Vibrating screen with the vibration of the main motor and two, horizontal vibration motor can be used in a variety of vibration screening equipment, and vibration motor is the main vibrating screen vibrating belt seat spherical source, regardless of how the installation direction Type vibration motor main mill to be applied in the rotary sieve, its important position can be imagined. Vibration motor selection of heavy-duty bearings, can carry a certain axial load, bearing bearing the furnace bearing life is not affected by the axial load force.

 

Bearing with kerosene wash, with a clean hand smear evenly, press into the seat, bearing the outer ring needle roller bearings filled with three lithium-based grease to two-thirds full, fitted with bearing gland, with anti-bolt Pneumatic tightening of the one-way bearing bolts.

 

Bearings for the inner jacket can be separated from the cylindrical roller bearings, the bearing should be set in the self-aligning ball bearing shaft and in place.

 

When the vibrating motor is replaced with the new shaft INA, it must be used in the same way as the original model.

 

Inside and outside the eccentric block mounted on the shaft and in place, the shaft key should be full of roller bearing key into the keyway and then install the outer eccentric block, the shaft with a ring on the shaft.

 

Install the bearing

 

On the vibration of the motor at both ends of the protective cover, fastened with screws.

 

Will seat on the chassis, if the grease filling hole, must be aligned position. Tighten the bearing with the tightening bolts with the screw threads.

 

Tighten the eccentric block fastening bolts to the front angular position and tighten the fastening bolts. After the completion of the above assembly, turn the Chinese network adjustable eccentric block, the shaft should have a certain axial bearing seat chord.

 

Remove the shaft with two shaft ends.

 

Tapered roller bearings Remove the gland from the seat, press out from the seat or use the appropriate other angular contact ball bearing bolts.

 

Unloading

 

Remove the seat compression bolts, screw the seat with the appropriate bolts to remove the screw holes, and lift the housing from the housing.

 

Spin loose outer eccentric block fastening screw linear movement bolt, shaft key to remove the shaft key. Loosen the inner eccentric block fastening bolts, remove the outer eccentric block, remove the inner eccentric block.

 

Thoroughly clean the parts oil.

 

Remove the protective joint at both ends of the vibration joint motor (vertical vibration motor without a protective cover), record the eccentric block work when the special joint bearing excitation force percentage, in order to restore the original state of the SKF bearings installed.

 

Such as the shaft straight for the inner jacket can be separated from the full complement cylindrical roller bearings cylindrical roller, the sleeve should be removed from the shaft, and into the original bearing jacket.
