Single row ball external gear slewing bearing 011.40.1000 for NICHOLS Concrete Pump Truck

Concrete pump truck is a machine that uses pressure to continuously transport concrete along the pipeline. It consists of a pump body and a delivery pipe. According to the structure, it is divided into piston type, extrusion type and hydraulic diaphragm type. The pump body is installed on the chassis of the car, and then equipped with a retractable or inflection boom to form a pump truck.   The slewing bearing used by the concrete pump truck is generally a single-row ball slewing bearing, which needs to carry a certain axial force and overturning moment. The main function is to support and rotate, and to control the direction of the cantilever.

Selecting a slewing bearing with an appropriate structure can effectively increase the load, 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.

Technical parameters required for slewing bearing selection as below:
1).Slewing bearing load (Includes axial load, radial load and tilting moment)  
2). Percentage of each load and its occupation time
3). Speed or number of revolutions of the slewing bearing under each load
4).Circumferential force acting on the gear
5).Dimensions of the slewing bearing
6). Other operating conditions

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

  1. Reliable reputation.
