Cylindrical roller bearing if in good continuous rotation state will issue a low whine or humming sound. If a sharp hiss, squeak and other irregular sound, often indicates that the bearing is in bad continuous rotation condition, sharp squeak noise may be due to improper lubrication caused by, improper bearing clearance will also cause metal sound.Dents in the bearing outer raceway can cause vibration and result in a smooth, crisp sound.If there is an intermittent noise, this indicates that the

The grinding process is a common method of metal cutting in the machinery manufacturing industry, and is widely used in the bearing processing industry. The heat-treated and quenched bearing parts may appear as a net-like crack or a more regular arrangement of small cracks during the grinding process, called grinding cracks, which not only affect the appearance of the bearing parts, but more importantly.also directly affect the quality of the bearing parts. This article shares the characteristic

Bearing use factors mainly refers to the installation and adjustment, use and maintenance, maintenance and repair of the technical requirements. According to the technical requirements of bearing installation, use, maintenance and repair, the load, speed, working temperature, vibration, noise and lubrication conditions of the running spherical roller bearings are monitored and checked, and abnormalities are found to immediately find the causes and make adjustments to restore them to normal. The

1. Friction compatibility The performance of the shaft diameter in direct contact with the shaft tile to prevent adhesion and the formation of boundary lubrication.The material factors that affect the friction compatibility of the friction pair are:(1) into the sub-material metallurgy into the degree of difficulty in the composition of the alloy.(2) material and lubricant affinity.(3) The friction factor of the material in the unlubricated state.(4) The microstructure of the material.(5) The the

In the actual application of cylindrical roller bearings, often encounter the problem of bearing heat, how do you need to deal with it?First of all, we need to understand the causes of the column roller bearing fever.Cylindrical roller bearings in the work of more than normal temperature may have the following reasons:1, bearing and journal fit uneven or contact surface is too small (with too small clearance), the unit area of the specific pressure is too large, most of this situation occurs in
