Pokonza makina, kugwiritsa ntchito zitsulo ndizofala kwambiri, koma nthawi zonse pamakhala anthu ena omwe sangamvetse mavuto ena pogwiritsira ntchito zitsulo, monga kusamvetsetsana katatu komwe kunayambika pansipa.
Bodza 1: Kodi ma bearings si muyezo?
Munthu amene amafunsa funso ili ali ndi chidziwitso cha mayendedwe, koma sikophweka kuyankha funsoli.Ziyenera kunenedwa kuti ma bearings onse ndi magawo okhazikika osati magawo okhazikika.
Kapangidwe, kukula, kujambula, kuyika chizindikiro ndi mbali zina za magawo okhazikika ndizokhazikika.Zimatanthawuza kunyamula kwa mtundu womwewo, mawonekedwe a kukula kofanana, ndi kusinthasintha kwa kukhazikitsa.
Mwachitsanzo, ma bere 608, miyeso yawo yakunja ndi 8mmx m'mimba mwake 22mmx m'lifupi 7mm, ndiko kunena kuti, ma bere 608 ogulidwa ku SKF ndi ma 608 ogulidwa ku NSK ndi ofanana ndi mawonekedwe akunja, ndiko kuti, mawonekedwe aatali.
M’lingaliro limeneli, tikamanena kuti kunyamula ndi gawo lokhazikika, kumangotanthauza maonekedwe ndi mutu womwewo.
Tanthauzo lachiwiri: zimbalangondo sizigawo zokhazikika.Wosanjikiza woyamba amatanthauza kuti, kwa 608 mayendedwe, kukula kwakunja kuli kofanana, zamkati sizingakhale zofanana!Zomwe zimatsimikizira kugwiritsidwa ntchito kwa nthawi yayitali ndi magawo amkati.
Zomwezo za 608, mkati mwake zimatha kusiyana kwambiri.Mwachitsanzo, chilolezo chikhoza kukhala MC1, MC2, MC3, MC4, ndi MC5, kutengera kulekerera koyenera;Makola amatha kupangidwa ndi chitsulo kapena pulasitiki;Kulondola kungakhale P0, P6, P5, P4 ndi zina zotero malinga ndi cholinga chosankhidwa;Mafuta amatha kusankhidwa kuchokera pamwamba mpaka kutentha pang'ono m'njira mazana ambiri malinga ndi momwe amagwirira ntchito, komanso kuchuluka kwa kusindikiza mafuta kumasiyananso.
M'lingaliro ili, timati kubereka si gawo lokhazikika.Kutengera momwe amagwirira ntchito, mutha kupereka magwiridwe antchito osiyanasiyana a 608 ma bearings pazosankha zanu.Kuti ikhale yokhazikika, ndikofunikira kufotokozera magawo omwe amanyamula (kukula, mawonekedwe osindikizira, zinthu za khola, chilolezo, mafuta, kuchuluka kwa kusindikiza, etc.).
Kutsiliza: Kwa ma bearings, simuyenera kungowawona ngati magawo okhazikika, tiyenera kumvetsetsa tanthauzo la magawo omwe siwoyenera, kuti tisankhe ma bere oyenera.
Bodza lachiwiri: Kodi zonyamula zanu zitha zaka 10?
Mwachitsanzo, mukagula galimoto, sitolo ya 4S imagulitsa ndipo wopanga amadzitamandira ndi chitsimikizo kwa zaka zitatu kapena makilomita 100,000.Mutagwiritsa ntchito kwa theka la chaka, mumapeza kuti tayala lathyoka ndikuyang'ana sitolo ya 4S kuti mulipire.Komabe, mukuuzidwa kuti sichikuphimbidwa ndi chitsimikizo.Zalembedwa bwino mu buku chitsimikizo kuti chitsimikizo cha zaka 3 kapena makilomita 100,000 ndi zongochitika, ndi chitsimikizo ndi mbali pachimake galimoto (injini, gearbox, etc.).Tayala lanu ndi gawo lovala ndipo silili pachiwonetsero.
Ndikufuna ndifotokoze momveka bwino kuti zaka zitatu kapena ma kilomita 100,000 omwe mudapempha ndi ofunikira.Chifukwa chake, nthawi zambiri mumafunsa kuti "kodi mabatani amatha zaka 10?"Palinso mikhalidwe.
Vuto lomwe mukufunsa ndi moyo wautumiki wa ma bearings.Kwa moyo wautumiki wa mayendedwe, uyenera kukhala moyo wautumiki pansi pazikhalidwe zina zautumiki.Sizingatheke kulankhula za moyo wautumiki wa mayendedwe popanda kugwiritsa ntchito zikhalidwe.Momwemonso, zaka zanu za 10 ziyeneranso kutembenuzidwa kukhala maola (h) malinga ndi nthawi yeniyeni yogwiritsira ntchito mankhwala, chifukwa kuwerengera moyo wobereka sikungathe kuwerengera chaka, chiwerengero cha maola (H).
Ndiye, ndi zinthu ziti zomwe zimafunika kuti muwerenge moyo wautumiki wa ma beya?Kuwerengera moyo wautumiki wa mayendedwe, nthawi zambiri ndikofunikira kudziwa mphamvu yonyamula (axial force Fa ndi radial force Fr), liwiro (kuthamanga kothamanga, yunifolomu kapena kuthamanga kosinthika), kutentha (kutentha pantchito).Ngati ndi yotseguka, muyenera kudziwa kuti mafuta opaka mafuta oti mugwiritse ntchito, ukhondo ndi zina zotero.
Ndizimenezi, tiyenera kuwerengera miyoyo iwiri.
Moyo 1: moyo woyengedwa wokhazikika wokhala ndi L10 (onani kutalika kwa kutopa kwakuthupi komwe kumachitika)
Ziyenera kumveka kuti moyo wodziwika bwino wa mayendedwe ndikuwunika kupirira kwa mayendedwe, ndipo moyo wowerengera wa 90% wodalirika nthawi zambiri umaperekedwa.Fomula yokhayo ikhoza kukhala yosakwanira, mwachitsanzo, SKF kapena NSK ikhoza kukupatsani ma coefficients osiyanasiyana owongolera.
Moyo wachiwiri: moyo wapakati wamafuta L50 (mafuta adzauma nthawi yayitali bwanji), mawerengedwe amtundu wa wopanga aliyense sali wofanana.
Kukhala ndi moyo wamafuta ambiri L50 kumatsimikizira moyo womaliza wantchito, ngakhale zili bwino bwanji, palibe mafuta opaka mafuta (mafuta amauma), kukangana kouma kumatha mpaka liti?Chifukwa chake, moyo wapakati wamafuta L50 umawonedwa ngati moyo womaliza wautumiki (zindikirani: moyo wamafuta ambiri L50 ndi moyo wowerengedwa ndi mawonekedwe amphamvu ndi kudalirika kwa 50%, komwe kumangogwiritsidwa ntchito ndipo kumakhala ndi kuzindikira pakuwunika kwenikweni).
Kutsiliza: Kutalika kwa kunyamula kungagwiritsidwe ntchito kumadalira momwe zimakhalira.
Bodza lachitatu: Mapiritsi anu ndi ophwanyika kwambiri moti amagwera pansi popanikizika
Kuthamanga pang'onopang'ono kumakhala kosavuta kukhala ndi phokoso losazolowereka, kusonyeza kuti mabala amkati omwe ali ndi zipsera, ndiye, kodi zipsera zamkati zonyamula zimapangidwa bwanji?
Pamene kubereka kumayikidwa kawirikawiri, ngati mphete yamkati ndi malo okwera, ndiye kuti mphete yamkati idzapanikizidwa, ndipo mphete yakunja sidzagwedezeka, ndipo sipadzakhala zipsera.
Koma bwanji ngati, m’malo mochita zimenezo, mphete zamkati ndi zakunja zinali zokongoletsedwa mogwirizana?Izi zimapangitsa kuti Brinell indentation, monga momwe zilili pansipa.
Inde, mukuwerenga bwino, ndi nkhanza zenizeni ngati kunyamula mkati ndi kunja mphete wachibale nkhawa, basi kuthamanga pang'onopang'ono, kunyamula n'zosavuta kutulutsa kuwonongeka indentation pamwamba pa mpira zitsulo ndi pamwamba mpikisano, ndiyeno kutulutsa mawu achilendo. .Chifukwa chake, malo aliwonse oyika omwe angapangitse mphamvu yakunyamula mkati ndi kunja kwa mpheteyo imatha kuwononga mkati mwa chonyamuliracho.
Kutsiliza: Pakalipano, pafupifupi 60% ya kumveka kwachilendo kumachitika chifukwa cha kuwonongeka komwe kumachitika chifukwa cha kuyika kosayenera.Choncho, m'malo moyesa kupeza vuto la opanga obereka, ndi bwino kugwiritsa ntchito mphamvu zaukadaulo za opanga zonyamula kuyesa kaimidwe kawo, ngati pali zoopsa ndi zoopsa zobisika.
