between the inside recess of the rotation part and the centering portion of the grinding spindle rotor by means of three support structure, which are arranged in the angular distance from one another,and with a detachable device for the axial clamping of the rotation part on the grinding spindle rotor,characterized in thattwo of the three support structure as solid projections (11) of the rotation part (1) are formed which in the internal recess (10) project,and in that the third support structure a in the rotor (1) is movably mounted adjusting member, which is located between a radially outwardly, retracted, position, or a radially inwardly, extended, centering position is movable,with its centered position in relation to the centering portion (4) on the centering portion (4) is in contact with.
