Abstract
The invention relates to the assembly of a drive shaft with the cutting head hub of a submersible granulator. Said assembly comprises a connector hood which can be fixed to the drive shaft in such a way that it remains free to move. The connector hood is provided with threading for screwing the cutting head hub onto the drive shaft, said drive shaft being supported on a spherical extremity situated on the inside of the connector hood, and a cogged crown with inner-sided cogs is placed on the cutting head side of the drive shaft. The connector hood has inner-sided cogs which interlace with the cogs on the outer side of the cogged crown. The outer surface of each cog on the cogged crown is convex.
