The German version of the jaw crusher toggle plate, during the working process of the crusher, is subjected to a large impact and extrusion load, and the working environment is harsh, so it is strongly worn.It is both a vulnerable part and an insurance part. br/>
During normal work, because the toggle plate and the elbow pad cannot be lubricated well, that is, the two cannot form an oil film. Furthermore, dust will fall into Inside. So there is a state of dry friction and abrasive wear between the toggle plate and the toggle pad. This causes the toggle plate and the toggle pad to wear quickly and the service life is very low. Therefore, extending the service life of the toggle plate is very important. The following article mainly introduces the improvement measures for the wear of the toggle plate of the German version of the jaw crusher.
1 Change the sliding type to the rolling type
The elbow of the jaw crusher swings up and down with the movable jaw (or connecting rod), and the rolling angle in the elbow pad is about 10, that is, when the swing angle of the toggle does not exceed 10, the elbow is at The elbow pad is rolled without sliding. Generally, the swing angle of the toggle plate is not more than 10, so this type of elbow and the toggle pad are rolling, so as to realize the change from sliding to rolling, improve transmission efficiency, reduce wear and extend Its service life.
2 Changing the lubricating fluid between the elbow and the elbow pad
The wear of the elbow and the elbow pad is not affected by the movement characteristics In addition to the impact, there are still lubrication conditions and dust. Lubricating oil is used for the elbow and elbow pad of the German version of jaw crusher. If the lubrication effect is not ideal, water lubrication can be used for this purpose. Water can take away the friction. The heat can wash away the dust, thereby prolonging the service life of the elbow and elbow pad.
3 Use a reasonable elbow and elbow pad structure
Based on the viewpoint of using rolling instead of sliding, and making the elbow pad easy to replace and prolong its life, the elbow pad is made into a cylindrical shape, and its two ends are square for fixing. When one side is worn out, the other side can be used again. Use 4 times in turn to extend the service life. The elbow and elbow pad of this structure have been used in foreign crushers.
4 Improve the shape of the mating surface of the elbow pad and the elbow seat.
In the old-fashioned crusher, the mating surfaces of the elbow pad and the elbow seat adopt a general shape. With this shape, the elbow pad is squeezed by a long-term impact, and due to deformation and expansion, the elbow pad should be replaced It is difficult to remove in the elbow seat groove. Therefore, the shape of the mating surface of the elbow pad and the elbow seat groove should be changed to a trapezoid.
