420 Vibration Characteristics of Spiral Bevel Gears : Rotational Vibration of Gears and Meshing Transmission Error

Abstract

Recently, spiral bevel gears have come to be used widely as transmission gears of cars. Running test of gears is a most effective method for measuring rotational vibration of gears. In this paper, we measured rotational acceleration of Oerlikon spiral bevel gears under various conditions, using acceleration sensor on the output drive gear and driven gear. In addition, the relationship for meshing transmission error in the low revolution was examined. As the result, drive gear and driven gear have done the relative motion, and the meshing transmission error it can calculate by measuring the rotational vibration of each gear,
