WITTENSTEIN has introduced the Miniaturized Galaxie®, a compact gearbox that showcases significant improvements over traditional harmonic gearboxes. This design features enhanced torsional rigidity, a larger hollow shaft diameter, and superior operational characteristics.
The Miniaturized Galaxie® operates on a different mechanical principle compared to conventional harmonic drives, resulting in mechanical behavior that is less reliant on the product's service life, thereby improving reliability and performance.
A key feature of the Miniaturized Galaxie® is its torque transmission mechanism. Unlike harmonic gearboxes that depend on two contact points, the Galaxie® gearbox employs direct contact among 24 teeth that engage simultaneously. This design greatly enhances torsional rigidity and eliminates backlash, a common drawback in harmonic systems.
The benefits of the Miniaturized Galaxie® include:
- High torsional rigidity: The rigidity is three times greater than that of traditional harmonic gearboxes.
- Zero backlash: This feature is maintained throughout the gearbox's lifespan, ensuring precision in various applications.
- Larger hollow shaft diameter: The shaft diameter exceeds that of harmonic gearboxes by over 50%, providing greater design flexibility.
- Higher torque density: With more teeth engaged in load transfer, the gearbox achieves over 40% higher torque density.
- Improved dynamic behavior: The rigid nature of the Galaxie® gearbox allows for quicker responses, enhanced accuracy, and superior durability under varying loads and direction changes.
Despite its advanced features, the Miniaturized Galaxie® maintains compact dimensions similar to those of harmonic gearboxes, making it a versatile choice for various applications. It also offers a range of input interface options, facilitating easy motor connections.
