Muzvitoro zvakawanda, kana chirukwa chapera, vanhu vanochitora serombo rakaipa. Rimwe zuva muchina uyu uri kucheka zvakanaka, zuva rinotevera unoridza aramu, woita ruzha rusinganzwisisike, kana kuti hauchadhuri zvakare. Mumwe munhu anovhura kabati, anonzwa chimwe chinhu chakatsva, uye mhedzisiro inouya nekukurumidza:
'Chirukwa chakafa. Zvinoitika.'
Zvinoita sezvine musoro—asi kazhinji hazvina kunaka.
Mushure mekubvarura mazana ezvirukwa zvakakundikana mumakore apfuura, ndinogona kukuudza izvi nekuvimba: maspindle haakundike kamwe kamwe . Vanokundikana zvishoma nezvishoma, chinyararire, uye nekufanotaura zvikuru. Kuparara kwekupedzisira — utsi, rwendo rwekupaza, shaft yakakiyiwa — chinongova chitsauko chekupedzisira chenyaya yave ichiitika kwemavhiki kana mwedzi.
Kare chirukwa 'chisati chafa,' chave kutokumbira rubatsiro. Tembiricha shoma inowedzera. Subtle vibration. Imwe ruzha rushoma pakakwirira RPM. Pamwe iyo VFD yazvino inokwira kumusoro, asi hapana anozviona. Aya masaini ari nyore kufuratira kana kugadzira kuchida kuramba kuchifamba. Asi mukati mechirukwa, kukuvadzwa kuri kutowanda—mabhengi akapfeka, kuchembera kwekudzivirira, mafuta okuzora ari kuputsika.
Pakazosvika nguva iyo spindle yakamira chaizvo, kukundikana hakusisiri mubvunzo wekuti , riini chete.
Chinoshamisa vanhu vazhinji hakusi kuti zvirukwa zvinokundikana — asi kuti zvinodzokororwa sei kukundikana . Mafekitari akasiyana. Mhando dzakasiyana. Michina yakasiyana. Vashandisi vakasiyana. Asi kana iwe ukavhura chirairo uye uchitarisa humbowo, midzi zvikonzero zvinenge zvakangofanana.
Kakawanda, kukundikana kwespindle kunouya kune matambudziko matatu chete:
Matambudziko ekuzora
Matambudziko emagetsi
Kuremedza spindle usingazvizive
Ndizvo. Kwete zvikonzero gumi. Kwete zvisinganzwisisike zvirema zvefekitari. Kwete 'rambo rakaipa'
Mapiritsi mazhinji haakundikane nekuti haana kunaka — anokundikana nekuti kuzora mafuta kwainge kwakashata, kwakasvibiswa, kusakwana, kana kusanzwisiswa zvachose. Mazhinji mhepo inomonereka haitsva nekuti mhangura yakaipa-inopisa nekuda kwekusagadzikana kweVFD marongero, kusaenzana kwevoltage, kupisa, kana kudzvanya kushushikana nekufamba kwenguva. Uye zvirukwa zvizhinji hazvina 'kunyanya kusimba' - zvinongosundirwa kupfuura miganhu yavo chaiyo yekushanda, zuva nezuva, kusvikira chimwe chinhu chapa.

Pakazosvika nguva iyo spindle yakazobata kana kufambisa VFD, kukundikana kunotaridzika kamwe kamwe , asi yaive mhedzisiro yemwedzi yekushungurudzwa kusingaonekwe. Kunzwisisa uye kudzora mutoro, kumhanya, chiyero chezvishandiso, uye kumhanya ndiwo mutsauko pakati pechipindo chinotora makore maviri kusvika matatu uye chinokundikana mumwedzi mishoma.
Kunyange chirungiso chakanyatsozorwa uye chine mutsindo wemagetsi chinogona kupfekwa nekufamba kwenguva nemasimba chaiwo achakagadzirirwa kubata. Kucheka mitoro hakudzivisiki—asi masimba asingadzorwi zvakanaka vaurayi vakanyarara.
Vazhinji vashandisi havafungi maererano negwara rekuremerwa , asi ma spindles anoita.
Radial mitoro - masimba epadivi kubva pakugaya, kutsveta, kana kutenderera - kazhinji ndiwo mhondi huru, kunyanya pa RPM yakakwirira. Vanosundidzira mabearings kudivi, uko zvinhu zvinokunguruka zvisingarevi kutakura kusagadzikana. Kuneta kunovaka chinyararire, chimurenga chimwe panguva.
Axial mitoro - kudonha, kuchera, kana kucheka mapendekete anorema - anodzvanya mabearings paakisi yawo. Kana iyo spindle isina kugadzirwa inorema axial simba, kushushikana uku kunoderedza kubereka hupenyu zvakanyanya.
Hapana mhando yemutoro ine ngozi. Dambudziko rinomuka kana mitoro ikadarika chiyero che spindle, zvakangofanana kana kudzokororwa . Kunyangwe 'zvakajairika' kucheka kunoitwa nehasha kunogona chinyararire nepakati kubereka hupenyu mumavhiki kana mwedzi.
Kudengenyeka hakusi ruzha runogumbura chete—chiratidzo chekukuvara kuri kuitika . Kana vibration yatanga:
Kupfeka kupfeka kunova kusaenzana
Mafirimu ekuzora anoparara nekukurumidza
Kupisa kunokwira mukati mechirukwa
Kururama kunodonha
Uye chikamu chakaipisisa? Vibration inodya yega . Bere rakakuvadzwa zvishoma rinodedera zvakanyanya, izvo zvinorikuvadza nekukurumidza. Kukasiiwa kusingadzorwi, kusaenzana kuduku kunova ngwavaira munhau yamazuva kana kuti mavhiki.
Ndakaona maspindle aiita seakanaka pabepa achitadza kukurumidza kana vibration yabata, kunyangwe pasina mitoro yakawandisa. Kuregeredza kudengenyeka kwekutanga kwakafanana nekuregeredza mitswe yekutanga mudhamu.
Vashandi vanowanzopomera kupera kwakashata pamucheki, nzira yekushandisa, kana mitengo yekudya - uye dzimwe nguva vakarurama. Asi muzviitiko zvakawanda, kupera kwakashata kwepamusoro ndiyo chiratidzo chekutanga chinooneka chekupfeka kubereka kwe spindle.
Micro-vibration kubva kukuvadzwa kwekutanga kunoratidza pane chikamu kare ruzha, maalarm, kana tembiricha spikes isati yaonekwa.
Kukurukurirana kudiki, mitsetse, kana kusawirirana kwemavara kungaite kunge kushoma, asi zviratidzo zvekuyeverwa kuti chirukwa chiri kushushikana.
Kana iwe ukaona zvisingatsanangurike nyaya dzekupedzisa, usazvifuratire. Ongorora chirungiso chisati chakwira kusvika pakutadza zvachose.
Spindles kashoma kukundikana pakarepo. Kukundikana kwakawanda kunoitika zvishoma nezvishoma uye kunofanotaurwa —kana uchiziva zvokutsvaka. Vashandi vane ruzivo vanodzidza 'kuverenga' masiginecha akajeka nguva refu chiutsi kana maaramu asati aoneka.
Chirunga chine hutano chine ruzha rwakafanana, rwakatsetseka . Kuchinja kupi nokupi munzwi iroro inyevero. Ruzha rweyambiro rwakajairika runosanganisira:
Kuchemerera kana kurira kwepamusoro-soro pamhepo chaiyo
Low-frequency rumbling yanga isipo kare
Kugaya kana kudzvanya
Vafambisi vanowanzoshinyira vachiti, 'Zvinogara zvichinzwika saizvozvo.' Kutaura zvazviri, manzwi matsva anenge agara anoratidza kuti chimwe chinhu chachinja—mabhengi, mafuta okuzora, kana kuti chiyero chezvishandiso. Usambofa wakadzinga ruzha rusina kujairika; ndivo vanorukwa vari kuedza kukuudza chimwe chinhu nguva isati yakwana.
Imwe tembiricha kuverenga kashoma kutaura nyaya yakazara. Chipindo chinomhanya pa45°C chingava chakanaka—asi kana chaimbomhanya pa35°C , kuwedzera kwe10°C ikoko kunokosha.
Kamwe kamwe kana zvishoma nezvishoma tembiricha inokwira inogona kuratidza:
Lubrication degradation
Kuwedzera kutakura mutoro
Misalignment kana kusaenzana
Kushushikana kwemagetsi mukati memota
Trend monitoring ndiyo yakakosha. Kutarisa maitiro anoita spindle nekufamba kwenguva kunokupa iwe mukana wekutanga kupindira-kupisa kusati kwakonzera kukanganisa zvachose.
Michina yese inodedera kusvika pamwero wakati, asi kuwedzera vibrate hakuna kumbobvira kwakajairika.
Nzira itsva yekutaura apo yakanga isati yambovapo - kushandisa chishandiso chimwe chete, zvinhu, uye chirongwa - mucherechedzo mutsvuku.
Kunyangwe kuwedzera kushoma kwekudengenyeka kunogona kuratidza kupfeka kwekutanga kutakura kana kusaenzana kwerotor.
Kusiiwa isina kucheneswa, vibration inozvidyisa: mabhengi akakuvadzwa anogadzira kudedera kwakawanda, uko kuno mhanyisa kubereka kukuvara.
Machina haawane 'chembere uye shaky' pasina chikonzero. Kutanga kuona vibration ndiyo imwe yenzira dzakavimbika dzekuwedzera hupenyu hwe spindle.
Spindle dzimwe nguva dzinopa zviratidzo zvisinganzwisisike pamberi pekukundikana kwenjodzi:
Yakaderedzwa torque pasi pemutoro wakafanana
Kuchinja-chinja kana kusagadzikana RPM
Kusapindirana kwekucheka kwekuita kana kupera kwepamusoro
Idzi shanduko duku dzinowanzoonekwa mavhiki asati akundikana zvachose . Vashandi vanovaziva nekukurumidza vanogona kutora matanho ekugadzirisa-kugadzirisa mitengo yekudya, kutarisa mafuta, kana kuongorora mamiriro emagetsi nemakanika - spindle isati yasvika pakusadzoka.
Nekubatanidza ruzha, tembiricha, vibration, uye maitiro ekuita , vashandisi vane ruzivo vanogona kazhinji kubata maspindle matambudziko mavhiki pamberi , kudzivirira inodhura nguva yekudzikira uye kudzivirira zvese spindle nezvikamu zvinogadzira.
Kunyangwe hazvo zvitoro zvakawanda zvichiziva kuti ma spindles anokundikana zvishoma nezvishoma uye nekufungidzira, kudzivirira kuchengetedza kunowanzo kumiswa . Zvikonzero zvacho zvinozivikanwa—uye zvinodhura.
Nhamba yekutanga chikonzero chekuchengetedza chinoregwa? Vashandisi uye mamaneja vanoona chinotenderera uye vanofunga kuti zvese zvakanaka:
'Ichiri kucheka, ko ibatei?'
Ndiyo nguva chaiyo apo kuchengetedza kunonyanya kukosha. Kumirira kutadza kuoneka kunovimbisa:
Kugadziriswa kwepamusoro kana kutsiva mari
Yakareba kugadzirwa kuderera
Kushungurudzika kwevashandisi, vatariri, uye vatengi zvakafanana
Maspindle haapi nyevero nenzira inocherekedzwa nevanhu vazhinji-inounganidza chinyararire kukuvadzwa kutozosvikira kutadza kwacho kwanyanya uye kuchidhura.
