What should I do if the temperature of the jaw crusher bearing is too high?

Jaw crusher has the characteristics of large crushing ratio, uniform product size, simple structure, reliable operation, easy maintenance and economical operation cost. Jaw crushers are widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries and many other sectors, crushing various materials with a compressive strength not exceeding 320 MPa. The jaw crusher shaft bears the full load of the entire machine operation 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 in normal operation. The common fault of jaw crusher bearing is that the temperature is too high.

一、The bearing of the jaw crusher is cut off or injected with too much oil.

Simple solution: Just check the manual carefully, and fill in oil regularly and quantitatively according to the regulations.

二、Block the oil hole and add oil.

Simple solution: shut down the machine to clear the blockage inside the oil hole and oil tank.

三、The position of the flywheel counterweight deviates, and the frame jumps;

Simple solution: adjust the position of the flywheel counterweight to stabilize the frame.

四、The axial movement of the fixed bushing occurs;

Simple solution: remove the bearing cover on the frame, lock the fixed bushing and remove the flywheel or sheave, or replace the new fixed bushing, in short, to ensure the stability of the fixed bushing.

五、Bearing wear or cage damage;

Simple solution: repair or replace new bearings and cages.

六、Non-bearing reasons, friction and heat between the movable jaw seal sleeve and the end cover, or the double-embedded cover of the frame bearing seat and the main shaft rotate together, causing friction and heat, resulting in an increase in temperature.

Simple solution: replace the end cover and sealing sleeve, or loosen the upper bearing cover on the hot end of the bearing seat of the frame, press the fuse and the embedded cover into the groove of the bearing seat of the frame, and then fix the bearing cover and remove the embedded cover turn.
