Keyways can weaken shafts, and this study shows how much. Learn practical guidance for safer, stronger mechanical design.
This book analyzes how cutting keyways into circular shafts changes torsional strength. It compares the elastic limit of sections with keyways to solid sections, using a consistent basis for measurement. The work covers several shaft sizes and a variety of keyway shapes to illustrate the impact on performance and safety in design.
- How keyways affect strength and where the greatest losses occur
- A clear view of the testing setup, including the torsion machine and measurement approach
- The concept of efficiency for a shaft section with different keyways
- A catalog of keyway geometries and their observed effects on torsional behavior
Ideal for engineers, draftspeople, and students who want concrete, design-oriented insight into shafting and fastener interaction.
