What shape does the end of a crankshaft typically have?

The end of a crankshaft typically has a tapered shape to facilitate the proper fitment and alignment with other engine components, such as the flywheel or the timing gear. The taper provides a precise way to connect these elements, ensuring that they can transmit torque efficiently while minimizing the risk of slippage. This design feature helps in maintaining optimal function within the engine, contributing to effective power transfer and overall performance.

The taper also assists in simplifying assembly, allowing for easier alignment during installation. The angle of the taper can vary based on the specific design and application of the crankshaft, but the general principle remains consistent across different types of engines. This specificity is crucial in achieving the desired mechanical interactions necessary for engine operation.
