Spherical bearings can be classified into different types based on their structure and usage scenarios, mainly including the following types:
1. Radial spherical bearing: This type of bearing can withstand radial loads from various directions, usually composed of inner ring, outer ring, steel ball, and cage. Its characteristics include simple structure, convenient installation, high load-bearing capacity, and low friction.
2. Radial axial composite spherical bearing: This type of bearing can withstand both radial and axial loads, usually composed of inner ring, outer ring, steel ball, and cage. Its characteristics include high load-bearing capacity and suitability for situations subjected to radial and axial bidirectional loads.
3. Self aligning spherical bearings: This type of bearing has an automatic centering function, which can automatically adjust the relative positions of the inner and outer rings of the bearing during installation and operation to adapt to installation errors and displacement of the bearing seat. Its characteristics include good centering performance, suitability for high-speed operation and high vibration situations.
4. Bidirectional angular contact spherical bearing: This type of bearing can withstand axial loads from two directions simultaneously, usually composed of inner ring, outer ring, steel ball, and cage. Its characteristics include high load-bearing capacity, high stiffness, and suitability for situations that require high precision and stiffness.
The characteristics of spherical bearings mainly include the following aspects:
-High load-bearing capacity: Spherical bearings can withstand radial and axial loads from different directions and have a large load-bearing capacity.
-Low friction: Due to the use of rolling friction in spherical bearings, the friction force is relatively small, which can reduce energy loss and wear.
-High precision: Spherical bearings have high precision and geometric precision, which can meet the requirements of high-precision equipment and precision machining.
-Good self centering performance: Self centering spherical bearings have good self centering function, which can automatically adjust the relative positions of the inner and outer rings of the bearing, adapt to installation errors and displacement of the bearing seat.
-Tolerance to vibration and impact: Spherical bearings can absorb and mitigate external vibrations and impacts, protecting mechanical equipment from damage.
Choosing the appropriate type of spherical bearing based on different job requirements and application scenarios is of great significance, as it can effectively protect mechanical equipment and extend its service life.
