What do you know about slewing rings?

The slewing rings are widely used in large swivel equipment such as hoists, mining machinery, construction machinery, port machinery, ship machinery and equipment, as well as in high precision radar machinery and rocket launchers. At the same time, it can also design, develop and produce various slewing rings with special structure according to users' specific requirements.

What are the industrial applications of slewing rings?

1.Special vehicles: bridge inspection vehicles, fire fighting vehicles, window cleaning machines, flat beam transport vehicles, aerial work platforms, self-propelled aerial work platforms;

2.Light industrial machinery: beverage machines, blow molding machines, packaging machines, filling machines, rotating bottle racks, injection molding machines;

3. Ship cranes: floating cranes. In addition to various construction machinery, the application spectrum of slewing rings has gradually expanded, and equipment platforms such as port facilities, metallurgical facilities, drilling platforms, etc. have begun to use large-scale roller bearings instead of original bearings.

4. Port equipment: port cranes, reach stackers;

5.New energy equipment: wind power generation equipment, solar power generation equipment;

6.Metallurgical equipment: metallurgical crane, ladle turntable, steel gripper, sludge cannon, oxygen blower, etc.

What is the design difference between rotary table bearings and slewing rings?

Other structure

1. slewing rings

Slewing drive usually consists of screw, slewing bearing, shell, motor and other components. Since the core component adopts a slewing ring, it can bear axial force, radial force and tilting moment at the same time. There are many forms, but the structural structure is basically the same.

2. Rotary table bearings

Rotary table bearings usually consist of four parts: inner ring, outer ring, rolling element and insulation block. Since the core component adopts a slewing ring, it can carry axial force and radial force at the same time. There are many forms, but the structural structure is basically the same.

What are the characteristics of slewing rings?

slewing rings generally have mounting holes, inner or outer gears, lubricating oil holes and sealing devices, so the design of the main motor is compact, easy to guide and easy to maintain. The slewing rings include four-point ball bearings without gears, external and internal gears, double row angular contact ball bearings, crossed cylindrical roller bearings, crossed tapered roller bearings and three row composite cylindrical roller bearings. Series in which the four-point ball bearing has high static bearing capacity, the crossed cylindrical roller has high dynamic bearing capacity, and the pre-interference of the crossed tapered roller bearing can cause the bearing to have greater support rigidity and rotation accuracy, The three row cylindrical roller combination bearing leads to the height of the bearing due to the improvement of the bearing capacity, and different forces are carried by different raceways, so that with the same force the bearing diameter can be greatly reduced, the main motor is more compact. A slewing ring with high load capacity.
