All the hanging bearings of screw conveyor should be hanging on the connecting shaft reliably without stuck and bending of screw. When installation, adjusting the gaskets number of hanging bearing to make no gap in subdivision surface while a proper radial gap between bearings and connecting shaft.
Hanging bearing should be installed in the center of connecting shaft, the distance between end face and two screw pipes should be over 10mm when D≦400mm and over 20mm when D≧500mm.
To adjust the accumulative error between chassis and screw, there should be padding asbestos lining between the flange of the chassis when installation. Padding waterproof canvas between chassis and cover according to the requirements for sealing.
When the difference of center heights of driving gear reducer shaft at low speed and screw conveyor is too much, using the gaskets to adjust the height of driving unit.
When no-loading running, if there is oil leakage phenomenon, removing the bearing and adjusting the tightness of spring in sealing ring until no leakage.
When no-loading running, overheating of hanging bearing indicates the installation position of hanging bearing is improper which leads the locking of connecting shaft, there should be loosing the fasten bolt and adjusting the position of hanging bearing.
