This is the case when the bearing of LY’s limestone crusher is heated. If a shaft with a length of 3m is installed in summer, the maximum shrinkage in winter (when it is stopped) can be close to 3mm. Generally, the axial gap is adjusted with a gasket (pressing lead wire method), and some can also be adjusted with a screw or a thrust ring. (Reduce the opening of the oil return pipe valve at the safety valve of the oil station) Central control operation and on-site inspection personnel should be sufficiently alert to abnormal conditions of equipment bearing temperature rise.
When the oil level approaches the lower mark, the lubrication condition deteriorates. Only when the oil level is displayed on the upper scale line can the operation need be met.23mm gasket, and the least part was hardly added with a gasket.
If the heating temperature is too high due to improper temperature control, the bearing will be tempered and the hardness will decrease, and the bearing will be easily worn, peeled, temperature rised too SKF Bearing Suppliers fast or even cracked during operation. It takes a lot of effort to troubleshoot the situation of bearing irregularities. In the following, we will analyze and summarize the specific problems in the design, installation, lubrication, assembly and other links based on several typical cases encountered by the author during the production and debugging process, for your reference.
As a result, the outer race of the bearing could not produce axial displacement, which could not meet the expansion requirements of the shaft and was burned. The simplest method is to use a copper rod and a hand hammer to strike the bearing races with interference fit symmetrically in a certain order to make the bearing smoothly press in.
