There are two jaws in the jaw crusher, which can be divided into the fixed jaw and the moving jaw. The moving jaw is a kind of very important component for the jaw crusher. As a result, the maintenance for the moving jaw is very necessary. The attrition of the inner hole of the moving jaw of the jaw crusher is very common. Through many years’ practical experience, the experts of Henan Hongxing Mining Machinery have summarized the following require methods for the attrition of the inner hole of the moving jaw of the jaw crusher.
The first is the welding method for the inner hole. This method is suitable for the moving jaw made of the casting steel. Uniformly surface a layer on the surface of the worn inner hole with the manual arc welding. Then expand and process the inner hole again according to the requirements of the tolerance so that it can be well matched with the outer diameter of the bearing. In terms of this method, the welding layer for the inner hole is relatively thin, while the wall of the moving jaw is relatively thick. As a result, there will be no deformation in surfacing process. In addition, there are no special requirements for the welding process. However, in the processing procedure for the inner hole, you should control the verticality of the center line of the inner hole and the moving jaw to ensure the cooperating relationship and fit precision between the moving jaw and other components.
The second way is the bushing for the inner hole. In the actual operation, the diameter of the inner hole of the moving jaw should be matched with the outer diameter of the rolling bearing. The matching precision and the tolerances should be processed according to the design of the original draft. The bearing should be installed at the inner hole of the moving jaw. This method is not limited by the material of the moving jaw. Therefore, this method is very suitable for the material of the moving jaw with poor welding performance.
