<p>A receiving plate (22) with a vertical axis of rotation (24) for a grinding bowl (91) is mounted on a housing (10,20) through a thrust bearing (26) and a radial bearing (28) which take up grinding forces acting on the bowl (91) in operation. The receiving plate (22) is additionally connected to the housing (10,20) by a counter-pressure bearing which prevents the plate from being lifted from the housing. The receiving plate is driven through an epicyclic gear (50) which is coaxial therewith and which comprises a satellite carrier (62) secured to the receiving plate (22) and an outer central wheel (64) which is secured to the lower housing portion (10) and which carries the thrust bearing (26). The counter-pressure bearing (27) is formed from a shoulder (87) formed on the satellite carrier (62) and a collar (89) formed on the outer central wheel (64) and which engages over the shoulder (87). <IMAGE></p> |
