Axial movement in a gear-type flexible coupling is provided for by _______________.
AI Explanation
The correct answer is C) gear teeth on the floating member sliding between internal teeth on the shaft ring.
In a gear-type flexible coupling, the axial movement is provided for by the floating member, which has gear teeth that slide between the internal teeth on the shaft ring. This allows for some axial play or movement between the coupled shafts, which is necessary to accommodate shaft misalignment or expansion.
The other answer choices are incorrect because:
A) Adjusting the pitch of the teeth is not how axial movement is provided for in a gear-type flexible coupling.
B) The variable oil clearance in the quill shaft is not related to the axial movement mechanism.
D) The gears do not slide on their shafts between retaining collars to provide axial movement in this type of coupling.
