For jaw crusher, in production, the function of sliding bearing can not be ignored. Generally speaking, in order to ensure that the sliding bearing can play its role smoothly, it is necessary to ensure that the selected sliding bearing meets the production requirements, and ensure the correct assembly process. Here is to introduce the selection and assembly of this part.
The choice of sliding bearing
In the jaw crusher, the movable jaw suspension shaft, eccentric shaft and connecting rod shaft are all supported by the sliding bearing. In order to reduce the friction resistance and wear between the shaft and the bearing, the sliding bearing lining is usually made of wear-resistant alloy bearing lining. The correct selection and use of alloy materials are very important. Due to the improper selection of materials, the equipment is damaged and the service time of the bearing is shortened In addition, when choosing, we should pay attention to whether the model of sliding bearing matches the model of jaw crusher;
Assembly of sliding bearing
Step 1. Put all the broken tile linings on the removed tile liner outer seat, and clean the outer seat with diesel or gasoline until there is no oil stain;
Step 2: after heating on the fire, apply a thin layer of melted common tin water on the inner surface of the cast tile lining;
Step 3: synthesize the two half tile bases into one, install the wooden core box, pour the melted alloy into the gap between the tile base and the core box, take out the core box after solidification, add the poured tiles according to the drawing requirements, remove the oil groove or oil groove after processing, and then saw with a hacksaw;
Step 4: after the red lead is painted on the site, rotate the shaft with the shaft, and then remove the tile and scrape off the worn part of the red lead with a scraper until the worn part of the red lead is more than 70%. When running in with the shaft, the bearing seat shall be covered to increase the weight and compactness;
The above mainly introduces the selection and assembly process of the sliding bearing of jaw crusher. In the actual selection, the problems that need to be paid attention to are the model and the wear resistance of the parts. In the assembly, as long as the steps are followed, these two aspects have a great impact on the equipment work, so it needs to be carried out carefully.
