Kutumidzwa kwebheyaringi uye zvazvinoreva

 

Zvinokuberekamodhi inowedzera zvishoma nezvishoma zvichienderana nezvinodiwa nevanhu varipo, uye ikozvino network yagadzirwa zvikuru, kutapurirana kwemashoko kuri kukurumidzawo, uye zviri nyore kuziva modhi yebearing. Tevere, tichakuzivisai nezvekodhi yekutanga, post-code, pre-code nedzimwe ruzivo rwakabatana nezvebearing.

 

Kutakurakudomwa uye zvakunoreva

 

Iyokuberekamodhi inowanzova ne pre-code, basic code uye post-code. Kazhinji, bearing design inongoratidzwa ne basic design. Modhi yekutanga inowanzova nezvikamu zvitatu, type code, size code uye inner diameter code. Post-code ndeyekushandisa mabhii nenhamba kuratidza chimiro, tolerance uye zvinodiwa zvakakosha zvezvinhu. Prefix code inoshandiswa kuratidza zvikamu zvidiki zvebearing, izvo zvinoratidzwa nemavara.

 

Nzira yeKusarudza Bearing Yechinangwa Chakazara (Rolling Bearing)

 

Yakakamurwa kuita: pre-code, basic code uye post-code.

 

1. Zita rekutanga rekodhi

 

(Kodhi yerudzi, kodhi yehukuru, kodhi yedhayamita yemukati [manhamba maviri])

 

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 yebheyaringi ine dhayamita yemukati yakafanana ye d=20~480mm inowanzo kuve multiple ye5, uye aya manhamba maviri anomiririra quotient yehukuru hwedhayamita yemukati yebheyaringi yakakamurwa ne5, senge 04 means d=20mm; 12 means d=60mm, nezvimwewo. Kune mabheyaringi ane dhayamita yemukati ye10mm, 12mm, 15mm uye 17mm, makodhi edhayamita yemukati ndeaya 00, 01, 02 uye 03 zvichiteerana. Kune mabheyaringi ane dhayamita yemukati isingasviki 10mm uye inopfuura 500mm, nzira yekuratidza dhayamita yemukati yakatsanangurwa neimwe nzira, ndapota tarisai GB/T272-93.

 

2) Rutivi rwedhayamita yebheyaringi (kureva, rutivi rwekuchinja kwedhayamita yekunze nehupamhi hwebheyaringi ine chimiro chakafanana uye dhayamita yemukati yakafanana) runoratidzwa nenhamba yechitatu kubva kurudyi rwekodhi yekutanga. Semuenzaniso, kune mabheyaringi eradial neradial thrust, 0 na1 zvinoratidza rutivi rwekuwedzera rwechiedza; 2 inoratidza rutivi rwechiedza; 3 inoratidza rutivi rwepakati; 4 inoratidza rutivi runorema. Kuenzanisa kwehukuru pakati perutivi kunoratidzwa mumufananidzo uri pazasi. Mabheyaringi ethrust kunze kwe1 inomiririra rutivi rwechiedza, mamwe ese nemabheyaringi eradial akafanana.

 

3) Upamhi hwebearing (kureva, shanduko dzekuchinja kweupamhi hwebearing ine chimiro chakafanana, dhayamita yemukati uye dhayamita series) inoratidzwa nenhamba yechina kubva kurudyi rwekodhi yekutanga. Kana kuenzanisa kwedhayamita series yeupamhi muMufananidzo 13-4 kwakanyorwa se0 series (normal series), kodhi yeupamhi O haigone kunyorwa mukodhi yemabearing mazhinji, asi kune mabearing espherical roller uye mabearing etapered roller, kodhi yeupamhi series 0 inofanira kunyorwa.

 

Makodhi edhayamita akatevedzana uye makodhi edhayamita akatevedzana akafara pamwe chete anonzi makodhi edhayamita akatevedzana.

 

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 ndeanoti /PZ, /P4, /PS, /P6, /P6X uye /PO. Pakati pemakirasi ekutsungirira, kirasi 6X inoshanda chete kumabheringi eroller akapfava; Level 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" mukushandiswa kunoshanda, uye ma "bearing codes" anoenderana nawo akaomarara. Kodhi yakataurwa pamusoro apa ndiyo inonyanya kushandiswa uye inonyanya kushandiswa ye "bearing code", uye unogona kuona nekutarisa "bearing" inowanzoshandiswa kana uchinyatsoziva chikamu ichi chekodhi. Kuti uwane nzira yakadzama ye "rolling bearings", ndapota tarisa GBT272-93.
