1. Kukuvadza chiitiko chekutakura kutakura

Mumakina akasiyana ekuvaka akadai semarori cranes uye ekuchera, mhete yekuuraya chikamu chakakosha chinopfuudza iyo axial mutoro, radial mutoro uye nguva yekunongedza pakati peinotendeuka uye chassis.

Mumamiriro ezvinhu akareruka, inogona kushanda zvakajairika uye kutenderera zvakasununguka.Zvisinei, kana mutoro unorema, kunyanya pahukuru hwekusimudza uye huwandu hwepamusoro, zvakaoma kuti chinhu chinorema chitenderere, kana kuti hachikwanisi kutenderera zvachose, kuitira kuti chibatire.Panguva ino, nzira dzakadai sekudzikisa huwandu, kugadzirisa zvinobuda, kana kufambisa chinzvimbo chechasisi dzinowanzo shandiswa kurereka muviri kubatsira kuona kutenderera kwechinhu chinorema uye kupedzisa kusimudza kwakarongwa uye mamwe maoperation.Naizvozvo, panguva yebasa rekugadzirisa, zvinowanzoonekwa kuti nhangemutange yemujaho wekubaya yakakuvadzwa zvakanyanya, uye mitswe yeannular padivi penzira yemujaho inogadzirwa kumativi ese emujaho wemukati uye yezasi nhangemutange pamberi pekushanda. nzvimbo, zvichiita kuti mugwagwa wepamusoro wemujaho uore mwoyo munzvimbo yakanyanya kusimbiswa., uye kubudisa radial cracks mukati mekuora mwoyo.

2. Hurukuro pamusoro pezvinokonzeresa kukuvadzwa kwemabheya ekuura

(1) Kupesvedzera kweiyo kuchengetedza chinhu Chimiro chekuuraya chinowanzo shandiswa pasi pemamiriro ekumhanya kwakadzika uye mutoro unorema, uye kutakura kwayo kunokwanisa kuwanzo kuratidzwa ne static capacity, uye iyo yakayerwa static kugona inonyorwa seC0 a.Iyo inonzi static capacity inoreva simba rekutakura rekutakura kwekutakura kana deformation yekusingaperi yemujaho δ inosvika 3d0 / 10000, uye d0 ndiyo dhayamita yechinhu chinoputika.Iko kusanganiswa kwemitoro yekunze inowanzomiririrwa neyakaenzana mutoro Cd.Chiyero cheiyo static kugona kune yakaenzana mutoro inodaidzwa chengetedzo factor, inotaridzwa sefs, inova ndiyo nheyo huru yekugadzira uye kusarudzwa kwemabhengi ekuura.

Kana iyo nzira yekutarisa iyo yakanyanya kusangana kushushikana pakati pe roller uye nhangemutange inoshandiswa kugadzira kutakura kutakura, mutsara wekubata kushushikana [σk line] = 2.0 ~ 2.5 × 102 kN / cm inoshandiswa.Parizvino, vazhinji vanogadzira vanosarudza uye vanoverenga rudzi rwekurovera kutakura zvichienderana nehukuru hwemutoro wekunze.Zvinoenderana neruzivo rwuripo, kushushikana kwekubata kwekutakura kweiyo diki tonnage crane idiki pane iyo yakakura tonnage crane parizvino, uye chaiyo yekuchengetedza chinhu chakakwira.Iyo yakakura iyo tonnage ye crane, iyo yakakura dhayamita yekutakura inouraya, yakaderera yekugadzirwa kwayo, uye yakaderera iyo yekuchengetedza chinhu.Ichi ndicho chikonzero chakakosha nei kuuraya kweiyo hombe-tonnage crane kuri nyore kukuvadza pane kuurayiwa kweiyo diki-tonnage crane.Parizvino, zvinotendwa kuti mutsara wekubata kushushikana kwekutakura kwecrane pamusoro pe40 t haifanirwe kudarika 2.0 × 102 kN/cm, uye chengetedzo haifanirwe kunge iri pasi pe1.10.

(2) Kupesvedzera kwekuoma kwechimiro cheturntable

Mhete yekuuraya chikamu chakakosha chinoendesa mitoro yakasiyana-siyana pakati peturntable uye chassis.Kuoma kwayo pachayo hakuna kukura, uye kunonyanya kuenderana nekusimba kweiyo chassis uye turntable inoitsigira.Tichitaura, chimiro chakanaka cheturntable chimiro checylindrical chine kusimba kwepamusoro, kuitira kuti mutoro uri paturntable unogona kugoverwa zvakaenzana, asi hazvibviri kubudirira nekuda kwekukwirira kwemuganhu wemuchina wose.Iyo inopera element yekuongorora mhedzisiro yeturntable inoratidza kuti deformation yeplate yepasi yakabatana neturntable uye kutakura kutakura kwakakura, uye kwakatonyanya kukomba pasi pemamiriro emutoro wakakura, izvo zvinoita kuti mutoro utarise pane. chikamu chiduku chema rollers, nokudaro kuwedzera mutoro wemupumburu mumwe.Dzvinyiriro yakagamuchirwa;kunyanya yakakomba ndeyekuti deformation yeturntable chimiro ichashandura mamiriro ekubatana pakati pe roller uye mujaho, zvakanyanya kuderedza kureba kwekusangana uye kukonzera kuwedzera kukuru kwekunetseka kwekusangana.Zvisinei, nzira dzekuverenga dzekubatanidza kushushikana uye simba rakagadzikana rinoshandiswa zvakanyanya panguva ino rinobva pane chirevo chokuti kutakura kwekuuraya kunosimbiswa zvakaenzana uye hurefu hwekusangana hunobudirira hwemupumburu ndeye 80% yehurefu.Zviripachena, chirevo ichi hachienderane nemamiriro chaiwo.Ichi ndicho chimwe chikonzero nei mhete yekuuraya iri nyore kukuvadza.

(3) Kufurira kwemamiriro ekurapa kupisa

Kugadziriswa kwehutano hwekutakura kwekutakura pachayo kunonyanya kukanganiswa nekugadzirisa kwekugadzira, axial clearance uye mamiriro ekugadzirisa kupisa.Chinhu chisingatarisirwi nyore pano ndechekuita kwemamiriro ekurapa kwekupisa.Zviripachena, kuti udzivise kutsemuka uye kudzikira pamusoro pemujaho, zvinodikanwa kuti pamusoro pemujaho panofanirwa kuve neyakaomarara yakaomarara kudzika uye kuomarara kwepakati mukuwedzera pakuoma kwakakwana.Zvinoenderana nedata rekune dzimwe nyika, kudzika kweiyo yakaomeswa jira remujaho kunofanirwa kuve kwakakora nekuwedzera kwemuviri unotenderera, iyo yakadzika inogona kudarika 6mm, uye kuoma kwepakati kunofanirwa kunge kwakakwira, kuitira kuti mujaho ugove nekupwanya kwepamusoro. resistance.Nokudaro, kudzika kwechigadziko chakaomeswa pamusoro pemujaho wekuuraya kutakura hakuna kukwana, uye kuoma kwepakati kwakaderera, izvo zvakare chimwe chezvikonzero zvekukuvadza kwayo.

3.Matanho ekuvandudza

(1) Kuburikidza nekuongororwa kwechinhu chinopera, wedzera zvakakodzera kukora kweplate yechikamu chekubatanidza pakati peturntable uye kutakura kutakura, kuitira kuti uvandudze kurongeka kweiyo turntable.

(2) Paunenge uchigadzira mabheji makuru-diameter ekuuraya, iyo yekuchengetedza chinhu inofanira kuwedzerwa zvakakodzera;zvakakodzera kuwedzera nhamba yema rollers inogonawo kuvandudza mamiriro ekubatana pakati pema rollers uye mujaho.

(3) Kuvandudza kururamisa kwekugadzira kwekutakura kutakura, kutarisa pakugadzirisa kupisa.Inogona kuderedza yepakati frequency quenching kumhanya, kuedza kuwana hukuru hwekuoma kwepamusoro uye kuoma kudzika, uye kudzivirira kudzima mitswe pamusoro penzira yemujaho.
