1.Kutsemuka uye Kutsemuka
Chitubu chemashizhaKutyoka kunowanzoitika mushizha guru kana zvidimbu zvemukati, zvichiratidza sepakatsemuka kana kutsemuka zvachose.
Zvikonzero Zvikuru:
-Kuremedza & Kuneta: Kurebesa mitoro inorema kana zvinodzokororwa zvinodarika muganho wekuneta kwechirimo, kunyanya mushizha guru.berezvizhinji zvemutoro.
-Material & Manufacturing Defects: Yakaderera chitubu simbi (semuenzaniso, haina kukwanaSUP9kana 50CrVA giredhi) kana kukanganisa kupisa kurapwa (semuenzaniso, kusakwana kudzima kana kupisa) kuderedza kuoma kwezvinhu.
-Kuisa / Kugadzirisa Kusina kunaka: Kuwedzeredza-kuomeswa kana kusunungukaU-mabhaudhikukonzera kusaenzana kwekushushikana kwekugovera, nepo kushaikwa kwekuzora pakati pemashizha kunowedzera kukweshera uye kushushikana kwekufunga.
2. Deformation uye Arcuate Loss
Zvitubu zvemashizha zvinogona kukotama, kumonyoroka, kana kurasikirwa nechimiro chazvo, zvichikanganisa kuoma kwekumiswa uye kugadzikana kwemotokari.
Zvikonzero Zvikuru:
-Abnormal Loading: Kugara uchivhiya munzvimbo dzakaipa kana kusamira zvakanaka kwekutakura zvinhu zvinokonzeresa kuwandisa kwenzvimbo.
-Thermal Kukuvadza: Kuswedera kune exhaust masisitimu kana yakakwirira-tembiricha zvikamu zvinonetesa elasticity yesimbi, zvichitungamira kune epurasitiki deformation.
-Kuchembera: Kushandiswa kwenguva refu kunoderedza simbi elastic modulus, zvichikonzera deformation zvachose.
3. Kusununguka uye Noise Yakashata
Metallic rattling kana kudzvova panguva yekutyaira, kazhinji nekuda kwekubatana kwakasununguka kana zvinhu zvakasakara.
Zvikonzero Zvikuru:
-Loose Fasteners:U-mabhaudhi,mabhaudhi epakati, kana kuti zvimedu zvechitubu zvinosunungura, zvichibvumira mashizha kana maekisero akabatana kuti afambe nekukwesha.
-Makwenzi Akasakara: Yakashatiswa rabha kana polyurethane bushings mumaketani kana ziso rinogadzira kucheneswa kwakanyanya, zvichitungamira kune ruzha-runokonzeresa.
-Kusakwana kweLubrication: Girisi yakaomeswa kana kushaikwa pakati pemashizha inowedzera kukweshana, zvichikonzera kurira uye kukurumidza kupfeka.
4. Pfeka uye Corrosion
Mikova inooneka, ngura, kana kudzikisira ukobvu pamashizha.
Zvikonzero Zvikuru:
-Environmental Factors: Kusangana nehunyoro, munyu (semuenzaniso, migwagwa yechando), kana makemikari anoparadza anokonzera ngura; madhaka nemarara ari mumikaha yemashizha anowedzera kupfeka zvinokuvadza.
-Abnormal Inter-Leaf Sliding: Kushaikwa kwekuzora kana mashizha akaremara zvinotungamira mukutsvedza zvisina kuenzana, kugadzira mikororo kana nzvimbo dzakati sandara pamashizha.
5. Elasticity Degradation
Kudzikira kutakura mutoro, kunoratidzwa nekusajaira kukwira mota kureba (semuenzaniso, kuderera) pasihapana mutorokana mutoro wakakwana.
Zvikonzero Zvikuru:
-Kuneta Kwezvinhu: Kudzokororwa kwakakwira-frequency vibrations kana cyclic kurodha zvinokuvadza chimiro chekristaro chesimbi, ichidzikisa muganho wayo.
-Heat Treatment Defects: Kusakwana kuomesa kana kushatisa zvakanyanya kunoderedza chitubu modulus ye elasticity, kukanganisa kugona kwayo kudzokera kuchimiro chayo chepakutanga.
6. Kusarongeka kweGungano
Zvitubu zveshizha zvinosimuka kubva panzvimbo yazvo paekisero, zvichikonzera kusakara kwetai kana kutyaira kutsauka.
Zvikonzero Zvikuru:
-Kukanganisa Kuisa: Kusarongekabhaudhi repakatimaburi kana zvisizvo U-bhaudhi inoomesa mitsetse panguva yekutsiva inotungamira kune mashizha kusamira zvakanaka.
-Yakakuvadzwa Rutsigiro Zvikamu: Yakaremara axle chitubu zvigaro kana akatyoka shackle mabhuraketi anomanikidza chitubu kubva mukurongeka.
Mhedziso: Kukanganisa uye Kudzivirira
Chitubu chemashizhazvikanganiso mumarori anorema zvinonyanya kubva mukuremedza zvakanyanya, kukanganisa kwezvinhu, kuregeredzwa kwekuchengetedza, uye mamiriro ekunze. Kuongororwa nguva nenguva (semuenzaniso, macheki ekuona kutsemuka, kuyerwa kwearch urefu, kuongororwa kweruzha) uye gadziriso inogadzirisa (kuzora, kusimba kwekusimbisa, kudzivirira ngura) kwakakosha mukuderedza njodzi. Kune zvinorema-basa kunyorera, kukoshesa zvemhando yepamusoro, kuomerera kumiganho yekutakura, uye kugadzirisa nyaya nekukasira kunogona kuwedzera zvakanyanya hupenyu hwemashizha echirimo uye kuve nechokwadi chekuchengetedza kushanda.
