Iyo slewing bearing mechanism ye tower crane inonyanya kuumbwa neslewing bear, slewing drive uye kumusoro uye kuzasi rutsigiro.Iyo tower crane slewing bearing assembly mukuita basa kazhinji haizove yakatsetseka kushanda uye ruzha runopfuura chiyero (chisina kujairika ruzha) kukanganisa.Munyori akabatanidza neruzivo rwake rwekushanda kubva kukuuraya, kuuraya michina uye kuuraya zvikanganiso zvakateerana, mukugadzira maitiro, kuongororwa kwegungano, kugadzirisa kwemidziyo uye zvimwe zvezvavanofunga uye mazano.

Tower crane inouraya mhete yekutadza kudzivirira matanho uye kugadzirisa

1.slewing mhete giya zvinodiwa

Iko kubata uye kukotama simba regiya pasi pekupedzisira uye kuneta mitoro yakaverengerwa uye yakasimbiswa zvinoenderana ne ISO6336-1: 2006, ISO6336-2: 2006 uye ISO6336-3: 2006 zvakateerana.Sf iri 1.48 uye iyo giya mesh clearance inogadziridzwa kune yepamusoro poindi yeradial inomhanya kunze kweiyo slewing inotakura giya pitch denderedzwa.Iko kucheneswa kwemazino kunowanzo kuve 0.03 kusvika 0.04x modulus, uye giya mesh kucheneswa kwepinion giya pane yese denderedzwa inoda kutariswazve mushure mekusunga kwekupedzisira kwekuuraya.

2. Slewing kutakura mukati lubrication
Mukushandiswa kwezuva nezuva kunofanirwa kuve nenguva, nenguva, zvinoenderana negwaro rekuraira rechikamu chimwe nechimwe zvinoenderana nemafuta, lubrication, lubrication cycle gadziriro yekuzora.Zvinoenderanabhora mheteinowanzozadzwazve maawa ega ega ekushanda, roller slewing ring inozadzwazve maawa makumi mashanu ega ega, kune guruva, hunyoro hwakanyanya, kusiyana kwekushisa kwenzvimbo yakakosha yekushanda kunofanirwa kupfupisa kutenderera kwekuzora.Kuzora kwega kwega kunofanirwa kuzadza nzira yekuzora kusvikira mafuta abuda, achizadza achitenderedza zvishoma nezvishoma bhero rekuita kuti girisi rizadzwe zvakaenzana.Nekuzadza gadziriso yemafuta ekuzora, inogona kuderedza kupokana pakati pegiya regiya, kudzikamisa chiyero chekupfeka chegiya regiya, kuumbwa kweiyo firimu remafuta kunogona kuitawo basa rekuvhundutsa kunyura mhete, kubvisa chikamu chesimba rekuzunguza rinogadzirwa. mukushanda.Pamusoro pezvo, iyo firimu yemafuta ekuzora inogona zvakare kuve yakanaka yekuzora inochenesa iyo friction pamusoro, kudzivirira ngura, uye kubvisa pesvedzero yesimbi zvidimbu pane friction pamusoro.Kuti uderedze ruzha rwekupokana mukushanda uye nekuwedzera hupenyu hwebasa rekutakura.

3.Kusimbisa mabhaudhi
Mabhaudhi ekubatanidza ekutakura uye ekumusoro uye ezasi slewing bearing anoiswa pasi peaxial pulsating mutoro mukuwedzera kune preload, izvo zvichaita kuti mabhaudhi atambanudzwe kana kubatana kwechiso kukanganiswa, zvichiita kuti mabhoti asununguke.Bolt joint yekusunungura preload haisviki painodiwa axial clearance inowedzera, inotenderedza muviri neinopidigura torque kutenderera, mujaho wemujaho nekushushikana kukuru kwekusangana, zvichikonzera kukuvara kwemujaho.Guta raive neQTZ 25 tower crane yekumusoro dhizaini inopidigura tsaona, chakananga chikonzero ndechekuuraya uye mabhaudhi ekumusoro anotakura mabhaudhi mumamiriro asina kutaurwa ebasa, zvichikonzera kuti boka remabhaudhi rimwe nerimwe, ritevedzwe pasi pezvakawanda kupfuura kutakura kwaro. kugona kweboka remabhoti.Izvi zvakakonzera chimiro chepamusoro cheshongwe (ine slewing bearing) ichiputsika kubva kune shongwe yekugadzira uye ichidonha pamusoro.Iyo slewing bearing bolt tightening uye kusarudzwa kwayo kwesimba kunokosha zvikuru.Naizvozvo, iyo slewing bearing bolt kusungirira uye kusarudzwa kwayo kwesimba kwakakosha.

4. Kuiswa uye Kushanda

Kuiswa kwechindori chekucheka kunofanira kusarudzwa nepamusoro-soro mabhaudhi, mabhaudhi uye nzungu dzinofanira kuenderana neGB3098.1 uye GB3098.2 zvinodiwa zvakajairwa zvinorambidza kushandiswa kwemawashi echitubu.Usati waomesa mabhaudhi anokwirisa, saizi yegiya meshing gadziriso (padivi pemvumo) inofanirwa kuitwa kuti ive nechokwadi chekuti bhiza rekuuraya uye pinion mesh kuzadzisa zvinodiwa.Simbisa mabhoti anosungirirwa anofanira kunge ari pa 180 °, ndege yekuisa inofanira kuva yakachena uye yakadzikama, isina burrs, shavings yesimbi uye mamwe marara, ndege inofanira kusangana nezvinodiwa.

Tower crane slewing ring iri kushanda kazhinji ichave yakatyoka mazino kutadza, saka shongwe crane iri kushanda inofanirwawo kufunga nezvekukanganisa kwemhepo pachindori chekuuraya, kana kupfuura iyo yakataurwa mhepo kushanda kana kumisa kushanda mushure mekunge crane boom isingakwanise kutenderera. zvakasununguka nemhepo, izvi zvinogona kukuvadza giya uye slewing kutakura kubatanidzwa kana kuuraya mhete, njodzi yakakomba ichaitika.Saka iyo shongwe crane mukugadzika uye kushanda inofanirwa kuita ongororo yakadzama.
