What is a joint bearing?

wallpapers Tech 2020-05-18
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 special processes such as surface phosphating, frying, padding, spraying Method. The spherical plain bearing has the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning and good lubrication.
The structure of the spherical plain bearing is simpler 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 generally used for low-speed oscillating movements (that is, angular movements). Since the sliding surface is spherical, tilting movements (that is, self-aligning movements) can also be performed within a certain angle range. When the degree is large, it can still work normally.
Characteristics of spherical plain bearings
Spherical plain bearings can withstand larger loads. According to its different types and structure, it can bear radial load, axial load or combined load of radial and axial. Since the outer spherical surface of the inner ring is covered with composite material, the bearing can produce self-lubrication during operation. It is generally used for low-speed swing movement and low-speed rotation, and can also be used for tilting movement within a certain angle range. It can still work normally when the support shaft and the shaft shell hole are not centered. Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries.
