How much do you know about taper roller auto bearings?

The ability of the taper roller auto bearing to bear the axial load depends on the contact angle, that is, the angle of the raceway of the outer ring. The greater the angle, the greater the axial load capacity. The most commonly used taper roller auto bearings are single row taper roller auto bearings. In the front hub of the car, a small double row tapered roller automatic bearing is used. Four-row taper roller auto bearings are used in high-performance machines such as large cold and hot rolling mills.

What is the structure principle and function of tapered roller automatic bearing?

Taper roller auto bearings have tapered inner and outer raceways with tapered rollers arranged between them. The projected lines of all cone surfaces meet at the same point on the bearing axis. This design makes tapered roller automatic bearings particularly suitable for combined (radial and axial) loads. The axial load bearing capacity of the bearing is mainly determined by the pressure angle α; The greater the α angle, the higher the axial load capacity. The size of the angle is represented by the calculation coefficient e; the greater the value of e, the greater the contact angle and the greater the applicability of the bearing to bear the axial load.

Taper roller auto bearings are usually disassembled, i.e. the tapered inner ring consisting of inner ring with roller ring can be installed separately from the tapered outer ring (outer ring).

Taper roller auto bearings are widely used in automobiles, rolling mills, mining, metallurgy, plastics machinery and other industries.

What is the difference between taper roller auto bearings and angular contact ball bearings?

Taper roller auto bearings and angular contact ball bearings have different rolling elements, one is a ball (point contact) and the other a roller (line contact). Of course, the line contact has a large load-bearing capacity and strong rigidity. The angular contact mainly bears the axial load; The tapered roller automatic bearing bears the axial and radial load and transmits the unidirectional axial load. Angular bearings are generally used in parts with low pressure and high speed, such as water pumps. Washing and so on. Tapered roller auto bearings are generally used in relatively low speed and high pressure parts, such as automotive spindles, etc.

What should be considered after installing the taper roller auto bearing?

After installing the tapered roller automatic bearing, refill the prescribed lubricant, then run a test run to check the noise and temperature of the tapered roller automatic bearing. The test run should be carried out under the condition that the minimum load is met and run at a large speed range at medium and low speeds. Under no circumstances should a bearing be approached without load and accelerated to high speed, as this can cause the rollers to slide on the raceway and damage the raceway.
