FLEXIBLE DRIVE SHAFT
The transmission shaft is between the gear and gear shaft and provides power. Standard
transmission shafts are as shown in picture 1.
Flexible drive shafts have the characteristic of being easily adjustable over distance and are
greatly changeable, as shown in pictures 2, 3, and 4.
Another advantage is its flexibility. It can absorb impact and reduce vibrations. That is why
flexible drive shafts are commonly used in transportation vehicles such as cars and scooters.
