*1. The bearing of the jaw crusher is broken or too much oil is injected.
Simple solution: Just check the instruction manual carefully and fill oil regularly and regularly according to regulations.
Second, block the oil hole and cannot add oil.
Simple treatment method: Turn off the machine and clean the oil holes and oil tanks to block the internal blockages.
Third, the counterweight of the fly trough wheel is off-limited and the frame jumps;
Simple treatment method: adjust the position of the counterweight block of the forward fly tank wheel and stabilize the frame.
Fourth, the tightening bushing will cause axial movement;
Simple solutions: remove the bearing cover on the frame, lock the fixing bushing and remove the flywheel or groove wheel, or replace the new fixing bushing to ensure the stability of the fixing bushing.
Fifth, bearing wear or cage damage;
Simple solution: Repair or replace new bearings and cages.
Sixth, non-bearing reasons, the moving jaw sealing sleeve and the end cover are frictionally heated, or the double inlay cover of the frame bearing seat rotates together with the spindle, frictionally heats up, resulting in an increase in temperature.
Simple treatment method: replace the end cover and sealing sleeve, or loosen the upper bearing cover at one end of the frame bearing seat, press the fuse and the inlay cover into the frame bearing seat groove, and then fix the upper bearing cover to eliminate the rotation of the inlay cover.
All JC series jaw crushers are equipped with larger and more durable eccentric bearings than other crushers of the same specifications. The higher load-bearing capacity and effective labyrinth seal greatly extend the service life of the bearing.
What to do if the temperature of the jaw breaking accessories is too high when operating
The jaw crusher has the characteristics of large crushing ratio, uniform product particle size, simple structure, reliable work, simple maintenance, and economical operation costs. Jaw crushers are widely used in many departments such as mining, smelting, building materials, highways, railways, water conservancy and chemical industries, crushing various materials with a compressive strength of no more than 320 MPa. The jaw crusher bears all the load for the operation of the entire machine and plays a decisive role in whether the machine can work normally. Therefore, during the working process of the jaw crusher, it is necessary to pay attention to whether the bearing is operating normally. The most common fault of jaw crusher bearings is that the temperature is too high. What should I do if the temperature of the jaw crusher bearing is too high when it is running.
