Which of the following methods provides for...

🔍 Key Concepts

• How axial movement (movement along the shaft’s length) is usually accommodated in gear-type flexible couplings • The difference between sliding teeth in a gear mesh vs. the entire gear sliding along the shaft • What kinds of motion (axial, radial, angular) typical flexible couplings are designed to absorb

💭 Think About

• Which choice describes parts sliding along the shaft axis rather than just tipping, flexing, or moving radially? • In a gear-type flexible coupling, what component usually moves to take up changes in distance between shaft ends: the shaft itself, the gear on the shaft, or the meshing teeth? • Which option is clearly about axial clearance in the coupling teeth, not about balancing thrust or radial play?

✅ Before You Answer

• Identify which option specifically mentions sliding motion in the direction of the shaft axis. • Eliminate any choices that mainly discuss radial motion or thrust balancing rather than axial freedom. • Think about how a "floating" member with teeth could allow endwise movement without disengaging the coupling.

Which of the following methods provides for axial movement in a gear type flexible coupling?

External teeth on the floating member are allowed to slide between internal teeth on the shaft rings.

Each gear is allowed to slide on its shaft between retaining collars.

A coupling permits free relative radial motion of the gear and pinion, thereby allowing axial movement.

Opposing helices act to balance axial thrust with the coupling.
