Tapernøkler

Tapernøkler, also known as taper keys or wedge keys, are a type of mechanical fastener used to connect a rotating shaft to a hub or pulley. They are characterized by their trapezoidal or tapered cross-section, which is wider at one end and narrower at the other. This taper allows the key to be driven into a corresponding keyway in both the shaft and the hub, creating a secure interference fit.

The primary function of a tapernøkkel is to transmit torque between the shaft and the hub. As the shaft rotates, the key prevents the hub from slipping or rotating independently. The tapered design is advantageous because it allows for easy assembly and disassembly. The key can be hammered into place, expanding the fit and creating a strong mechanical lock. Conversely, it can be driven out from the opposite side to release the components.

Tapernøkler are typically made from materials like steel, chosen for their strength and durability. They are used in a wide range of applications, including industrial machinery, automotive components, and agricultural equipment where reliable torque transmission is essential. The precise dimensions and taper angle of the key are critical for optimal performance and depend on the specific shaft diameter and torque requirements of the application.
