Bhaudhi simba kirasi: chokuguma, GOST uye torque

Mukurima yanhasi anoshandisa muzvizhinji pamusoro STRUCTURAL okunze, chimwe nechimwe anoita chokupedzisira chigadzirwa chairo basa, kazhinji kukosha kwazvo. Saka, mumwe zvinangwa pamasikiro uye anogadzira zvinhu kunzwisisa zvinoumba zvivako anova zvakavimbika kutara pakati penhindi.

Chinangwa kushandisa bhaudhi

Pane zvakawanda zvaunogona kubatanidza zvinhu zviviri, akadai nomoto, pokunamatidza chokuedza, kushandiswa rivets. Zvisinei, vane imwe zvakafanana uye chaizvo zvinonyatsooneka drawback - ivo chimwe-chimedu. More chaizvo, kupatsanurwa, zvisinei, kuti dzakasiyana kuti deform kwavari, zvidimure uye zvichingodaro.

Zviri nyore zvikuru kuti kushandisa somunhu fastener wakakodzera, kunhonga pre-kirasi zvechizarira simba zvichienderana mutoro zvinoisa peungano.

The shinda inoshandiswa inenge zvose hurongwa kuti zvishoma kupfuura kuoma munhuwo yetea. Fungidzira motokari kuti hapana Cog. Saka kuti pane motokari - ari chitoyi chomwana, simba neboka mamiriro riri nechepazasi zvikuru, harusati kuita pasina Threaded zvinhu.

Zvakanakira ari Threaded kubatana

Pasinei chokwadi kuti dzimwe nguva mumwe torque guru haibvumiri imwe nguva kusununguka sunungura nati, bhaudhi, achine dzinoverengeka zvakanakira pamusoro dzimwe fastening nzira:

1. High kubatana kuvimbwa, pakawanda kwaipa Profile arşive kana mumwe shinda. Profile dzakabudirira kuvonga zvidzidzo zvakawanda, nokuti kukunda mitoro inorema uye kunodzivirirwa kusazvidzora (kunyange zvazvo achava kusarudza zvakarurama tightening torque).
2. Shungu ungano uye disassembly pezvivako. Inoshandiswawo kushandiswa rakabatana basa mudziyo - anokosha zvipanera, zvisina Somuenzaniso, welded kana riveted kubatana.
3. Kugona guru axial uye transverse zvinorema. bhaudhi simba rinowanikwa mune zvose longitudinal uye transverse negwara. Modern zvinhu uye ruzivo kuti tikwanise kuderedza uwandu fasteners akashandiswa uye kuderedza saizi yaro.
4. Low mutengo, kunyanya kana zvichienzaniswa mari kutenga nomoto zvinhu uye mabasa.

Pakati yeimwe zvausingagoni - kunetseka wevasungwa iri shinda mudzi. Naizvozvo, nokuti imwe mhando kuvakwa kunofanira kusarudzwa kirasi zvechizarira simba zvakarurama maererano kuiswa mutoro. Uyewo, kuti tibu- rakavimbika Threaded kubatana zvakakodzera kuyeuka kushandisa nokukiya zvinoreva, zvakadai chitubu the washers kana zvechizarira nzungu.

Mhando Threaded kwokubatana

Kuti sikuruwa kubatana, ipapo vanofanira kuita chimwe chidimbu rekambani shinda, uye wechipiri - panze. Mhando nhatu anogona kushandiswa zvichienderana magadzirirwo zvinhu:

1. Screw kubatanidza. Panyaya iyi, basa nzungu (chikamu chete munyika shinda) anoita chikamu nzvimbo. Rinotanga akachera gomba. A shinda ari ipapo rikashandiswa. Nokuti mamwe mashoko rinoshandisirwa ane mvere dzeraundi buri, pashure iyo sikuruwa iri kudhonzwa.

2. bhaudhi. Pano, zvose zviri nyore uye zvikuru yakavimbika: maviri kunofambidzana zvikamu kumeso akachera maburi vari akaiswa mumba bhaudhi, uye pamusoro neizvi divi - ari mupengo.

3. panhengo, mumwe mugumo iyo Volt kupinda chinhu raiva pedyo nebundu, uye wechipiri - the nati iri Volt.

Bhaudhi simba kirasi

Sezvataurwa pamusoro apa, mashoko fasteners anofanira vachiwirirana pavakapfimbana. Hapana pfungwa pane kwakajairika puranga Racks basa maturusi kushandisa zvikamu Stainless simbi. Panguva iyoyowo, mune dzimwe flange kwokubatana (semuenzaniso, tightening zvinoumba ari multi-tani kwakaita sesimbi hurongwa) nayo kunodiwa kushandisa zvinhu paine zvemaziso maitiro.

Kazhinji, boka bhaudhi simba (GOST 1759.4-87) - iri kutaridza zvemaziso zvatariswa, izvo zvinosanganisirawo kwekanguva nemishonga, nesimba muganhu, kuti hama kukosha elongation pashure nokutyora, neukukutu acho, uye mune zvimwe zviitiko kunyange kuoma. Kazhinji, izvi parameter rokuti kushandisa nhamba mbiri dzakaparadzaniswa kwenguva. Wokutanga vavo, pashure chokuwanziridza kubudikidza 10 inoratidza nguva risingamboshandisi nemishonga, uye wechipiri, uyewo yakawedzera ne10 nguva, inoratidza nhamba yaunganidzwa kugovera goho simba kwemashoko ari tensile simba. The yemudzimu chete manhamba maviri aya anoratidza kukosha shoma zvibereko simba. The kirasi zvechizarira simba iri mubhuku Kunyora yayo, riri sezvinotevera: M12h1,25h60.58 apo 58 - zvakafanana maviri-digit nhamba.

tightening

Kuti makachengeteka abate sikuruwa kubatana zvezvidzidzo kuvakwa, vanofanira kunyatsoongorora kuti kuedza (nguva) tightening. Saka, fungidzira mamiriro ezvinhu umo ruzivo "makanika" kokutanga kuwa pasi Hood renyu itsva motokari uye kuedza napo kuti chinosimudzira mupengo kana sikuruu. izvi zvose zvinogona Muchiitiko chokutanga, chete dzamira kushanda pamwe mbezo, uye yechipiri - kuburikidza drilling buri Hull. Izvi imhaka zvisiri akasarudzwa torque. Akanzwawo motokari Vanamakanika, vashandi uye akarurama vane "akavaka-muruoko" dynamometer. Asi mutsva zviri nani kushandisa imwe torque chipanera kana mhepo kunokanganisa zvipanera, izvo zvirire chairo torque.

Sei sunungura "kunzwisisa" bhaudhi

Ngatitii sungisa zvose zvaitika. Asi nguva inopfuura, uye unofanira sunungura fasteners zvakare. Nokuda ngura kuti dzimwe nguva zvisiri nyore chaizvo, uye mukuru-kirasi simba zvechizarira haiponesi kubva pakuparadzwa. Saka munofanira kuyeuka zvishomanana nzira kuti zviite kuti unwinding:

1. Kutanga, unofanira kushandisa "VeDeshkoy". Kuronga urwa zvakaturikidzaniswa kuti ngura.

2. Kumora vawane mashoko nati pamwe nenyundo kuputsa ngura iri shinda profile.

3. Unogona kuedza crank mumwe madhigirii shoma nenzira tightening ari nati uye ipapo unscrewed.

Zvakakosha kwete kumhanya, sezvo vanowanzova kugara nati kana sikuruwa musoro iri kiyi.
