Tapered roller bearings are widely used in the automotive industry

Tapered roller bearing is a widely used mechanical support. Its function is to support the shaft and the parts on the shaft under the condition of ensuring the bearing has enough life, and make relative rotation, swing and other movements with the frame, so that the friction between the rotating pair is reduced as far as possible, in order to obtain higher transmission efficiency. Tapered roller bearings mainly bear combined radial and axial loads. Bearing capacity depends on the raceway Angle of the outer ring, and the greater the Angle, the greater the bearing capacity. Tapered roller bearings have tapered inner and outer raceways with tapered rollers arranged in between. The projection lines on all conical surfaces meet at the same point of the bearing axis. This design makes tapered roller bearings particularly suitable for bearing compound (radial and axial) loads. The axial load capacity of bearings is mostly determined by the contact Angle α. The larger the α Angle, the higher the axial load capacity. The Angle is represented by the calculated coefficient E. The larger the e value and the greater the contact Angle, the greater the applicability of bearing under axial load.   Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries. Since the founding of new China, China's tapered roller bearing industry has achieved rapid development. However, at present, from the point of view of product development, product quality level and production and manufacturing level, there is a large gap with the world tapered roller bearing manufacturers, most of them are at the imitation level, and generally low-grade tapered roller bearings account for the majority. Therefore, in recent years, China has been increasing efforts in scientific research, and has made certain progress in the level of products. At present, the development trend of China's tapered roller bearing industry is as follows: increase production scale, improve production investment; Strengthen scientific research and innovation, especially focusing on bearing life and reliability; Continuously adjust a wide range of product mix, deepen the taper roller bearing structure design and application technology research, expand the special high-precision and high-value-added taper roller bearing capacity; Focus on the development of speed, accuracy, high reliability, long life, low friction, low vibration, low noise, high-tech bearing products.
