Rulmenti cu role cilindrice
Rulmentii radial-axiali cu bile pe un rand, de obicei utilizati pentru utilaje de mare viteza, in functie de utilizarea lor, se pot construi in diferite variante si cu diferite unghiuri de contact. Unghiul de contact al seriilor 72B si 73B au unghiul de contact de 40 de grade. Rulmentii utilizati la brose au colivii din rasini feroase sau din alama si de obicei sunt cei din seriile 718, 719, 70 si 72 ce se executa in clasele de toleranta P5, P4 si P2 cu diametru interior de 100mm si unghi de contact de 15 grade C, respectiv 25 grade A.
Detalii rulmenti radial-axiali cu bile pe un rand
Toleranta: Se executa in clasa de toleranta normala si la cerere in clasa de toleranta P5 rulmentii radial-axiali cu bile pe un rand din seriile 73B cu unghi de contact de 40 grade . Cei din seriile 70C, 72C,70A,72A cu unghi de contact de 15grade C, respectiv 25grade A se executa in clasa de toleranta SP, P4, UP, P2. Livrarea se face in seturi de 2, 3 sau 4 la jumatatea valorii de toleranta inscriptionata pe ambalaj.
Joc radial/axial: Jocul axial la livrare sau pretensionarea se obtin la montarea pe utilaj cu exceptia celor in aranjament DB si DF ce se executa cu o pretensionare initiala (usoara, medie, mare). Valorile jocului si ale pretensionarii se pot afla numai in momentul in care arborele se afla in campul a de toleranta J5 iar alezajul carcasei in J6.
Colivii: Se executa cu colivii ambutisate din tabla rulmentii din seriile 72B si 73B se executa iar cei din seriile 70C,72C,70A, 72A cu colivii din stratitex sau, la cerere din alama.
Incarcare: Pentru a calcula sarcinile maxime admise consultati catalogul in cazul fiecarei serii de rulmenti radial-axiali cu bile pe un rand.
Inclinare: Conditiile privind pozitia inclinata admisa a inelului exterior sunt la fel cu cele ale rulmentilor radiali cu bile pe un rand. La cei radial-axiali cu bile pe un rand in aranjament DB pozitia inclinata a inelului exterior fata de cel interior este preluata numai in mod fortat de catre bile si cai de rulare scazand astfel durabilitatea rulmentilor.
Altele: In executie universala sunt destinati aranjamentului DB, DF, DT. Acestia au toleranta mai redusa si pot fi imperecheati in variantele UA, UO, UL. Abateri de la diametrul alezajului permit rulmentii din clasele de toleranta P4, UP, P2.
