Nach verschiedenen Konstruktionstypen können Fenghe-Großwälzlager in Vierpunktkugel-Großwälzlager, zweireihige Axial-Schrägkugel-Großwälzlager, gekreuzte Zylinderrollen-Großwälzlager, gekreuzte Kegelrollen-Großwälzlager und dreireihige Zylinderrollen-Großwälzlager unterteilt werden Großwälzlager. Die oben erwähnten verschiedenen Arten von Lagern werden in verschiedene Strukturen unterteilt, wie z. B. getriebelose Außenverzahnung oder Innenverzahnung, je nachdem, ob sie Zähne und die Verteilung der Zahnradzähne haben.
Due to the different working conditions of slewing bearings, most of them work under eccentric load. In addition to bearing axial load and radial load, the bearing must also overcome the effect of overturning moment. Therefore, the bearing selection calculation is based on the load-moment diagram. The curve is the method commonly used by major manufacturers at present as the selection method of slewing bearings
After the slewing bearing is installed, the appropriate amount of grease should be filled and the slewing bearing should be filled to make the grease evenly distributed. The slewing bearing will inevitably lose part of the grease after working for a period of time. -Lubrication should be added once after 100 hours. For slewing bearings that work in high-temperature environments or dusty conditions, the cycle should be appropriately short. When the machine is shut down for a long time, it must be filled with sufficient grease.
