FGE12 Slewing Drive for High Torque Rotary Equipment

The FGE12 Slewing Drive is designed for rotary equipment that requires high torque transmission, stable positioning, and dependable operation under substantial axial, radial, and tilting loads. Developed as part of the YOJU FGE/FGA series, this slewing drive combines an enclosed housing, worm gear transmission, sealing protection, and flexible installation options for demanding industrial applications.

The FGE/FGA series is available in a full range of models from 3 to 25 inches, with multiple precision levels available for different equipment requirements. The FGE12 configuration provides a higher load capacity for applications where compact rotary transmission must work under considerable mechanical loads while maintaining controlled movement.

High Torque Capacity for Demanding Applications

The FGE12 Slewing Drive delivers an output torque of up to 7.5 kN·m, making it suitable for equipment that requires substantial rotational force. Its tilting moment torque reaches 54.3 kN·m, while the holding torque is rated at 45 kN·m, providing strong resistance to external moments when the driven structure is stationary or positioned under load.

The drive supports an axial load of up to 475 kN and a radial load of 190 kN. These capabilities make the FGE12 suitable for rotary mechanisms where the drive must accommodate combined loading rather than simply transmit rotational torque.

Hourglass Worm Gear for Greater Contact

The FGE/FGA series uses an hourglass worm gear design to increase the contact area between the worm and gear. More extensive gear engagement can help distribute transmission forces and reduce concentrated loading across individual contact areas.

This design is particularly useful for applications involving frequent rotation and high torque requirements. When properly selected, installed, and lubricated, the larger contact area can contribute to smoother power transmission and longer working life while supporting consistent rotary performance.

Self Locking Gearset for Stable Positioning

The FGE12 features a self-locking gearset designed to help hold the output position when active rotation is not being applied. This characteristic is valuable for equipment where maintaining a fixed angular position is an important part of the operating process.

Applications such as aerial working platforms, solar trackers, welding positioners, and high-accuracy rotating platforms can benefit from controlled holding performance. Actual self-locking behavior depends on the operating conditions, load, installation orientation, and complete mechanical configuration.

Continuous Clockwise and Counterclockwise Rotation

The FGE12 Slewing Drive supports continuous 360° clockwise and counterclockwise rotation, providing flexibility for equipment requiring repeated rotary movement. The bidirectional design allows the same drive configuration to support different movement patterns without restricting rotation to a single direction.

This capability is useful for rotary platforms, positioning equipment, tracking mechanisms, and machinery that needs repeated angular adjustment. Combined with its high torque capacity, it allows engineers to develop compact rotary assemblies for applications with demanding movement requirements.

Precision Options for Accurate Rotary Movement

Rotary equipment does not always require the same positioning accuracy. The FGE/FGA series therefore offers multiple precision levels, with customization available for applications requiring specific performance characteristics.

The FGE12 has a specified backlash of ≤0.17°, providing controlled angular movement for equipment where excessive play could affect positioning performance. Precision requirements should be evaluated together with load conditions, operating speed, duty cycle, and required positioning repeatability.

Enclosed Housing for Outdoor Protection

The FGE12 Slewing Drive uses an enclosed housing to protect the internal transmission components from external contaminants. Shaft sealing and lip seal arrangements help prevent dust and water from entering the drive during operation.

This enclosed construction can reduce contamination-related maintenance requirements, particularly when the drive is installed in outdoor equipment or environments exposed to dust and moisture. Proper installation and routine inspection remain important for maintaining sealing performance throughout the service life.

These values provide a reference for preliminary selection. Final sizing should consider the actual load direction, load distribution, rotation speed, duty cycle, mounting structure, environmental conditions, and required accuracy.

Flexible Installation and Customization

The FGE12 can be configured to accommodate different equipment integration requirements. Metric and British options are available, while installation dimensions and input interfaces can be customized according to the application.

This flexibility is useful for OEM equipment manufacturers and engineering teams that need to integrate a slewing drive into an existing mechanical layout. Custom input interfaces can also simplify compatibility with different motor and drive arrangements.

Rather than selecting a drive solely according to output torque, engineers should evaluate the complete operating envelope. Tilting moment, axial load, radial load, backlash, installation orientation, and required rotation characteristics all influence the appropriate configuration.

Applications of the FGE12 Slewing Drive

The FGE12 Slewing Drive is designed for applications requiring high torque, controlled rotation, and strong load-handling capability. Typical applications include aerial working platforms, high-accuracy rotating platforms, solar trackers, and welding positioners.

For solar tracking equipment, the drive can provide controlled bidirectional rotation for tracking structures. In welding positioners, its high torque and positioning characteristics can support controlled workpiece rotation. Rotary platforms can also benefit from the combination of compact transmission, high load capacity, and customizable precision.
