Gibrid podshipniklar
Kirish
Gibrid podshipniklarda rulmanli po'latdan yasalgan halqalar va rulmanli silikon nitrididan (Si3N4) yasalgan prokat elementlari mavjud bo'lib, ular podshipniklarni elektr izolyatsiyasini ta'minlaydi.
Silikon nitridli prokat elementlari qiyin ish sharoitlarida ham yaxshilangan rulman ish faoliyatini taklif qilish orqali rulmanning xizmat qilish muddatini uzaytirishi mumkin.
Rulmanlarda kremniy nitridining eng to'g'ridan-to'g'ri qo'llanilishi gibrid rulmanlar qilishdir.To'p yoki rulo silikon nitridli materialdir va metalldan yasalgan ichki va tashqi halqali rulman gibrid rulman deb ataladi.Gibrid rulmanning to'pi yoki boshqa roligi sifatida, silikon nitridini qo'llash bozori o'sib bormoqda.Quyidagi jadvalda rulman materiali sifatida silikon nitridli keramikaning afzalliklari va o'ziga xos qo'llanilishi ko'rsatilgan.Silikon nitridi kiyganda, u podshipnik po'latiga o'xshash xususiyatlarni ko'rsatadi, ya'ni u to'liq singandan ko'ra chuqurlashadigan nuqtalarni hosil qiladi va ishqalanish qarshiligi kuchayadi va shovqin kuchayadi, lekin podshipnik hali ham ishlashi mumkin. Yomon moylanganda. yoki hatto quruq operatsiya, materialga to'satdan zarar etkazilgan taqdirda, u favqulodda holatda ham ishlashi va yaxshi ishlashi mumkin.
Afzallik
● Elektr tokining shikastlanishidan himoya qilish
Gibrid podshipniklar o'tkazuvchan emas va shuning uchun elektr toki mavjud bo'lgan AC va DC motorlar va generatorlar kabi ilovalar uchun javob beradi.
● Yuqori tezlik qobiliyati
Silikon nitridli prokat elementining zichligi rulmanli po'latdan yasalgan bir xil o'lchamdagi prokat elementidan 60% past.Kamroq og'irlik va inertiya yuqori tezlik qobiliyatiga va tez boshlash va to'xtash vaqtida yuqori harakatga aylanadi.
● Uzoq xizmat muddati
Gibrid podshipniklarda, ayniqsa yuqori tezlikda hosil bo'ladigan past ishqalanish issiqligi, podshipniklarning xizmat qilish muddatini uzaytiradi va qayta moylash oraliqlarini uzaytiradi.
● Yuqori aşınma qarshilik
Silikon nitridli prokat elementlari yuqori qattiqlik darajasiga ega bo'lib, gibrid podshipniklarni qiyin sharoitlarda va ifloslangan muhitda moslashtiradi.
● Rulmanning yuqori qattiqligi
Yuqori elastiklik moduli bilan gibrid podshipniklar rulmanning qattiqligini oshiradi.
● Kirlanish xavfi kamayadi
Yuqori tezlik va tez sur'atlar kabi noto'g'ri moylash sharoitida ham yoki gidrodinamik plyonka etarli bo'lmagan hollarda ham, kremniy nitridi va po'lat yuzalar o'rtasida bo'yash xavfi kamayadi.
● Soxta brinellash xavfi kamayadi
Vibratsiyaga duchor bo'lganda, gibrid podshipniklar kremniy nitridi va po'lat yuzalar o'rtasida noto'g'ri brinellanishga (yo'llarda sayoz chuqurliklarning shakllanishi) sezilarli darajada kam sezgir.
● Harorat gradientlariga nisbatan kam sezgirlik
Silikon nitridli prokat elementlari pastroq termal kengayish koeffitsientiga ega, ya'ni ular rulman ichidagi harorat gradientlariga nisbatan barqarorroq va oldindan yuklash / tozalashni aniqroq boshqarishni ta'minlaydi.
Ilova
Mexanik sanoatda silikon nitridli keramika turbinali pichoqlar, mexanik muhr uzuklari, yuqori haroratli podshipniklar, yuqori tezlikda kesish asboblari, doimiy qoliplar va boshqalar sifatida ishlatilishi mumkin. Ushbu qurilmalarning ishonchliligi va xizmat muddati metallarning korroziyasi tufayli katta ta'sir ko'rsatadi. .Biroq, silikon nitridli keramik materiallar mukammal aşınma qarshilik, korroziyaga chidamlilik va yuqori haroratli termal zarba qarshiligiga ega bo'lib, ular metall materiallar o'rniga mashinasozlik sanoatida qo'llanilishi mumkin.
