slewing ring bearing assembly Internal gear with Good quality
The slewing bearing is a large bearing with a special structure that can withstand large axial loads, radial loads and overturning moments at the same time. Under normal circumstances, the slewing bearing itself has mounting holes, lubricating holes and sealing devices to meet various requirements. The different requirements of various hosts working under different working conditions. On the other hand, the slewing bearing itself has the characteristics of compact structure, guiding rotation, convenient installation and easy maintenance, etc. It is widely used in lifting and transporting machinery, mining machinery, construction engineering machinery, port machinery and missile launchers. Wait for a large rotary device.
slewing bearing for excavator
The slewing device is composed of a turntable, a slewing bearing and a slewing mechanism. The outer race of the slewing bearing is connected with the turntable by bolts, the inner race with teeth is connected with the underframe by bolts, and rolling bodies are arranged between the inner and outer races. The vertical load, horizontal load and overturning moment of the excavator working device acting on the turntable are transmitted to the underframe through the outer race, rolling element and inner race of the slewing bearing. The housing of the slewing mechanism is fixed on the turntable, and a pinion gear is used to mesh with the ring gear on the inner race of the slewing bearing. The pinion can rotate on its own axis or revolve around the centerline of the turntable. When the turning mechanism is working, the turntable will rotate relative to the chassis.
