Abstract
The design of shafts and keyways is a critical aspect in mechanical engineering, especially in the transmission of rotary motion and torque. Shafts serve as the primary support structures for various components such as gears, pulleys, and bearings, ensuring efficient power transfer within mechanical systems. The keyway is a crucial feature in shaft design, enabling the secure attachment of components like gears or pulleys to the shaft without the risk of slipping. The dimensions and geometry of both the shaft and the keyway are determined based on factors such as material properties, load conditions, rotational speed, and safety factors. Proper design of these elements ensures longevity, reliability, and optimal performance of the machine or system. The design process typically involves selecting an appropriate shaft material, such as steel or alloy, based on mechanical properties like tensile strength and fatigue resistance. The keyway, often designed as a rectangular or square cut into the shaft, must accommodate a corresponding key that fits snugly to prevent slippage. Considerations such as key material, tolerances, and keyway depth are critical to ensuring that the components remain securely fastened under load and do not experience premature wear or failure. The paper also explores the effect of factors like dynamic loading, thermal expansion, and manufacturing tolerances on shaft and keyway design. Advances in materials science, manufacturing processes, and finite element analysis (FEA) have significantly improved the precision and performance of shaft and keyway designs, allowing for the creation of more efficient and durable systems. The aim of this study is to provide a comprehensive understanding of the factors influencing shaft and keyway design, offering guidelines for engineers and designers to optimize performance while minimizing potential failures. Here are key keywords and phrases commonly used in the design of shafts and keys. These are useful for understanding concepts, conducting research, or preparing notes and presentations.
