  • Hammer-crusher rotor
    Patent number: 4973005
    Abstract: A drive shaft (2) rigidly carries disks (4) through which parallel and eccentric hammer carrier axles (6) pass. Between the disks (4), hammers (7) are mounted pivotably about the hammer carrier axles (6). Protective covers (8) cover the disks (4) and the inter-disk spaces not occupied by hammers. Each cover (8) has the form of a sector of cylinder terminating in rims (11, 12) facing the drive shaft (2) and engaged in notches (13) of the disk. On a disk (4) two consecutive notches (13) between them define a dovetailed boss and form a retaining and guiding shaped portion avoiding the use of screw fastenings and serving as a slideway during assembly.
