Spring based (energetic) locking mechanisms:
Gears, bearings, gearbearings:
Misc:
- Collet mechanisms
- Chuck mechanisms
- Machine taper ... rather not applicable at nanoscale as it exploits friction self holding
- goniometers in assembly line orienting stage
Rotating shaft couplings
Wikipedia: Category:Rotating_shaft_couplings
Axle across angle mechanisms:
- universal joint (does not preserve constant rotation speed) - double Cardan joint does
In general: CV joints [1]
- double Cardan joint does (2 universal joints)
- tripod joint – Video: 2014-04-04 – thang010146 – Tripod joint 1
- Tracta joint
- Rzeppa joint (depends on balls)
Off center axle continuation mechanismss:
- Oldham coupling
- Schmidt coupling
Chains:
Rigid chain mechanisms:
Gentle bending high degree of motion flextures:
- Scrollerwheel
- Rolamite, expireed US patent: [2]
