FGE12 Slewing Drive

Description

The FGE12 Slewing Drive is an enclosed rotary drive designed for applications requiring continuous 360° rotation, high load capacity, reliable positioning, and protection against demanding operating conditions. As part of the YOJU FGE/FGA series, it combines a compact enclosed housing with an hour-glass worm gear design to provide efficient power transmission, strong load handling, and extended service life.

With sealing protection around the drive housing, the FGE12 slewing drive helps prevent dust and water from entering the internal gearing, reducing maintenance requirements during long-term operation. The series is available in models from 3 to 25 inches, with different precision levels and installation configurations available for specific equipment requirements.

Enclosed Design for Reduced Maintenance

The enclosed housing of the FGE12 slewing drive provides additional protection for the internal gear components against external contaminants. Shaft sealing and lip seal structures help limit the entry of dust and moisture, making the drive suitable for outdoor machinery and equipment exposed to challenging working environments.

This enclosed configuration also reduces the need for frequent maintenance, while helping maintain stable transmission performance over extended operating periods.

Hour-Glass Worm Gear for Higher Load Capacity

The FGE series uses an hour-glass worm gear that increases the contact area between the worm and gear. More gear contact helps distribute the transmitted load across the gearing, supporting smooth rotation and improving durability under demanding operating conditions.

For applications involving frequent rotation, positioning, or considerable external loads, this gear configuration provides a practical combination of torque transmission and service life.

Continuous 360° Rotation and Self-Locking

The FGE12 slewing drive supports continuous 360° clockwise and counterclockwise rotation, allowing equipment to achieve flexible rotary movement without a predefined rotation limit. Its self-locking gearset can help maintain the required position when external forces are applied, which is useful for equipment requiring stable positioning.

The drive can also be configured with different accuracy levels to meet applications where controlled positioning and reduced backlash are important.

Flexible Configuration Options

The FGE/FGA series can be supplied with metric or British configurations according to equipment requirements. Installation dimensions and input interfaces can also be customized for integration with different drive motors, mounting structures, and rotary machinery.

Multiple precision levels are available, while customized specifications can be developed when standard configurations do not match the required equipment design.

Applications of FGE12 Slewing Drive

The FGE12 slewing drive is suitable for equipment that requires controlled rotary motion, high load resistance, and reliable positioning. Typical applications include:

• Aerial working platforms

• High-accuracy rotary platforms

• Solar tracking equipment

• Welding positioners

• Industrial rotary machinery

• Heavy-duty positioning equipment

For solar trackers, the drive can provide continuous rotary movement and stable positioning. In welding positioners and precision rotary platforms, its torque capacity, self-locking characteristics, and controlled backlash support accurate workpiece positioning.
