Patent ID: 8061924

Claim:
Clamp system for connecting a motor shaft to a transmission, the clamp system comprising a hub ( 3 ) and at least one fixing element ( 7 ) inserted tangentially in a clamping element (R 1 , R 2 ), wherein: the clamping element (R 1 , R 2 ) forms an elastically deformable region over one of at least one hole ( 12 ) or at least one recess ( 13 ); the deformable region is arranged approximately opposite a gap ( 8 ) of the clamping element (R 1 , R 2 ); one of the at least one hole ( 12 ) and/or one recess ( 13 ) forms a mass balance for an unbalanced mass arising because of the gap ( 8 ) and the fixing element ( 7 ); the fixing element ( 7 ) extends tangentially through the clamping element (R 1 , R 2 ) and at least slightly radially protrudes out of an inner circumferential surface ( 18 ) of the clamping element; at least one hole ( 12 ) or recess ( 13 ) is provided opposite the gap ( 8 ); the hole or recess is used for the mass balance and simultaneous formation of an elastically deformable region in order to elastically deform the clamping element (R 1 , R 2 ) in a tangential direction by means of the fixing element ( 7 ); and the system further comprises at least one weight ( 15 ; 15 ′) in one of the at least one hole ( 12 ) and at least one recess ( 13 ) to balance an unbalanced mass so as to provide mass balance.
