- the solution according to the invention is therefore particularly suitable for machines with high output, such as, in particular, for network machines.
- the drive shaft can in principle be formed by a motor shaft, an output shaft of a gear, in particular an angular gear, or by a shaft adjoining an output shaft of a gear in the direction of the tool.
- the form-locking element can be formed by an integrally formed groove in which an additional, for example tooth-like, transmission means can be fastened, as a result of which, with regard to its material properties, it can be specifically oriented to the existing loads, or the form-locking element can advantageously be used directly for contacting the means of Driving device or the driving flange can be used, whereby additional components, assembly effort and costs can be saved.
- the form-locking element is molded onto the drive shaft by a pressing process, this can advantageously be implemented cost-effectively with narrow tolerances.

- the positive-locking element have a greater length extension in the axial direction of the drive shaft than height, which means that, in particular, space-saving transmission surfaces and associated small surface pressures and wear can be achieved.
- the drive shaft has at least three form-fitting elements, an advantageously uniform distribution of forces can be achieved with an overall large transmission surface.
- only one or two form-locking elements are also conceivable.
- the means of the entraining device have at least one continuous axial groove forming a form-locking element on its inner circumference, as a result of which particularly inexpensive manufacture of the means can be achieved, in particular if it is formed by a sintered part.
- the means of the driving device is formed by a driving flange which forms a contact surface for the insert tool, additional components, installation space, installation effort and costs can be saved.
- the means of the driving device is supported on the drive shaft via a spacer element. Transitions between the form-locking element and adjacent areas caused by a manufacturing process can advantageously be bridged by means of the spacer element and cost-intensive contours on the means of the driving device corresponding to the transitions can be avoided. It is
- Spacer element advantageously formed by a sleeve that is easy to assemble and by means of which it is easy to implement a uniform support.
- the tool holding device comprises a leaf spring unit which has at least one free spring web extending at least partially in the circumferential direction, as a result of which a space-saving leaf spring unit with an easily produced contour and with an advantageous power transmission can be achieved inexpensively.

- the driving flange 10 When mounting the driving device 12, the driving flange 10, a leaf spring unit 58 and the sheet metal plate 48 are preassembled.
- the leaf spring unit 58 is pushed onto a collar of the driving flange 10, which points in the direction facing away from the insert tool 14.
- the tensioning hooks 56 of the sheet metal plate 48 which have a hook-shaped extension with an inclined surface 94 pointing in the circumferential direction 52 at their free end, are then guided in the axial direction 54 through recesses 60 of the driving flange 10 (FIGS. 2 and 3).
- the leaf spring unit 58 is biased and the plate 48 and the driving flange 10 are positively connected in the axial direction 54, 64 (Fig. 2 and 3).
- the sheet metal plate 48 is then, loaded by the leaf spring unit 58, on the contact surface 30 of the driving flange 10 supported over edges of the hook-shaped extensions which point axially in the direction facing away from the insert tool 14.
- the leaf spring unit 58 has three identical, free spring webs 110 which extend in the circumferential direction 50, 52 and which are each made in one piece with a retaining ring 114 via a radially inwardly extending connecting web 112 (FIG. 4).
- the connecting web 112 and the spring web 110 are essentially T-shaped, the spring web 110 being arched with two free ends and the connecting web 112 connecting to the spring web 110 in the middle thereof.
- the spring bar 110 has a decreasing width 120 toward its free ends 116, 118 and has a thickness 126 of approximately 0.9 mm.
- the leaf spring unit 58 rests with its retaining ring 114 on the driving flange 10, the spring webs 110 each being bent from the connecting web 112 in the direction of their free ends 116, 118 in the direction facing away from the driving flange 10 and supported on the tabs 68 of the sheet metal plate 48 are.

- coding means 128 are formed on the outer circumference of the retaining ring 114 in addition to the connecting webs 112 which extend radially outward and correspond to the tensioning hooks 56 and bolts 20 of the driving device 12 during assembly.
- the sheet metal plate 48 can be guided in a twisted position with its tensioning hook 56 through recesses in the leaf spring unit 58, but then a driving plate 96 with its bolts 20 can no longer be guided through the leaf spring unit 58 due to the coding means 128.
- the preassembled assembly consisting of the sheet metal plate 48, the leaf spring unit 58 and the driving flange 10, is then mounted on the drive shaft 16.
- the bolts 20 are guided through tabs 68 formed on the circumference of the sheet metal plate 48, which have bores 70, and through through bores 72 located in the driving flange 10 and engage in the assembled state through the through bores 72.
- the form-locking elements 100 on the drive shaft 16 are inserted into the form-fitting elements 106 of the driving flange 10.

- the sheet metal hub 42 of the insert tool 14 has three shaped elements 24 which are distributed in the circumferential direction 50, 52 evenly over the circumference of the centering bore 46 (FIG. 2).
- the shaped elements 24 are formed by recesses.
- the shaped elements 22 of the tool holding device and the shaped elements 24 of the insert tool 14 are coordinated, corresponding shaped elements to simplify assembly of the insert tool 14. Furthermore, the corresponding shaped elements 22, 24 form a coding means for avoiding the assembly of an impermissible insert tool Same type. For this purpose, the corresponding shaped elements 22, 24 are coordinated with one another with regard to a diameter of the insert tool 14, so that insert tools for use in machines at high speed have a wide shaped element or a wide coding and insert tools for use in machines with low speed a narrow form element or a narrow coding.

The insert tool 14 comes to rest on contact surfaces 84 of the shaped elements 22. Twisting the insert tool 14 in the circumferential direction 50, 52 brings the shaped elements 22, 24 to congruence.
- Insert tool 14 or the sheet metal hub 42 can then slide in the axial direction 64 in the direction of the contact surface 30, and the sheet metal hub 42 comes to rest on the bolt 20.
- a subsequent pressing of the sheet metal hub 42 against the contact surface 30 of the driving flange 10 causes the bolts 20 in the through bores 72 and the driving disk 96 to be axially displaced against the spring force of the spring element 18 on the drive shaft 16 in the direction 64 facing away from the insert tool 14 ,
- radially outwardly directed formations 86 of the drive plate 96 engage in Talking locking pockets 88 of a bearing flange 90 which is fixedly connected to the gear housing 38 and lock the drive shaft 16.
- the sheet metal hub 42 can be rotated counter to a drive direction 98.
- the rotation of the sheet metal hub 42 causes the sheet metal hub 42 to slide with its edge of the centering bore 46 into the distance 28 between the shaped elements 22 and the contact surface 30 of the driving flange 10 and can be secured against falling off in the axial direction by the shaped elements 22.
- the rotation of the sheet metal hub 42 causes the hook-shaped extensions to be moved into the arcuate, narrow areas 80 of the recesses 78 of the sheet metal hub 42.
- the sheet metal plate 48 with the tensioning hook 56 is axially displaced in the direction 54 against the pressure of the leaf spring unit 58 by inclined surfaces, not shown, until bearing surfaces of the hook-shaped extensions in the arcuate, narrow areas 80 borrowed next to the recesses 78 of the sheet metal hub 42 for contact come.
- arc-shaped grooves 66 are introduced into the contact surface 30 of the driving flange 10, via which undesired particles lying on the contact surface 30 can be conveyed outward from the driving device 12.
- the pressure of the spring element 18 causes the drive plate 96 to slide upward.
- the bolts 20 snap into the cup-shaped recesses 76 of the sheet metal hub 42 and secure them in a form-fitting manner in the circumferential direction 50, 52.
- the formations 86 of the drive plate 96 disengage from the locking pockets 88 of the bearing flange 90 and release the drive shaft 16.
- an unlocking button 92 is pressed in the axial direction 64.
- the release button 92 presses the drive plate 96 in the axial direction 64, and the formations 86 of the drive plate 96 come into engagement with the locking pockets 88.
- the drive shaft 16 is locked.
- the bolts 20 disengage from the recesses 76 in the sheet metal hub 42, and the sheet metal hub 42 can be rotated in the circumferential direction 52 until the tensioning hooks 56 can slide through the recesses 78.
- the shaped elements 22, 24 come into a corresponding position, and the sheet metal hub 42 can be removed in the axial direction 54.
