Choyamba, dongosolo loyambira la kubereka
Zofunikira pakubala: mphete yamkati, mphete yakunja, thupi lozungulira, khola
Mphete yamkati: nthawi zambiri imagwirizana kwambiri ndi shaft, ndikuzungulira pamodzi.
Mphete yakunja: nthawi zambiri imakhala ndi kusintha kwa mpando, makamaka kuthandizira zotsatira zake.
Mphete yamkati ndi yakunja imakhala ndi zitsulo GCr15, ndipo kuuma pambuyo pa chithandizo cha kutentha ndi HRC60 ~ 64.
Kugubuduza chinthu: mwa khola wogawana anakonza mu mphete mkati ndi kunja mphete ngalande, mawonekedwe ake, kukula, chiwerengero mwachindunji bwanji kubala katundu kubala mphamvu ndi ntchito.
Cage: Kuphatikiza pakulekanitsa chinthu chogubuduza, imawongoleranso kuzungulira kwa chinthu chogudubuza ndikuwongolera bwino momwe mafuta amagwirira ntchito mkati mwake.
Mpira wachitsulo: Zinthuzo nthawi zambiri zimakhala ndi zitsulo GCr15, ndipo kuuma pambuyo pa chithandizo cha kutentha ndi HRC61 ~ 66.Mlingo wolondola umagawidwa mu G (3, 5, 10, 16, 20, 24, 28, 40, 60, 100, 200) kuchokera pamwamba mpaka pansi malinga ndi kulolerana kwapakati, kulolerana kwa mawonekedwe, mtengo wa gauge ndi roughness pamwamba.
Palinso dongosolo lothandizira lothandizira
Kuphimba fumbi (kutsekera mphete): Kulepheretsa zinthu zachilendo kulowa m'chifaniziro.
Mafuta: mafuta, kuchepetsa kugwedezeka ndi phokoso, kuyamwa kutentha kwamphamvu, kuwonjezera nthawi yogwira ntchito.
Chachiwiri, gulu la zimbalangondo
Malinga ndi mikangano ya zigawo zosuntha ndizosiyana, mayendedwe amatha kugawidwa m'magawo ogubuduza ndikugudubuza magawo awiri.M'mabere ogudubuza, odziwika kwambiri ndi ma bere a mpira wakuya, ma cylindrical roller bearings ndi ma thrust mpira.
Mipira yozama kwambiri imanyamula katundu wambiri, komanso imatha kunyamula katundu wa radial ndi axial katundu palimodzi.Pamene katundu wa radial yekha agwiritsidwa ntchito, Angle yolumikizana ndi ziro.Mpira wakuya wa groove ukakhala ndi chilolezo chokulirapo kwambiri, umakhala ndi mawonekedwe olumikizana ndi ma axial ndipo umatha kupirira katundu wokulirapo wa axial, kugundana kwa mpira wakuzama wa groove kumakhala kochepa, komanso liwiro lozungulira ndilokwera kwambiri.
Mipira yozama yakuya ndiyo ma fani akugudubuzika kwambiri okhala ndi ntchito zosiyanasiyana.Ndi yoyenera kusinthasintha kothamanga kwambiri komanso ngakhale kuyendetsa mofulumira kwambiri, ndipo imakhala yolimba kwambiri ndipo sifunikira kukonzanso kawirikawiri.Mtundu woterewu umakhala ndi mikangano yaying'ono, kuthamanga kwa malire, mawonekedwe osavuta, mtengo wotsika wopanga komanso wosavuta kukwaniritsa zolondola kwambiri zopanga.Kukula kwake ndi kusintha kwa zinthu, komwe kumagwiritsidwa ntchito pazida zolondola, ma motors otsika phokoso, magalimoto, njinga zamoto ndipo nthawi zambiri makina ndi mafakitale ena, ndiye mtundu wodziwika kwambiri wamakina opanga makina.Makamaka chimbalangondo katundu radial, angathenso kunyamula kuchuluka kwa axial katundu.
Chovala chodzigudubuza cha cylindrical, thupi lodzigudubuza ndi gawo lapakati la cylindrical roller bear.Ma cylindrical roller bears ndi raceway ndi mizere yolumikizana.Kulemera kwakukulu, makamaka kunyamula katundu wa radial.Kukangana pakati pa chinthu chogubuduza ndi m'mphepete mwa mphete ndi kakang'ono, komwe kuli koyenera kugwira ntchito mofulumira kwambiri.Malingana ndi ngati mpheteyo ili ndi flange, ikhoza kugawidwa mu NU \ NJ \ NUP \ N \ N \ NF ndi mizere ina ya mzere umodzi, ndi NNU \ NN ndi zina zonyamula mizere iwiri.
Chophimba cha cylindrical chokhala ndi mphete yamkati kapena yakunja yopanda nthiti, yomwe mphete zake zamkati ndi zakunja zimatha kusunthana wina ndi mnzake axially ndipo motero zingagwiritsidwe ntchito ngati chotengera chaulere.Mbali imodzi ya mphete yamkati ndi mphete yakunja imakhala ndi nthiti iwiri, ndipo mbali ina ya mpheteyo imakhala ndi cylindrical roller yokhala ndi nthiti imodzi, yomwe imatha kupirira katundu wa axial motsatira njira imodzi.Nthawi zambiri makola achitsulo amagwiritsidwa ntchito, kapena makola olimba opangidwa ndi aloyi yamkuwa.Koma ena a iwo amagwiritsa ntchito polyamide kupanga makola.
Mipira ya thrust idapangidwa kuti izitha kupirira zolemetsa panthawi yothamanga kwambiri ndipo imapangidwa ndi mphete za gasket zokhala ndi njira yothamangira mpira.Chifukwa mpheteyo ndi mawonekedwe a mpando, mpira wokhomerera umagawidwa m'mitundu iwiri: mtundu wa flat base pad ndi kugwirizanitsa mpando wozungulira.Kuphatikiza apo, mayendedwe otere amatha kupirira katundu wa axial, koma osati katundu wa radial.
Mpira wokhomerera umakhala ndi mphete yapampando, mphete ya shaft ndi msonkhano wachitsulo wachitsulo.Mphete ya shaft imagwirizana ndi shaft, ndipo mphete yapampando imagwirizana ndi chipolopolo.Mapiritsi a mpira amangoyenera kunyamula gawo la katundu wa axial, mbali zotsika kwambiri, monga mbedza za crane, mapampu osunthika, ma centrifuges, ma jacks, ma retarders otsika, etc. Mphete ya shaft, mphete ya mpando ndi thupi lozungulira olekanitsidwa ndipo akhoza kuikidwa ndi disassembled padera.
Chachitatu, kugubuduza kubala moyo
(1) Main kuwonongeka mitundu ya anagubuduza mayendedwe
Kutopa kwakanthawi:
Mu mayendedwe ogubuduza, kunyamula katundu ndi kusuntha kwapamtunda wa kukhudzana (njira yothamanga kapena yozungulira thupi), chifukwa cha katundu wopitirira, woyamba pansi pamadzi, kuya kofanana, gawo lofooka la mng'alu, ndiyeno limakula mpaka kukhudzana pamwamba, kuti pamwamba wosanjikiza zitsulo flake kunja, chifukwa mu kubereka sangathe ntchito bwinobwino, chodabwitsa amatchedwa kutopa spalling.The chomaliza kutopa spalling wa anagubuduza fani ndi zovuta kupewa, Ndipotu, pankhani ya unsembe yachibadwa, kondomu ndi kusindikiza, ambiri a kubala kuwonongeka ndi kutopa kuwonongeka.Chifukwa chake, moyo wautumiki wa mayendedwe nthawi zambiri umatchedwa moyo wautumiki wa kutopa wa mayendedwe.
Pulasitiki deformation (mapindikidwe okhazikika):
Pamene kugubuduzika kukakhala ndi katundu wambiri, kupindika kwa pulasitiki kumachitika m'thupi logudubuza ndikugubuduza kukhudzana, ndipo kugubuduza pamwamba kumatulutsa chiboliboli, zomwe zimapangitsa kugwedezeka kwakukulu ndi phokoso panthawi yoyendetsa.Kuphatikiza apo, tinthu tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono tambiri, kapena mayendedwe atayima, chifukwa cha kugwedezeka kwa makina ndi zinthu zina zimatha kutulutsa kumtunda komwe kumalumikizana.
Valani ndi kung'amba:
Chifukwa cha kusuntha kwapang'onopang'ono kwa chinthu chogubuduza ndi msewu wothamanga komanso kuwukiridwa kwa dothi ndi fumbi, kugudubuza ndi kugubuduza pamwamba kumayambitsa kutha.Pamene kuchuluka kwa kuvala kuli kwakukulu, chilolezo chonyamulira, phokoso ndi kugwedezeka kumawonjezeka, ndipo kuthamanga kwapamwamba kumachepetsedwa, kotero kumakhudza mwachindunji kulondola kwa injini zina zazikulu.
Chachinayi, kuchuluka kwa kulondola komanso njira yowonetsera phokoso
Kulondola kwa ma bearings ogubuduza kumagawidwa kukhala kulondola kwa dimensional ndi kulondola kozungulira.Mulingo wolondola wakhazikika ndipo wagawidwa m'magulu asanu: P0, P6, P5, P4 ndi P2.Kulondola kwasinthidwa kuchokera pamlingo wa 0, poyerekeza ndi kugwiritsa ntchito mwachizolowezi kwa mlingo 0 ndikokwanira, malingana ndi mikhalidwe kapena zochitika zosiyanasiyana, mulingo wofunikira wolondola siwofanana.
Asanu, omwe amafunsidwa kawirikawiri
(1) Kukhala ndi zitsulo
Mitundu yomwe imagwiritsidwa ntchito nthawi zambiri yachitsulo chogubuduza: zitsulo zapamwamba za carbon zovuta, zitsulo zokhala ndi carburized, zitsulo zosapanga dzimbiri, zitsulo zotentha kwambiri.
(2) Kupaka zitsulo pambuyo pa kukhazikitsa
Kupaka mafuta kumagawidwa m'magulu atatu: mafuta, mafuta opangira mafuta, mafuta olimba
Kupaka mafuta kumatha kupangitsa kuti chotengeracho chiziyenda bwino, kupewa kulumikizana pakati pa msewu wothamanga ndi malo ogudubuza, kuchepetsa kukangana ndi kuvala mkati mwa mayendedwe, ndikuwongolera nthawi yogwirira ntchito.Mafuta amamatira bwino komanso amavala kukana komanso kukana kutentha, zomwe zimatha kupititsa patsogolo kukana kwa okosijeni kwa mayendedwe a kutentha kwambiri ndikuwonjezera moyo wautumiki wa mayendedwe.Mafuta omwe ali muzitsulo sayenera kukhala ochuluka, ndipo mafuta ochulukirapo adzakhala otsutsana.Kukwera kwa liwiro la kunyamula, kumayambitsa kuvulaza.Adzapanga kubereka kugwira ntchito pamene kutentha kuli kwakukulu, kudzakhala kosavuta kuonongeka chifukwa cha kutentha kwakukulu.Choncho, ndikofunikira kwambiri kudzaza mafuta mwasayansi.
Chachisanu ndi chimodzi, kukhala ndi kusamala unsembe
Musanakhazikitse, tcherani khutu kuti muwone ngati pali vuto ndi khalidwe la kubereka, sankhani molondola chida choyikapo chofananira, ndipo samalani ndi ukhondo wa bere pamene mukuyikira.Samalani ngakhale mwamphamvu pamene mukugogoda, ndikugogoda mofatsa.Yang'anani ngati mayendedwe aikidwa bwino mutatha unsembe.Kumbukirani, ntchito yokonzekera isanathe, musatulutse katunduyo kuti mupewe kuipitsidwa.
