Do you know the role and application of taper roller brg?

taper roller brg have a tapered inner ring and an outer ring raceway in between. All projection lines of the tapered surface converge at the same point on the bearing axis. This planning makes tapered roller bearings particularly suitable for receiving loads (radial and axial). The axial load of the bearing is largely determined by the touch angle α; α larger the viewpoint, the higher the axial load. The viewpoint size is indicated by the calculation factor e; The higher the e-value, the larger the touch viewpoint and the greater the suitability of the bearing to axial loads.

taper roller brg are generally separated, i.e. a tapered inner ring assembly consisting of an inner ring with rollers and a retention frame assembly can be separated from the tapered outer ring (outer ring).

Tapered roller bearings are widely used in cars, rolling mills, mining, metallurgy, plastic machinery and other industries.

The secondary reason for the scarring of taper roller brg during the installation process is that the bearing is skewed in the inner and outer rings during assembly of the unit; Or a charging load occurs during the installation and assembly process, which eventually constitutes a bearing scar.

Precautions for the use of bearings are as follows:

(1) Insist on clean tapered roller bearings and their surroundings

Even small dirt that is invisible to the eye can have a bad effect on the bearing. Therefore, it is necessary to insist on cleaning the surrounding area so that dust does not invade the bearing.

(2) Use it carefully

In the use of taper roller brg strong impact, will produce scars and indentation, become the cause of failure. In severe cases, cracks and cracks will occur, so be sure to pay attention.

(3) Use appropriate operating tools

Avoid replacing existing tools with the right ones.

(4) Pay attention to the rust of tapered roller bearings

When operating the bearing, sweat on the hands can become the cause of rust. Be careful to operate with clean hands, and it is best to wear gloves as much as possible.

taper roller brg use hearing to identify irregular work, such as an experienced operator using an electronic stethoscope to detect abnormal noise in a part. If the bearing is in good working condition, it will announce a low whining sound, if it announces a sharp hiss, squeak and other irregular sounds, it generally indicates that the bearing is in poor working condition.

1. Tile surface corrosion: spectral analysis found that the concentration of non-ferrous metal elements was abnormal; Many submicron-scale wear particles of non-ferrous metal composition appear in the iron spectrum; Smooth oil moisture overrun, acid number overrun.

2. External strain of the journal: there are iron cutting abrasive grains or black oxide particles in the iron spectrum, and there is tempering color on the metal surface.

3. Corrosive appearance of the journal: spectral analysis found that the concentration of iron element was abnormal, there were many submicron particles of iron components in the iron spectrum, and the moisture overrun of smooth oil or acid value overrun.

4. External strain: cutting abrasive grains were found in the iron spectrum, and the abrasive grain composition was non-ferrous metals.

5. Tile back fretting wear: Spectral analysis found that the iron concentration was abnormal, and there were many submicron wear particles of iron components in the iron spectrum, and the moisture and acid value of smooth oil were abnormal.
