Partes acus Structure:
Acus gestus sunt cylindro gestus cum scutulis cylindricis. Cylindri sunt tenues et longi ad diam. Hoc genus cylindrus dicitur acus cylindrus. Licet baiulationem parvam sectionem habeat, portans tamen magnum onus ferens facultatem habet. Acus germen tenuibus et longis scutulis instructum est, ita structura radialis compacta, cuius capacitas interior et diametri oneris eadem sunt cum aliis generibus gestuum.
Acus cylindrus gestus maxime aptae sunt ad structuras sustentandas cum dimensionibus radialibus institutionis limitatis.
Neelde cylindrus gestus late in machinis celeritatis variabilibus adhibentur, exempli gratia, autocineta, agricolae, instrumenta machinae, etc.
Features:
1. Anulus exterior rotundi acus cylindrus calicis baiulans impedimentum static idoneum cum capsula ferente adoptat, nec axialem figendi fabricam requirit.
Potest efficere flexibilem operationem suam perficiendi etiam sub magna celeritate et gravi onere condiciones.
2. Poculum acus cylindrus instructus principium ductum est, quod corpus magnum volumen obsignatio adipe habet, quod sine lubricatione diu relinqui potest.
Ob caliditas lubricationis intervallum, operatio diuturnum sine molestia curare potest.
3. Occupat exiguum spatium, quod ad ex pacto machinandi consilium conducit.
Detractus poculi acus cylindrus gestationes plerumque anulo interiori non indigent, propter rationem eius IR anulus interior typus adhiberi solet.
4. Detractus poculi acus cylindrus gestus in duos fines perforati gerentis (HK type) et unum finem gerentis generis clausis (BK type).
5. In extremo typo signati gerens acus cylindrus extracti calicis ferens signatus est, qui ad extremum scapo idoneus est et parvam axialis vim liberam sustinere potest.
