Pambuka
Bantalan hibrida duwe dering sing digawe saka baja bantalan lan unsur rolling sing digawe saka bantalan silikon nitrida (Si3N4), sing nggawe bantalan isolasi listrik.
Unsur rolling silikon nitrida bisa ngluwihi umur layanan bantalan kanthi menehi kinerja bantalan sing luwih apik, sanajan ing kahanan operasi sing angel.
Aplikasi paling langsung saka silikon nitrida ing bantalan yaiku nggawe bantalan hibrida.Bal utawa roller minangka bahan silikon nitrida, lan bantalan kanthi cincin njero lan njaba sing digawe saka logam diarani bantalan hibrida.Minangka bal utawa roller bantalan hibrida liyane, pasar aplikasi silikon nitrida saya akeh.Tabel ing ngisor iki nampilake kaluwihan lan aplikasi khusus keramik silikon nitrida minangka bahan bantalan.Nalika silikon nitride wis rusak, iku nuduhake ciri sing padha karo baja bantalan, yaiku, spalling kanggo mbentuk titik pitting, tinimbang rusak rampung, lan resistance gesekan mundhak lan swara mundhak, nanging bantalan isih bisa mlaku. utawa malah operasi garing, ing cilik saka karusakan dadakan kanggo materi, iku uga bisa operate lan nindakake uga ing negara darurat.
Kaluwihan
● Proteksi saka karusakan arus listrik
Bantalan hibrida ora konduktif lan mulane cocog kanggo aplikasi kayata motor lan generator AC lan DC, ing ngendi ana arus listrik.
● Kapabilitas kacepetan sing luwih dhuwur
Kapadhetan unsur rolling silikon nitrida 60% luwih murah tinimbang unsur rolling ukuran sing padha digawe saka baja bantalan.Bobot lan inersia sing luwih murah nerjemahake kemampuan kacepetan sing luwih dhuwur lan prilaku sing unggul sajrone wiwitan lan mandheg kanthi cepet.
● urip dawa layanan
Panas gesekan ngisor sing digawe ing bantalan hibrida, utamane ing kecepatan dhuwur, nyumbang kanggo umur layanan bantalan lan interval pelumasan maneh.
● dhuwur nyandhang-resistance
Unsur rolling silikon nitrida duwe tingkat kekerasan sing luwih dhuwur, nggawe bantalan hibrida cocog ing kahanan sing angel lan lingkungan sing kontaminasi.
● Kaku bantalan dhuwur
Kanthi modulus elastisitas sing dhuwur, bantalan hibrida nyedhiyakake kaku bantalan.
● Ngurangi risiko smearing
Malah ing kahanan pelumasan sing ora nyukupi, kayata kacepetan dhuwur lan akselerasi cepet, utawa ing ngendi ana film hidrodinamik sing ora cukup, risiko smearing dikurangi ing antarane permukaan silikon nitrida lan baja.
● Suda risiko brinelling palsu
Nalika kena geter, bantalan hibrida kurang rentan marang brinelling palsu (bentuke depresi cethek ing jalur balap) ing antarane permukaan silikon nitrida lan baja.
● Kurang sensitivitas kanggo gradien suhu
Unsur rolling silikon nitrida duwe koefisien ekspansi termal sing luwih murah, sing tegese luwih stabil tinimbang kecerunan suhu ing bantalan lan nyedhiyakake kontrol preload / clearance sing luwih akurat.
Aplikasi
Ing industri mekanik, keramik nitrida silikon bisa digunakake minangka bilah turbin, dering segel mekanik, bantalan suhu dhuwur, alat pemotong kacepetan dhuwur, cetakan permanen, lan liya-liyane. Keandalan lan umur layanan piranti kasebut kena pengaruh banget amarga korosi logam. .Nanging, bahan keramik silikon nitrida duwe resistensi nyandhang sing apik, tahan karat lan tahan kejut termal suhu dhuwur, sing bisa digunakake ing industri mesin tinimbang bahan logam.
