What is the difference between crossed roller bearings and slewing bearings?
1. Structure:
Crossed roller bearing is a special type of bearing with a divided inner ring and a rotating outer ring.
Slewing bearings are also called slewing bearings. Some people also call them: slewing bearings and slewing bearings. Rotary drive usually consists of worm, slewing bearing, housing, motor and other components.
2. Installation:
The divided inner ring or outer ring of crossed roller bearings is fixed together with the crossed roller collar after the rollers and spacers are installed to prevent separation from each other, so the installation of the crossed roller collar is simple. .
The rollers and isolation blocks of the slewing bearing should be correctly placed. Place the selected cylindrical rollers and circular isolation blocks along the path. When placing adjacent cylindrical rollers, their axes are perpendicular to each other, and the two rollers are separated by an isolation block.
3. Features:
Because the rollers of crossed roller bearings are arranged in a cross, only one set of crossed roller rings can bear loads in all directions. Compared with traditional models, the rigidity is increased by 3 to 4 times.
Since the core component of the slewing bearing adopts a slewing bearing, it can withstand axial force, radial force and overturning moment at the same time.
4. Application scope:
Crossed roller bearings are mainly used in: precision rotary indexing tables for machine tools, vertical and horizontal boring machines, vertical grinders, rotary surface grinders, large gear hobbing machines, gun and radar rotary tables, large radio and optical telescopes, rotating cameras, Steering pivots and continuous casting machines, height-restricted pivot microscope stages, rod center pivots, rotary bogies, welding brackets, rotary assembly jigs, industrial robots, precision rotary tables, medical equipment, measuring instruments, IC manufacturing equipment .
Slewing bearings are mainly used in: truck cranes, railway cranes, port cranes, marine cranes, metallurgical cranes, container cranes, excavators, filling machines, and CT machine standing wave therapy devices, navigation instruments, radar antenna bases , missile launchers, tanks, robots, revolving restaurants, etc.
