Slewing bearing is a kind of medium and large slew bearing design with a special structure, which can simultaneously bear large axial load, radial load and overturning moment, and other comprehensive loads. Next, our company will introduce the slew ring bearing design and how a slew ring work to you.
In general, the slewing ring bearing such as the excavator slew bearing has mounting holes, lubricating oil holes and sealing devices, which can meet the different needs of all kinds of hosts working under different working conditions. On the other hand, the turntable slewing bearing has the characteristics of compact structure, convenient rotating guide, easy installation, and easy maintenance, and is widely used in hoisting and conveying machinery, metallurgical machinery, mining machinery, construction machinery, port machinery, and automatic assembly line and other medium and large rotary devices.
Turntable bearing can be divided into four-point contact ball slewing bearing, double row ball slewing bearing, cross roller slewing bearing, three-row roller slewing bearing, and other structures according to different slewing ring design structural forms. The above-mentioned kinds of slewing ring bearing are divided into slewing bearing without gear, slewing ring bearing with external gear and slewing bearing with internal gear, and other different structures according to whether they have gear and the distribution of gear. The slew ring bearing design of slew ring bearing manufacturers also needs to pay attention to its different structural forms.
According to different structural characteristics of turntable slewing bearing and slewing ring definition, it can meet the needs of hosts under different load conditions. The four-point contact ball slewing bearing has a high dynamic load capacity and the cross roller slewing bearing has a high static load capacity. For three-row roller slewing bearing, due to improving the bearing capacity to the bearing height direction and various loads born respectively by different raceway and roller group, under the same loading conditions, the diameter of turntable bearing can be greatly reduced, therefore, the slew ring bearing design has the characteristics of making hosts more compact and is the turntable bearing with high bearing capacity.
