Metal bellows couplings KG-HS

Metal bellows couplings KG-HS

Product catalog summary

Overview: The document provides technical specifications for high-speed metal bellows couplings, specifically the KG-HS series, designed for optimal performance in drive technology applications. These couplings feature a rotationally symmetrical clamping hub for superior balancing quality.

Specifications: The couplings are available in various sizes, each with specific technical parameters such as moment of inertia, torsional stiffness, maximum shaft misalignment, and spring rates. The maximum operating speed (nmax) varies by size, with the highest being 80,000 upm for size 5.

Materials: The bellows are made from stainless steel 1.4571, while the hubs are constructed from stainless steel 1.4301 for sizes 5-10 and steel (St52) for sizes 40-400. Screws conform to ISO 4762 / 12.9 standards.

Temperature Range: The couplings can operate within a temperature range of -40°C to +350°C.

Construction: The connection between bellows and hubs is achieved through a micro-plasma welding process. Three standard variants are available, featuring 2, 4, or 6 corrugated metal bellows.

Dimensions: Length dimensions adhere to DIN ISO 2768 cH standards. Specific dimensions and mass are provided for each size variant.

Recommendations: For operating speeds around 0.3 x nmax, additional balancing is recommended to achieve a balancing quality of G 2.5.

Ordering Information: Examples of order configurations are provided, indicating the size, variant, and dimensions required.
