1. Different concepts
1. Slewing bearing
Slewing bearing is a new type of mechanical parts, which is composed of inner and outer rings and rolling bodies. Slewing bearing is a large bearing that can bear comprehensive loads, and can bear large axial and radial loads and overturning moments at the same time.
2. Rotary table bearing
Rotary table bearing is a kind of large bearing with special structure, which can bear large comprehensive loads such as axial load, radial load and overturning moment at the same time, and has multiple functions such as support, rotation, transmission and fixation.
second, the structure is different
1. slewing bearing
slewing drive is usually composed of worm, slewing bearing, shell, motor and other parts. Because 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.
2. Rotary table bearing
Rotary table bearing is usually composed of four parts: inner ring, outer ring, rolling body and isolation block. Because the core component adopts slewing bearing, it can bear axial force and radial force at the same time. There are many forms, but the structural composition is basically the same.
3. Different applications
1. Slewing bearing
Slewing bearing is widely used. Construction machinery is the first and most widely used place of slewing bearing, such as earth-moving machinery, excavators, disintegrators, reclaimers, graders, rollers, dynamic compactors, rock drilling machines, roadheader and so on.
There are other concrete machinery: concrete pump truck, concrete mixing and placing boom integrated machine, belt cloth feeder, disc feeder, sand mixer; Lifting machinery: wheeled crane, crawler crane, portal crane, tower crane, fork crane, crane with crane and gantry crane.
foundation treatment machinery: impact reverse circulation drilling rig, rotary drilling rig, impact rotary drilling rig, rotary drilling rig, reverse circulation rotary drilling rig, positive circulation rotary drilling rig, long spiral engineering drilling rig, diving engineering drilling rig, static pile driver and pile driver.
engineering ship: dredger; Special vehicles: bridge inspection vehicles, fire engines, window cleaners, flat beam carriers, aerial work vehicles and self-propelled aerial work platforms; Light industrial machinery: beverage machinery, bottle blowing machine, packaging machinery, filling machine, rotary bottle sorting machine, injection molding machine; Marine crane: floating crane.
2. Rotary table bearings
Rotary table bearings are widely used. Construction machinery is the first and most widely used place for rotary table bearings, such as earth-moving machinery, excavators, disintegrators, stacker-reclaimers, graders, road rollers, dynamic compactors, rock drilling machines and roadheader.
