Abstract

Sproket rantai rol pada sepeda motor merupakan komponen yang sangat penting, komponen ini berfungsi untuk mentransmisikan daya dari mesin penggerak ke roda belakang. Dalam pengoperasiannya komponen sproket selalu bergesekan dengan rantai dari sepeda motor, dari gesekan tersebut yang akan menyebabkan keausan dan berkurangnya umur pakai.  Jenis keausan yang terjadi pada komponen sproket yaitu keausan adhesi dan abrasi, sedangkan untuk umur pakai sendiri dari komponen sproket yang diteliti telah mengalami pemakaian selama 420 hari atau 30.738.960siklus. Untuk umur pakai sproket sampai kondisi harus diganti, pemakaian selama 4,1 tahun atau 105,742,022,4 siklus. Komponen sproket sendiri sebelumnya telah dilakukan proses pengerasan permukaan, dengan metoda induksi. Dari hasil pengujian kekerasan dapat dilihat penurunan harga kekerasan dari permukaan ke bagian dalam. Strktur mikro yang terbentuk pada daerah permukaan yang dikeraskan terbentuk fasa martensit dan ferrite, sedangkan untuk daerah yang potongan melintang memiliki martensit austenit, perit (hitam) dan pearlite. Komponen sproket termasuk ke dalam baja karbon medium, sesuai dengan AISI 1040.
