Oil air lubrication can be used to
High speed electric spindleThe lubrication method for work not only ensures long-lasting lubrication of bearings, but also suppresses the temperature rise of bearings. We should pay attention to the following issues when using oil and air lubrication:
Firstly, the determination of oil supply quantity and oil supply cycle: In order for the electric spindle to complete high-speed operation, supplying the appropriate amount of oil to the bearings has become a very important goal. The fuel consumption of bearing oil and air lubrication needs to be calculated according to the bearing scale parameters. The reasonable lubrication cycle for high-speed bearings is 3-10 minutes per time. For specific conditions, please refer to the recommended values provided by the bearing supplier.
Secondly, daily maintenance and handling: When using the oil and gas lubrication system, it is necessary to prevent leaks in the oil and gas discharge pipelines. If leaks occur, it will cause problems with the transportation of lubricating oil. Therefore, it is necessary to regularly check the condition of pipelines and oil flow in the operation of oil and gas lubrication systems. We also need to pay attention to the back pressure of the spindle lubrication channel and cavity. When the back pressure is too high, it will affect the speed of oil and gas transportation. When the back pressure is equal to the oil and gas pressure, the oil and gas will not move, which will cause the lubricating oil to be unable to reach the bearing direction. Therefore, it is necessary to pay attention to whether the oil and gas flow is outstanding in daily inspections. The selected oil and gas lubrication equipment should have oil and gas pressure detection and alarm functions, so as to announce hidden danger alarms when the bearing chamber back pressure rises, pipeline leaks and blockages occur, ensuring the high-speed operation of the electric spindle.
Thirdly, tighten air quality: In addition to the above-mentioned fuel supply quantity and cycle, the quality of compressed air is a key factor in the high-speed operation of electric spindles. Tightening air is not only the driving force for transporting lubricating oil, but also affects the working life of bearings. Dust impurities, moisture, and other factors in the compressed air are serious threats to the lifespan of bearings. Therefore, it is essential to provide high-precision air source filtration and dry system for the oil and gas lubrication equipment of the electric spindle.
