Rumwe ruzivo nezve thread

1, Thread Tsanangudzo

Thread inoreva spiral shaped, inoenderera mberi neyakachinjika-chikamu yakagadzirwa pamusoro pecylindrical kana conical base. Shinda dzakakamurwa kuita cylindrical shinda uye conical shinda zvinoenderana nechimiro chemubereki wavo;

Zvinoenderana nechinzvimbo chayo mumutumbi wemubereki, yakakamurwa kuita shinda dzekunze uye shinda dzemukati, uye zvinoenderana neyakachinjika-chikamu chimiro (mazino chimiro), yakakamurwa kuita tambo nhatu, rectangular shinda, trapezoidal tambo, serrated shinda, nezvimwe. shinda dzakaumbwa.

2、 Ruzivo rwakabatana

Thread machining inoramba ichikwira ine chimiro chezino chakatsanangurwa chakaumbwa pamwe nehelix pane cylindrical kana conical surface. Protrusion inoreva chikamu chakasimba pamativi ese eshinda.

Anozivikanwawo semazino. Mukugadzira michina, tambo dzinochekwa pane cylindrical shaft (kana mukati mukati megomba pamusoro) uchishandisa chishandiso kana vhiri rekukuya.

Panguva ino, workpiece inotenderera uye chimbo chinofambisa imwe chinhambwe pamwe chete neaxis ye workpiece. Iwo mavanga akachekwa nechishandiso paworkpiece ishinda. Shinda inoumbwa pamusoro pekunze inonzi shinda yekunze. Shinda dzakaumbwa pamusoro pegomba remukati dzinonzi shinda dzemukati.

Hwaro hweshinda ndiyo helix iri pamusoro pedenderedzwa axis. Iyo tambo profile inogona kukamurwa mumhando dzakasiyana

Kune kunyanya akati wandei marudzi eshinda profiles:

Rwendo rwenguva dzose (shinda yetriangular): Kuumbwa kwezino rayo igonyo yakaenzana, ine kona yemazino inosvika madhigirii makumi matanhatu. Mushure mekunge tambo dzemukati nekunze dzapindirwa mukati, pane gap reradial, iro rakakamurwa kuita shinda dzakakora uye dzakatsetseka zvichienderana nehukuru hwenamo.

Tanda yepombi: Chimiro chezino cheshinda dzepombi dzisina kuvharwa igonyo retatu reisosceles, rine kona yemazino e55 degrees uye kona hombe yakatenderedzwa kumusoro kwezino.

Mamiriro emazino emhando dzepombi dzakavharwa akafanana neasina kuvharwa pombi shinda, asi iri pamadziro epombi yeconical, ine isosceles trapezoidal mazino chimiro uye zino angle ye30 madhigirii.

Trapezoidal shinda: Zino rayo chimiro isosceles trapezoid, ine zino angle ye 30 madhigirii, uye rinoshandiswa zvakanyanya mukusevha michina yekufambisa simba kana kufamba.

Rectangular shinda: Zino rayo chimiro chakaenzana, uye zino kona yakaenzana ne0 madhigirii. Iyo ine yakanyanya kutapurirana kunyatsoita, asi yakaderera centering kunyatsoita uye isina simba midzi simba.

Serrated thread: Zino rayo chimiro chimiro chisina kuenzana chetrapezoidal, ine zino flank angle ye 3 degrees panzvimbo yekushanda. Mudzi weshinda yekunze ine kona yakakura yakatenderedzwa, uye kufambisa kwekufambisa uye kusimba kwakakwirira kudarika iyo ye trapezoidal threads.

Mukuwedzera, kune dzimwe tambo dzakagadzirwa dzakakosha, dzakadai seV-shaped threads, Whitney threads, tambo dzakatenderera, nezvimwewo. Aya ma profiles ane maitiro avo uye anosarudzwa uye anoshandiswa maererano nemhando dzakasiyana dzemashandisirwo.
