Tapered roller bearings are widely used in mechanical support. Its function is to ensure that there is enough in the bearing life conditions, to support the shaft and shaft parts, and the relative rotation, swing movement and rotation of the frame and between the friction pairs to reduce as much as possible, in order to obtain the high transmission efficiency.
The principle and application of cross roller bearings working
Tapered roller bearings are mainly bears radial, axial joint load radial based. Raceway angle bearing capacity depends on the outer ring of the bearing capacity, the larger the angle the greater. Tapered roller bearings with tapered inner and outer ring raceway, tapered roller are arranged in between. All lines of conical surface projection at the same meet the bearing axis. This design makes the wind power bearing are particularly suitable to withstand complex (radial and axial load). Axial load bearing capacity is largely determined by the contact angle; alpha angle is larger, the axial load capacity is higher. Angle by calculating coefficients of e to say; the bigger the E value, the larger the contact angle, the axial load is bigger.
Tapered roller bearings are usually separated type, namely the cone assembly with roller and cage assembly composed of conical outer ring and inner ring can be installed separately (outer ring).
Tapered roller bearings are widely used in cars, rolling mill, mine, metallurgy, plastics machinery industry.
dental bearing are the development trend of China
Since the founding of new China Chinese, tapered roller bearings industry make a spurt of progress has been made in the development of. However, at present, from product development, product quality level and production and manufacturing level, there is a big gap with world leading manufacturer of tapered roller bearings, the majority is in the imitation level, most of the general low-grade tapered roller Zhou Chengzhan. Therefore, in recent years, China has increased efforts in scientific research, obtained certain progress in product level.
At present, the following the development trend of China's circular cone roller bearings industry: increase the scale of production, improve the production investment; increase scientific research strength, strengthen the innovation, especially on the bearing life and reliability as the focus; constantly adjusting the broad product portfolio, enhance the tapered roller bearing structure design and Application technology research, expand the special high precision and high added value of cone roller bearing capacity; focus on the development of speed, accuracy, high reliability, long life, low friction, low vibration, low noise, high tech products bearing.
