Bearing maintenance and precautions.

In the process of mechanical maintenance, bearing maintenance has high requirements for installation. Since the bearing does not have obvious external characteristics in appearance, it can be installed in either forward or reverse direction, which is extremely easy to reverse installation. In the process of bearing assembly, maintenance personnel are required to have a full understanding of the structure and installation requirements of the bearing, be familiar with the key points of safety technology, and install correctly according to the design requirements. The installation methods of circular cone bearing include "back-to-back" and "face-to-face". If the installation error will lead to axial movement and can not be adjusted; If there is a lack of understanding of the structure and installation of the bearing, it is easy to install reversely when facing the tight ring and loose ring of the plane bearing, resulting in the failure of normal operation after assembly and greater failure of mechanical equipment.

In the process of mechanical maintenance, fully understand the technical index information such as bearing code and model of the equipment, try to rotate the original model as much as possible, and avoid using alternative models. In practical work, some equipment often replace bearings, and the replaced bearings are very easy to burn out, which is usually directly caused by the difference of bearing models, the use of substitute bearings and the quality defects of bearings themselves. Due to the uneven quality of the bearings sold in the market, there is a phenomenon of shoddy bearing parts. The long-term use of low-quality bearing parts causes long-term wear and tear to the mechanical equipment and reduces the service life of the equipment. During mechanical maintenance, the rotating bearing shall avoid rotating the accessories in long-term inventory. At the same time, the bearing shall be visually inspected and the function shall be tested to ensure the bearing quality.

The bearing plays an important role in the normal operation of the machine. By maintaining lubrication, avoiding the immersion of foreign matters and overload and overspeed operation, the service life can be prolonged. During bearing maintenance, the causes of damage shall be analyzed and targeted measures shall be taken to ensure maintenance quality and improve equipment operation efficiency.
