Jaw crusher wear phenomenon is inevitable in the daily operation, we only do regular maintenance service life can be extended to the utmost, so we in the jaw crusher Jaw crusher works for dynamic JiYaXing, its working principle is: motor drive belt and pulley, make through eccentric shaft dynamic jaw movement up and down, when moving jaw rises between the bracket and fixed jaw Angle, so as to promote dynamic jaw plate to the fixed jaw close, rather than the material being crushed or broken at the same time, achieve the purpose of broken;When the moving jaw downward, bracket and dynamic jaw Angle smaller, moving jaw in the bar, under the action of the spring, leave the fixed jaw plate, now broken material from crushing cavity mouth eduction.As the motor turns continuously and broken mobile jaw crushing and discharge material for periodic motion, to realize batch production of mandrel, eccentric shaft and bearing bush of long-term maintenance!
Axis wear if very few, just to repair its geometry, turning on a lathe, make the journal reach the correct geometry, and the decrease of the corresponding bearing inside diameter.But after a few such processing, if the shaft neck size is reduced to 5%, were not allowed to turning again, and should be replaced a new shaft.
Jaw crusher is working under impact load, bearing on babbitt lining, deadlines for about 2 years or so, over time, you need to cast.If the eccentric shaft and bearing, spindle and bearing is wear, the tip clearance is greater than 1.5 times of the original assembly clearance, need to add cushion adjustment or replacement;Oil groove wear of 1.5 mm, should restart oil groove and adjustment.Connecting rod head cover and the space between the eccentric shaft, wear to greater than 1.5 times of assembly clearance, also need a padded adjust or replace new one.When the babbitt on the bearing shell has deep peeling or abrasions, shall be cast again.For processing after the quality of the bearing has the following requirements: babbit more uniform, no light, the color of the surface of the silver;Babbitt metal surface layer should not have ash, crack, sand holes, shrinkage cavity and shell, etc.
