Three row roller external gear slewing bearing for Lebherr WS 8100 Dynamic compaction Machine

Slewing bearings are widely used. Construction machinery is the initial application field of slewing bearings and is also widely used, such as earthmoving machinery, excavators, dismantling machines, stackers and reclaimers, graders, road rollers, dynamic compaction machines, rock drilling machinery, roadheaders, etc.

The slewing bearing used in the dynamic compaction machine is required to be able to withstand a certain axial force, overturning moment and large impact force, and its main function is to support the rotation of the upper end mechanism and the control mechanism.

Selecting the appropriate slewing bearing can effectively increase the bearing capacity, withstand greater impact force, make the equipment run smoothly and have a longer service life. The motor or reducer drives the pinion to rotate, and the pinion drives the slewing bearing to rotate, so that the upper mechanism connected to it rotates accordingly. Selecting the appropriate slewing bearing can effectively increase the bearing capacity, withstand greater impact force, make the equipment run smoothly and have a longer service life.

The slewing mechanism is composed of a supporting device, a slewing bearing and a turntable. The slewing bearing is an important force-bearing component.

The slewing mechanism is composed of a supporting device, a slewing bearing and a turntable. The slewing bearing is an important force-bearing component. It not only bears the dead weight of the rotating part of the crane, but also bears the vertical force of the lifting load and the force of the tipping moment. During use, there must be wear and tear, and the performance of related mechanical parts will gradually deteriorate or even be damaged.

  FAQ :  

1   LW Slewing Bearing Heat Treatment

Heat Gear Slewing Bearings are in the majority of cases supplied with spur tooth. Stub teeth also is ok.There are two kinds of tooth hardening. They are normalizing and tempering, According to the different applications, there are two ways of quenching. They’re whole tooth quenching and single-tooth quenching. Single-tooth quenching can be divided into tooth surface & root quenching and tooth surface quenching.

2 . The Calculation of Slewing Bearing.

Static load capacity

The determined loads must be multiplied with a factor fstat allocated to the application. The product Fa’ or Mk’ must be below the static critical load curve of the selected bearing.

With regard to radial loads in load combinations

Fa = axial load
Fr = radial load
Mr = tilting moment

3 Protection Against Corrosion

We make  Protection Against Corrosion on surface of bearing,and make couple of packing paper.

4.Customize.

Yes,we have professional technical terms.

5.Warranty:
General 1 year

6. Reliable reputation.
