Common vertical mill equipment bearing lubrication

Guidance: The importance of lubrication for vertical mill equipment is not to be said, especially bearing lubrication is more important. A simple analysis of two common ways of bearing lubrication. First of all, analyze the way of common vertical mill equipment bearing lubrication.

Lubrication is of great importance to the importance of vertical mill equipment, especially bearing lubrication is more important. A simple analysis of two common ways of bearing lubrication. First, analyze the lubrication of the common vertical mill equipment bearing lubrication. Injection lubrication is a lubrication method that uses high-pressure injection to inject lubricant into the bearing and lubricate the bearing. When the bearing is running at high speed, the rolling elements and the cage are also rotated at a relatively high rotational speed, thereby forming an air vortex around the bearing. If the general lubrication method is used, the lubricating oil does not easily reach the lubrication portion. On the other hand, it is difficult to maintain the lubricating oil at the lubricating portion due to the centrifugal force generated at a high speed.

In order to ensure that a sufficient amount of lubricating oil is supplied to the high-speed bearing, the lubricating oil must be forcedly injected from one end of the bearing to be lubricated, and then re-introduced into the tank from the other end. The lubrication system should be designed so that the high pressure nozzle is positioned between the inner ring and the center of the cage and the lubricant is raked to the outer race by centrifugation. In order to effectively lubricate the bearing, the injection speed of the lubricating oil should be not less than 15 m/s. From the perspective of operating speed, injection lubrication is often used for bearings that operate at higher speeds at low or medium loads. From the direction of the bearing force, the injection lubrication is often used for bearings on vertical or inclined shafts, and the lubricant is usually injected directly into the bearing.

Oil and gas lubrication is also one of the common ways of bearing lubrication in vertical mill equipment. Oil and gas lubrication is generally suitable for applications where the bearing speed is high. The oil and gas lubrication system mixes a small amount of lubricating oil with a certain pressure of gas and then supplies it to the bearing. This method is suitable for high speed applications, such as machine tools, and the refining and chemicals industry is generally less used. The above is a brief introduction to the lubrication of two common vertical mill equipment bearings, namely injection lubrication and oil and gas lubrication.
