Solu\u021bii de transmisie cu cuplu ridicat pentru frontiera energiei regenerabile din Marea Britanie<\/h3>\n

Regatul Unit este un gigant global \u00een domeniul energiei eoliene, \u00een special \u00een medii dure, cu salinitate ridicat\u0103, precum Marea Nordului \u0219i Marea Irlandei. Pentru inginerii care administreaz\u0103 parcuri eoliene offshore mari, precum Dogg Beach sau Hornsey, sistemul de ac\u021bionare este inima turbinei. UK pto-drive-shafts.com Ltd., situat\u0103 \u00een inima East Anglia (Berry St Edmunds, Suffolk), \u00een\u021belege c\u0103 un arbore de transmisie industrial este mai mult dec\u00e2t o simpl\u0103 \u021beav\u0103 rotativ\u0103; este o punte proiectat\u0103 meticulos, care trebuie s\u0103 reziste p\u00e2n\u0103 la 25 de ani de sarcini ciclice continue, coroziune prin pulverizare cu sare \u0219i vibra\u021bii torsionale extreme.<\/p>\n

Realitatea inginereasc\u0103: Navigarea prin sistemul de propulsie al nacelei<\/h3>\n

\u00cen spa\u021biul limitat, cu o raz\u0103 de 100 de metri deasupra m\u0103rii turbulente, \u00een interiorul nacelei turbinei, sistemul de transmisie transform\u0103 rota\u021bia la vitez\u0103 mic\u0103 \u0219i cuplu mare a palelor \u00een rota\u021bia la vitez\u0103 mare a generatorului. Aceast\u0103 conversie necesit\u0103 doi arbori de transmisie diferi\u021bi: un arbore principal de vitez\u0103 mic\u0103 \u0219i un arbore de vitez\u0103 mare (HSS).<\/p>\n

1. Arborele principal (tura\u021bie redus\u0103 \/ cuplu ridicat)<\/h4>\n

Arborele principal este principala component\u0103 portant\u0103. Acesta trebuie s\u0103 suporte greutatea butucului \u0219i a palelor - de obicei dep\u0103\u0219ind 100 de tone - rezist\u00e2nd \u00een acela\u0219i timp momentelor enorme de \u00eempingere \u0219i \u00eencovoiere generate de v\u00e2nturile puternice. \u00cen turbinele eoliene moderne din clasa megawa\u021bilor (6 MW p\u00e2n\u0103 la 15 MW), folosim o\u021bel aliat 42CrMo4 de \u00eenalt\u0103 calitate, care este supus unei c\u0103liri \u0219i reveniri profunde pentru a asigura rezisten\u021ba miezului \u0219i a preveni fisurarea la oboseal\u0103 pe parcursul a milioane de cicluri.<\/p>\n

2. Arborele de mare vitez\u0103 (HSS) \u0219i necesitatea izola\u021biei<\/h4>\n

Conect\u00e2nd ie\u0219irea cutiei de viteze la generator, HSS func\u021bioneaz\u0103 la tura\u021bii semnificativ mai mari. Principala provocare inginereasc\u0103 aici este coroziunea electric\u0103 (pitting). Generatoarele produc adesea \u201ecuren\u021bi parazi\u021bi pe lag\u0103re\u201d sau curen\u021bi pe arbore. Dac\u0103 ace\u0219ti curen\u021bi c\u0103l\u0103toresc printr-un cuplaj metalic \u00een cutia de viteze, distrug pelicula de ulei de pe lag\u0103re, duc\u00e2nd la defec\u021biuni catastrofale.<\/p>\n

\u201e\u00cen cei 14 ani de experien\u021b\u0103 \u00een service-ul turbinelor din largul coastelor Lowestoft \u0219i Great Yarmouth, cel mai frecvent factor de risc \u00abinvizibil\u00bb pe care l-am observat nu este uzura mecanic\u0103, ci eroziunea electric\u0103. \u00cen 2022, am inspectat un amplasament \u00een care cuplajele standard se defecteau la fiecare 18 luni. Prin integrarea arborilor no\u0219tri de transmisie izola\u021bi cu plastic armat cu fibr\u0103 de sticl\u0103 (GFRP), am asigurat o barier\u0103 dielectric\u0103 de 5 kV. Doi ani mai t\u00e2rziu, acele cutii de viteze func\u021bioneaz\u0103 la o tensiune de 100%, f\u0103r\u0103 coroziuni electrice \u00een lag\u0103re. Dac\u0103 nu izola\u021bi sistemul HSS, practic a\u0219tepta\u021bi ca un tr\u0103snet s\u0103 v\u0103 conecteze la mas\u0103 angrenajele.\u201d<\/i>\u00a0\u2014\u00a0Inginer mecanic senior, Marea Britanie pto-drive-shafts.com<\/i><\/p>\n<\/blockquote>\n
