Vibrating screen with the main two kinds of vibration motor, vertical vibration motor is mainly used in the vibration sieve, the horizontal vibration motor can be applied to a variety of vibration screening equipment, and vibrating motor vibration is the most important vibration Source, its important position can be imagined. Vibration motor selection of heavy bearings, can carry a certain axial load, no matter how the installation direction, bearing life from axial load force.
1. Unload the bearing
(1) Remove the vibration shield at both ends of the motor (vertical vibration motor without protective cover), record eccentric work of the percentage of excitation force in order to restore the original installation work state;
(2) the axis of the shaft ends with a retaining ring removed;
(3) loosen the outer eccentric block fastening bolts, remove the eccentric block, a shaft key to remove the shaft keys. Loosen the eccentric block fastening bolts, remove the eccentric block;
(4) remove the bearing clamping bolts, with the appropriate bolts screwed into the bearing housing demolition screw, the bearing housings from the top out;
(5) Remove the bearing gland from the bearing housing, the bearing from the bearing out of the pressure or use the appropriate bolt out;
(6) If the bearing is a cylindrical roller bearing with separable inner and outer sleeves, the bearing inner sleeve shall be removed from the shaft and placed in the original bearing housing;
(7) thoroughly clean the oil components.
2. Install the bearing
Vibrating motor When replacing a new bearing, use the same bearing as the original one.
(1) bearing kerosene washed, pressed into the bearing, the outer ring of the bearing roller to fill the Shell III Lithium Grease to two-thirds full, evenly coated with a net hand, fitted bearing gland, with Tu Bolts, anti - loose plastic fastening bolts pressed bearing gland;
(2) bearings for the inner sleeve separable cylindrical roller bearings, bearings should be set on the shaft and in place;
(3) the bearing housing installed on the chassis, if the grease filling hole, must be aligned position. Tighten the bearing seat with the fastening bolts of the anti-loose rubber bolts;
(4) the eccentric block installed on the shaft and in place, a shaft key should be installed into the keyway key shaft and then install the eccentric block, the shaft with the retaining ring installed on the shaft;
(5) tighten the eccentric block fastening bolts, turning adjustable eccentric block, to reach the pre-removal angle and tighten the position of its fastening bolts. After completion of the above assembly, the shaft should have a certain axial string;
(6) on the vibration motor at both ends of the protective cover, fastened with screws.
