Ulwazi oluthile ngentambo

Ulwazi oluthile ngentambo

1. Ukuchazwa kochungechunge

Umucu ubhekisela ekumiseni okusonde, okuqhubekayo okunesiqephu esiphambanayo esithile esenziwe ngaphezu kwesisekelo esiyicylindrical noma esiyikholi. Imicu ihlukaniswe yaba imicu eyi-cylindrical kanye nemicu eyikhonikhi ngokuya ngokuma komzali wayo;

Ngokwesikhundla salo emzimbeni womzali, ihlukaniswe yaba imicu yangaphandle kanye nemicu yangaphakathi, futhi ngokuya ngesimo sayo se-cross-sectional (isimo sezinyo), ihlukaniswe yaba imicu engunxantathu, imicu engunxande, imicu ye-trapezoidal, izintambo ezihlukanisiwe, nezinye. imicu ekhethekile.

2. Ulwazi oluhlobene

Ukwenziwa kwentambo iwukuphuma okuqhubekayo okunomumo wezinyo ocacisiwe owenziwe eduze kwe-helix endaweni eyi-cylindrical noma eyi-conical. I-protrusion ibhekisela engxenyeni eqinile ezinhlangothini zombili zentambo.

Eyaziwa nangokuthi amazinyo. Ekucutshungulweni kwemishini, izintambo zisikwa ku-cylindrical shaft (noma ngaphezulu kwembobo yangaphakathi) kusetshenziswa ithuluzi noma isondo lokugaya.

Kuleli qophelo, i-workpiece iyajikeleza futhi ithuluzi lihamba ibanga elithile eduze kwe-axis ye-workpiece. Amamaki asikwe ngethuluzi ku-workpiece ayimicu. Intambo eyakhiwe endaweni engaphandle ibizwa ngokuthi intambo yangaphandle. Imicu eyakhiwe ebusweni bomgodi ongaphakathi ibizwa ngokuthi imicu yangaphakathi.

Isisekelo somucu yi-helix ebusweni be-axis eyindilinga. Iphrofayili yochungechunge ingahlukaniswa ngezinhlobo ezahlukene

Kukhona ikakhulukazi izinhlobo ezimbalwa zamaphrofayili entambo:

Intambo evamile (intambo engunxantathu): Izinyo lalo liwunxantathu olinganayo, eline-engeli yezinyo engu-60 degrees. Ngemuva kokuthi izintambo zangaphakathi nangaphandle zifakwe phakathi, kukhona igebe le-radial, elihlukaniswa libe izintambo ezimahhadlahhadla futhi ezicolekileyo ngokuya ngosayizi wephimbo.

Intambo yepayipi: Umumo wezinyo lemicu yepayipi elingavaliwe ingunxantathu we-isosceles, ene-engeli yezinyo engu-55 degrees kanye nekhona elikhulu eliyindilinga phezulu kwezinyo.

Izici zokuma kwezinyo zemicu yamapayipi avaliwe ziyefana nalezo zemicu yamapayipi angavaliwe, kodwa lisodongeni lwamapayipi ayi-conical, anomumo wezinyo we-isosceles trapezoidal kanye ne-engeli yezinyo engu-30 degrees.

Intambo ye-trapezoidal: Izinyo lalo liyi-isosceles trapezoid, ene-engeli yezinyo lama-degree angu-30, futhi lisetshenziswa kakhulu ku-screw mechanisms yokudlulisa amandla noma ukunyakaza.

Intambo engunxande: Izinyo lalo liyizikwele, kanti i-engeli yezinyo ilingana namadigri angu-0. Inezinga eliphezulu lokudlulisela phambili, kodwa ukunemba okuphansi kwe-centering namandla abuthakathaka ezimpande.

Intambo ehlanekezelwe: Izinyo lalo liwumumo we-trapezoidal ongalingani, eline-angle yeflank yezinyo engu-3 degrees endaweni yokusebenza. Umsuka wentambo yangaphandle inekona elikhulu eliyindilinga, futhi ukusebenza kahle kokudlulisela namandla kuphakeme kunezintambo ze-trapezoidal.

Ngaphezu kwalokho, kunezinye izintambo ezikhethekile ezimise okwe-V, izintambo zika-Whitney, izintambo eziyindilinga, njll. Lawa maphrofayili entambo anezici zawo futhi akhethiwe futhi asetshenziswe ngokuvumelana nezimo ezihlukahlukene zohlelo lokusebenza.
