Namhlanje, ukuxilongwa kwempazamo yeebheringi eziqengqelekayo kwiibhokisi zegiya kwaziswa ngokweenkcukacha.Imeko esebenzayo yebhokisi yegiya ihlala ichaphazela ngokuthe ngqo ukuba isixhobo sokuhambisa sinokusebenza ngokwesiqhelo.Phakathi kokungaphumeleli kwecandelo kwiibhokisi zegiya, iigiya kunye neebheringi zineyona nxalenye inkulu yokungaphumeleli, ukufikelela kwi-60% kunye ne-19% ngokulandelanayo.

Imeko esebenzayo yebhokisi yegiya ihlala ichaphazela ngokuthe ngqo ukuba isixhobo sokuhambisa sinokusebenza ngokwesiqhelo.Iibhokisi zegiya zihlala zibandakanya iigiya, iibheringi eziqengqelekayo, iishafts kunye nezinye izinto.Ngokwezibalo, phakathi kweemeko zokungaphumeleli kweebhokisi zegiya, iigiya kunye neebheringi zibangela ukusilela okukhulu, okuyi-60% kunye ne-19%, ngokulandelanayo.Ke ngoko, ukusilela kwebhokisi yegiya Uphando lokuxilonga lugxile kwiindlela zokungaphumeleli kunye neendlela zokuxilonga iigiya kunye neebheringi.

Njengokuxilongwa kwempazamo yokuqengqeleka kweebheringi kwiibhokisi zegiya, inezakhono ezithile kunye nezinto ezithile.Ngokwamava entsimi, ukufunyaniswa kweempazamo eziqengqelekayo kwiibhokisi zegiya kuqondwa kwindlela yokuxilongwa kwetekhnoloji yevibration.

Qonda ubume bangaphakathi bebhokisi yegiya kunye neempawu zokungaphumeleli kokuthwala

Kuya kufuneka wazi ubume obusisiseko bebhokisi yegiya, efana nokuba yeyiphi indlela igiya ekuyo, zingaphi iishafu zothumelo ezikhoyo, zeziphi iibheringi ezikwishaft nganye, kwaye zeziphi iintlobo zeebheringi.Ukwazi ukuba yiyiphi i-shafts kunye nezixhobo ezihamba ngesantya esiphezulu kunye ne-heavy-duty-duty kunokunceda ukumisela ukulungelelaniswa kwamanqaku okulinganisa;ukwazi isantya semoto, inani lamazinyo kunye nomlinganiselo wothumelo lwegiya ngalinye lothumelo lunokunceda ukumisela ukuphindaphindwa kweshaft nganye yothumelo.

Ukongezelela, iimpawu zokusilela kufuneka zicace.Phantsi kweemeko eziqhelekileyo, i-frequency meshing yegiya kukuphinda-phinda okudityanisiweyo kwenani leegiya kunye nomjikelezo ojikelezayo, kodwa uphawu lokuphindaphindeka kokungaphumeleli kokuthwala ayisiyiyo ukuphindaphinda okudibeneyo kokujikeleza okujikelezayo.Ukuqonda ubume bangaphakathi bebhokisi yegiya kunye neempawu zokungaphumeleli kokuthwala yinto yokuqala efunekayo kuhlalutyo oluchanekileyo lokuqengqeleka kokusilela kwiibhokisi zegiya.

Zama ukulinganisa intshukumo ukusuka kumacala amathathu: ngokuthe tye, ngokuthe nkqo kunye ne-axial

Ukukhethwa kwamanqaku okulinganisa kufuneka kuthathele ingqalelo i-axial, i-horizontal kunye nezalathiso ezithe nkqo, kunye nokulinganisa ukungcangcazela kumacala amathathu akunakwenziwa kuzo zonke iindawo.Kwibhokisi yegiya ene-heat sink, indawo yokulinganisa i-shaft yokufaka ayifanelekanga ukuyibona.Nokuba ezinye iibheringi zibekwe embindini we-shaft, ukungcangcazela kwezinye iindawo akulunganga ukulinganisa.Ngeli xesha, ulwalathiso lwendawo yokulinganisa lunokumiselwa ngokukhethiweyo.Nangona kunjalo, kwiindawo ezibalulekileyo, umlinganiselo wokungcangcazela kumacala amathathu uyenziwa ngokubanzi.Nika ingqalelo ekhethekileyo ukuba ungawuhoyi umlinganiselo we-axial vibration, kuba iimpazamo ezininzi kwibhokisi yegiya ziya kubangela utshintsho kumandla okungcangcazela kwe-axial kunye nokuphindaphinda.Ukongezelela, iiseti ezininzi zedatha ye-vibration kwindawo efanayo yokulinganisa inokubonelela ngedatha eyaneleyo yohlalutyo kunye nokuzimisela kwesantya se-shaft yokuhambisa, kunye nokufumana ireferensi engakumbi yokuxilongwa okuthe kratya apho ukungaphumeleli kokuthwala kubaluleke kakhulu.

Qwalasela zombini intshukumo ephezulu kunye nesezantsi

Isiginali ye-gearbox vibration iqulethe izinto ezinje ngokuphindaphindiweyo kwendalo, ukujikeleza rhoqo kweshaft yokuhambisa, i-gear meshing frequency, uphawu lokungaphumeleli kokuthwala, usapho lokuguqulwa kwamaza, njl.Xa ubeka iliso kwaye uxilonga olu hlobo lwe-broadband frequency component vibration, ngokuqhelekileyo kuyimfuneko ukuhlelwa ngokwebhendi yefrikhwensi, kwaye emva koko ukhethe uluhlu oluhambelanayo lomlinganiselo kunye nesivamvo ngokoluhlu lwamaza ohlukeneyo.Umzekelo, iisensonsi zokukhawulezisa ezisezantsi zihlala zisetyenziswa kwiibhendi eziphantsi, kwaye iisensonsi zokukhawulezisa ezisemgangathweni zingasetyenziswa kwifrikhwensi ephezulu kunye neebhendi eziphezulu.

Ukulinganisa ukungcangcazela kangangoko kunokwenzeka kwizindlu zokuthwala apho i-shaft nganye yokuqhuba ikhona

Kwizikhundla ezahlukeneyo kwizindlu zebhokisi yegiya, impendulo kwisivuseleli esifanayo yahlukile ngenxa yeendlela ezahlukeneyo zokuhambisa umqondiso.Izindlu ezithwele apho i-shaft yokuhambisa i-gearbox ikhoyo inovakalelo kwimpendulo ye-vibration ye-bearing.Indawo yokubeka iliso ibekwe apha ukuze ifumane ngcono umqondiso wokungcangcazela, kwaye iindawo eziphezulu kunye neziphakathi zezindlu zisondele kwindawo yokuhlangana yegiya, ekulungele ukubeka iliso kwezinye iintsilelo zegiya.

Gxininisa kuhlalutyo lwamaza e-sideband

Kwizixhobo ezinesantya esiphantsi kunye nokuqina okuphezulu, xa iibheringi ezikwibhokisi yegiya zinxitywe, i-vibration amplitude yeempawu zokusilela kweempawu zihlala zingafani naleyo, kodwa ngophuhliso lokungaphumeleli kokunxiba, i-harmonics i-frequency frequency of the bearing failure are harmonic.Iza kuvela ngamanani amakhulu, kwaye kuya kubakho inani elikhulu lamabhanti asecaleni ajikeleze la maza.Ukwenzeka kwezi meko kubonisa ukuba i-bearing ilahlekelwe kakhulu kwaye kufuneka itshintshwe ngexesha.

Xa uhlalutya idatha, qwalasela zombini iiplani ze-spectral kunye nexesha le-domain

Xa i-gearbox isilela, ngamanye amaxesha i-vibration amplitude yefault factor nganye ayitshintshi kakhulu kumzobo wespectrum.Akunakwenzeka ukugweba ubunzima besiphoso okanye ixabiso elichanekileyo lesantya se-intermediate drive shaft, kodwa sinokugqithiswa kwidayagram yesizinda sexesha.Ubuninzi bempembelelo yokuhlalutya ukuba impazamo ibonakala okanye isantya se-drive shaft sichanekile.Ke ngoko, ukumisela ngokuchanekileyo isantya sokujikeleza kweshaft nganye yothumelo okanye ukuphindaphindeka kwempembelelo yempazamo ethile, kuyafuneka ukuba ujonge zombini umzobo we-vibration spectrum kunye nomzobo wesizinda sexesha.Ngokukodwa, ukuzimisela kokuphindaphinda kwentsapho ye-frequency ye-harmonics engaqhelekanga ayinakwahlulwa kuhlalutyo oluncedisayo lomzobo wesizinda sexesha.

Kungcono ukulinganisa ukungcangcazela phantsi komthwalo ogcweleyo weegiya

Ukulinganisa ukungcangcazela kwebhokisi yegiya phantsi komthwalo ogcweleyo, onokuthi ubambe umqondiso wempazamo ngokucacileyo ngakumbi.Ngamanye amaxesha, kumthwalo ophantsi, ezinye iimpawu ezibonisa iimpazamo ziya koyiswa zezinye iimpawu kwibhokisi yegiya, okanye zimodareyithwe zezinye imiqondiso kwaye kunzima ukuzifumana.Ngokuqinisekileyo, xa i-fault fault inzima, kumthwalo ophantsi, isignali yephutha inokubanjwa ngokucacileyo nakwi-speed spectrum.
