Product Description

20 ton and 50 ton truck crane slewing ring bearing with external gear 1752*1495*68mm RKS.062.25.1644
 

Product Description

1. Overview & Product Definition

The RKS.062 series is a specialized Four-Point Contact Ball Bearing featuring integral internal gearing on its inner ring. This design ingeniously combines a high-performance slewing bearing with a built-in gear mechanism. It is engineered to provide a compact, robust, and highly efficient solution for applications that require the support of complex loads while transmitting drive torque through an internally meshing pinion.

2. Key Design Features

• Four-Point Contact Design: At the heart of the bearing is its optimized raceway geometry. Each ball makes contact with the inner and outer rings at four distinct points. This singular row design is exceptionally capable of accommodating combined loads-including axial forces, radial loads, and tilting moments-simultaneously.

• Integral Internal Spur Gear: The defining feature of the RKS.062 series is the precision-machined internal spur gear on the inner ring. This configuration allows a centrally located pinion to drive the system from within the bearing's diameter, offering distinct mechanical advantages.

• High-Grade Bearing Steel: Manufactured from vacuum-degassed, high-carbon chromium steel, these bearings provide a high load-carrying capacity, exceptional durability, and superior resistance to wear.

• Robust Construction: Designed for high static and dynamic load ratings, ensuring reliability in heavy-duty applications.

• Precision Engineering: Both the bearing components and the internal gear teeth are produced to exacting tolerances, ensuring smooth operation, precise positioning, and efficient power transmission.

3. Primary Advantages & Benefits

• Compact Drive Integration: The internal gear design allows the drive pinion to be housed within the envelope of the bearing, resulting in a more compact and space-saving overall assembly compared to external gear designs.

• Protected Gear Mechanism: The internal gear teeth are partially shielded by the bearing structure, offering a degree of protection from direct exposure to external contaminants and potential damage.

• Favorable Meshing Conditions: Internal gear and pinion meshing often allows for more teeth in contact simultaneously, which can lead to smoother operation, higher torque transmission capacity, and reduced wear.

• High Load Versatility: The four-point contact design provides unmatched flexibility in handling complex and fluctuating load combinations with a single bearing.

• Simplified System Design: Integrating the bearing and gear reduces part count, simplifies the surrounding structure, and streamlines the manufacturing and assembly process.

4. Typical Applications

The RKS.062 series is ideally suited for applications where a compact drive solution and protected gearing are paramount:

• Slewing Drives and Rotary Actuators: A fundamental component in compact slewing drives for construction, mining, and solar tracking equipment.

• Turntables and Indexing Platforms: Used in manufacturing, assembly lines, and material handling turntables.

• Robotics: Found in the base and major joints of industrial robots where a compact rotational unit is required.

• Radar and Antenna Pedestals: Provides precise rotation and stability for communication and surveillance systems.

• Wind Turbine Yaw and Pitch Systems (in smaller-scale applications).

• Medical Imaging Equipment: Such as MRI and CT scanners, where smooth, precise, and reliable rotation is critical.

5. Technical Specifications (General)

• Bearing Type: Four-Point Contact Ball Bearing

• Gearing: Internal Spur Gear on the inner ring.

• Size Range: The RKS.062 series is available in a range of standard sizes with specific bore diameters, gear modules, and cross-sections. (For precise dimensions, refer to the official RKS.062 catalog).

• Load Capacity: Engineered to support high axial, radial, and moment loads. Exact values for dynamic and static load ratings are specified in the technical data sheets.

• Lubrication: Requires periodic re-lubrication via standard grease fittings. The appropriate lubricant depends on operational speed, temperature, and environmental conditions.

• Mounting: Typically secured via threaded holes in the bearing rings.

6. Selection and Mounting Considerations

Selecting the correct RKS.062 bearing requires a thorough analysis of several factors:

• Load Calculation: A precise analysis of all applied axial, radial, and moment loads is essential for correct bearing selection.

• Gear Drive Design: Careful calculation of the mating pinion, gear mesh alignment, backlash, and transmitted torque is crucial for optimal performance and longevity.

• Operating Environment: Consider the need for sealing to protect the gear mesh and bearing raceways from contaminants like dust, moisture, or chemicals.

• Structural Rigidity: The housing and supporting structures must be designed to be rigid enough to prevent deformation under load, which could misalign the gear mesh and reduce bearing life.

• Speed and Lubrication: Suitable for slow to moderate rotational speeds. A proper lubrication regimen is vital for the health of both the bearing and the gear teeth.
