slewing bearingIt is a new type of mechanical component,. Composed of inner and outer rings and rolling elements.. It is a large bearing that can withstand comprehensive load, and can withstand large axial and radial loads and overturning moments at the same time.

Rotating bearings are also called slewing bearings,. It is also called: rotary bearings and slewing bearings. English names are: sleeping bear, sleeping ring bear, turntable bear, sleeping ring. Rotary bearings are widely used in practical industry.. It is called the "joint of the machine" and is the relative rotational movement between two objects required by the machine., At the same time to bear the axial force, radial force and tilting moment of the important transmission components. With the rapid development of the machinery industry, slewing bearings have been widely used in marine equipment, construction machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.

Slewing bearing;Basic structure

Rotary drive is usually composed of worm, rotary bearing, housing, motor and other components. As the core components of the slewing bearing, can bear the axial force, radial force and tilting moment. There are many forms, but the structural composition is basically the same.

From left to right are (upper):1. Outer ring (with or without teeth) 2. Sealing tape 3. Rolling body (ball or roller) 4. The oil filler port is from left to right (lower part):1. Blocking 2. Blocking pin 3. Inner ring (toothed or untoothed) 4. Isolation block or cage 5.. Mounting hole (wire hole or light hole).

slewing bearing; Application areas

Construction machinery

Slewing bearings are widely used,. Construction machinery is the earliest and most widely used place for slewing bearings, such as earth-moving machinery, excavators, crushers, stacker-reclaimers, graders, road rollers, power compactors, rock drills, roadheaders, etc. Others are concrete machinery: concrete pump truck, concrete mixing and distribution rod integrated machine, belt feeder feeding machinery: disc feeder, sand mixer;. Hoisting machinery: wheel crane, crawler crane, gantry crane, tower crane, fork crane, accompanying crane, 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, submersible engineering drilling rig, static pressure pile driver, pile driver; engineering ship: dredger; special vehicles: bridge inspection vehicle, fire truck, window cleaning machine, flat beam transport vehicle, aerial work vehicle, self-propelled aerial work platform; Light industrial machinery: beverage machinery, bottle blowing machine, packaging machinery, filling machine, rotary bottle dividing machine, injection molding machine; Marine crane: floating crane..
