Clutch Coupling

 Clutch Coupling

Clutch used to transmit power by tow shaft, the torque transmitted by friction between disks.

How It Works

 E  -  Input shaft  A  -  Pawl    B - Clutch teeth    C - Sliding compound   D  - Helical Splines  

 F  - Out Clutch                           G - ratchet teeth

1)- When the input shaft and sliding component reach the same speed as the output, they rotate until a ratchet tooth contacts the tip of a 

 this prevents further rotation of the sliding component relative to the output clutch ring (position shown).

2)- As the sliding component moves along the input shaft, the pawl passes out of contact with the ratchet tooth, allowing the clutch teeth to come into flank contact and continue the engaging travel. Note that the only load on the pawl is that required to shift the lightweight sliding component along the helical splines.

 3)-Driving torque from the input shaft will only be transmitted when the sliding component completes its travel by contacting an end stop on the input shaft , with the clutch teeth fully engaged and pawls unloaded
