Kune akawanda akasenderedzwa-akavharidzirwa matemba echiridzwa kana gudzazwi gungano munzvimbo dzebazi. Iyo semi-yakavharirwa dzimba chikamu chegudzazwi inoratidzwa muMufananidzo 1, ine zvinhu zviri 3A21 ngura isina aruminiyamu ndiro, ukobvu hwezvinhu t = 2mm, uye chimiro chikuru chakaenzana. Kubva pane akakodzera mativi echokwadi zvinodiwa zvemufananidzo, zvinogona kuoneka kuti chimiro chechikamu, iro remukati mhango uye zvimiro zvekumisikidza zvegomba hazvidiwe kuti zvive zvepamusoro pakururama, kusvika IT10 nhanho, uye yemukati yekukotamisa radius R chechikamu chacho chiri 2mm, uye kuonda kwenzvimbo kwechinhu kwacho kunotenderwa kuve 30%.


Mufananidzo 1 semi-yakavharwa shell zvikamu

Kubva pachikamu chechikamu, goko iri mativi mashanu akanyatsovharirwa, rutivi rwechitanhatu haruna kuvhurika semi-yakavharirwa chimiro, mushure mekupedzwa kwekutanga kukotama, asiwo rutivi rwechitanhatu rwechimiro kukotama (ona Mufananidzo 2). Kubva vakakotama kukura ari Figure 1, wekutanga vakakotamisa haana kunyanya kuoma kuumba, asi wechipiri vakakotamiswa flange chikamu kukura iduku uye pane dambudziko kuti chakuvhuvhu haagoni kusunungurwa pashure vakakotama. Uye zvakare, chikamu chinoda yakawanda yekugadzirisa maburi mushure mekukombama kwapera, saka saizi yechimiro chekukotama chinofanira kuvimbiswa. Yechipiri kukotama paH / D â ˆ 1.5 (uko H ndiko kukotama kukwirira, kungangoita 6mm; D ndiko kukombama dhayamita, inenge 4mm), iyo flange inokombama yakanyanya kuoma, kunyanya iyo flange nharaunda uye flange kukwirira kwakafanana, kugadzira chimiro pakuumba kuri nyore kuburitsa kudhonza kutsemuka, saka maitiro anodikanwa anofanira kuitwa. Panguva imwecheteyo, nekuti iyo yekumusoro chikamu uye padyo kurudyi kona yakakotama inoumba chikamu ipfupi, uye rimwe divi rakavhurika, saka simba rayo rinobatirira rinoshandiswa pane rakapetwa katatu harisi hombe, ndiko kuti, zvinhu zvakawandisa muchikamu chakatenderedzwa haina kunyatsoenderana nechena radial kuyerera mukukonana. Pane zvinopesana, nekuda kwekushaikwa kwezvinhu zvinodzikisira munzira yekutsika, izvo zvinhu zvinoyerera zvakanyanya munzira yekuyambuka, saka inovandudza zvakanyanya kushanduka kwezvinhu uye inoita kuti iumbwe mune imwe mbama.

(1) Maitiro ekuyerera Iyo huru yekugadzirisa kuyerera kwegobvu inoratidzwa muTafura 1. gumi maitiro anobatanidzwa mukugadziriswa kwegobvu, pakati peiyo nzira huru yekugadzira ndeyekucheka kwetambo uye maitiro maviri ekukotama. Sezvo chikamu ichi chiri chikamu chakaenzana, chimiro mushure mekupetenuka hachina kuomarara, saka chimiro hachishandiswi nedonhwe kufa, asi zvakanyanya netambo yekucheka uye nemakemikari etching, iyo inogona kuvimbisa kugadzirisa kwakaringana uye simba rezvinhu kumucheto . Mushure mekupedzisa chakapetenuka chimiro, mabhendi maviri anodikanwa, uye kune mativi matatu kuti akotamiswe. Iyo yekutanga bend inopedzisa kukotama kwemativi mana akareba echikamu, uye chikamu chinoratidzwa muMufananidzo 3 mushure mekukotama nekugadzira; chikamu chechipiri chakakotama chikamu chakavharwa kumusoro, uye chikamu chinoratidzwa muMufananidzo 4 mushure mekukotama kwapera.

Shell mukupedzisa kwekutanga kukotama kunotungamira mukusagadzikana kusagadzikana nekuda kwekushanduka, chikamu chechipiri chakavharwa chebhendi chichaunza dambudziko rekumisa kutsauka. Asati uye mushure mekupedzwa kwekukotama, goko rinogadziriswa nemakomba akaenzana uye maburi anokwira, ayo anoda kuiswa nechimiro. Naizvozvo, mushure mekutanga kukotama, weld kugadzira uye weld bundu kubvisa, zvakafanira kuronga chakuumba chekuumba. Huwandu hwemaseti matatu efa anodikanwa kuti agadzirise makomba, kuwedzera kwekutanga uye kwechipiri kukotama kunofa uye kuumbwa kunotevera kunofa, kuti uwane kutsikisa kwakazara uye kuumba.

(2) Shell inovhurika isina chinhu chimiro uye kukura kwehukuru Sezvo ganda rinoda kukombama kaviri, sechivimbiso chekutanga chekukombama kwemahombekombe, kuverenga kwakaringana kwehukuru hwacho hunokosha kwakakosha, saka chikamu chechipiri chakakotama chikamu chinofanira kutorwa account. Mushure mekuona chisina kuvhurika chisina kuvharwa chimiro, shandisa fomula kuti uverenge saizi chimiro, kana zvichidikanwa, unogona kuona yekupedzisira akaziviswa saizi nekuyedza kukotamisa nzira.

Chimiro chekupedzisira chinonzwisisika, kukotama kwayo kuita chikamu zvinoenderana neyekuverenga nzira yezvakajairika kukotama zvikamu zvisina kusimira saizi inogona kuverengerwa chikamu ichi chakakotama kona iri 90 °, isina chinhu uye inovhura hurefu hwe.

Iko, L ihurefu hwese hweisina chinhu (mm); l 1, l 2 yeiyo yakatwasuka kumucheto kureba (mm); R yeiyo yakakombama nharaunda (mm); x yeiyo isina kwayakaenzana dura rekumisikidza inokwana, maererano ne Tafura 2; t yeukobvu hwesina chinhu (mm).

Tafura 2 isina kwayakarerekera dura rekushandura coefficient x kukosha


Ukobvu hweshell chikamu t = 2mm, kukombama radius r = 2mm, saka iyo yekusarerekera nhepfenyuro yekumisidzana coefficient x = 0.32, zvinoenderana neyeganda chigadzirwa dhizaini uye irikufumurwa dhayagiramu, iyo inowonekera urefu hwechikamu chimwe nechimwe chinoverengerwa. Uye zvakare, maererano nesheet simbi yekukotamisa zvinodiwa, iyo gomba gomba 4 × Ï † 1.5mm rakagadzirwa muchikamu umo mativi mana anofanira kukotama, uye yekupedzisira inoitika dhayagiramu inoratidzwa muMufananidzo 5.
