🔍 Key Concepts

• Input vs. output shaft alignment in different gear types • Basic geometry of parallel, bevel, worm, and epicyclic gears • How power is transmitted when shafts are in-line, intersecting, or at an angle

💭 Think About

• For each gear type, picture or sketch the relative position of the shafts: do they stay collinear, cross at an angle, or offset? • Ask yourself: which type of gearing is commonly used when you want to change speed/torque but keep the same shaft centerline? • Which of these gear types is often used in marine main reduction gears where the engine crankshaft and propeller shaft share a common line?

✅ Before You Answer

• Verify which gear type keeps input and output shafts on the same axis (collinear) • Eliminate any gear types where the shafts are clearly at 90° or non-collinear • Confirm from basic machine design that the chosen gear set is known for coaxial (in-line) shaft arrangements
