Tool fixture for overhung tools, e.g. roller, screw and rotor in compacting and granulating machine, involves each tool having drive dog and recess towards tool rotation whereas recess has larger extension than cavity

摘要

Tool fixture involves tool (4,8,8') or its drive shaft (7,7',7'') having a drive dog (9,9',9'') or running transversely to the assembly direction of the tool, recess (11,11',11'') to take up the drive in installed condition of the tool. The recess with a front surface (18) of the free end of the drive shaft or the drive side seated to the outer contour (13, 13') of the tool is connected over a cavity (12,12',12''). The recess in direction of rotation (14,19) of the tool has a larger expansion than the cavity.
