🔍 Key Concepts

• Notice the labels oil inlet, oil outlet, and floating member and think about what type of connection needs lubrication inside the coupling. • Compare the internal teeth shown in Section A-A with how different couplings and clutches are constructed (gears vs. friction plates vs. solid shafts). • Consider which options would reasonably have pinion flange and turbine flange connected through a lubricated, toothed element.

💭 Think About

• Which of the listed devices is designed to transmit torque through meshing teeth that must be lubricated, rather than through friction plates or a solid shaft? • If a device has a floating member between two flanges, what is that member likely doing—providing flexibility, direct rigid connection, or hydraulic engagement? • Look at whether a quill shaft or solid coupling would realistically need oil inlets and outlets arranged as shown in the illustration.

✅ Before You Answer

• Verify which choices typically contain internal gear teeth and require continuous lubrication. • Check whether a hydraulic clutch drawing would usually show multiple friction plates or chambers instead of gear teeth. • Eliminate any option that would not logically use a floating member between a pinion flange and turbine flange.
