Overview of Axial spherical roller bearing

wallpapers News 2021-03-01
Axial spherical roller bearings also have a shaft ring and a seat ring, the bearing seat on the shaft is pressed against the shaft ring, and the seal ring is installed when installing --- roller ---- shaft ring ----- the bearing seat of the shaft. Thrust spherical roller bearings are mainly used in petroleum drilling rigs, iron and steel machinery, hydroelectric generators, vertical motors, propeller shafts for ships, tower cranes, extruders, etc. The axial load capacity is large, while bearing the axial load, it can also bear a certain radial load. The spherical rollers of thrust spherical roller bearings are arranged obliquely, and the raceway surface of the raceway is spherical, which has self-aligning performance, so it can allow some tilting of the shaft. It can be used in extremely heavy loads, and the allowed speed is higher. Oil lubrication is generally used during use.
 
Thrust spherical roller bearings are separate bearings. The load action line forms a certain angle with the bearing axis, and the axial load capacity is large. While bearing the axial load, it can also bear a certain radial load. The spherical rollers of this type of bearings are arranged at an angle, and the raceway surface of the race is spherical, which has the self-aligning performance, so it can allow some tilting of the shaft. It can be used in extremely heavy loads, and the allowed speed is higher. Oil lubrication is generally used during use. Rolling bearings can be divided into radial bearings (mainly bearing radial loads), thrust bearings (only bearing axial loads), and radial thrust bearings (can be Understand both radial and axial loads). Radial thrust ball bearings, bearings of this structure, can withstand radial loads and axial loads in one direction. Find a contact angle of 15 degrees, 25 degrees, and 30 degrees with the inner and outer rings to obtain 40 degrees. The greater the contact angle, the greater the axial load-bearing capacity. The smaller the contact angle, the more conducive to high-speed rotation. Usually, the two bearings are opposed, and the internal clearance is adjusted before use.
