SG-l Spur Gear Slewing Drive: Compact, Fast, and Cost-Effective Rotation for Smart Systems
What is an SG-l Spur Gear Slewing Drive?
The SG-l Spur Gear Slewing Drive is a compact rotary actuator that uses a spur gear instead of a worm gear to transmit rotational motion. This configuration offers higher rotational speed and better transmission efficiency, making it suitable for applications requiring rapid movement, lower torque, and frequent direction changes.
As part of LDB’s SG Series, the SG-l is engineered for smart systems where performance, footprint, and cost need to be balanced. It is widely used in robotics, automation, light-duty solar tracking, and mobile platforms.
Structural and Functional Advantages
Spur Gear Efficiency
Spur gears provide higher mechanical efficiency (up to 95%) compared to worm drives, allowing faster rotational speeds with minimal energy loss.
Lightweight and Compact
The SG-l is designed for installations where space and weight constraints are critical. It integrates a small slewing bearing, spur gear system, and motor mounting hub.
Bidirectional Rotation with Low Backlash
Ideal for repetitive and fast directional changes, the SG-l ensures smooth operation with minimal play between gear teeth.
Versatile Mounting and Integration
Standard mounting interfaces allow the drive to be used with a wide range of stepper motors, brushless DC motors, or gear reducers.
Open or Semi-Enclosed Options
Available in open-frame for indoor use or semi-sealed designs with splash protection for light outdoor environments.
Application Scenarios
Collaborative Robots (Cobots): Providing agile base or arm rotation.
Automated AGVs and AMRs: Allowing quick 360° navigation with efficient power usage.
Portable Solar Panels and IoT Devices: Tracking sunlight without the need for heavy-duty worm gears.
Camera Gimbals and Sensors: Lightweight platforms needing smooth, quiet rotational adjustment.
Exhibition and Display Automation: Spinning platforms, signage, and product showcases.
