Title: Sprocket
IPC: F16H55/48
Filed: 1992-04-03
Abstract: PURPOSE:To reduce a weight and improve a thermal discharge characteristic by forming a sprocket of a polyamide resin which includes metal fiber by a specified amount. CONSTITUTION:Metal fiber such as brass fiber is blended in a polyamide 6 by 5 to 15wt.% for forming a cam sprocket 1. A cam shaft 2 is installed thereto by spline fitting.
