Q

Turbine disks are commonly attached to the shaft by which of the following methods?

🔍 Key Concepts

• How turbine disks must be secured to a rotating shaft to safely transmit high torque and high rotational speeds • Typical mechanical joining methods used in high-speed rotating machinery (e.g., keys/splines, shrink fits, bolts, pins, locking devices) • Why permanent methods (like welding) are often avoided on highly stressed rotating parts such as turbine rotors

💭 Think About

• Think about which methods provide precise alignment and strong, even clamping around the shaft without creating stress concentrations or making removal impossible • Consider which options are more appropriate for low-speed, light-duty connections versus high-speed, high-energy turbine rotors • Ask yourself: which methods would manufacturers prefer if they need to periodically disassemble or replace individual turbine disks on the shaft?

✅ Before You Answer

• Check which choices involve permanent joints that would be hard to inspect or replace during overhauls • Check which methods are commonly used to prevent rotational slip between disk and shaft while still allowing assembly/disassembly • Eliminate any methods that would likely create stress risers or be unsafe at high RPMs for critical rotating machinery
