011.40.900 Single row ball slewing beairng with outer gear or light type slewing bearing for DEERE GRADERS ( Engineering Machinery )

Motor graders are the main machinery used for shaping and leveling operations in earthwork, and are widely used in large-area ground leveling operations such as highways and airports. The reason why the grader has a wide range of auxiliary work capabilities is that its moldboard can complete 6 degrees of movement in space. They can be carried out individually or in combination. In the construction of roadbed, the grader can provide sufficient strength and stability for the roadbed.

The slewing bearing used in the grader is mainly a single-row ball slewing bearing. The main function of the slewing bearing is to connect the scraper and the traction bracket, and to drive the scraper to rotate and adjust the angle. Carry small radial and axial forces.

The operating conditions of the motor grader are generally poor, and the selection of slewing bearings with appropriate structure and material can effectively increase the bearing capacity and impact resistance. The safety, stability and service life of the equipment can be improved.

The motor or reducer drives the pinion to rotate, and the pinion drives the slewing bearing to rotate, so as to change the angle of the scraper connected to it.

 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.
