Do you understand the internal structure and application of slewing bearings?
Slewing bearings are also called turntable bearings. It is a new type of mechanical component that has gradually emerged around the world in the past 40 years. It consists of inner and outer rings, rolling elements, etc.
The slewing bearing is a large bearing that can withstand comprehensive loads and can withstand large axial, radial loads and overturning moments at the same time.
basic structure
The slewing bearing is usually composed of a worm, a slewing bearing, a housing, a motor and other components. Since the core component adopts slewing bearing, it can bear axial force, radial force and overturning moment at the same time. There are many forms, but the structural composition is basically the same.
Basic structure of slewing bearing
From left to right they are (upper part):
1. Outer ring (with teeth or without teeth)
2.Sealing tape
3. Rolling elements (rolling balls or rollers)
4. Fill the gas tank
From left to right they are (lower part):
1. clog
2. Blocking pin
3. Inner ring (with teeth or without teeth)
4.Isolation block or cage
5. Installation holes (wire holes or light holes)
Slewing bearing application
Slewing bearings are widely used. Engineering machinery is the first and most widely used place for slewing bearings, such as earthmoving machinery, excavators, dismantling machines, stackers and reclaimers, graders, road rollers, dynamic compactors, rock drilling machinery, tunnel boring machines, etc.
Others include: concrete machinery: concrete pump truck, concrete mixing and placing boom integrated machine, belt placing machine.
Feeding machinery: disc feeder, sand mixer.
Hoisting machinery: wheeled cranes, crawler cranes, gantry cranes, tower cranes, fork cranes, accompanying cranes, gantry cranes.
Foundation treatment machinery: impact reverse circulation drilling rig, rotary drilling rig, impact rotary drilling rig, rotary drilling rig, reverse circulation rotary drilling rig, forward circulation rotary drilling rig, long spiral engineering drilling rig, submersible engineering drilling rig, static pressure pile driver, pile driver.
Engineering ships: dredgers.
Special vehicles: bridge inspection vehicles, fire trucks, window cleaning machines, flatbed beam carriers, aerial work vehicles, self-propelled aerial work platforms.
Light industrial machinery: beverage machinery, bottle blowing machines, packaging machinery, filling machines, rotary bottle unscramblers, injection molding machines, marine cranes.
