Definitions

  • the stirrer usually consists of a stirrer shaft with stirring tools arranged inside the grinding chamber. Outside the grinding chamber, a drive is arranged, the drive power is transmitted via a drive shaft to the stirring shaft.
  • the drive shaft is performed dynamically in an end wall delimiting the grinding container, wherein the passage comprises a so-called dynamic seal for sealing the rotating shaft relative to the end wall.
  • the stirring shaft is fixed to the drive shaft in such a way that the rotational movement of the drive shaft is transmitted directly to the stirring shaft.
  • the drive shaft 40 is in particular designed as a hollow shaft and has along its longitudinal axis X40 a continuous cavity 44.
  • the drive-near end portion 55 of the fully stocked stirrer shaft 51 is inserted into the receptacle 62 of the drive shaft 60. Between the drive-near end portion 55 of the agitator shaft 51 and the receptacle 62 of the drive shaft 60 a small clearance is formed.
  • the spring element 58 that is disposed within the receptacle 62 between the drive-near end portion 55 of the stirring shaft 51 and the drive shaft 60, an operative connection between the stirring shaft 51 and the drive shaft 60 is made, so that the torque of the drive shaft 60 transmitted to the stirring shaft 51 can be.
  • the shaft flange 80 is movably disposed on the second end portion 65.
  • the second end region 65 has a shaft collar 66 and / or a circumferential groove 69 is formed at the second end region 65.
  • the shaft flange 80 is preferably rotatably formed to the drive shaft 60 and or at least partially axially movable relative to the longitudinal axis X60 of the drive shaft 60.
  • the shaft flange 80 is formed such that it is partially mounted on the shaft collar 66 of the drive shaft and partially engages in the circumferential groove 69, wherein the engaging in the circumferential groove 69 has a portion which is less than the width of the Circumferential groove 69.
  • the first shaft flange 130 on the second end region 115 of the drive shaft 110 designed as a shaft collar 116 thus serves as a clamping device in conjunction with a contact surface of the shaft flange 130 and at least one screw 140.
  • the tie rod 120 bears against the abutment surface A of the shaft flange 130.
  • the tie rod 120 is clamped in that the shaft flange 130 by tightening the screws 140 bears against the shaft collar 116, that is, the shaft collar 116 is clamped between the Switzerlandankerflansch 125 and the shaft flange 130 and thus an operative connection between the tie rod 120 and the drive shaft 110th produced.
