A mechanical component used to transmit torque between a shaft and a hub, such as on a drive pulley or gear, preventing relative rotation.
A key or spline is a precision-engineered mechanical element designed to create a positive, non-slip connection between a rotating shaft and a mounted component like a drive pulley, gear, or coupling. It functions by fitting into matching grooves (keyways or splines) on both parts, ensuring synchronous rotation and torque transmission without slippage. Keys are typically single, rectangular, or tapered elements, while splines consist of multiple, parallel ridges or teeth along the shaft and hub, offering higher torque capacity and better alignment.

A key is a single piece (e.g., rectangular) that fits into keyways, suitable for moderate torque. A spline has multiple teeth along the shaft and hub, offering higher torque capacity, better alignment, and often used in automotive or high-precision applications.
Consider torque requirements, shaft diameter, hub material, and operating conditions (e.g., speed, load cycles). Refer to standards like ISO 7732 for dimensions and consult engineering tables for shear strength calculations.
Shear failure from overload, wear due to fretting or misalignment, and corrosion in harsh environments. Proper fit, material selection, and lubrication can mitigate these.
