Chishandiso chevhiri rekumashure chemotokari chakagadzirwa nei?
Zvishandiso zvemabheringi evhiri rekumashure emotokari zvinowanzova simbi ine chromium yakawanda (yakadai seGCr15), iyo ine kuomarara kwakanyanya (58-65HRC) uye inodzivirira kupera, uye yakakodzera kugadzirwa kwemabheringi evhiri rekumashure emotokari echinyakare.
Kusarudzwa kwezvinhu mumamiriro ekushanda akakosha
Munzvimbo dzine tembiricha yakakwira kana kuti dzine ngura, zvinhu zvinotevera zvinogona kushandiswa:
Youdaoplaceholder0 Mamiriro ekushanda anopisa zvakanyanya: Kana tembiricha yadarika 180℃, ma alloys ane cobalt, ma alloys ane chromium kana ma alloys ane molybdenum anofanira kushandiswa.
Youdaoplaceholder0 Nzvimbo ine ngura: Shandisa simbi isina ngura ine martensitic (inodzivirira ngura uye ine kuomarara kwakanyanya) kana simbi isina ngura ine austenitic (ine ngura iri nani).
Maitiro ekugadzira echinyakare
Mabheyaringi evhiri rekumashure emotokari dzechinyakare anowanzo shanda pamwe chete nemabheyaringi eroller ane mitsara miviri kana mabheyaringi ebhora. Kuiswa kwawo, kuomeswa, kuvharwa uye kugadziriswa kwekubvisa zvese zvinopedzwa pamutsetse wekugadzira mota.
Mhete yekuisa chisimbiso inoshanda zvakanyanya
Nekuda kwekuti ma "hub bearing" ari pedyo nepasi uye zvikamu zvakaita sema "brake discs" ane tembiricha yakakwira, anofanirwa kuchinjika kumamiriro akasiyana-siyana emugwagwa akaomarara uye nzvimbo dzakaoma dzekutyaira. Nokudaro, rin'i ye "bearing sealing" inofanira kunge iine simba rakanaka rekudzivirira kudonha kwemafuta, uye panguva imwe chete, inofanirawo kuva nesimba rakanaka rekudzivirira kupisa, matope uye tsvina.
Tekinoroji yekumonera
Mabheya ehub echizvarwa chechitatu anowanzo shandisa tekinoroji yekumonera kuti azvivharire ega hafu yemukati memhete. Kana tekinoroji yekumonera ichishandiswa, mutoro weaxial unokonzera kushanduka kwepurasitiki pamugumo wemhete huru yehub, nokudaro zvichibatanidza mhete huru yehub nemhete yemukati yehafu sechinhu chimwe chete. Zvichienzaniswa nekuchengetedza nzungu kwechinyakare, mhete yehub yechizvarwa chechitatu inoshandisa tekinoroji yekumonera inobatsira kuderedza vhoriyamu nehuremu, kuderedza mitengo, uye kuvandudza kuvimbika kwemhete yehub. Panguva imwe chete, pakuibatanidza mumota, danho rekugadzirisa nzvimbo dzezvikamu zvemukati rinobviswa.
Huremu hwakareruka uye hwakapfava
Pakugadzira chimiro chemabearings ehub echizvarwa chechipiri nechechitatu, ongororo yechinhu chakaganhurirwa inofanira kuitwa kuti ive nechokwadi chekuti flange ine kuomarara kwakakwana uku ichideredza vhoriyamu nehuremu hwayo zvakanyanya sezvinobvira. Pakati pazvo, kuomarara kwebearings yehub yechizvarwa chechitatu kunoreva kutsveyama kweAngle yehub flange kana tichienzanisa neflange yekunze yering. Huremu hweaxle hunoderedzwa kuburikidza nekugadzirwa kwakabatanidzwa uye kwakapfava. Bearings yehub yechizvarwa chechipiri yakareruka 180g pane yechizvarwa chekutanga, uye bearings yehub yechizvarwa chechitatu inoderedza huremu ne120g.
Torque yakaderera yekukweshana
Chinhu chakakosha chekuderedza kushandiswa kwemafuta mumotokari ndechekugadzira ma hub bearing ane low friction torque. Zvinhu zvikuru zvinokanganisa friction torque yema bearing imhando yema bearing uye preload. Kuvharwa kwema bearing kunokonzera chikamu chikuru che friction torque components. Nokudaro, kuvandudza dhizaini ye sealing kuderedza friction torque kunogona kuwedzera zvakanyanya mashandiro ema hub bearing. Ma Hub bearing akashanduka kubva kuchizvarwa chekutanga kusvika kuchizvarwa chechina chekupedzisira, ne frictional torque ichiderera zvakanyanya uye zvishoma nezvishoma.
Tekinoroji yeABS
ABS mudziyo wekudzora kuchengetedzeka kwemotokari une zvakanakira zvakaita sekudzivirira kutsvedza uye kudzivirira kukiya. Kana mota ikabhureka kamwe kamwe, inogadzirisa otomatiki simba rebhureka nekuona kumhanya kwevhiri kudzivirira mavhiri kuti asavharwe uye kupfupisa daro rebhureka. Kuonekwa kwekumhanya kwekutenderera kunoitwa nemasensa emagineti akaiswa pazvikamu zvinotenderera nemavhiri uye zviri pedyo zvakasungirirwa pamuviri wemotokari. Kune mhando mbiri dzemasensa emahub ane masensa eABS: imwe inoiswa mukati mehub, nepo masensa akaiswa pane zvimwe zvikamu; Imwe mhando inoiswa mukati mehub pamwe chete nesensa (inonzi hub unit ine sensor).
Mabearing ehub akasakara kana akakuvara kana mayuniti ehub anogona kukonzera kutadza kushanda zvakanaka uye kunodhura kwemotokari yako panguva yekutyaira, uye kutokonzera njodzi kuchengetedzeka kwako. Ndapota teerera zvinhu zvinotevera pakushandisa nekuisa mabearing ehub:
Kuti uve nechokwadi chekuchengetedzeka uye kuvimbika zvakanyanya, zvinokurudzirwa kuti ugare uchiongorora ma hub bearingers pasinei nezera remotokari - teerera zviratidzo zvekunyevera kwekutanga kwekunge ma bearingers apera: kusanganisira chero ruzha rwekukweshana panguva yekutenderera kana kudzika kwesimba kwemavhiri ekubatanidza masuspension paanenge achitenderera.
Kune mota dzinotyaira nemavhiri ekumashure, zvinokurudzirwa kuti mabheringi emberi ehub apiswe mafuta kana mota yafamba makiromita zviuru makumi matatu nemasere (38,000). Pakutsiva sisitimu yekubhureka, tarisa mabheringi uye tsiva mafuta ekuvhara.
Kana ukanzwa ruzha rusina kujairika ruchibva munzvimbo yehub bearing, chinhu chekutanga uye chakakosha ndechekutsvaga nzvimbo inoitikira ruzha. Kune zvikamu zvakawanda zvinofamba zvinogona kuburitsa ruzha, kana kuti zvimwe zvikamu zvinotenderera zvakasangana nezvikamu zvisingatenderere. Kana zvikaonekwa kuti ruzha rwacho rwunobva kuberearing, bearing inogona kunge yakakuvara uye inoda kutsiviwa.
Nekuti mamiriro ekushanda anokonzera kutadza kwemabheringi kumativi ese nekuda kwehubhu revhiri repamberi akafanana, zvinokurudzirwa kuti atsiviwe ari maviri kunyangwe kana bearing imwe chete yakakuvara.
Mabearing eHub anonyanya kugadzikana, uye chero zvodini, nzira dzakakodzera nezvishandiso zvakakodzera zvinofanirwa kushandiswa. Panguva yekuchengetera, kutakurwa uye kuiswa, zvikamu zvebearing hazvifanirwe kukuvara. Mamwe mabearing anoda kumanikidzwa kwakanyanya kuti apinzwe mukati, saka maturusi akakosha anodiwa. Iva nechokwadi chekutarisa bhuku rekugadzira mota.
Pakuisa mabheringi, anofanirwa kuitwa munzvimbo yakachena uye yakarongeka. Zvidimbu zvidiki zvinopinda mumabheringi zvichapfupisawo hupenyu hwazvo hwekushanda. Zvakakosha kuchengetedza nzvimbo yakachena pakutsiva mabheringi. Hazvibvumirwi kurova bearing nenyundo. Chenjerera kuti usadonhedze bearing pasi (kana kuibata zvisina kunaka nenzira yakafanana). Usati waisa, mamiriro emubato neimba yemabheringi zvinofanirawo kuongororwa. Kunyangwe kusakara kudiki kunogona kukonzera kusakwana zvakanaka, nokudaro zvichikonzera kutadza kushanda kwebearing nguva isati yakwana.
Kune mayuniti ekubata mahub, musaedza kupatsanura mahub bearing kana kugadzirisa ma sealing rings emahub units; zvikasadaro, ma sealing rings anogona kukuvara, zvichiita kuti mvura kana guruva zvipinde. Kunyangwe nzira dzemujaho dze sealing ring ne inner ring zvakakuvara, zvichikonzera kuti bearing isashande zvachose.
Kune ring yemagnetic thrust mukati me sealing ring yebearing ine mudziyo weABS. Iyi thrust ring haifanirwe kurovera, kupwanywa kana kusangana nemamwe masimba emagineti. Usati waisa, ibvise mubhokisi rekurongedza uye ichengetedze kure nemasimba emagineti, akadai semagetsi emagetsi kana maturusi emagetsi ari kushandiswa, nezvimwewo. Paunenge uchiisa mabearing aya, tarisa ABS alarm netender iri padashboard kuburikidza nekuyedzwa kwemamiriro emugwagwa kuti ugadzirise mashandiro emabearing.
Kune ma hub bearing ane ABS magnetic thrust rings, kuti uone kuti thrust ring yakaiswa padivi ripi, unogona kuunza chinhu chidiki uye chakareruka pedyo nemucheto webearing. Simba remagineti rinogadzirwa nebearing richaikwezva. Pakuisa, tarisa divi rine magnetic thrust ring mukati, wakatarisana zvakananga nezvikamu zvinonzwa zveABS. Kusaisa zvakanaka kunogona kutungamira kukundikana kwebasa remabhureki.
Mabheyaringi mazhinji akavharwa uye haadi mafuta muhupenyu hwawo hwese hwekushanda. Mamwe mabheyaringi asina kuvharwa, akadai semabheyaringi ane tambo mbiri, anofanira kuzorwa mafuta panguva yekuisa. Nekuda kwehukuru hwakasiyana hwemukati memabheyaringi, zvakaoma kuziva kuti grisi yakawanda sei yekuwedzera. Chinhu chakakosha ndechekuona kuti mune mafuta mumabheyaringi. Kana paine mafuta akawandisa, kana mabheyaringi achitenderera, mafuta akawandisa achabuda. Ruzivo rwese: Panguva yekuisa, huwandu hwemafuta hunofanirwa kuita 50% yenzvimbo yekuisa.
Pakuisa ma lock nuts, hukuru hwe torque hunosiyana zvikuru nekuda kwekusiyana kwemhando dzema bearing uye ma bearing housings. Ndapota tarisai mirairo yakakodzera.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
