Wittenstein’s Miniaturized Galaxie Gearbox
Wittenstein, a pioneering leader in the field of mechatronic drive technology, has introduced a game-changing innovation: the miniaturized Galaxie gearbox. This newly developed gearbox combines exceptional torsional rigidity, superior torque density, and true zero backlash, making it a game-changer in the field of power transmission. In this article, we will delve into the features and benefits of this remarkable creation, exploring its potential applications in various industries and shedding light on its revolutionary capabilities.
Miniaturized Galaxie Gearbox Characteristics
Smaller Size with Axial Power Transmission
The miniaturized Galaxie gearbox presents a remarkable design innovation by utilizing axial power transmission instead of radial transmission. This ingenious approach involves the axial movement of single teeth within a gear ring, driven by a polygonal disc with two high points. The teeth engage with a flat wheel featuring special helical crown gearing, creating a screw-like movement. The "crown" teeth have more flanks per tooth, resulting in increased flank surface area and enabling near-complete surface contact when meshed. This differs significantly from strain wave gearboxes that rely on linear contact. Additionally, the polygonal disc movement in the Galaxie ensures the majority of crown teeth contribute to torque transmission and torsional rigidity. The result is three times better rigidity compared to strain wave gearboxes. Furthermore, the crown tooth concept empowers the new Galaxie to achieve impressive ratios, with i=60/61 and even higher possibilities, catering to the demanding requirements of robotics applications.
Large Hollow Shaft: Ample Space for Cables, Leads, and Penetrations
The axial kinematics of the miniaturized Galaxie gearbox not only enable compact sizes but also create additional space within the gearbox itself. One significant advantage is the substantial increase in the hollow shaft diameter. For instance, in size 90, the Galaxie offers an almost 50 percent larger hollow shaft diameter compared to strain wave gearboxes with the same footprint. With a hollow shaft diameter of 31 millimeters, there is ample room for cables, leads, and other connections, enabling more efficient cable management within robots. Additionally, the larger bending radii made possible by the Galaxie gearbox significantly reduce the risk of cable breakage.
From 90 Nm to Over 7500 Nm from a Single Source
Regardless of whether the kinematic principle is radial or axial, WITTENSTEIN's Galaxie class of gearboxes covers a wide range of applications. The miniaturized Galaxie gearbox, along with its larger counterparts, is available in sizes ranging from 90 mm to 300 mm in outer diameter. These gearboxes deliver impressive acceleration torques, starting from 150 Nm and reaching an astonishing 7500 Nm. This extensive range of torque options, provided by a single-source manufacturer, solidifies the Galaxie gearbox as an unrivaled solution in the industry.
Wide Range of Applications
The miniaturized Galaxie gearbox caters to a wide range of applications, where precision, compactness, and efficiency are critical factors. In the field of medical and precision robotics, the gearbox's exceptional rigidity and torque density enhance the performance of surgical robots, enabling more precise and delicate procedures. Semiconductor and wafer handling systems benefit from the gearbox's compact design, ensuring optimal space utilization and reliable power transmission. High-end machine tools, which demand high torque density and efficiency, find their perfect match in the miniaturized Galaxie gearbox, empowering manufacturing processes with unparalleled precision and reliability.
