A locking screw (8) and a distance bush (9) act as retaining elements.
A spacer bush (62) is arranged axially between said inserts in which sleeve the piston collar (71) is moved and fluidically separates the two annular spaces (72, 73) arranged laterally of it.
The aim of the invention is to provide a means for forming a screw connection as easily as possible using a distance sleeve (4).
The securing head takes the form of a coronal hollow end region of the spacing sleeve.
An extension of the expanding sleeve extends backwards over the area of the crank.
The ferrule design of the invention provides ridged piece to piece joining, eliminating pinching and hinging points.
A spacer sleeve (15) is to be arranged between said second end (10b) of the needle ring (10) and the side wall (5) which faces it.
According to the invention, the expanding sleeve contacts the tie rod with a friction fit without threads, said tie rod being preferably cranked.
The other end of the crankshaft (1) is connected to a rotor (11) of the servo motor (4) by means of an expanding sleeve (10).
To create a locking element (17) for transportation, the distance bush (9) is provided with at least one projection (18), directed radially inwards, said projection radially overlapping a section of thread (20) of the locking screw (8).
The sleeve can be connected to the respective connection pipe (6) for example by means of a screw plate (10) and an annular seal (5) is fixed by means of a spacer sleeve (3) that can be likewise shortened.
For adjustment purposes, and particularly for the precision adjustment of the distance (a) between the cutters (3, 4), a spacer sleeve (6) is provided, which is displaceable in the axial direction (A) of the tool holder (2).
