Slewing Ring Bearing is a large bearing with special structure that can bear large axial load, radial load and overturning moment and other comprehensive loads at the same time, and integrates various functions such as support, rotation, transmission and fixation. In general, Slewing Ring Bearing itself has mounting holes, lubricating oil and sealing devices, which can meet the different needs of various types of hosts working under various working conditions; on the other hand, Slewing Ring Bearing itself has a compact structure, It is widely used in large-scale rotary devices such as lifting and transportation machinery, excavators, construction machinery, port machinery, wind power generation, medical equipment, radar and missile launchers.

 

Slewing Ring Bearing

 

1. Slewing Ring Bearing structure and classification:

 

Slewing Ring Bearing is usually composed of four major components: inner ring, outer ring, rolling elements, and spacer blocks. Because the core component adopts slewing bearing, it can bear axial force and radial force at the same time. There are many forms, but the structure and composition are basically the same.

 

From left and right are (upper part): 1. Outer ring (with or without teeth) 2. Sealing belt 3. Rolling body (ball or roller) 4. Oil filler

 

From left and right are (lower part): 1. Plug 2. Taper pin 3. Inner ring (with or without teeth) 4. Spacer block or cage 5. Mounting hole (wire hole or smooth hole)

 

Slewing Ring Bearing is mainly divided into single row four-point contact ball type Slewing Ring Bearing, double row ball type Slewing Ring Bearing, single row cross roller type Slewing Ring Bearing, light Slewing Ring Bearing, other series of Slewing Ring Bearing.

 

01 Series Slewing Ring Bearing

 

The single-row four-point contact ball type Slewing Ring Bearing is composed of four parts: inner ring, outer ring, steel ball, and spacer block. The structure is compact and light in weight. The steel ball contacts the arc raceway at four points, and can bear axial force at the same time. , radial force. Construction machinery such as rotary conveyor, welding manipulator, small and medium-sized crane and excavator can be selected.

 

01 Series Slewing Ring Bearing

 

02 Series Slewing Ring Bearing

 

The double-row ball-type Slewing Ring Bearing has three seats, and the steel balls and spacers can be directly discharged into the upper and lower raceways. According to the stress conditions, the upper and lower rows of steel balls with different diameters are arranged. This kind of open assembly is very convenient, and the bearing angle of the upper and lower arc raceways is 90°, which can bear a large axial force and tipping moment. When the radial force is greater than 0.1 times the axial force, the raceway must be specially designed. The axial and radial dimensions of the double-row reducing ball slewing bearing are relatively large and the structure is tight. It is especially suitable for loading and unloading machinery such as tower cranes and truck cranes that require medium or larger diameters.

 

02 Series Slewing Ring Bearing

 

Series Slewing Ring Bearing

 

Single-row cross-roller type Slewing Ring Bearing, consisting of two races, is compact in structure, light in weight, high in manufacturing precision, small in assembly clearance, and requires high installation accuracy. The axial force, tipping moment and large radial force are widely used in lifting and transportation, construction machinery and military products.

 

Series Slewing Ring Bearing

 

Three-row roller Slewing Ring Bearing has three races with separate upper and lower and radial raceways, so that the load of each row of rollers can be determined exactly. It can bear various loads at the same time, and is the one with the largest bearing capacity among the four products. The shaft and radial dimensions are large and the structure is firm. It is especially suitable for heavy machinery requiring large diameters, such as bucket wheel excavators, wheel Cranes, marine cranes, port cranes, molten steel running table and large tonnage truck cranes and other machinery.

 

Light Series Slewing Ring Bearing

 

Lightweight Slewing Ring Bearing has the same structural form as ordinary slewing bearing, light weight and flexible rotation. Widely used in food machinery, filling machinery, environmental protection machinery and other fields.

 

Light Series Slewing Ring Bearing

 

HS Series Slewing Ring Bearing

 

The single-row four-point contact ball type Slewing Ring Bearing consists of two races, with a compact structure and four-point contact between the steel ball and the arc raceway. Mainly used in truck cranes, tower cranes, excavators, pile drivers, engineering vehicles, radar scanning equipment and other machines that are subjected to overturning moment, vertical axial force, and horizontal inclination force.

HJ Series Slewing Ring Bearing

 

The single-row cross-roller type Slewing Ring Bearing consists of two races, with compact structure, high manufacturing precision, small assembly clearance, and high requirements for installation accuracy. Overturning moment and large radial force are widely used in transportation, construction machinery and military products.

2. Slewing Ring Bearing Uses:

 

Its function is to connect the upper and lower parts of the machine together, and at the same time, it is used to support the weight of the upper part and the load generated when the machine works, and to make the upper part of the machine rotate relative to the lower part (or the lower part rotates relative to the upper part).

 

3. Slewing Ring Bearing Applications

 

Construction machinery is where Slewing Ring Bearing is applied and applied, such as earthmoving machinery, excavators, dismantling machines, stackers and reclaimers, graders, road rollers, dynamic compactors, rock drilling machinery, roadheaders, etc. Others include: concrete machinery, feeding machinery, lifting machinery, foundation treatment machinery, engineering ships, light industrial machinery, etc.

 

In addition to various construction machinery, the application range of Slewing Ring Bearing has gradually expanded, and equipment platforms such as port equipment, metallurgical equipment, drilling platforms and other equipment platforms have begun to use Slewing Ring Bearing instead of original bearings on a large scale.

4. Slewing Ring Bearing Installation Features:

 

Before the installation of Slewing Ring Bearing, the installation surface of the host should be checked first. It is required that the support should have sufficient strength, the connecting surface should be machined, and the surface should be smooth and free of debris and burrs. For those that cannot be machined to achieve the required flatness, special plastics with high injection strength can be used as fillers to ensure the accuracy of the installation plane and to reduce vibration.

 

The ferrule of Slewing Ring Bearing has a quenched soft belt area, which is marked with "S" on the end face of the ferrule. When installing, the position of the soft belt should be placed in the non-load area or the non-regular load area (the plug hole is always located in the soft belt).

 

When installing Slewing Ring Bearing, locate radially, tighten mounting bolts crosswise, and check bearing rotation. There should be sufficient pre-tightening force when tightening the bolt, and the pre-tightening force should be 70% of the yield limit of the bolt material. Mounting bolts should be equipped with quenched and tempered flat washers and spring washers are strictly prohibited.
