AN ARRANGEMENT FOR ADJUSTING ROTOR POSITION IN A ROTING SLUICE
The invention concerns an arrangement for the adjustment for wear of the position of the rotor of a sluice feeder within the casing. The rotor has the form of a truncated cone and the play between the rotor and the surrounding casing is adjusted depending on the wear between the rotor and the casing through the rotor being axially displaced a predetermined displacement. According to the invention, the complete driving unit, motor 60 and gear box 61, is suspended on the journal of the rotor 7, and where the driving unit receives support from a torque support in the form of a beam 70a, 70b fixed in the casing. The complete driving unit accompanies the rotor shaft during adjustment and makes contact with the torque-absorbing beam 70a, 70b through sliding bearing supports 73a, 73b, 72a, 72b. Initiation of the adjustment takes place in an adaptive manner, depending on a parameter, driving torque or leakage flow, that is indicative of the current degree of wear between the rotor and the casing, and the adjustment is initiated when a threshold value of the parameter is passed.
