Innovation in Bearing Lubrication Technology

Innovation in bearing lubrication technology is a crucial approach to improving mechanical transmission efficiency and reducing energy consumption. The research and development of new lubricants and the application of intelligent lubrication systems have already brought significant economic and environmental benefits to the machinery industry.

What is Slewing Bearing?

The slewing beaing is an integrated power transmission device that combines the functions of a slewing bearing and a drive system. It mainly consists of components such as a motor, a reducer, a slewing bearing, and a brake. The motor provides power, which is decelerated and torque – increased by the reducer and then drives the slewing bearing to rotate, enabling the circular motion of equipment components. The slewing beaing can precisely control the rotation angle and speed, and has the advantages of a compact structure, convenient installation, and high transmission efficiency. It is commonly used in fields such as solar tracking systems, industrial robots, and port machinery. In a solar tracking system, the slewing beaing can accurately adjust the angle of the solar panel according to the position change of the sun, improving the solar energy utilization rate and effectively enhancing the working performance and automation level of the equipment.

Dilemmas of Traditional Lubrication Methods

Traditional bearing lubrication mostly uses mineral oil or grease, which can meet certain lubrication requirements under normal working conditions. However, under extreme conditions such as high – speed, heavy – load, and high – temperature, their limitations become prominent. Mineral oil is prone to oxidation and deterioration at high temperatures, resulting in a decline in lubrication performance and an increase in the friction coefficient. This not only reduces the transmission efficiency but also shortens the bearing life due to excessive wear. Grease has poor fluidity during high – speed operation, making it difficult to achieve full lubrication and likely to cause local overheating, further increasing energy consumption. Therefore, it is urgent to develop new lubricants.

Synthetic Lubricants: The “New Favorites” in the Lubrication Field

Advantages and Applications of Synthetic Ester Lubricants

In recent years, synthetic lubricants have become a research hotspot, and synthetic ester lubricants have performed particularly well. They have excellent thermal stability, low volatility, and good lubrication performance, showing significant advantages under high – temperature and high – speed conditions. They can form a more stable and thinner lubricating film on the bearing surface, effectively reducing the friction resistance and greatly improving the transmission efficiency. For example, in the high – speed bearings of aircraft engines, the use of synthetic ester lubricants can significantly reduce the energy loss caused by friction, improve the fuel efficiency of the engine, and reduce carbon emissions.

Characteristics and Value of Polyalphaolefin (PAO)

Polyalphaolefin (PAO) is also a synthetic lubricant with excellent performance. Its characteristics of a low pour point and a high viscosity index enable it to maintain good fluidity in low – temperature environments, ensuring normal bearing lubrication. At high temperatures, its viscosity changes little, and it can maintain a stable lubrication effect. Using PAO lubricants in the gearbox bearings of wind turbines can not only reduce the friction torque during low – temperature startup and decrease energy consumption but also ensure reliable bearing lubrication during high – temperature operation and extend the equipment maintenance cycle.

Intelligent Lubrication Systems: Ushering in a New Era of Lubrication

Working Principle of Intelligent Lubrication Systems

In addition to new lubricants, intelligent lubrication systems have brought a revolutionary change to bearing lubrication technology. The traditional fixed – time and fixed – quantity lubrication method cannot be adjusted in real – time according to the actual operating conditions of the bearing, which is likely to lead to waste of lubricants or insufficient lubrication. Intelligent lubrication systems use sensors, controllers, and actuators to achieve precise monitoring and control of the bearing lubrication state. The sensors are installed at key positions of the bearing to collect parameters such as temperature, speed, and load in real – time. The controller uses advanced algorithms to accurately calculate the required lubricant quantity and time based on these data and then controls the actuator to supply oil precisely, ensuring that the bearing is always in the optimal lubrication state.

Application Results of Intelligent Lubrication Systems in Large – Scale Equipment

In large – scale industrial equipment, such as mining equipment, intelligent lubrication systems show their full advantages. Such equipment operates in harsh environments with frequent load changes, and traditional lubrication methods are difficult to meet the requirements. Intelligent lubrication systems can dynamically adjust the lubrication strategy according to the actual operating conditions of the equipment, which can not only reduce the consumption of lubricants but also reduce the equipment failure rate and improve production efficiency. For example, after an electric – wheel dump truck in a large open – pit mine adopted an intelligent lubrication system, the lubrication effect of the wheel – side reducer bearings was significantly improved, the number of maintenance times was greatly reduced, the vehicle operation efficiency increased by 15%, and the lubricant consumption decreased by 30%.

Extended Functions of Intelligent Lubrication Systems

Intelligent lubrication systems can also be integrated with the equipment remote monitoring system to achieve remote diagnosis and fault warning. By analyzing the lubrication data, potential bearing fault hazards can be detected in advance, and maintenance measures can be taken in a timely manner to avoid huge losses caused by sudden equipment failures.

Future Blueprint of Lubrication Technology

With the development of emerging technologies such as the Internet of Things, big data, and artificial intelligence, there is broad space for innovation in bearing lubrication technology. In the future, the research and development of lubricants will pay more attention to green environmental protection and multi – function integration. For example, products with functions such as lubrication, anti – wear, and self – repair will be developed to further improve the comprehensive performance of bearings. Intelligent lubrication systems will develop towards intelligence, networking, and collaboration, realizing the sharing and optimized allocation of lubrication resources among multiple devices and constructing an efficient and energy – saving industrial lubrication ecosystem.

Prices of Slewing Bearings

There are many factors affecting the prices of slewing bearings. Firstly, raw materials play a significant role. High – quality steel has a high cost, and products made from it have excellent performance and long service life, thus having a high price. Secondly, slewing bearings with complex manufacturing processes and high – precision requirements need advanced equipment and strict quality control, which will also increase the price accordingly. Moreover, the larger and more special the size and specifications are, the greater the processing difficulty and material consumption, and the higher the price will be.
