Повреда на зъбна предавка на ротационна пещ

Този практически случай описва откриването на повреда на зъбно колело на изходящия вал, открита по време на изпитание за производителност, включващо увеличаване на скоростта.

Мелницата за целулоза Södra Cell Värö в южна Швеция използва онлайн системата Intellinova с HD технология за измерване, за да наблюдава задвижванията на своята ротационна пещ. Заедно с изпитанието за производителност, при който скоростта на въртене е леко увеличена, се наблюдават нарастващи тенденции на ударни импулси. Това, което първоначално се смяташе за проблем с вътрешните зъбни колела или лагери, се оказа пукнатина на зъбно колело на изходящия вал.
