What are the application fields of slewing bearings?

What are the application fields of slewing bearings? Slewing ring bearings have unique load-bearing characteristics and are usually used in hoisting machinery, excavators, slewing tables, wind power generators, telescopes and tank turrets. Through the improvement of processing methods and the renewal of design concepts, slewing bearings can be applied to occasions with smaller dimensions, more complex structures and more precision.

In the machine tool industry, the slewing bearing of the standard structure adopts high-precision grades and applies preload to eliminate clearance and reduce vibration. The radial runout and diameter tolerance range of the bearing are within the controllable design range, the structure is compact, the cross-sectional size is small, and the diameter size can be as small as 50 mm, which prompts designers to reconsider the traditional bearing configuration.

Slewing bearings are used in crane bearings, crane bearings, bucket wheel bearings, marine crane bearings, shield machine bearings, ladle large bearings, and other turntable equipment bearings subject to radial, axial and moment loads.

Slewing bearings are widely used. Construction machinery is the initial application field of slewing bearings and is also widely used, such as earthmoving machinery, excavators, dismantling machines, stackers and reclaimers, graders, road rollers, dynamic compaction machines, rock drilling machinery, roadheaders, etc. .

• Concrete machinery: concrete pump truck, concrete mixing and distributing boom integrated machine, belt distributing machine
• Feeding machinery: disc feeder, sand mixer
• Hoisting 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, diving engineering drilling rig, static pressure pile machine, pile driver
• Engineering ships: dredgers, sand dredgers.
• Special vehicles: bridge inspection vehicles, fire trucks, window cleaning machines, flat beam transport vehicles, aerial work vehicles, self-propelled aerial work platforms

In addition to various construction machinery, the scope of application of slewing bearings has gradually expanded. At present, equipment platforms such as port equipment, metallurgical equipment, and drilling platforms have begun to use slewing bearings to replace original bearings on a large scale.

• The use of slewing ring bearings in wind power, wind turbine bearings generally include: yaw, pitch, drive train and other bearings.
• The use of slewing ring bearings in the field of solar energy. Tracking solar panels are a very good solution to increase energy, and the slewing ring has a compact design layout, which is the best choice for solar power generation equipment. The use of slewing ring bearings can be seen in solar farms in various regions of the world exist.
• Slewing ring bearings are used in medical equipment to develop a series of high-precision, low-noise, and long-life medical equipment using slewing bearings, and slewing bearings have been widely used in the production of large-scale medical equipment such as gamma knife and CT machines. .
• Metallurgical equipment: metallurgical crane, ladle turret, steel grabbing machine, mud cannon, oxygen blowing device
• Amusement equipment: Ferris wheel, etc.
• Airport equipment: airport refueling machine, luggage cart
• Equipment: radar, tank, warship, etc.
• Robots: palletizing robots, welding robots, manipulators
• Parking equipment: tower garage
• Light industry machinery: beverage machinery, bottle blowing machine, packaging machinery, filling machine, rotary bottle unscrambler, injection molding machine, kitchen equipment, numerical control equipment (NC vertical lathe turntable, quenching machine turntable), brick machine, etc.

Slewing bearings are widely used not only in the industrial field, but also in our daily life. It can be said that it is closely related to our life.
