The role and use of tapered roller bearings

Tapered roller bearings mainly bear radial and axial combined loads. The bearing capacity of the bearing depends on the raceway angle of the outer ring. The larger the angle, the greater the load carrying capacity. This type of bearing is a split type bearing, which is divided into single row, double row and four row tapered roller bearings according to the number of rows of rolling elements in the bearing. The clearance of the single row tapered roller bearing needs to be adjusted by the user during installation; the double row and four row tapered roller bearing clearances are given according to the user's requirements when the product leaves the factory, and no user adjustment is required.

Tapered roller bearings have a conical inner ring and an outer ring raceway, and tapered rollers are arranged between the two. The projection lines of all conical surfaces converge at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for withstanding composite loads.

Although the quality of tapered roller bearings is better in all aspects, rolling bearings are precision components, and their use must be carried out with caution. No matter how high-performance bearings are used, if not used properly, the expected high performance will not be achieved. There are several precautions regarding the use of bearings:

(1) Keep the tapered roller bearing and its surroundings clean.

Even small dust that is invisible to the eyes can have a bad effect on the bearings. Therefore, keep the area clean so that the dust does not intrude into the bearing.

(2) Use with caution.

In the use of the tapered roller bearing strong impact, it will produce scratches and indentations, which is the cause of the accident. In severe cases, it will crack and break, so be careful.

(3) Use the appropriate operating tools.

Avoid using existing tools and use the right tools.

(4) Pay attention to the corrosion of tapered roller bearings.

When operating the bearing, the sweat on the hand can cause rust. Be careful to use a clean hand and try to wear gloves. Tapered roller bearings use auditory to identify irregular movements. A common method is to use an electronic stethoscope to detect abnormal noise in a part that is experienced by an operator. If the bearing is in good working condition, it will make a low humming sound. If it is a sharp squeaky tapered roller bearing, arpeggio and other irregular sounds, it usually indicates that the bearing is in poor working condition.
