1, kushandiswa kweshinda uye maitiro

Kushandiswa kweshinda kwakakura kwazvo, kubva kundege, mota kusvika kuhupenyu hwedu hwezuva nezuva mukushandiswa kwepombi dzemvura, gasi uye zvichingodaro zvinoshandiswa munhamba yakawanda yezviitiko, yakawanda yeshinda inotamba yakasimba yekubatanidza basa, yechipiri ndeye kuendeswa kwesimba uye kufamba, kune chimwe chinangwa chakakosha chetambo, kunyange zvakasiyana-siyana, asi nhamba yavo ishoma.

Nekuda kwechimiro chayo chakareruka, kuita kwakavimbika, nyore disassembly uye kugadzirwa kuri nyore, shinda yave chinhu chakakosha chechimiro mumhando dzese dzemakanika uye zvigadzirwa zvemagetsi.

Zvinoenderana nekushandiswa kweshinda, marudzi ese ezvikamu zvakarukwa anofanira kunge aine maviri anotevera mabasa ekutanga: imwe yakanaka convergence, imwe yakakwana simba.

2. Thread classification

A. zvinoenderana nemaitiro avo uye mashandisiro, anogona kupatsanurwa muzvikamu zvina zvakafara:

Ordinary thread(fastening thread) : zino shape is triangular, rinoshandiswa kubatanidza kana kusungirira zvikamu.Tambo yakajairika inopatsanurwa kuita shinda yakaoma uye shinda yakanaka zvichienderana nenamo, kusimba kwekubatanidza kweshinda yakatsetseka kwakakwira.

Transmission thread: zino shape ine trapezoid, rectangle, saw shape uye triangle, nezvimwewo.

Kuisa chisimbiso: yekubatanidza chisimbiso, kunyanya pombi tambo, taper tambo uye taper pombi tambo.

shinda yakakosha, inodaidzwa seshinda yakakosha.

B, maererano nenharaunda (nyika) inogona kukamurwa kuva: metric thread (metric thread) thread, n thread, etc. . , dhayamita nenamo uye mamwe ane hukama tambo paramita anoshandiswa inch saizi (inch) .Munyika yedu, kona yezino yakabatana kusvika 60 ° , uye dhayamita uye pitch series mu millimeter (mm) inoshandiswa kutumidza rudzi urwu rweshinda: tambo yakajairika.

3. Common thread type

4.Basic terminology yeshinda

Thread: pamusoro pe cylindrical kana conical surface, fungidziro inopfuurira inoumbwa pamwe chete nemutsara we spiral ine chimiro chezino chakatsanangurwa.

External thread: shinda inoumbwa pamusoro pehumburumbira kana koni.

nternal thread: shinda yemukati inoumbwa pamusoro pehumburumbira kana koni.

Diameter: dhayamita yehumburumbira yekufungidzira kana koni tangent kusvika kukorona yeshinda yekunze kana hwaro hweshinda yemukati.

Diameter: dhayamita yehumburumbira yekufungidzira kana koni tangent kusvika pazasi peshinda yekunze kana korona yeshinda yemukati.

Meridian: dhayamita yehumburumbira yekufungidzira kana koni ine jenaretisi inopfuura nemumikoto uye mapurojekiti ehupamhi hwakaenzana.Iri humburumbira kana koni yekufungidzira inonzi silinda yepakati nepakati kana koni.

Shinda yekurudyi: shinda inopinzwa mukati ichitenderedzwa newachi.

Shinda yekuruboshwe: shinda inotenderedzwa kana yatenderedzwa neruboshwe.

Zino angle: mushinda mazino mhando, maviri akatarisana zino divi kona.

Pitch: chinhambwe cheaxial pakati pemazino maviri ari padyo pamutsetse wepakati unoenderana nemapoinzi maviri.

5. Thread marking

Metric thread yekumaka:

Kazhinji, metric tambo yekumaka izere inofanira kusanganisira zvinotevera zvinhu zvitatu:

A inomiririra shinda yemhando kodhi yehunhu hweshinda;

B shinda saizi: kazhinji inofanira kuumbwa nedhayamita nenamo, kune akawanda-tambo shinda, inofanirawo kusanganisira inotungamira uye mutsara nhamba;

C shinda chaiyo: iko kurongeka kwetambo zhinji nedhayamita yenzvimbo yekushivirira (kusanganisira nzvimbo yekushivirira nzvimbo uye saizi) uye kureba kwechisarudzo chakabatanidzwa.
