Ko te whakawāteatanga o te pikau hurihuri ko te nui rawa o te mahi e mau ana tetahi mowhiti ki te tuunga me tetahi atu ki te ahunga torotoro, axial ranei.Ko te nui o te mahi i te taha o te radial e kiia ana ko te radial clearance, ko te nui o te mahi i te taha o te axial ka kiia ko te axial clearance.I te nuinga o te korero, ko te nui ake o te whakamaarama radial, ka nui ake te maatanga axial, me te rereke.E ai ki te ahua o te kawe, ka taea te wehea te waatea ki nga momo e toru e whai ake nei:
I. Whakaaetanga taketake
Whakakore utu i mua i te whakaurunga o te kawe.Ko te waatea taketake ka whakatauhia e te tukatuka me te huihuinga a te kaiwhakanao.
2. Tāutahia te whakawātea
Kei te mohiotia ano ko te whakamaarama pai, ko te whakawātea i te wa i whakauruhia ai te papa me te rakau me te whare kawe engari kaore ano kia mahi.He iti ake te whakamaarama o te whakaurunga i te waahi tuatahi na te whakaraeraetanga o te whakaurunga, te whakanui ake i te mowhiti o roto, te whakaheke i te mowhiti o waho, te rua ranei.
3. Whakaaetanga mahi
I te wa e mahi ana te whanau, ka piki ake te pāmahana mowhiti o roto ki te teitei me te toronga waiariki ki te teitei, kia heke iho te waatea o te whanau.I te wa ano, na te paanga o te utaina, ka puta te rerekeetanga elastic i te waahi whakapiri i waenga i te tinana hurihuri me te riihi, ka piki ake te waatea o te kawe.Mena he nui ake, he iti ake ranei te waahi mahi o te kawe i te whakaeatanga whakapuru e whakawhirinaki ana ki te awenga whakakotahitanga o enei mea e rua.
Kaore e taea te whakatika, te wetewete ranei etahi o nga pire hurihuri.E wātea ana i roto i nga tauira e ono, mai i te 0000 ki te 5000;He momo 6000 (nga koki whakapiri koki) me te momo 1000, Momo 2000 me te Momo 3000 me nga kohao kohanga i roto i te mowhiti o roto.Ko te whakakorikori whakapuru o enei momo awhi hurihuri, i muri i te whakarereketanga, ka iti ake i te waatea taketake.I tua atu, ka taea te tango i etahi waahi, ka taea te whakatika i te waatea.E toru nga momo o nga tohu: Momo 7000 (tapered roller bearing), momo 8000 (thrust ball bearing) me te momo 9000 (thrust roller bearing).Karekau he whakawātea taketake i roto i enei momo peara e toru.Mo te momo 6000 me te momo 7000 o nga roopu hurihuri, ka whakahekehia te waahi radial ka whakaitihia ano hoki te waahi o te axial, me te rereke, i te mea mo te momo 8000 me te momo 9000 rolling bearings, ko te waahi o te axial anake he mea tino nui.
Ko te whakamohiotanga tika e whakahaere ana i te mahi noa o te kawe hurihuri.He iti rawa te whakawātea, ka piki ake te pāmahana o te hurihanga, kaore e taea te mahi noa, kia mau ai te tinana hurihuri;He nui te waatea, he wiri taputapu, he haruru okeoke.
Ko te tikanga tirotiro radial clearance e whai ake nei:
I. Tikanga tairongo
1. Ma te ringa hurihuri o te ringa, me maeneene te kawe me te ngawari me te kore e piri me te astringency.
2. Ruperupea te mowhiti o waho o te pikaunga ma te ringa.Ahakoa ko te 0.01mm anake te waatea o te radial, ko te nekehanga axial o te pito o runga o te kawe he 0.10-0.15mm.Ka whakamahia tenei tikanga mo te rarangi poi poipoi rarangi kotahi.
Tikanga ine
1. Tirohia me te whakau i te waahi kawenga teitei o te kawe hurihuri me te kaitao, whakaurua he kaikorero i waenga i te tinana hurihuri 180° me te mowhiti o waho (roto), a ko te matotoru tika o te kaera ko te whakamaarama radial o te kawe.Kei te whakamahia nuitia tenei tikanga i roto i nga arai whakahuri-whaiaro me nga peera roera porotakaroa.
2, tirohia me te tohu waea, tuatahi tautuhi i te tohu waea ki te kore, katahi ka hikina te whakakai o waho o te mowhiti, ko te panui tohu waea ko te waatea o te radial o te whanau.
Ko te tikanga tirotiro mo te whakawātea axial e whai ake nei:
1. Tikanga tairongo
Tirohia te whakawātea axial o te puri hurihuri ma to maihao.Me whakamahi tenei tikanga ina puta te pito o te kakau.Ina katia te pito o te rakau, kaore ranei e taea te tirotiro e nga maihao mo etahi atu take, tirohia mehemea he ngawari te hurihanga o te rakau.
2. Tikanga ine
(1) Tirohia me te kaikawe.Ko te tikanga mahi he rite tonu ki te tirotiro i te whakawātea radial me te feeler, engari ko te whakawātea axial me
C = lambda/hara (2 beta)
Ko c -- whakawātea axial, mm;
-- Te matotoru ine, mm;
-- Bearing cone Koki, (°).
(2) Tirohia me te tohu waea.I te wa e whakamahia ana te kaapapa ki te whakawhiti i te hiku neke ki nga tuunga tino nui e rua, ko te rereketanga o te panui tohu waea ko te maatanga axial o te kawe.Heoi, kia kaua e nui rawa te kaha e pa ana ki te porowhita, ki te kore ka rerekee te anga, ahakoa he iti rawa te rerekee, ka pa ki te tika o te whakawātea axial ine.
