Zvipingamupinyi zveMashandisirwo uye Magadzirirwo eMunda

Kupfuura gungano, kugadzirisa ndiko uko kukanganisa kwemuchinjikwa kunoburitswa pachena. Ngura, pendi, tsvina—zvose zvinozadza zororo iroro chairo. Ndapedza maawa asingaverengeki pamasevhisi ekufona uko dambudziko chairo rakanga risiri iro rakakundikana, asi musoro wekusungirira wakaita ngura kana kuvharika zvekuti hapana mutyairi aigona kuruma. Kune zvakakosha zvivakwa, ichi chikanganiso chekugadzira. Muchinjikwa wemuchinjiko, kunyanya Phillips, hauna kunaka kune yakakwirira-corrosion kana yakakwirira-vibration nharaunda umo disassembly inotarisirwa. Musanganiswa dhiraivha (muchinjiko une sikweya) kana Torx inowanzova sarudzo irinani yehupenyu hwose, kunyangwe pamutengo wepamusoro.

Pane manomano, hongu. Kuchenesa kunze nekunhonga, uchishandisa mutyairi wekukanganisa ane nyowani, yemhando yepamusoro bhiti, uye kuzora mafuta anopinda mukati memusoro wemusoro (kwete chete shinda) anogona kuita zvishamiso. Asi izvi zvigadziriso zvemumunda. Iyo irinani mhinduro ndeyekumberi kwekutsanangurwa: kusarudza iyo chaiyo dhiraivha mhando, inodzivirira corrosion coating seGeomet kana Dacromet, uye nekuona kuti vashandi vegungano vane vatyairi vakaringana, vakachengetedzwa zvakanaka. Zvinonzwika zvakakosha, asi zvinokatyamadza kuti kangani kutevedzana uku kunoputsika.

Ini ndinorangarira kuisirwa purazi rezuva uko mabhuraketi enjanji anokwira akashandisa PZ3 masikuru asina tsvina. Kondirakiti akashandisa magetsi ane standard PH3 bits. Panguva iyo mutsara wekutanga wakakwira, pamwe 30% yescrew misoro yaive yakakuvadzwa. Isu taifanira kumisa basa, gadzira iyo chaiyo PZ3 maitiro mabheti, uye kutsiva yega yega yakakanganisika fastener. Iko kunonoka kunodhura kupfuura iyo yese fastener odha. Chidzidzo chaive chekuti fastener specition sheet haina basa kana isingasviki pamaoko achinyatso shandura maturusi.

Ramangwana reMuchinjikwa Drive

Muchinjikwa wemuchinjikwa wava kusashanda here? Kana bodo. Kune huwandu hwakakura hwemashandisirwo, kunyanya muhuni, simbi yakareruka, uye mapurasitiki, mutengo-unoshanda uye nyore hazvikundike. Iyo Phillips system's cam-out ficha, inowanzo shorwa nevainjiniya, ibhenefiti mukuungana otomatiki kwemagetsi evatengi kana fenicha uko ukobvu hwezvinhu hunosiyana. Inodzivirira kupwanya. Chinokosha kushandisa nemaune.

Madhiraivha matsva akaita sePhillips/Square combo ari kuwana pasi, achipa kumhanya kwemuchinjiko wemuchinjiko pamwe netorque yakanaka yesquare drive. Asi vanoda zvidimbu zvakakosha. Mune akawanda akakwira-vhoriyamu, anoona mutengo wekugadzira zvikamu, iyo yechinyakare muchinjika fastener, inogadzirwa zvinobudirira muhombe hubs seYongnian, icharamba iri mambo. Iko kushanduka kuri pamusoro pesainzi yezvinhu-yakasimba, yakareruka alloys-uye mapuratifomu epamberi ekuwedzera hupenyu hwesevhisi, pane kusiiwa kwakazara kwefomu recess.

Kune kambani inogadzira yakanyudzwa mune iyo ecosystem, dambudziko nderekuenzanisa kugadzirwa kwevhoriyamu nekukura kuri kudiwa kwehunyanzvi. Haisi yekungoita bhiriyoni yePhillips screws. Zviri zvekuva nekwaniso yekumhanyisa batch yePZ2 screws muA4-80 isina tsvina ine chaiyo dema oxide coating yemutengesi wemotokari yeEuropean, uyezve kuchinja kune kumhanya kwePH1 brass screws yemagetsi zvigadziriso. Kuchinjika mukati mehunyanzvi hwezvigadziriso ndiyo chaiyo yemakwikwi edge ikozvino.

Kupedzisa Pasina Uta

Saka, muchinjiko wemuchinjiko. Icho chidimbu chidiki cheinjiniya geometry inobata nyika yemazuvano pamwechete, asi kazhinji kacho inofungidzirwa shure. Kuita kwayo kunotsamira pakubatana kusinganzwisisike pakati pedhizaini recess, mutyairi bit mhando, ruzivo rwevashandisi, uye nharaunda yekushandisa. Kubata ese madhiraivha akafanana inzira yekukurumidza yekuunganidza misoro uye kutadza kwemunda.

Kubudirira kushandiswa kunouya pakuremekedza kwayo chaiyo. Taura Pozidriv paunenge uchida torque pasina cam-out. Rondedzera Phillips kana iwe uchida iyo inodzorwa slip. Ita shuwa kuti cheni yekugovera, kubva kumugadziri kuenda kuhomwe yekushandisa, inoremekedza iyo musiyano. Uye kana uchitsvaga, funga nezve zvivakwa zviri kuseri kwemutengesi-kambani iri pakati pedunhu reChina rinokurumidza, senge yambotaurwa, kazhinji ine mukana unobatika mukuenderana uye kubata kwehunyanzvi chaizvo nekuti yakakomberedzwa neiyo indasitiri yese ecosystem.

Pakupedzisira, chinhu chinoda kutariswa zvakanyanya kupfuura zvachinowanzo kuwana. Kuzvigadzirisa hazvionekwe. Kuzviita zvisizvo kunomisa mitsetse yekugadzira, kuvhiringa nyanzvi, uye kukanganisa zvigadzirwa. Ndihwo huremu chaihwo hunofanira kutakura muchinjikwa wakapfava.
