Ahunga: rahi paerewa. rahi Paerewa o ahunga

Ko te huihui whanau motuhake i te mea he wāhanga o te take tautoko mō te tautoko me te hoki tītaka okeoke i te muri, kahore te waku mate o te pūngao ranei. He maha ngā momo o taua wāhanga. I roto i tenei take, te rahi o te ahunga i roto i nuinga o te wā whakaritea e GOST.

momo

Kōpuku o tenei momo e whakamahia i roto i te ahumahi, me te he rawa whānuitia atu rāngai o te ōhanga. He hydrostatic, hau-pateko, ahunga autō, me ētahi atu rōpū. Heoi, i te momo tino noa ko nga knots pepa me te awhiowhio. E ai ki te kawenga mohio a e wehea e rua o enei rōpū ki:

• Pūtoro;

• ātete;

• whakapā koki.

ahunga awhiowhio

Ko te āhuatanga matua o tenei momo kōpuku he pōro e kei awa i tetahi tawhiti i ia atu i roto i te taata tei mau motuhake ranei, ka karanga te whakawehe. I roto i te tukanga, hurihia ratou te whanau i runga i te faananea i mo e rua mowhiti, tetahi o nei i roto i te nuinga o te wā he pateko. Kōpuku o tenei momo e whakamahia i roto i te ahumahi te tino. Ko te meka ko e i roto i te rite ki te ahunga ringaringa, to ratou he maha o ngā painga. Ki te hunga ngā waku matua iti, me te iti kohi hinu. Whakangāwari o te whakamahi, me te tāuta - Ko te ano hoki tenei te mea te rerekētanga i waenganui i taua ahunga. Standards (regulates GOST ratou rahi) o taua wae aroaro i roto i te papa motuhake. Na reira, ki te kitea he tika i roto i te take ngā, e mau ana e kore kia nui kaha. Kōpuku o tenei momo e taea te whiriwhiri tino tetahi hoahoa momo.

Tūtohutanga ki te wiri me te ru - anake te drawback, e rerekē i roto i taua ahunga. Me tika kia aru Standards i roto i to ratou production. Kore e kore ratou e muri hoki roa rawa.

Ngā momo o ahunga awhiowhio

I tua atu ki te ahotea o tenei momo o kōpuku e whakarōpūtia ki ngā rōpū rite ki te paearu e whai ake nei:

• Āhua āhuatanga awhiowhio. I roto i te faatura i tenei, te wehe pōro me te takai ahunga. Okeoke huānga ia kia koeko te momo muri, porotakaroa, ngira-āhua, miro, oko-āhua, ka pera i runga i. D.

• E ai ki te samoustanovleniya kaha. I roto i tenei take, te wehewehe i waenganui i ahunga porohita me te nesamoustanavlivayuschiesya.

• E ai ki te maha o ngā huānga awhiowhio. He ahunga rarangi kotahi, me te rua.

• I roto i te rahi. Katoa hua ki te rā te whanau i runga i tenei kaupapa e wehea ki te maha raupapa.

Tei runga i te raupapa i te diameter roto taua, kia rerekē te whanui o te whanau me tona D waho. He ahunga whakamahia i roto i te whakaminenga o waka, pereo, Windmills me pera i runga i. D.

āhuatanga

Ngā āhuatanga o tenei momo kōpuku tautuhi te GOST 3478-79. A, no te te makona reira e whiwhi ahunga rawa kaha, me te roa. E pā ana ēnei paerewa ki ngā momo katoa o nga whakaminenga takai, ki te kahore hoki tauira whakaaro motuhake, me te hoahoa motuhake. I roto i te take whakamutunga, e taea te hanga te wāhanga hei momo o te rahi, te tika tino mo te hoahoa ngā.

Tirohia te ahunga rahi paerewa e taea, rite kua whakahuatia ia raupapa, i roto i nga tepu motuhake e tohu nga diameters waho, me te roto, te rohe iti rawa rahi (Rmin), me te whanui iti o nga mowhiti roto, me te waho (B). Ka rite ki te tauira, hoatu e matou te tepu koe mo te raupapa e mau ana diameters 8 (haapotohia).

More taea te kitea tepu taipitopito i roto i te tuhinga motuhake. He hoki paerewa i roto i ahunga Kāpehu - he ētita whakairoiro, hangaia hoki hoahoa rorohiko-whakakaha (hoahoa i roto i te whare pukapuka). He tepu mo te diameters rerekē o kōpuku.

akomanga tika

rahi Paerewa o okeoke ahunga, kia e taea e koe te ako i te tepu motuhake. Heoi, i roto i ētahi wā, tukua etahi ine i roto i te āhuatanga o te GOST. E wehea ahunga piha haapiiraa tika ki:

• noa "0";

• "6" o te tika tiketike;

• teitei "5";

• osobovysokoy "4";

• ultra-teitei "2".

Kōpuku mō ngā hanganga rerekē, ka taea e whai ngā tukunga pai-tautuhi. Ko te kupu, hei tauira, paerewa mo te whanau pasikala (608 momo) he:

• pōro kātakí - 0 / -0.005;

• ara i roto - + 0.0001 / -0.0003;

• iwi waho - + 0.0001 / -0.0005.

iku'anga

ahunga awhiowhio paerewa i roto i to ratou hanga haapa'o ki whakahauanga. I roto i te tikanga e taea te kite kiritaki he aha te ahua o te kono i roto i mua o ia ia, a hoki aha e taea ki te whakamahi i motuhake tohu tono. ahunga whakaritea te nuinga o whaowhao whakaturia o tau. I te tahi taime ngā tapanga paerewa pukapuka e rua. I roto i tenei take:

• Ko te tau tuatahi reta ranei tohu te momo o te whanau.

• Ko te tau e rua i muri whakatau te ope o te raupapa. Ko te rōpū tuatahi tohu te whanui ranei teitei, te tuarua - te diameter.

• Ko te mati e rua whakamutunga tohu te diameter o te waehere whakatuwheratanga. Ki te tini tatou i te reira i te 5, ka taea e tatou te whiwhi i te rahi d i roto i te mm.

rahi Paerewa o ahunga 66 414 (i roto i tenei take tīpakohia te whakatō i roto i runga i te GOST 3325-85), hei tauira, e whai ake:

• d - 70 mm;

• D - 180 mm;

• whanui - 42 mm;

• taimaha - 5,74 kg.

ahunga Tōkau

Units o tenei momo ngā o e rua ngā āhuatanga taketake: te Ōseni takere me i waenganui i he lubricants motuhake. Ko te painga matua o enei ahunga e matua āwangawanga diameters iti, me te te kaha ki te hanga a ratou, ka whakamahi i take wetekina he hoahoa rawa uaua. E whakaaro ana te āhuatanga o te kōpuku o tenei momo ki te kia e kore rawa te roa o te ora ratonga me te hiahia mō te lubricants utu nui.

Ngā momo o ahunga kiriata

I te kau, i reira he kōpuku o tenei rōpū:

• nui-tere;

• Mono (whakamahia, hei tauira, i roto i crankshafts);

• mīhini pū, tika ārahi ngahaú, me te faatupu whakatikatika o te āputa;

• huarahi iti-tere cheap;

• tikanga ki te mahi i raro i ngā āhuatanga motuhake (te wai, taiao ha'iriiri).

Tei runga i te aratau whakahaere o te whanau o tenei momo pea i roto i te waku inu semifluid ranei. I roto i te take tuatahi e wehea te mata mahi o te whare, me te take i paparanga kaua matotoru o te hinu. A, no te te tapiritia waku whakauru ki te rohe wai (te hinu i roto i te kiriata rawa kikokore i hanga e rāpoi here).

Ahu retireti ahunga

Āhuatanga o ngā pae i roto i tenei rōpū e whakaritea e GOST 2795. Raraunga i tepu motuhake - he hoki reira te mea e hiahiatia ana te ki te tango ki te pūkete mā te hanga i taua ahunga. Ko te paerewa i roto i tenei take pā ki tawhā pēnei i:

• diameter waho, me te roto;

• te roa (l);

• Ahu chamfering (C);

• ngā tukunga (ngā tukunga).

Ko te ripanga i raro nei (CONDENSED) fakafofonga'i e nga rahi paerewa o retireti ahunga o rerekē rarangi.

Āhuatanga me Materials

Paerewa o ahunga mania, reira, kei te tino tautuhi GOST. Whakaritea etahi whakaritenga ki te kounga o ngā rauemi whakamahia mo ratou hanga. Amo whare kiriata, rite kua whakahuatia, e taea e te reira katoa wahia ranei. I roto i te take whakamutunga, kei te maha whakamahia te hononga titi motuhake ranei raka. Ko te whakauru ko te whanau retireti i hanga rite te ringaringa. I roto i te kōwae wahi kotahi taea te hanga i te reira o rua haurua. I nga ngahaú, warping, te tikanga eke ahunga whaiaro-whakahāngai i.

Ka taea te whakamahi i te rauemi e whai ake nei mō te hokohoko i tenei momo o kōpuku:

• rino (whare);

• parahi, maka rino kirihou (mō kōhao) ranei.

I roto i ētahi wā, engari tino rawa onge, kua hanga bushings o te rakau, ara papa maramara ranei.

whakaritenga taketake

Ko te kupu, ko te paerewa ahunga (ranei kaua, ratou whakatinanatanga) tukua ki te whakaputa kounga mōrahi, roa-tonu, me te mahi pai. Me whakatau i te kōpuku o te rōpū te whakaritenga e whai ake nei:

• kia nga rauemi me te hoahoa o te ahunga retireti pērā i ki te whakarato iti waku i waenganui i te whare me te ringaringa.

• kia kaha, me te wae rigidity pērā e taea te tu i te reira i tetahi utanga hiahiatia.

• Pōwhiritia hoahoa tapatahi whanau mōrahi. I roto i te tāutanga reira kia kore fifi.

• Hei whakaputa i te ahunga kia whai ratou rawaka mata ki te tatau tupu i roto i te mahi o te rohe wera.

Kia pehea te mahi

Hanga ahunga mania, me te okeoke i runga i hinonga nui motuhake, te nuinga o ngā rua awheawhe matua: waiariki, me te hangarau e. maha whakahaere rārangi Runanga taua tipu i roto i te aratau aunoa. Haunga a ratou, kua tāuta hoki te toa mihini hou riringi.

I roto i to tatou whenua he wae i hanga e te kaiwhakanao kāinga, me te rite i roto i Switzerland (SKF) te tino rongonui. Ko te taua rite i roto i Russian SKF ahunga paerewa.
