Or the effect of hydraulic oil driving is the first guide groove movement that flexible square bar is opened in flexible square set, to reach
The size of drive sprocket mechanism can increase twice purpose.
In use, the equipment is mounted on the device needed first, when drive shaft rotates, installation can be driven
Adjusting rod mechanism rotation on it；Adjusting rod mechanism will drive chain rotation；When driving axle rotary speed is ω, adjusting rod
When the original length of mechanism is L, it is ω * L that drive shaft, which drives the linear velocity of adjusting rod mechanism apex, assigns to the horizontal line on chain
Speed is ω * L*0.866, and for traditional sprocket wheel in drive chain rotary course, when rotating 30 degree, sprocket wheel at this time drives
The linear velocity of dynamic chain is ω * L, will be more than ω * L*0.866 in this way, so the difference of speed will make chain carry out echo
It is dynamic, the phenomenon that generate fluctuation；When the square bar that stretches in drive sprocket mechanism does not extend out, the drive sprocket mechanism in the present invention
During rotation, the second telescopic rod will eliminate undulating track movement with the drive lower edge of cylindrical piece, so that support
The runner movement that bar will be opened along supporting sleeve, so that the length of adjusting rod mechanism changes, so that driving
Each moment of chain-wheel mechanism rotation can ensure that the linear velocity of adjusting rod mechanism is ω * L*0.866, to reach
The fluctuation on chain is eliminated, the transmission ratio of the driven sprocket mechanism of drive sprocket mechanism driving at this time is 1：1/1；When in drive sprocket
Flexible square bar along stretch square set stretch out when, drive sprocket mechanism size at this time will become original twice, install simultaneously
Sensing chip on stepped cylindrical guide block will sense that signal is started to work, will during drive sprocket mechanism rotates
Chain movement is driven, for the first chain link by triggering cylinder, triggering cylinder pushes elastic strip to be moved along the second T-slot, so that limit
Slot is contacted with limited block, and to reach so that the zip length on chain increases by twice, chain at this time will be in drive sprocket
It is rotated under the action of mechanism, when the triggering spine in driven sprocket mechanism is contacted with trigger column, triggering spine will push tactile
Column is sent out along the second guide groove movement, so that trigger column can push elastic strip to move, so that elastic strip deforms, is become
The elastic strip of shape will now to be detached between slot and limited block, and the first chain link and the second chain link on chain at this time will
Separation, to adapt to the purpose of the indeclinable driven sprocket mechanism of size.
