Conical Clamps

Conical clamps are mechanical elements for the firm and reliable attachment of rotating components (e.g., gears, pulleys, sprockets) to a shaft without the use of keyways. They operate on the principle of mechanical friction created by compressing two or more conical rings using screws. When the screws are tightened, the inner ring compresses against the shaft, while the outer ring expands into the hub of the element, creating an exceptionally strong connection capable of transmitting high torque and axial forces.

Since this system does not require keyways, it eliminates notch effects and weakening of the shaft, while allowing for arbitrary angular and axial adjustment of the element during assembly. Conical clamps are self-centering and provide a high degree of concentricity, which is crucial in drives with high speeds or frequent direction changes. Due to their easy assembly and disassembly, they are ideal for modern machine construction, where precision, robustness, and quick maintenance are required without the risk of damaging expensive components.
