Abstract
A clutch device for tool holders or tool chucking or workpiece chucking devices is used for the releasable form-fitting engagement of a drive shaft, comprising a spindle of the tool holder or chucking devices, said spindle being coaxial with the drive shaft. The drive shaft and the spindle have separate dog elements, whereby, between the two dog elements, a clutch element is arranged that compensates for alignment errors between the drive shaft and the spindle and that can be moved in a limited manner between the drive shaft and the spindle. The clutch element is in form-fitting engagement with the dog elements of the drive shaft and of the spindle.

Clutch device for tool holders or for tool chucking devices or workpiece chucking devices for the releasable form-fitting engagement of a drive shaft (19) of an associate drive source (17) with a spindle (16) of the tool holder (12) or of the chucking device, wherein the drive shaft (19) and the spindle (16) support separate dog elements (24, 26a, 40), and wherein a clutch element (27) compensating for an alignment error between the drive shaft and the spindle is arranged between the two dog elements, whereby the movement of said clutch element is restricted with respect to the drive shaft and the spindle, and wherein said clutch element is provided with appropriate dog elements (24, 24a) and is coupled in a form-fitting manner with the dog elements of the drive shaft and of the spindle, said the dog elements comprising a keyway (24) extending transversely to the drive shaft (19) or to the spindle (16), or a strip-shaped dog (26;
- 26a) and said clutch element being held on one of the drive shaft or spindle by locking means (37, 38).
Clutch device for tool holders or for tool chucking devices or workpiece chucking devices for the releasable form-fitting engagement of a drive shaft (19) of an associate drive source (17) with a spindle (16) of the tool holder (12) or of the chucking device, wherein the drive shaft (19) and the spindle (16) support separate dog elements (24, 26a, 40), and wherein a clutch element (27) compensating for an alignment error between the drive shaft and the spindle is arranged between the two dog elements, whereby the movement of said clutch element is restricted with respect to the drive shaft and the spindle, and wherein said clutch element is coupled in a form-fitting manner with the dog elements of the drive shaft and of the spindle, characterized in that the dog elements comprise, as a first dog element, a keyway (24) extending transversely to the drive shaft (19) or to the spindle (16), or a strip-shaped dog element;
- and that the clutch element (27) has, on one face, a strip-shaped dog (26) coming into engagement with the keyway (24) with minimal play, or a keyway;
- and that the clutch element (27) has, on its other side, a second dog element (26a;
- 41) that is different from said first dog elements (24, 26) for the form-fitting engagement with a corresponding dog element (26a;
- 40) on the spindle (16) or on the drive shaft (19).
Clutch device for tool holders or for tool chucking devices or workpiece chucking devices for the releasable form-fitting engagement of a drive shaft (19) of an associate drive source (17) with a spindle (16) of the tool holder (12) or of the chucking device, wherein the drive shaft (19) and the spindle (16) support separate dog elements (24, 26a, 40), and wherein a clutch element (27) compensating for an alignment error between the drive shaft and the spindle is arranged between the two dog elements, whereby the movement of said clutch element is restricted with respect to the drive shaft and the spindle, and wherein said clutch element is coupled in a form-fitting manner with the dog elements of the drive shaft and of the spindle characterized in that the clutch element (27) is resiliently biased in axial direction with respect to the drive shaft (19) and/or the spindle (16).
Clutch device for tool holders or for tool chucking devices or workpiece chucking devices for the releasable form-fitting engagement of a drive shaft (19) of an associate drive source (17) with a spindle (16) of the tool holder (12) or of the chucking device, wherein the drive shaft (19) and the spindle (16) support separate dog elements (24, 26a, 40), and wherein a clutch element (27) compensating for an alignment error between the drive shaft and the spindle is arranged between the two dog elements, whereby the movement of said clutch element is restricted with respect to the drive shaft and the spindle, and wherein said clutch element is coupled in a form-fitting manner with the dog elements of the drive shaft and of the spindle characterized in that the tool holder (12) and/or the workpiece chucking device are set up for use in an appropriate receptacle (11) of a tool mount and/or workpiece mount (9), in which the respective drive shaft (19) is rotatably supported in fixed association with at least one receptacle (11).
Clutch device for tool holders or for tool chucking devices or workpiece chucking devices for the releasable form-fitting engagement of a drive shaft (19) of an associate drive source (17) with a spindle (16) of the tool holder (12) or of the chucking device, wherein the drive shaft (19) and the spindle (16) support separate dog elements (24, 26a, 40), and wherein a clutch element (27) compensating for an alignment error between the drive shaft and the spindle is arranged between the two dog elements, whereby the movement of said clutch element is restricted with respect to the drive shaft and the spindle, and wherein said clutch element is coupled in a form-fitting manner with the dog elements of the drive shaft and of the spindle characterized in that said clutch element has a longitudinal body which, on one face, is provided with a first dog element (26;
- 24) and on its opposite face, with a second dog element (24a, 41), and that its dog elements are set up for the form-fitting engagement with complementary dog elements on a spindle (16) of a tool mount (12) or of a chucking device or of a drive shaft (19) of a drive source (17).
