Jaw crusher bearing - causes and solutions of excessive temperature.

Bearing is the most important part of the jaw crusher. It is easy to cause failure and damage the bearing under high temperature. The following is the reason and solution for the high temperature of the jaw crusher bearing explained by Huayang Jinggong.

1. The crusher bearing is worn or the cage is damaged, etc.: Check the wearing parts of the mechanical equipment in time and replace the worn bearings.

2. The axial movement of the adapter bushing: remove the bearing cover on the frame, lock the adapter bushing and remove the flywheel or groove wheel, and replace with a new adapter bushing.

3. The position of the counterweight of the flywheel of the crusher is out of alignment, and the frame jumps: the position of the counterweight of the flywheel is adjusted to ensure that the position is not offset.

4. Crusher bearing oil hole is clogged, oil can not be added: clean oil hole, oil groove blockage.

5. The crusher bearing has oil cut-off or too much oil injection: When the user is operating the equipment, please read the instructions carefully, and add oil on time according to the instructions.

6. Non-crusher bearing heating: friction heat generated by the movable jaw seal sleeve and the end cover or the double-embedded cover of the housing bearing seat rotates together with the main shaft to generate friction and heat. In this case, the end cover and sealing sleeve of the jaw crusher should be replaced, or the upper bearing cover of the hot end of the frame bearing seat should be loosened, and the fuse and the embedded cover should be pressed into the groove of the frame bearing seat, and then the upper bearing should be fixed. Cover to eliminate the rotation of the embedded cover.
