Above-mentioned said small size bearing is the small size deep groove ball bearing.
Above-mentioned said large scale bearing is the large scale deep groove ball bearing.
In the above-mentioned said upper shaft-cup dust-proof cushion is housed.
Above-mentioned said lower shaft-cup is in-built dust-proof cushion.
The link at above-mentioned said axle and synchronous pulley place is jackscrew.
Wherein: 1 is bar, and 2 is lower shaft-cup, and 3 is dust-proof cushion, and 4 is axle sleeve, and 5 is small size bearing, and 6 is axle, and 7 is the large scale bearing, and 8 is upper shaft-cup, and 9 is synchronous pulley, and 10 is gripping sleeve, and 11 fasten lid for axle, and 12 is clutch.
Working principle of the present utility model: the utility model can be used for medicament dissolution instrument, cooperate bar and the clutch of medicament dissolution instrument to use, when using this axle to be, need bar is inserted in the axle, clutch is fixedly connected with bar, and then outer six sides with clutch place axle to fasten within interior six sides of lid.When this axle ties up to work, motor drives synchronous pulley by Timing Belt, because synchronous pulley is fixedly connected with axle, synchronous pulley is fastened lid with axle again simultaneously and is fixedly connected with, axle is fastened lid and is fixed by hexagonal shaped with clutch and is connected, bar is fixedly connected with clutch, therefore bar, clutch, synchronous pulley, axle, axle are fastened to cover and are fixed as one, when motor drives the synchronous pulley rotation by Timing Belt, under the effect of large scale bearing and small size bearing, in axle sleeve, rotate simultaneously final driven rod smooth rotation with moving axis.
Superiority of the present utility model: the seize problem that 1, has solved bar when doing long-time drug dissolution test.2, reduce processing technology, adopt lightweight material to reduce cost.3, increasing axle is campaign-styled stability, reduces the oscillating quantity of oar.4, increase dust-proof cushion minimizing soda acid water vapour and impurity and enter in the axle, increase the service life.
(4) description of drawings:
Fig. 1 is the exploded view of the related digestion instrument bar of the utility model rotation axis system.
Fig. 2 is the axonometric drawing of the related digestion instrument bar of the utility model rotation axis system.
Fig. 3 is the sectional view of the related digestion instrument bar of the utility model rotation axis system.
Wherein: 1 is bar, and 2 is lower shaft-cup, and 3 is dust-proof cushion, and 4 is axle sleeve, and 5 is small size bearing, and 6 is axle, and 7 is the large scale bearing, and 8 is upper shaft-cup, and 9 is synchronous pulley, and 10 is gripping sleeve, and 11 fasten lid for axle, and 12 is clutch.
(5) embodiment:
Embodiment: a kind of bar rotation axis system (seeing Fig. 1-3) is characterized in that it is fastened by lower shaft-cup 2, axle sleeve 4, small size bearing 5, axle 6, large scale bearing 7, upper shaft-cup 8, synchronous pulley 9, gripping sleeve 10 and axle to cover 11 and consist of; The bottom assembling small size bearing 5 of said axle 6, the top assembling large scale bearing 7 of axle 6, the axle 6 that has assembled small size bearing 5 and large scale bearing 7 is positioned at axle sleeve 4, the top fit on shaft-cup 8 of said axle sleeve 4, the lower shaft-cup 2 of the bottom assembling of axle sleeve 4, said axle 6 is fixedly connected with according to link with synchronous pulley 9, the one end assembling gripping sleeve 10 of said synchronous pulley 9, and an end and the axle of synchronous pulley 9 are fastened and are covered 11 and be fixedly connected with, and said gripping sleeve 10 is positioned at axle and fastens and cover 11 inside.
