2 outer end of the connecting shaft is equipped with the positioning step 29 to match with cover board 7.
The application method of the utility model is as follows：
When installing chain, staff can be removed cover board 7 by screwing out screw 8, and staff can be light by being open
Pine installs chain to wheel teeth portion 3, and after installation is complete, then by the locking cover board 7 of screw 8, when body-building, personnel pass through
When pushes pedals drive chain, chain can then drive the wheel teeth portion 3 of fan gear to rotate, and as wheel teeth portion 3 rotates, shaft 1 is just
It can be rotated with motor car wheel, in the case where shaft 1 rotates, fan gear then will produce centrifugal force, and be pressurized ball 13 in centrifugal force
Under the action of get rid of outward, to squeezing elastic membrane 12, so that elastic membrane 12 is deformed towards epicoele 1001, at this time epicoele
1001 spaces become smaller, and 1001 air pressure inside of epicoele becomes larger, and the high pressure draught in epicoele 1001 will be entered by pressure inlet 20
In Pressure channel 19, the air column with high pressure can be formed into air-flow of the Pressure channel 19 after interior, and impinge upon on only oiled-plate method 23
End, make only oiled-plate method 23 move down, only oiled-plate method 23 starts in retraction stroke hole 21, and only oiled-plate method 23 no longer separates connecting tube 17, this
Carving elastomeric bladder 14 can be connected by connecting tube 17 and oil discharge passage 16, and elastomeric bladder 14 generates after script is strutted by lubricating oil
Elastic reaction under start to shrink at, when elastomeric bladder 14 starts to shrink at, elastomeric bladder 14 its internal lubricating oil will be squeezed out to
In connecting tube 17, and be delivered in oil discharge passage 16 by connecting tube 17, then from oil outlet 15 spray, leaching in wheel teeth portion 3 on,
With the rotation of wheel teeth portion 3, the case where can adequately be lubricated between wheel teeth portion 3 and chain, avoid the occurrence of rustization, and with
It damping personnel and tramples that speed is faster, the centrifugal force of generation is just bigger, and increased air pressure is just bigger, the degree that only oiled-plate method 23 is opened
Also bigger, oil pump capacity also becomes larger therewith, can avoid wearing between wheel teeth portion 3 and chain to the full extent, extend wind
The service life of elevating arc.
Only 23 upper end of oiled-plate method is in the arcuation of indent, and more conducively high pressure gas concentration is applied 23 upper end of oiled-plate method to end to stopping oiled-plate method 23
Plus-pressure is further ensured that sensitivity when only oiled-plate method 23 is turned on and off.
5 bottom of protective cover is bolted with oil storage bag 24, after lubricating oil is sprayed from oil outlet 15, is dropped in wheel teeth portion 3
Lubricating oil will not be utilized completely, and being unable to get the lubricating oil utilized will under the effect of gravity be dropped in oil storage bag 24,
So that lubricating oil is put aside, to wait for being utilized later, lubricating oil is avoided to be wasted, and oil storage bag 24 is elastic material, it can
Effectively increase oil storage bag 24 oil reserve of itself.
9 bottom of mounting blocks is equipped with oil filler point 25, is connected by elastic tube 26 between oil filler point 25 and elastomeric bladder 14, oiling
It is bolted with sealing-plug 27 at hole 25, when needing to refuel, sealing-plug 27 is screwed out, is refueled for convenience, it can be first by oil filler point
Then 25 rotations are injected lubricating oil by oil filler point 25, and elastic tube 26 elastic material of itself can have to top
Effect avoids elastic tube 26 from impacting the contraction of elastomeric bladder 14, ensures fuel-displaced effect.
