Ruzivo rwekutanga rwekutakura

Sechikamu chakakosha chemichina yemazuva ano, mabheyaringi anoshandiswa zvakanyanya. Tese tinoziva uye tinoziva zvishoma nezvawo.

MabheyaringiKazhinji zvinosanganisira mhete yemukati, mhete yekunze, zvinhu zvinokungurutsa uye keji. Kune mabheringi akavharwa, wedzera mafuta nezvisimbiso (kana nhoo). Ndizvo zvinoreva mabheringi.

Zvichienderana nemamiriro ekushanda kwebheyaringi, mhando dzakasiyana dzemabheyaringi dzinogona kusarudzwa kuti dziite basa rebheyaringi zviri nani uye dziwedzere hupenyu hwebheyaringi. Tinofanira kufunga nezvezvinhu zvinotevera pakusarudza mabheyaringi:

Mutoro we radial

Mutoro weAxial

Zvinodiwa zveRPM

Kuyerera kwemagetsi

Kumhanya kweAxial

Tembiricha yekushanda

Zvinodiwa paruzha

Mamiriro ekuzora mafuta

 

Modhi yebheari inowanzova nekodhi yekutanga, kodhi yekutanga uye kodhi yepositi. Kazhinji, chiratidzo chebheari chinongoratidzwa nechiratidzo chekutanga. Modhi yekutanga inowanzova nezvikamu zvitatu, kodhi yemhando, kodhi yehukuru uye kodhi yedhayamita yemukati. Post-code ndeyekushandisa mavara nenhamba kuratidza chimiro, kushivirira uye zvinodiwa zvakakosha zvezvinhu. Kodhi yekutanga inoshandiswa kuratidza zvikamu zvidiki zvebheari, izvo zvinoratidzwa nemavara.

 

1. Zita rekutanga rekodhi

Kodhi yekutanga inoshandiswa kuratidza dhayamita yemukati, dhayamita yakatevedzana, dhayamita yakatevedzana uye rudzi rwebheyaringi, kazhinji kusvika kumadijiti mashanu, seizvi:

1) Dhayamita yemukati yebheyaringi inoratidzwa nenhamba yekutanga kubva kurudyi rwekodhi yekutanga.

Dhayamita yemukati yebheya ine dhayamita yemukati yakafanana ye d=20~480mm inowanzova multiple ye5, uye aya manhamba maviri anomiririra quotient yehukuru hwedhayamita yemukati yebheya yakakamurwa ne5, senge 04 means d=20mm; 12 means d=60mm zvichingodaro. Kune mabheya ane dhayamita yemukati ye10mm, 12mm, 15mm uye 17mm, makodhi edhayamita yemukati ndeaya 00, 01, 02 uye 03 zvichiteerana. Kune mabheya ane dhayamita yemukati iri pasi pe10mm uye anopfuura 500mm, nzira yekumiririra dhayamita yemukati yakatsanangurwa neimwe nzira, ndapota tarisai GB/T272-93.

 

2) Rutivi rwedhayamita yebheyaringi (kureva, rutevedzero rwekuchinja kwedhayamita yekunze nehupamhi hwebheyaringi ine chimiro chakafanana uye dhayamita yemukati yakafanana) inoratidzwa nenhamba yechitatu kubva kurudyi rwekodhi yekutanga.

Semuenzaniso, kune ma radial bearings uye radial thrust bearings, 0 na 1 zvinoratidza extra light series; 2 inoratidza light series; 3 inoratidza medium series; 4 inoratidza heavy series. Kuenzanisa saizi pakati pe series kunoratidzwa mumufananidzo uri pazasi. Kunze kwe extra-light series ne 1, thrust bearing inoenderana nekutaura kwe radial bearing.

3) Nhevedzano yehupamhi hwebheyaringi (kureva, nhevedzano yekuchinja muhupamhi hwebheyaringi ine chimiro chakafanana, dhayamita yemukati uye nhevedzano yedhayamita) inoratidzwa nenhamba yechina kubva kurudyi rwekodhi yekutanga.

Kana kuenzanisa kwedhayamita series ye width series yeMufananidzo 13-4 kwakanyorwa se 0 series (normal series), width series code O haigone kunyorwa mukodhi yemabearings mazhinji, asi kune spherical roller bearings nema tapered roller bearings, width series code 0 inofanira kunyorwa. Diameter series codes nema width series codes pamwe chete anonzi dimension series codes.

 

4) Kodhi yemhando yebheari inomiririrwa nenhamba yechishanu kubva kurudyi rwekodhi yekutanga (yemabheyaringi ecylindrical roller uye mabheyaringi eneedle roller, kodhi yacho ibhii).

 

2. Kodhi yepositi

Post-code yebearing ndeyekushandisa mabhii nenhamba kuratidza chimiro, kushivirira uye zvinodiwa zvakakosha zvechinhu chacho. Kune zvakawanda zviri mupost-code, uye heano mamwe mazita emakodhi anowanzoshandiswa.

1) Kodhi yemukati mechimiro ndeyekuratidza chimiro chemukati chakasiyana chemhando imwe chete yebheyaringi, iyo inoratidzwa nemabhii anoteverwa nekodhi yekutanga. Semuenzaniso, mabheyaringi ebhora rekubatana ane makona ekubatana e15°, 25° uye 40° anomiririrwa neC, AC naB zvichiteerana kuratidza musiyano wechimiro chemukati.

2) Giredhi rekutsungirira rebearing rakakamurwa kuita magiredhi maviri, magiredhi mana, magiredhi mashanu, magiredhi matanhatu, magiredhi matanhatu uye magiredhi 0, ese ari magiredhi matanhatu, kubva pakakwirira kusvika pakaderera, uye makodhi avo ndeaya /PZ, /P4, /PS, /P6, /P6X uye /PO. Pakati pemakirasi ekutsungirira, kirasi 6X inoshanda chete kumabheringi eroller akapfava; Giredhi 0 igiredhi rakajairika, risina kunyorwa mukodhi yebheringi yevhiri.

3) Mabheari anoshandiswa zvakanyanya akakamurwa kuita boka rimwe, mapoka maviri, mapoka 0, mapoka matatu, mapoka mana uye mapoka mashanu, ese ari mapoka matanhatu, uye clearance ye radial inobva padiki kusvika pakuru. Cleaning yeboka o iboka rinowanzoshandiswa, risina kunyorwa mu bearing code, uye mamwe mapoka e clearance anomiririrwa ne /CI, /CZ, /C3, /C4 uye /CS mu bearing code.

 

3. Kodhi yekare

Chinyorwa chekutanga chebheya chinoshandiswa kuratidza zvikamu zvidiki zvebheya, izvo zvinoratidzwa nemabhii. Semuenzaniso, L inoshandiswa kumiririra rin'i inoparadzaniswa yebheya inoparadzaniswa; K inomiririra zvinhu zvinotenderera uye zvikamu zvekeji zvebheya, nezvimwewo.

 

Kune mhando dzakawanda dzema "rolling bearings" mumashandisirwo anoshanda, uye ma "bearing codes" anoenderana nawo akaomarara. Kodhi yakataurwa pamusoro apa ndiyo inonyanya kushandiswa uye inonyanya kushandiswa mu "bearing code", uye unogona kuona nekutarisa "bearing" inowanzoshandiswa kana uchinyatsoziva chikamu ichi chekodhi. Kuti uwane nzira yakadzama ye "rolling bearings", ndapota tarisa GBT272.
