Mukugadzira maitiro eiyo inoteedzerwa undercarriage chassis yemuchina wekuvaka, bvunzo dzekumhanya dzinoda kuitwa pane chassis yese nemavhiri mana (kazhinji achireva sprocket, kumberi idler, track roller, yepamusoro roller) mushure memusangano inhanho yakakosha kuona kuvimbika uye kusimba kwechasisi. Aya anotevera mapoinzi akakosha ekutarisa panguva yekumhanya bvunzo:
I. Gadziriro pamberi pebvunzo
1. Chikamu chekuchenesa nekuzora
- Kunyatso bvisa zvisaririra zvegungano (zvakadai semarara esimbi nemafuta emafuta) kudzivirira tsvina kupinda mumudziyo uye kukonzera kusakara nekuda kwekukweshana.
- Wedzera yakakosha mafuta ekuzora (senge yakakwira-tembiricha yelithium-yakavakirwa girisi) kana mafuta ekuzora senge tekinoroji maratidziro kuti ave nechokwadi chekuti zvidimbu zvinofamba zvakaita semabhengi uye magiya anozorwa zvakakwana.
2. Kuiswa Kwazvo Verification
- Tarisa kushivirira kwegungano kwemavhiri mana (senge coaxiality uye parallelism), kuve nechokwadi chekuti vhiri redhiraivha rinopindirana nenjanji pasina kutsauka uye kuti kudhonzerana kwevhiri rinosangana neiyo dhizaini kukosha.
-Shandisa laser alignment chishandiso kana dial chiratidzo kuti uone kufanana kwekubatana pakati pemavhiri asingaite uye track link.
3. Basa Pre-kuongorora
- Mushure mekuunganidza chitima chegiya, tenderedza nemaoko kutanga kuti uone kuti hapana kudhumhana kana ruzha rusina kujairika.
- Tarisa kana zvikamu zvekuisa chisimbiso (senge O-mhete uye zvisimbiso zvemafuta) zviri munzvimbo kudzivirira kubuda kwemafuta panguva yekumhanya-mukati.
II. Key Control Points Panguva Yekuedza
1. Mutoro uye Operating Condition Simulation
- Staged Loading: Tanga nemutoro wakaderera (20% -30% yemutoro wakatemerwa) nekumhanya kwakaderera mudanho rekutanga, zvishoma nezvishoma uchiwedzera kusvika kuzere mutoro uye kuremerwa (110% -120%) mamiriro ekutevedzera mitoro yemhedzisiro inowanikwa mukushanda chaiko.
- Yakaoma Terrain Simulation: Misa mamiriro akaita semabumps, inclines, uye mativi materu pabhenji rekuyedza kuratidza kugadzikana kwevhiri system pasi pekunetseka kukuru.
2. Real-time Monitoring Parameters
-Kutarisisa Tembiricha: Infrared thermometers inotarisisa kukwira kwekushisa kwemabheri uye magiya mabhokisi. Tembiricha yakakwira zvisina kujairika inogona kuratidza kusakwana kwekuzora kana kukanganiswa kwefriction.
-Vibration uye Noise Ongororo: Kumhanyisa sensors kuunganidza vibration spectra. High-frequency ruzha runogona kunongedzera kune yakashata giya meshing kana kutakura kukuvara.
-Track Tension Adjustment: Dynamically tarisisa iyo hydraulic tensioning system yegumbo rinotungamira kudzivirira track kuti isanyanya kusununguka (kutsvedza) kana yakanyanya kusimba (kuwedzera kupfeka) panguva yekumhanya-mukati.
-Manzwi asina kujairika uye Shanduko: Tarisa kutenderera kwemavhiri mana uye kushushikana kwetrack kubva kumakona akawanda panguva yekumhanya-mukati. Tarisa kune chero shanduko dzisina kujairika kana manzwi kuti uwane nemazvo uye nekukasira nzvimbo kana chikonzero chedambudziko.
3. Lubrication Condition Management
- Panguva yekushanda kwechasi, tarisa kuzadza girisi panguva yakakodzera kudzivirira kuparara kwegirisi nekuda kwekupisa kwakanyanya; kune yakavhurika giya kufambisa, tarisa iyo mafuta firimu kufukidzwa panzvimbo yegiya.
III. Kuongorora uye Kuongorora mushure mekuedzwa
1. Pfeka Trace Analysis
- Bvisa uye ongorora mapeiri anokweshana (senge vhiri remavhiri, dhiraivha zino pamusoro), uye tarisa kana kupfeka kuri yunifomu.
-Abnormal kupfeka rudzi kutsunga:
- Pitting: kushomeka kwemafuta kana kusakwana kuoma kwezvinhu;
- Spalling: kuremerwa kana kupisa kurapwa kuremara;
-Kukwenya: tsvina inopindira kana kutadza kusimbiso.
2. Chisimbiso Performance Verification
- Ita bvunzo dzekumanikidza kuti utarise kuvuza kwechisimbiso chemafuta, uye tevedzera nharaunda yemvura ine madhaka kuti uedze guruva-risingabvumire mhedzisiro, kudzivirira jecha nemadhaka kupinda uye kukonzera kutadza kubereka panguva yekushandiswa kunotevera.
3. Kuyerwa zvakare kweChiyero Chinokosha
-Yeresa zviyero zvakakosha senge dhayamita yevhiri axle uye meshing clearance yemagiya kuratidza kuti haana kupfuura chiyero chekushivirira mushure mekumhanya.
IV. Special Environmental Adaptability Testing
1. Yakanyanya Temperature Testing
-Simbisa kugona kwekudzivirira-kurasikirwa kwegirisi munzvimbo dzepamusoro-tembiricha (+50 ℃ uye pamusoro); edza brittleness yezvinhu uye kutonhora kwekutanga kuita munzvimbo dzakaderera-tembiricha (-30 ℃ uye pazasi).
2. Corrosion Resistance uye Wear Resistance
- Munyu wekupfapfaidza bvunzo inotevedzera pamahombekombe kana deicing agent nharaunda kuti vatarise kugona kwe-anti-corrosion yejasi kana plating layer;
- Dust bvunzo dzinoratidza kudzivirira kwezvisimbiso kubva pakupfeka abrasive.
V. Kuchengetedza uye Kunyatsogadzirisa
1. Kuchengetedza Kuchengetedza Matanho
- Bhenji rekuyedza rakashongedzerwa nekukurumidzira mabhureki uye zvipingamupinyi kudzivirira tsaona dzisingatarisirwe dzakadai seakatyoka shaft uye mazino akatyoka panguva yekumhanya-mukati.
-Vashandi vanofanirwa kupfeka giya rekudzivirira uye varambe vari kure nepamusoro-zvinotenderera zvikamu.
2. Data-inotungamirirwa Optimization
-Nekumisa modhi yekubatanidza pakati pekumhanya-mumaparamita uye hupenyu kuburikidza ne sensor data (senge torque, kutenderera kumhanya, uye tembiricha), iyo yekumhanya-munguva uye mutoro curve inogona kuvandudzwa kuti iwedzere kushanda nesimba.
VI. Mamiriro eIndasitiri uye Kutevedzera
- Teerera kune zviyero zvakaita seISO 6014 (Nzira dzekuyedza dzePasi-inofambisa Machina) uye GB/T 25695 (Technical Conditions for Track-type Construction Machinery Chassis);
- Yemidziyo yekutumira kunze, tevedzera zvinodiwa nedunhu setifiketi seEC uye ANSI.
Summary
Iwo mana-roller anomhanya bvunzo yeanokambaira undercarriage chassis inofanirwa kunyatsobatanidzwa nemamiriro chaiwo ekushanda emuchina wekuvaka. Kuburikidza nesainzi mutoro simulation, kunyatso tarisisa data uye kuomarara kutadza kuongororwa, kuvimbika uye hupenyu hurefu hwesevhisi yechina-mavhiri system munzvimbo dzakaoma zvinogona kuvimbiswa. Panguva imwecheteyo, mhinduro dzebvunzo dzinofanirwa kupa hwaro hwakananga hwekuvandudza dhizaini (sekusarudzwa kwezvinhu uye kuisa chisimbiso chimiro), nekudaro kudzikisa kutadza kwekutengesa-shure kwekutengesa uye kuwedzera kukwikwidza kwechigadzirwa.
