The overall performance of the jaw crusher is closely related to the size of the machining of each part. In the machining process of the crusher, it is required to ensure that the tolerances of the drawings are guaranteed as much as possible so as to reduce the accumulated error of the machining and to make the assembly quality better improve. The following Pang Bo Heavy Industries to introduce you to jaw crusher bearing assembly should pay attention to the four major points:
 

1.Strict control of the heating process

Because the bearing in the assembly process needs to use the principle of thermal expansion and contraction to achieve interference fit, so the heating process must be strictly controlled for different specifications, the size of the bearings to choose the appropriate temperature for heating. Jaw crusher bearing diameter Φ650, diameter Φ400, are large bearings, heating process is often uneven heating, resulting in assembly quality decline, so we can adjust the direction of the bearing 180 °, re-heating the other side to ensure that the bearing Heating evenly.
 

2.Bearing into the focus on skills

Assembly process to produce a special copper hammer to hit the bearing, while the bearing diagonal percussion to ensure that the bearings into the eccentric shaft in a balanced manner. In the eccentric shaft into the moving jaw process, with the hammer to hit the jaw, the use of interaction force will be eccentric shaft into the moving jaw, so do not damage the eccentric shaft bearings.

 

3.Bearing lubrication reasonable

The use of butter oiling device will be injected into the moving jaw grease, grease into the bearing for its space volume of about 50%, every 3-6 months to replace once. Oil change when the application of clean gasoline or kerosene cleaning roller bearing raceway, making the bearing lubrication is evenly uniform, under heavy load, high temperature under the action of a very good lubrication to extend the life of the jaw crusher bearing.
 

4.Pay attention to put into trial

Jaw crusher work should be in the thrust plate and adjust the seat between the injection of the right amount of grease, idle for some time, check the working current and voltage is normal and the crusher is abnormal ring to ensure that everything is normal, and then transport the stone to break jobs. In the feed port to do the buffer measures to avoid the direct impact of large stones crusher mouth, more than the size of the feed mouth to be a large stone to be allowed to enter the material after two blasting.
 
In the jaw crusher bearing assembly process, must be strictly in accordance with the instructions to operate to reduce the occurrence of bearing burns, thereby reducing the number of crusher downtime to improve the use of crusher.
