Ngā Whakatakotoranga Wira Mekameka o te Wina Punga DIN 766 764 ISO | Yining Hydraulic
TL;DR — Ngā Whakaaro Matua
- Kāore ngā wira mekameka DIN 766 (hononga-poto) me te DIN 764 (hononga-roa) e hototahi ana — he rerekē te papa pōke tata ki te 33%, ā, mā te tāutanga hē o te mekameka ka tere ake te pakaru o te porotiti, te here mekameka, me te peke pea o te mekameka i raro i te kawenga.
- Ko te pakeke o te rauemi wira mekameka o te HRC 45-50 me ngā taha niho whakapakeke-whakapūmau te whakatakotoranga iti rawa mō ngā tono wini punga moana.— ko ngā rauemi ngohengohe (kei raro i te HRC 40) e whakaatu ana i te pakaru o te pute i muri i te 500-800 huringa i roto i ngā taiao rehu tote.
- He hototahi ngā wīra mekameka ISO 16726 ki te DIN 766 mō ngā diameter mekameka noa (13mm-26mm), engari e tohu ana te paerewa ISO i te manawanui pute kikī ake (+0.3mm vs DIN's +0.5mm)— arā, ka mahi tahi te wira kua whakatauria e te ISO me te mekameka DIN, engari kāore pea te wira DIN e tutuki i ngā whakaritenga mō te manawanui ISO.
He aha te "Wīra Mekameka Paerewa" ehara i te Whakatakotoranga Ao Whānui — Ngā Paerewa e Toru e Whakataetae Ana
Tekau mā rima tau ahau e hoahoa ana i ngā pūnaha wini waipēhi i Yining Hydraulic, ā, ko te hapa whakatakotoranga tino utu nui ka tūtaki ahau i roto i te hoko wini punga ko te whakaaro he rite tonu te tikanga o te "wira mekameka paerewa" puta noa i ngā kaihanga katoa.E toru ngā paerewa mekameka matua e whakamahia whānuitia ana puta noa i te ao — DIN 766, DIN 764, me te ISO 16726/ISO 67 — ā, e kore e taea te whakamahi haumaru i tētahi wira mekameka i hangaia mō tētahi paerewa me tētahi mekameka mai i tētahi atu paerewa.Ehara ngā rerekētanga i te āhua noa: engari ko te teitei o te mekameka, te whānui o te pakiaka, te koki o te niho, me te ōwehenga o te whānui o te mekameka ki te teitei e whakatau ana i te nohoanga o te hononga mekameka i roto i te pōke wira.
Ko te DIN 766 te paerewa hononga-poto i whakawhanakehia tuatahitia mō te hiki whānui me ngā tono moana. Ko te tawhā tautuhi: ko te teitei he rite ki te 6 ngā wā o te diameter mekameka (6d). Mā tēnei mokowā hononga piripono ka whakanuia te horahanga pa o te mekameka-ki-wira, ka tohatoha te kawenga puta noa i ngā niho maha, ka whakaiti i te ahotea o ia niho. Ko te DIN 764 te paerewa hononga-roa e tata ana ki te 8 ngā wā o te diameter mekameka (8d). Mā te mokowā hononga roa ka whakaitihia te taumaha mekameka mō ia mita, ā, ka taea e te mekameka diameter nui ake te takai i ngā wira piripono. E ngana ana te ISO 16726 (me te ISO 67 e pā ana mō ngā mekameka here) ki te whakataurite i ēnei paerewa puta noa i te ao engari ka whakaurua he rerekētanga iti e pā ana ki te hototahitanga.
Ko te hua mahi o te whakaranu i ngā paerewa: ki te tāuta koe i tētahi mekameka DIN 766 ki runga i tētahi wira mekameka DIN 764 (tērā rānei), e kore ngā hononga mekameka e tino noho ki roto i ngā pute wira.Ka eke ngā hononga ki ngā taha o te pute kaua ki te papa o te pute, ka arotahi te kawenga ki te hononga raina kaua ki te hononga mata. Ko te mutunga mai he tere te pakaru o te taha o te pute, he rerekētanga o te hononga mekameka, ā, i ngā wā kino, ka peke te mekameka i te wā e piki ake ai te mekameka i waho o te pute i raro i te kawenga. Nāku ake i whakahaere ngā rangahautanga pūtāhui i reira ko te pūtake o te pakaru kino o te wira mekameka ko te mekameka DIN 764 i hokona e te kaiwhakahaere waka hei whakakapi i te mekameka DIN 766 kua tawhito nā te mea "he rite te whānui." E ai kiNgā tuhinga paerewa DIN, ahakoa ngā mekameka he rite te diameter ingoa (hei tauira, 16mm) mai i ngā paerewa rerekē, he rerekē ngā whakaritenga āhua o te pute.
Ngā Kaupapa Taketake o te Āhuahanga o te Wira Mekameka: Te Diameter o te Pitch, te Diameter o Waho, me te Diameter o te Pūtake
E toru ngā diameter matua o te wira mekameka (e kiia ana ko te wildcat, ko te chain sprocket rānei): te diameter pitch (Dp), te diameter o waho (Da), me te diameter pakiaka (Df).Ko te whānui o te piko ko te whānui o te porowhita ariā e honoa ai ngā hononga mekameka i a rātou e takai ana i te wira — ko te whānui mahi tēnei e whakatau ana i te tere mekameka mō tētahi RPM wira kua hoatu. Ka inehia te whānui o waho puta noa i ngā pito o ngā niho, ā, koinei te whānui nui rawa atu o te wira. Ka inehia te whānui o te pakiaka puta noa i te raro o ngā pōke i waenganui i ngā niho.Ka tatauhia te whānui o te papa tākaro penei i a Dp = P / sin(180/Z), ko P te papa tākaro o te mekameka (te mokowā hononga) ā, ko Z te maha o ngā pute (niho) i runga i te wira.Mō te mekameka DIN 766 he 16mm te whānui me te ōwehenga o te piko 6:1, ko te piko he 96mm, ā, ko te Dp = 96mm mō te wira 5-pōkete / sin(36 nekehanga) = 163.5mm.
E toru ngā āhuatanga matua o te pute: te whānui o te pute (me uru ki te whānui o te hononga mekameka me te āputa 0.5-1.5mm), te hōhonu o te pute (me uru ki te whānui o te hononga me te 1-2mm hei āputa paru), me te koki o te papa pute (me ōrite tonu ki te koki o te papa mekameka hei ārai i te kore taurite o te hononga-ki-pute).Ko te whānui o te pute te ine tino nui — ka piri rawa, ā, ka herea te mekameka i te wā e mau ana; ka tino wetekina rawa, ā, ka kopikopiko te mekameka ki te taha, ka kore e ōrite te pakaru o ngā niho.Ko te whānui paerewa o ngā pute mō ngā wira wini punga moana he +0.3mm ki te +0.8mm i runga ake i te whānui hononga mekameka ingoa.
Ngā Whakatakotoranga o te Mekameka DIN 766: Te Paerewa Hononga-Poto e Whakamahia ana i roto i ngā Whakamahinga Moana o Ūropi
Ko te DIN 766 te paerewa mekameka matua mō ngā wini punga moana nō Ūropi, ā, ko te nuinga o ngā wini punga Yining Hydraulic te paerewa i hangaia mō ngā mākete o Ūropi me te Rawhiti o Waenganui.E whakamārama ana te paerewa i te whanaungatanga i waenga i te diameter mekameka (d) me ngā ine hononga: te teitei (t) = 6d, te whānui o roto (b1) = 3.5d mō ngā rahi mekameka moana noa. Mō te mekameka DIN 766 16mm: te teitei = 96mm, te whānui o roto = 56mm, te roa o roto = 80mm. Ko te ātete ki te teitei ko +0.033d — ko te tikanga mō te mekameka 16mm, ko te ātete teitei ko +0.53mm puta noa i te hononga.
Ko te hoahoa o te mekameka wira mō te DIN 766 me whai pute e uru ana ki te kōtaha hononga katoa: ka noho he hononga whakapae ki roto i te pute me tōna tuaka roa e hangai ana ki te tuaka wira, ko te hononga poutū (e hono ana i ngā hononga whakapae tata) ka haere mā roto i te āputa i waenganui i ngā niho.Me whakarato te kōtaha niho i te ātea e tika ana kia uru ai te hononga poutū ki roto, ki waho hoki i te pute, me te kore e whakararuraru i te hurihuri o te wira.Yining Hydraulic, kua hangaia ā mātou wini punga raupapa IYM me te āhua pōke DIN 766 hei taunoa, me ngā āhua pōke DIN 764 me ISO e wātea ana hei kōwhiringa kua tohua. He mea mīhini te wira mekameka mai i te maitai koranu 42CrMo, kua tineia, kua whakamaroketia ki te HRC 45-50, me ngā taha niho whakapakeke-whakauru ki te HRC 55-58 hei ātete ki te kakahu.
Ngā Whakatakotoranga o te Mekameka DIN 764: Te Paerewa Hononga-Roa mō ngā Whakamahinga Diameter Mekameka-Teitei
E whakatau ana te DIN 764 i tētahi ōwehenga roa ake o te piko-ki-te-diameter (8d) ki te whakaritea ki te DIN 766 (6d), ka puta he mekameka e 33% te roa ake mō ia hononga mō te diameter mekameka ōrite.E rua ngā mahi a tēnei anga roa ake: ka whakaiti i te taumaha o te mekameka mō ia mita (ko te iti o ngā hononga mō ia mita he iti ake te taumaha maitai), ā, ka taea e te mekameka te takai i ngā wira iti ake te whānui (ka taea e te hononga roa ake te hono atu i runga i tētahi piko piri me te kore e herea). Mō ngā tono e tika ana kia mau te wini punga ki te mekameka whānui nui (20mm+) engari he iti te wāhi mohoao o te waka, ko te āhua anga roa o te DIN 764 te whiringa pai.
He rerekē te āhua o te pute wira mekameka DIN 764 i te DIN 766: he roa ake te pute (hei whakauru i te hononga roa ake), he pāpaku ake (nā te mea he iti ake te koi o te koki hononga e tomo ana ki te pute), ā, he tuwhera ake te āhua o te niho kia mārama ai te hononga poutū roa.He mahanga hokohoko noa: I ētahi wā ka whakahuahia e ngā kaihanga Hainamana te "wira mekameka paerewa DIN" me te kore e tohua te 766, te 764 rānei, me te whakaaro kei te hiahia te kaihoko ki te taunoa ā-rohe (ko te DIN 764 te tikanga i te mākete Haina).Ka whiwhi te kaihoko i tētahi wira DIN 764 mō tā rātou mekameka DIN 766 me ngā mata kore hototahi i te wā tāutanga. Ka tino taunaki ahau kia tohua te paerewa me te diameter mekameka tika i runga i te ota hoko, kaua e whakawhirinaki ki te kupu "paerewa." Mō iaISO 16726:2018mō ngā whakatakotoranga o te wira mekameka here, me tohu mārama te paerewa o te mekameka paerewa me te diameter ki runga i te wira tonu.
Ngā Wira Mekameka ISO 16726: Te Rerekētanga o te Paerewa o te Ao mai i ngā Putanga DIN
Ko te ISO 16726 (Hangarau kaipuke me te moana — Ngā wira mekameka mō ngā mekameka punga hononga-tītaha) te paerewa ā-ao e whai ana kia whakakotahi i te DIN, JIS, me ngā whakaritenga wira mekameka ā-motu i raro i te anga kotahi ā-ao.E kapi ana te paerewa ISO i ngā diameter mekameka mai i te 12.5mm ki te 162mm (te whānuitanga katoa e pā ana ki ngā kaipuke arumoni), ā, e tohu ana i te āhua o te pute, ngā whakaritenga rauemi, me ngā tikanga whakamātautau. Ko te rerekētanga matua mai i te DIN: E tohu ana te ISO 16726 i ngā ātete pute kikī ake — +0.3mm vs te +0.5mm noa o te DIN — ko te tikanga ka whakaaetia e te wira mekameka e tutuki ana i te ISO te mekameka DIN (he iti ake te rahi o te mekameka i te pute), engari kāore pea te wira ātete DIN e tutuki i ngā paearu whakaae ISO.
Mō te hoko mahi: he kōwhiringa haumaru te wira mekameka ISO 16726 hei whakamahi me te mekameka DIN 766 o te diameter ingoa ōrite.nā te mea kei roto te pute ISO i te awhi manawanui DIN i te taha piri. He morearea te taha whakamuri — te whakamahi i te wira DIN me te mekameka ISO — nā te mea ka hangaia pea te mekameka ISO ki te manawanui piri ake, ā, ka kore pea e ranea te ātea o te pute wira DIN, ka herea i ngā huringa 50-100 tuatahi i te mea ka pakaru te mekameka me te wira tetahi ki tetahi. IYining Hydraulic, ka hangaia e mātou ngā wira mekameka kia rite ki te paerewa ISO 16726 hei tūāpapa, me te DIN 766 me te DIN 764 hei kōwhiringa kua tohua ina hiahia te kaiwhakahaere kaipuke kia ōrite ki te rārangi mekameka o nāianei.
Te Pakari o ngā Rauemi me te Maimoatanga o te Mata: He aha te Hiranga o te Reiti Pakaru o te Wira Mekameka i te Utu
Ko te wira mekameka te wāhanga tino pakaru i roto i te pūnaha wini punga nā te mea ko ia huringa whakaara/whakaheke he pānga reti whakarewa-ki-te-whakarewa i waenga i ngā hononga mekameka me ngā pute wira i raro i te kawenga.Ko ngā whakatakotoranga rauemi — te kounga o te maitai koranu, te tukanga maimoatanga wera, me te tikanga whakapakeke mata — e whakatau tika ana i te roa o te mahi a te wira, ā, he haumitanga kino te wira e 20% te iti iho i te tīmatanga engari ka pakaru i roto i te 3 tau kaua ki te 10 tau.
| Whakatakotoranga Rauemi | Te Pakari Matua | Te mārō o te mata | Te Ora Ratonga Noa | Utu Whakatairanga |
|---|---|---|---|---|
| 42CrMo, kua tineia + kua whakamaroketia anake | HRC 35-40 | HRC 35-40 (kākahu ōrite) | 3-5 tau | Pūtake |
| 42CrMo, Q+T + ngā niho whakapakeke whakapūmau | HRC 45-50 | HRC 55-58 (niho) | 8-12 tau | +15-20% |
| 42CrMo, Q+T + nitride | HRC 45-50 | HV 700-900 (pouaka 0.3mm) | 10-15 tau | +25-30% |
| AISI 4340, Q+T + whakapūmautanga whakapakeketia | HRC 48-52 | HRC 58-62 (niho) | 12-18 tau | +40-50% |
Ko te whakapakeketanga o ngā taha o ngā niho te wāhi pai rawa atu mō ngā wira mekameka wini punga.Mā te tukanga nei ka whakamahana, ka tinei hoki i ngā mata e pā ana ki ngā niho, ka hangaia he anga pakari, ātete ki te pakaru (HRC 55-58, hohonu 2-4mm) me te pupuri tonu i te matua pakari, ātete ki te pānga. He mea nui te pakari o te matua — mēnā ka whakapakeketia te wira katoa ki te HRC 55+, ka pakarukaru, ka ngawari hoki te whati i te pānga ina mau te mekameka i raro i te kawenga ru. IaASTM A391Ko ngā whakatakotoranga mekameka maitai koranu, ko te huinga o te pakeke o te mata mō te ātete ki te kakahu me te pakari matua mō te ātete ki te pānga te huarahi hangarau paerewa mō ngā wāhanga pūnaha mekameka moana.
Te maimoatanga mata hei tiaki i te waikura: te paninga konutea phosphate (paparanga turanga) ā, muri iho ko te peita moana epoxy (te matotoru o te kiriata maroke 200-300 micron) e whakarato ana i te 5-8 tau o te tiakitanga waikura i roto i ngā taiao rehu tote. Mō ngā papaaho me ngā kaipuke o waho e mahi ana i te rohe tauhiuhi, ko te tiakitanga anode patunga tapu tāpiri (ngā anode konutea, konumohe rānei e herea ana ki te whare wira mekameka) ka roa ake te tiakitanga ki te 10-15 tau.Ko te utu pikinga mō te tiaki i te waikura — tata ki te US$80-120 mō ia mekameka wira — tata ki te 0.5% o te utu mō te whakakapinga o te wira i mua i te wā nā te pakaru o te waikura e hiahia ana kia wetewetehia katoatia te wira me te tango atu mā te kerēne. At Yining Hydraulic, ko tā mātou whakatakotoranga wira mekameka paerewa he 42CrMo Q+T me ngā niho whakapakeke-whakauru me te paninga moana epoxy — te iti rawa e taunakihia ana e mātou mō tetahi tono wini punga moana.
Ngā Pātai Auau
- Q1: He aha te rerekētanga i waenga i ngā whakaritenga mekameka DIN 766 me te DIN 764?
- E tautuhia ana e te DIN 766 ngā mekameka hononga-poto me te piko = 6d (te mokowā hononga piri mō te pa nui o te wira). E tautuhia ana e te DIN 764 ngā mekameka hononga-roa me te piko = 8d (33% hononga roa ake, mama ake te taumaha mō ia mita, kaha piko piri ake). He rerekē te āhua o te pute wira i waenga i ngā paerewa e rua, ā, kāore ngā mekameka e hototahi ana i waenga i ngā wira 766 me 764.
- P2: Me pēhea te ine i te whānui o te wira mekameka hei manatoko i te hototahitanga ki taku mekameka?
- Diameter o te papa (Dp) = P / sin(180/Z), ko P te papa mekameka (te mokowā hononga) ā, ko Z te maha o ngā pute i runga i te wira. Inehia puta noa i te wira i te wāhi e honoa ai ngā hononga mekameka ki roto i ngā pute — koinei te diameter mahi, ehara i te diameter o waho puta noa i ngā pito niho. Manatokohia mā te caliper ine i ngā pokapū papa pute, ehara i te pito niho.
- Q3: He aha te pakeke o te rauemi e hiahiatia ana mō ngā wira mekameka wini punga i roto i ngā taiao moana?
- Whakatakotoranga iti rawa: maitai koranu 42CrMo, kua tineia, kua whakamaroketia ki te pakeketanga matua HRC 45-50, me ngā taha niho kua whakapakeketia ki te HRC 55-58 (hohonutanga 2-4mm). Mā tēnei huinga ka ātete ki te kakahu o te mata me te pakari o te pānga o te matua. Ko ngā wira ngohengohe (i raro iho i te matua HRC 40) e whakaatu ana i te kakahu pute e taea te ine i muri i te 500-800 huringa i roto i ngā āhuatanga rehu tote.
- P4: Ka taea te whakamahi i te wira mekameka DIN 764 me te mekameka DIN 766 i ngā wā ohorere?
- Kāo. He roa ake, he pāpaku ake ngā pōke o ngā wira DIN 764 i hangaia mō ngā mekameka piko 8d. Kāore te mekameka DIN 766 (piko 6d) e tino noho ki roto i ēnei pōke, ka hanga he hononga rārangi ki ngā taha o te pōke, kaua ki te hononga mata puta noa i te papa o te pōke. Ka tere te pakaru o ngā taha o te pōke, ā, ka tūpono te peke o te mekameka i raro i te kawenga. Ka taea e te kore ōritenga paerewa te here i te mekameka i roto i te 50-100 huringa.
- Q5: He aha te maimoatanga mata e whakaroa ana i te roa o te ora o te mekameka wira i roto i ngā taiao moana rehu tote?
- Mā te paninga turanga konutea phosphate me te peita epoxy moana (200-300 micron DFT) ka tiakina te waikura mō te 5-8 tau. Mō ngā tono ki tai/rohe tauhiuhi, tāpirihia he anode patunga tapu (konutea, konumohe rānei) kua whakapurua ki te whare wira mō te tiakitanga mō te 10-15 tau. Ko te utu maimoatanga mata (US$80-120 mō ia wira) he tata ki te 0.5% o te utu whakakapinga wawe nā te waikura.
