Roller Slewing Bearing excavator small crane internal gear

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.

Beschreibung

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.

We pay attention to quality inspection of every production and purchase process.
