I'm looking for some info/guidelines on designing bolted joints that are made to move with some resistance/friction...all without loosening the bolt. Think of a legs of a camera tripod; the legs can rotate in and out with resistance, but they never loosen.
It seems the basic idea is that the friction/torque securing the bolt (between the male/female threads) must be greater than the friction/torque created by the clamping effect of the bolt (between the bolt head and the moving part). So, some sort of thread locking technique is necessary (nyloc, loctite, etc).
I would be very interested hear any design guidelines/tips for these types of joints.
Thanks!
