What is the difference between a slewing ring and a slewing bearing?

One, the concept is different

1. Slewing bearing

The slewing ring is a new type of mechanical parts, it is composed of inner and outer rings, rolling bodies, etc. The slewing ring is a large-scale bearing that can accept generalized loads, and can accept large axial and radial loads and overturning moments together.

2. Turntable bearings

The slewing bearing is a large bearing with a special structure that can accept large axial loads, radial loads and overturning moments and other generalized loads, and integrates multiple functions such as support, rotation, transmission, and fixation.

Two, the structure is different

1. Slewing bearing

The slewing drive is generally composed of worms, slewing bearings, housings, motors and other components. Because the core components are slewing bearings, they can receive axial force, radial force, and tilting moment together. There are many forms, but the structure and composition are basically the same.

2. Turntable bearings

Slewing bearings are generally composed of four parts: inner ring, outer ring, rolling body, and blocking block. Because the core components are slewing bearings, they can receive axial and radial forces together. There are many forms, but the structure and composition are basically the same.

Three, use different

1. Slewing bearing

Slewing bearings are widely used, and construction machinery is the place where slewing bearings are used and widely used, such as earthmoving machinery, excavators, dismantling machines, stackers and reclaimers, graders, road rollers, dynamic compactors, rock drilling machines, roadheaders, etc.

There are other concrete machinery: concrete pump truck, concrete mixing and placing boom integrated machine, belt-type placing machine. Feeding machinery: disc feeder, sand mixer; hoisting machinery: wheel crane, crawler crane, door Block cranes, tower cranes, fork cranes, cranes, gantry cranes.

Ground treatment machinery: impact reverse circulation drilling rigs, rotary drilling rigs, impact rotary drilling rigs, rotary drilling rigs, reverse circulation rotary drilling rigs, forward circulation rotary drilling rigs, long spiral engineering drilling rigs, submersible engineering drilling rigs, static pile presses, pile drivers .

Engineering ships: dredgers; special vehicles: bridge inspection vehicles, fire trucks, window cleaners, flat beam transport vehicles, aerial work vehicles, self-propelled aerial work channels; light industrial machinery: beverage machinery, bottle blowing machines, packaging machinery, Filling machine, rotary bottle unscrambler, injection molding machine; marine crane: floating crane.

2. Turntable bearings

Slewing bearings are widely used, and construction machinery is the place where the slewing bearings are first used and are widely used, such as earthmoving machinery, excavators, dismantling machines, stackers and reclaimers, graders, road rollers, dynamic compactors, rock drilling machines, roadheaders, etc.
