According to different structural types, Fenghe slewing bearings can be divided into four-point contact ball slewing bearings, double-row angular contact thrust ball slewing bearings, crossed cylindrical roller slewing bearings, crossed tapered roller slewing bearings, and three-row cylindrical roller combined slewing bearings. The above-mentioned various types of bearings are divided into different structures such as gearless external gear or internal gear according to whether they have teeth and the distribution of gear teeth.
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.
