Commonly, Ferris wheels are the supreme attraction of theme parks and amusement parks and in some well-known cities of the world have even established themselves as famous landmarks that are tourist magnets. Modern designs are usually made of steel and are provided with four inclined beams converging on a non-driven hub. The inevitable problem: The higher a Ferris wheel is, the more the steel construction tends to deviate from optimum concentricity. In order to ensure a constantly even transmission of the actuating power of the electric motors to the impellers of the Ferris wheel nevertheless RINGFEDER® has developed an individual traction device. This device uses a specially designed, maintenance-free friction spring to provide for the flexible adjustability of the traction force and reliably ensures that drive components and output components always remain in contact with each other – even under strong thermal impacts by heat or chilliness, which additionally influence the concentricity of the Ferris wheel.
Many special requests, one appropriate RINGFEDER® solution: In the field of special processing machines, e.g. laser cutting tools, sawing machines or shredders, rotationally elastic jaw coupling of the RINGFEDER® GWE series just as torsionally stiff metal bellows couplings of the RINGFEDER® GWB type are the preferred choice. Intelligently attuned to the specific requirements of the respective application, they prove to be powerful, reliable and compact shaft connections, for instance in main spindle and positioning drives the speeds of which are continuously increasing. They feature ideal damping characteristics, effectively compensate for any misalignments and are extremely installation- and maintenance-friendly.
