<p>The invention relates to a food processor comprising a housing 1, a bowl 3, a cover 4 having a feeding tube 5, a driving shaft 6 which is driven by a motor via a transmission mechanism 7, the said driving shaft being formed by an upper shaft 11 and a lower shaft 12 which are connected together by means of a coupling 19, the upper shaft 11 being journalled in the cover 4 and being suitable for connecting a tool thereto, the lower shaft 12 being journalled in a frame plate 15 by means of a bearing 17, said frame plate being suspended in the housing. The value of the tolerance of clearance S depends on a large number of other tolerance-dependent dimensions. In known food processors the axial forces are compensated by the bearing 17. According to the invention the driving shaft 6 is journalled axially in the housing 1 (bearing 25). As a result of this the tolerance path for the clearance S has become much smaller. It is also possible to journal the upper driving shaft 11 axially in the bowl 3.</p> |
