RINGSPANN HUB CONNECTIONS
Hub connections allow for co-axial installation of shafts and components onto shafts with minimal effort, while still enabling easy disassembly. The use of hub connections is justified when there is a need to quickly and reliably fix two shafts, a shaft and a wheel (pulley, drum, disc, etc.), or a shaft within a bore.
Advantages and Applications of Ringspann Hub Connections
Structurally, such a connection consists of movable parts, with the compressive or expansive force applied through tightening screws, bolts, or supporting springs. The advantages of hub connections include:
– Simple design;
– Easy installation and disassembly;
– No need for shaft machining or weakening by cutouts (unlike keyway, spline, and other connections);
– Ability to adjust the fixation force and position on the shaft.
These advantages provide a wide range of applications for hub connections and their constructive feasibility, making them one of the most effective solutions in their field.
Ringspann offers hub connections for various applications, including:
CLAMPS
Clamps can be designed in a two-part or three-part construction.
