Straight Tooth Slewing Drive: Reliable and Efficient Rotary Motion Solution

The straight tooth slewing drive, also known as a gear-type slewing drive, is a rotary reduction device that combines components such as rotary bearings, gears, shells, adapter flanges, support bearings, seals, and more. Designed for high performance, the slewing drive can withstand axial force, radial force, and overturning torque simultaneously, while providing a reduction ratio for controlled motion. This system is widely used in various industries for its compact design and reliability.

Key Characteristics of Straight Tooth Slewing Drive

  1. Corrosion Resistance and Aesthetic Design
    The surface of components like the slewing drive housing and flanges is treated with phosphating or spray molding, providing both corrosion resistance and an appealing finish.

  2. Durable Gear and Gear Ring
    The gears and gear ring undergo a tooth quenching process, improving tooth bearing capacity, wear resistance, and extending the product’s service life.

  3. Reliable Bearing Support
    The gears are supported by bearings at both ends, ensuring smooth rotation and high reliability, preventing damage to the gearbox shaft or motor shaft.

  4. Customizable Adapter Flange
    Adapter flanges are customized based on customer needs, ensuring compatibility with various installation environments and simplifying integration.

  5. Compact and Space-Saving Design
    The slewing drive features a compact design, helping customers save installation space and facilitating the design of lightweight machines for easier installation.

  6. High-Speed Rotation with Four-Point Contact Ball Bearings
    The slewing bearing is a four-point contact ball type, capable of withstanding axial, radial loads, and overturning torque, ensuring high rotational speeds.

  7. Strong and Durable Shell
    The shell is made from QT450-10 casting, offering excellent strength, wear resistance, and durability with minimal processing deformation.

  8. Sealed for Protection
    Both the slewing bearing and shell are sealed with NBR rubber, providing dust and splash protection with an IP65 rating, ensuring long-lasting performance even in harsh environments.

  9. Fully Wrapped Design for Reduced Maintenance
    The slewing drive adopts a fully wrapped design, reducing grease contamination and loss, which in turn lowers maintenance frequency and operational costs.

Straight Tooth Slewing Drive Sealing

The sealing of the straight tooth slewing drive uses NBR oil-resistant nitrile rubber seals. The sealing ensures that the rotary bearing’s channel, as well as the connection between the bearing and shell, is sealed off, preventing dust and water ingress. This effectively reduces maintenance requirements and enhances the overall reliability of the system.

Support Bearing in Straight Tooth Slewing Drive

The support bearing is crucial in supporting the rotation of the gears. Depending on operational conditions, a variety of universal bearings are selected, including:

  • Angular contact ball bearings

  • Tapered roller bearings

  • Cylindrical roller bearings

  • Deep groove ball bearings

The selection is based on performance parameters such as load and speed, ensuring optimal operation in diverse applications.

Adapter Flange for Straight Tooth Slewing Drive

The adapter flange plays a dual role in the slewing drive. It not only fixes the gear to the housing but also serves as the input connection point between the user’s reducer or motor and the slewing drive. Adapter flanges are designed to match the output size of the reducer or motor, ensuring a secure and stable connection. Customizing the adapter flange ensures compatibility with specific equipment and solves challenges such as flange interference or bolt arrangement issues during installation.

Applications of Straight Tooth Slewing Drive

The straight tooth slewing drive is highly versatile and finds use in many industries, including:

  • Industrial robots

  • Machine tool turntables

  • Cranes and truck-mounted cranes

  • Automated production lines

  • Radar cars

  • Displacement machines

  • Flexible bending machines

  • Grass-grabbing machines

  • Solar panel snow plows

  • Forestry machinery

  • Agricultural machinery
