The size of drive sprocket mechanism can increase twice purpose.
In use, the equipment is arranged on the device needed first, when drive shaft rotates, installation can be driven
In adjusting rod mechanism rotation thereon；Adjusting rod mechanism will drive chain rotation；When driving axle rotary speed is ω, adjusting rod
When the original length of mechanism is L, the linear velocity of drive shaft driving adjusting rod mechanism apex is ω * L, 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 now drives
The linear velocity of dynamic chain is ω * L, will so be more than ω * L*0.866, so the difference of speed will cause chain to carry out echo
It is dynamic, so as to produce the phenomenon of fluctuation；When the square bar that stretched in drive sprocket mechanism does not extend out, the drive sprocket mechanism in the present invention
During rotation, the drive lower edge that the second expansion link will be with cylindrical piece eliminates undulating track motion, so that support
The runner movement that bar will be opened along support set, 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, so as to reach
The fluctuation on chain is eliminated, the gearratio of now drive sprocket mechanism driving driven sprocket mechanism is 1：1/1；When in drive sprocket
Flexible square bar along flexible square set stretch out when, drive sprocket mechanism size now will become original twice, install simultaneously
Sensing chip on stepped cylindrical guide block will sense that signal is started working, will during drive sprocket mechanism rotates
Chain movement is driven, the first chain link is by triggering cylinder, and triggering cylinder promotes elastic strip to be moved along the second T-slot, so that spacing
Groove contacts with limited block, so as to reach the zip length on chain is increased by twice, chain now will be in drive sprocket
Rotated in the presence of mechanism, when the triggering spine in driven sprocket mechanism contacts with trigger column, triggering spine will promote tactile
Post is sent out along the second guide groove movement, so that trigger column can promote elastic strip to move, so that elastic strip deforms, is become
The elastic strip of shape will now between groove and limited block to depart from, and the first chain link and the second chain link on chain now will
Separation, so as to adapt to the purpose of the indeclinable driven sprocket mechanism of size.
