Tapered roller bearings are widely used in the automobile industry

Tapered roller bearing is a widely used mechanical support. Its function is to support the shaft and the parts on the shaft, and make relative rotation, swing and other movements with the base under the condition that the bearing has sufficient life, so as to reduce the friction between the rotating pairs as much as possible, so as to obtain higher transmission efficiency.
Working principle and application of tapered roller bearing
Tapered roller bearing mainly bears radial and axial combined load. The bearing capacity depends on the raceway angle of the outer ring. The larger the angle, the greater the bearing capacity. Tapered roller bearings have tapered inner race and outer race raceways, and tapered rollers are arranged between them. The projection lines of all conical surfaces meet at the same point of the bearing axis. This design makes the tapered roller bearing particularly suitable for bearing compound (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact angle α Determined; α The greater the angle, the higher the axial load capacity. The angle is expressed by the calculation coefficient e; The greater the e value, the greater the contact angle, and the greater the applicability of the bearing to bear axial load.
Tapered roller bearings are usually of the separated type, that is, the conical inner race assembly composed of the inner race with roller and cage assembly can be installed separately from the conical outer race (outer race).
Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
Development trend of tapered roller bearings in China
Since the founding of the People's Republic of China, China's tapered roller bearing industry has made rapid progress. However, from the perspective of product development, product quality, production and manufacturing level, there is a big gap with the high-end tapered roller bearing manufacturers of Guojiu. Most of them are at the level of imitation, 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 product level.
At present, the development trend of tapered roller bearing industry in China is as follows: increase production scale and increase production investment; Strengthen scientific research and innovation, especially focusing on bearing life and reliability; Constantly adjust a wide range of product combinations, deepen the structural design and application technology research of tapered roller bearings, and expand the special high-precision and high-value-added tapered roller bearings; Focus on developing bearing products with high speed, accuracy, reliability, long service life, low friction, low vibration, low noise and high technology.
