SKF Bearing Application

wallpapers Industry 2020-12-23

Intense competition in the wind power market has prompted turbine developers to seek new ways to improve performance and minimize costs. By improving turbine design, improving performance, and increasing reliability, while reducing maintenance costs, it is under tremendous pressure to reduce the cost per MWh. Turbines are usually operated in harsh conditions (offshore, cold climates or remote areas), which limits their performance and reliability. High maintenance costs and long delivery times for replacement parts make energy production uncompetitive.
 
As profit margins shrink, turbine suppliers are increasingly focusing on operation and maintenance (O&M) efficiency, while aiming for a larger share of the service market.
 
Any measure that prevents the service itinerary can increase the return on investment and reduce the average cost of energy. SKF has worked with leading OEMs for many years to optimize turbine performance, reliability and energy output. SKF has designed and developed bearings, seals, condition monitoring systems and lubrication systems, which can increase the cost of wind power generation and reduce lubricant consumption.
 
Features of sliding bearings
 
Compared with rolling bearings, sliding bearings have the advantages of large carrying capacity, stable and reliable operation, low noise, impact resistance, vibration absorption, and splitting. The characteristic is that the fluid film bearing can work at a very high speed, with high rotation accuracy, low friction coefficient and long life.
 
Sliding bearings are widely used in gas turbines, high-speed centrifuges, high-speed precision machine tools, internal combustion engines, rolling mills, railway locomotives and vehicles, hydraulic turbines, meters, chemical instruments, rubber machinery and astronomical telescopes.
 
Design of sliding bearing
 
The design of sliding bearing mainly includes the following contents: ①Select and determine the structure of the bearing; ②Select the bearing structure and bearing material; ③Determine the bearing structure parameters and calculate the bearing capacity; ④Select the lubricant, lubrication method and lubrication device.
