Some introduction to tapered roller bearings
Bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotary accuracy. According to the different frictional properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings its radial size, vibration and noise are larger, and the price is also higher. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling body and cage. According to the shape of the rolling body, rolling bearings are divided into two categories: ball bearings and roller bearings.
The bearings are suitable for the lubrication of rolling bearings and sliding bearings and other friction parts of general mechanical equipment, and the operating temperature is: -20°℃~180°℃. They are widely used in machinery and equipment, water and electricity conservancy, engineering, railroad, automobile, steel, electric power, textile, packaging, medical, metallurgy, mining, petroleum, electric power, paper making, electronic computer, motor, sports equipment, office equipment, instrumentation, automobile motor, precision instruments, light industry textile machinery and other fields.
Tapered roller bearings belong to the separation type bearings, bearing the inner and outer ring have tapered raceway. These bearings are divided into single row, double row and four row tapered roller bearings and other different structure types according to the number of rollers installed. Single row tapered roller bearings can bear radial load and single direction axial load. When bearing radial load, will produce an axial force, so need another can bear the opposite direction of the axial force of the bearing to balance.
Single tapered roller bearing bearing axial load capacity depends on the contact angle, that is, the outer ring raceway angle, the larger the angle, the greater the axial load capacity. Tapered roller bearings in the most amount of single-row tapered roller bearings. In the front wheel hub of the car, with a small size of double row tapered roller bearings. Four-row tapered roller bearings are used in large cold and hot rolling mills and other heavy machinery.
Tapered roller bearings are mainly used to bear radial load mainly radial and axial combined load. Compared with angular contact ball bearings, the load carrying capacity is large, and the limit speed is low. Tapered roller bearings can withstand the axial load in one direction, can limit the axial displacement of the shaft or shell in one direction. Tapered roller bearings are usually separated type, that is, the inner ring with roller and cage assembly composed of tapered inner ring assembly can be installed separately with the tapered outer ring (outer ring). Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
Linqing Jiyi Bearing Co., Ltd. always adheres to the people-oriented principle, focuses on absorbing and cultivating technical and management talents, and has accumulated strong intellectual capital.
