Četru rindu konusveida rullīšu gultņi
Ievads
Četru rindu konusveida rullīšu gultņi var izturēt kombinētas (radiālās un aksiālās) slodzes zemā vai mērenā ātrumā.Tos izmanto gandrīz tikai velmētavās, piemēram, velmētavās.
Četras konusveida rullīšu gultņu rindas ir veiksmīgi izmantotas velmētavu gultņu konfigurācijā visā pasaulē ar zemu vai vidēju ātrumu.Pateicoties tā konstrukcijai, gultnis var izturēt radiālās slodzes papildus aksiālajām slodzēm, kas pastāv šādos lietojumos, un parasti gultņu konfigurācijā nav nepieciešami papildu vilces gultņi.Tas nozīmē, ka ruļļa stienis var būt salīdzinoši īss, un korpusiem abās ruļļa pusēs var būt vienāda konstrukcija.
Četru rindu konusveida rullīšu gultņi ir visbiežāk izmantotie rullīšu diametra gultņi.Šai konstrukcijai ir liela nestspēja, un tā var vienlaikus izturēt kombinētas radiālās un aksiālās slodzes, kuru pamatā ir radiālās slodzes.Tā radiālā slodze ir aptuveni 2,5 līdz 3,5 reizes lielāka nekā vienas rindas gultņiem, un tas var izturēt lielas radiālās slodzes un aksiālās slodzes.
Funkcijas un priekšrocības
● Vienkāršota uzstādīšana, jo ir mazāk komponentu
● Uzlabots četrrindu veltņu slodzes sadalījums, kā rezultātā samazinās nodilums un ilgāks kalpošanas laiks
● Aksiālā pozicionēšana uz ruļļa kakliņa ir vienkāršota, jo ir samazināta iekšējā gredzena platuma pielaide.
● Izmēri ir tādi paši kā parastajiem četrrindu konusveida rullīšu gultņiem ar starpgredzeniem
Pieteikums
Četru rindu konusveida rullīšu gultņi tiek izmantoti smagajās mašīnās, piemēram, lielās aukstās un karstās dzirnavās plastmasas mašīnu rūpniecībā.
