There are two common noises of slewing ring bearing: dust noise and scars noise. The solutions are as follows:
The slewing bearing is a new type of mechanical parts, which consists of inner and outer rings, rolling elements and so on. The slewing ring bearing is a large bearing that can withstand comprehensive loads. It can simultaneously bear large axial and radial loads and overturning moments.
Slewing bearings are also called slewing ring bearings. Some people also call it: turntable bearing, slewing ring. The English names are: slewing bearing, slewing ring bearing, turntable bearing, slewing ring. Slewing bearings are widely used in real industry and are called "joints of machines". It is an important transmission component necessary for a machine that requires relative rotational movement between two objects and simultaneously bears axial force, radial force, and tilting moment. With the rapid development of the machinery industry, slewing bearings have been widely used in marine equipment, engineering machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.
China slewing ring bearing are widely used. Construction 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 machines, road headers and so on.
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; Lifting machinery: wheeled cranes, crawler cranes, portal cranes, tower cranes, fork cranes, cranes, gantry cranes; Ground 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, submersible engineering drilling rig, static pile press, pile driver; Engineering ships: dredger; Special vehicles: bridge inspection vehicles, fire trucks, window cleaners, flat beam transport vehicles, aerial work vehicles, self-propelled aerial work platforms; Light industry machinery: beverage machinery, bottle blowing machine, packaging machinery, filling machine, rotary bottle unscrambler, injection molding machine; ship crane: floating crane.
