Modern drive concepts feature high dynamics, energy efficiency and increasingly compact dimensions, under the banner of high power density paired with outstanding energy efficiency. Requirements made for the Spinplus.
The Spinplus: a compact-sized coupling system with extremely low rotational inertia
The core of the Spinplus coupling is the functional element responsible for its operating and performance parameters. This new functional element is based on the principle of a parallel link system with flexure hinges and enables universal displacement compensation - i.e. compensation for radial, axial and angular shaft misalignments - in one plane. As a result of this ability, the backlash-free coupling is advantaged by an overly short design and high performance density, combined with extremely low rotational inertia.
Innovative clamping hub design optimises the concept
In addition, the newly-developed, innovative hub design further optimises the concept of this torsionally stiff coupling in terms of reduced rotational inertia. These aluminium clamping hubs contribute to further reducing this parameter, as against conventional hubs. In this connection, two hub versions were designed to meet the respective application requirements. Equipped with offset clamping hubs, version A of the coupling is focused on providing the lowest possible rotational inertia. Version B is designed to accommodate large shaft diameters and features the shortest possible overall length. The clamping hubs are also anodised for corrosion protection.
