Kuoma: Kugona kwechigadzirwa kupikisa zvinhu zvakaoma zvemunharaunda zvakatsikirirwa mukati maro chiratidzo chekushanda kuyera chiyero chekupfava uye kuoma kwezvinhu zvesimbi.Muedzo unoreva-kuoma bvunzo (Brinell, Rockwell, Vickers)Sample gadziriro yezvinodiwa: Iwo maviri magumo emuenzaniso anofanana, nzvimbo yacho yakati sandarara, uye hapana mafuta kana oksidhi inotenderwa.
Nzvimbo yekuedza 10 ~ 35 °
Mukuona kwekuoma kwebhoti, hapana kupisa kwekupisa kwemabhoti, kunongoda kuita kuoma kwepamusoro, mukati mehutano hwakakodzera pamutsara.Kana iri bhoti yekurapa kupisa, zvakakosha kutema kuoma pamusoro pehupamhi hwehupamhi pamagumo.Nzvimbo yekuedza inoratidzwa mumufananidzo.Muedzo wekuoma uri pa 1/2R pamusoro, uye kuoma kunosangana nechiyero.
Kuomarara kwebhoti kune nzvimbo uye musimboti, nzvimbo yacho inoreva kushandiswa kweVickers kana kuti Rockwell kuomarara mushure mekubvisa ngura yepasi, etc. Nheyo inofanira kunge iri mukubviswa kwemusoro 1/2 dhayamita yakareba chikamu chepamusoro nepakati. 1/2 nzvimbo yekutamba yakaoma, mutsauko pakati pehuviri hwekuoma haungapfuure 30HV, iyo nzvimbo yakakwira kupfuura 30HV inoratidza kuti iyo carburizing yepasi, haibvumirwe, Kana iyo nzvimbo yakaderera pane 30HV, zvinoreva kuti iyo nzvimbo yakasvibiswa. , uye hazvibvumirwi.
Iyo general 8-giredhi nati inofanirwa kurapwa kupisa, asi hapana inorapwa kupisa, iyo yakajairwa 8-giredhi nati inowanzogadzirwa nesimbi makumi matatu neshanu, iyo yekuomarara bvunzo inotsanangurwa zvakare, iyo general nzvimbo haidiwe, mugadziri wekupisa kupisa. inoedza kuomarara mushure mekupisa kupisa, metric nut inowanzotyoka kubva pakati kuti iedze kuoma kwemoyo wayo, iyo inch nut inowanzotyoka pane chimwe chezviso (kureva, kucheka mapanga maviri pamusoro), kuyedza kuomarara. yepakati pechikamu cheimwe nzvimbo, uye nzungu duku dzinowanzopfekedzwa kubva pachikamu 0.2 ~ Edza kuoma mushure me 0.3mm.4.6 ~ 6.8 mabhoti haadi kurapwa kwekupisa;Yakasungirirwa yemhando yepamusoro nut mhando 2.
Muyero wenyika GB3098.1 uye wepasi rose GB3098.3 unotaura kuti kuomarara kwekupokana kunoyerwa pa1/2 radius yechikamu chemuchinjikwa chechikamu.Muchiitiko chekukakavadzana chero panguva yekugamuchirwa, Vickers kuomarara kuchashandiswa seyedzo yekupokana.At least 3 kuverenga kunofanira kutorwa kune yega yega sampuli.
Arbitration bvunzo nzvimbo: Paunenge uchizivisa mhedzisiro yebvunzo pakati pemutengi nemutengesi nekuda kwekupokana, iyo bvunzo yekuomarara ichayerwa panzvimbo yepakati (r/2) yeradius yenzvimbo yakachekwa-yakadzikira imwe dhayamita kubva kumagumo. bhaudhi kana stud.Kana saizi yechigadzirwa ichibvumidza, tora kuverenga 4 pakupera kwebhaudhi iyi kana stud.Zvigadzirwa zvidiki zvedhayamita zvinogona zvakare kuyedzwa uchishandisa inofananidzira nzvimbo yebhaudhi yemusoro terminal inoenderana nepamusoro yakachekwa-yepamusoro nzvimbo.Pakuyedzwa kwechinyakare, kuoma kwemabhaudhi, screws kana matudhi anogona kuyedzwa kumusoro, muswe kana shank mushure mekubviswa kwakakodzera kwepasi.
Pamatanho ese, kana kukosha kwekuyedza kwakadarika muganho wepamusoro wekuomarara, mufananidzo unofanirwa kubviswa panzvimbo yedhayamita yezita kubva kumagumo emuenzaniso, uye pakati pemuenzaniso uye nzira yeshinda panzvimbo yepakati bvunzo, kukosha kwekudzokorora hakufanire kudarika muganhu wepamusoro wekuoma, kana pasina mubvunzo, iyo Vickers kuoma (HV) inofanira kugamuchirwa sechisarudzo.Muedzo wekuomarara kwepamusoro unogona kuwanikwa kumagumo kwechigadzirwa kana kumucheto kwehexagon, uye nzvimbo yekuyedza inofanirwa kuve yakaderedzwa pasi kana kukwenenzverwa kuti ive nechokwadi chekudzokorora kwebvunzo uye mamiriro echokwadi eiyo specimen surface.HV0.3 inoshandiswa muyedzo yekupokana yekuomarara kwepasi bvunzo.Kuoma kwepamusoro kwakaedzwa neHV0.3 kuchafananidzwa nehupamhi hwekuoma kwekuyera kukosha kwakaedzwawo neHVo.3, uye mutsauko haungapfuuri 30 HV kuoma kwehutano.Kuomarara kwepasi kwakakura kupfuura kuomarara kwepakati 30 HV kuomarara ukoshi hunoratidza kuti mufananidzo wakaiswa carburized.Kune zvigadzirwa zvine mamakisi 8.8 kusvika 12.9, mutsauko uripo pakati pekuoma kwepamusoro uye kuomarara kwepakati unogona kushandiswa kuona kana chigadzirwa chine carburizing pamusoro.Kuoma kwechigadzirwa hakuna zvakananga kune theoretical tensile simba.Kutsunga kwehuwandu hwekuoma kwehuwandu hakubvi pakufunga kwemuganhu wepamusoro wesimba.
Ongorora: Izvo zvinofanirwa kucherechedzwa kuti kusiyanisa kwekuoma kukosha kwekuwedzera kunokonzerwa nekupisa kurapwa carburizing kana kutonhora kushanda.
