Re: pic: 1747- Kicker Winch

Be careful of calculating the frictional forces on the gear you are pulling.
Are you pulling a dog gear ??

We are using a similar system but using 2 pneumatics ... the dog gear winds the capstan and the tension is held by a ratchet and pawl... we then pull the dog gear with a pneumatic and release the kick with the 2nd pneumatic which releases the pawl.

Our design engineer thought that the friction in the dog gear would be too great to pull effectively with a short throw pneumatic.

good luck..
cool design..

We are winding with a Banebot transmission and a FP motor.
