What is joint bearing?

wallpapers Tech 2020-05-19
The spherical plain bearing is a spherical sliding bearing. Its sliding contact surface is an inner spherical surface and an outer spherical surface. It can rotate and swing at any angle during movement. It uses a variety of individual processes such as surface phosphating, frying, padding, spraying methods. The spherical plain bearing has the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, and excellent lubrication.
The structure of the spherical plain bearing is more straightforward than that of the rolling bearing, which is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. Spherical plain bearings are used in low-speed oscillating motion (ie, angular motion). Since the sliding surface is spherical, tilting movements (that is, self-aligning movements) can also be performed within a specific angle range. When the degree is large, it can still work typically.
Characteristics of plain spherical bearings
Spherical plain bearings can withstand larger loads. According to its different types and structure, it can bear radial and axial load or a combined load of radial and axial. The bearing can produce self-lubrication during operation since the outer spherical surface of the inner ring is covered with composite material. Usually used in low-speed swing motion and low-speed rotation, it can also be used for tilting motion within a specific angle range. It can still work typically when the support shaft and the shaft shell hole are not centered. Self-lubricating spherical bearings are used in water conservancy, professional machinery, and other industries.
