Abstract (en)
[origin: EP0617170A2] The mobile apparatus has a motor-driven rotor drum which is accommodated in a housing. The drum consists of a rotor shaft (5) on which there is fixed a hollow shaft (20) with a fixed terminal flange (21). Diamond cut-off discs (23) and spacer rings (24) are arranged in a row in alternate sequence on the hollow shaft (20). At least two holding bars (22) running parallel to the hollow shaft (20) pass through the diamond cut-off discs (23) and the spacer rings (24) and are mounted in a counter-flange (25) which is held on the hollow shaft (20) so as to be secure (26) against rotation. The diamond cut-off discs are thus mounted on the hollow shaft (20) in a manner held together positively and non-positively to form an assembly. As a result, a steady mounting of the diamond cut-off discs is obtained and a great cutting depth of the apparatus is achieved. <IMAGE>
