I'm making a DIY version of the Kwikset Smartcode. So basically I need a motor to lock/unlock my door while still working flawlessly with the key. However I want a different clutch system. They use a dog clutch with 180 degrees free turning to allow the key to rotate. However this means that the...

Sorry for late reply, I must of missed it somehow. 1) as little as possible since it will be battery powered and the motor will only have like 5W 2) yes, there will never be an engagement when one of the shafts is rotating 3) preferably smooth, but not necessary 4) either shaft2 should rotate...

Thanks for the reply! It will rotate at a maximum of 100 RPM (freerun) probably and a maximum of 2Nm (stall) torque. Yes it operates in both directions. I have briefly looked at centrifugal clutches but haven't found any that are small enough (must fit in 3cm^3). Also, when motor turns at let's...

Hi, I made an electronics project but I'm having some mechanical problems. Particularly, I'm having issues finding a good clutch for my problem. What I'm trying to do: A motor is connected to shaft 1, a human can manually rotate shaft 2. I want that when the motor isn't doing anything, a...

Thanks for the reply! But let's say that there is a little slip due to the 2 parts not fitting perfectly, and maybe some material deformation (the object I'm using to turn the heads is made out of ABS plastic). Could the shape of the knob matter in this situation? That is, would it be easier for...

Actually, the more I think about it the more I'm coming to the conclusion that "if there is no slip, 100% of torque is transfered", the internal forces just vary with the different shapes but ultimately all torque is transfered. Anyway, some help is always welcome =).

I'm wondering what the most efficient way to transfer torque is. I'm not talking about which shape can handle the most torque but rather how can I transfer 100% of the torque. Let's take screw bits for example. It seems to me that the simple slotted or philips head transfer 100% of the torque...
