Specific implementation mode
Operation principle of the present invention：When using 1 worm gear shaft as driving link, when 3 outer shrouds are driven member, both to revolve counterclockwise
Turn, as long as the speed of 3 outer shrouds is less than the speed of 1 worm gear shaft, 1 worm gear shaft will force 2 transition blocks to expand outwardly by roller, and
Locked by being surrounded outside roller and 3, freewheel clutch is at locking state.
When the speed of 3 outer shrouds is more than the speed of 1 worm gear shaft, 3 outer shrouds are in and surmount just not by the power of 1 worm gear shaft
State.
Due to being all that roller is contacting between all movement parts, 3 outer shrouds only have rolling friction when surmounting, and surmount easily
Fast, heat production is few.
The huge increment of the uniform increments characteristic of involute and 360 ° of spiral cambers, but also locking is steadily and reliable.
Especially 5,6 magnetic force pre-tightening apparatus, the structures without other preload synchronizing device complexity and high-frequency movement,
