Analysis of damage origin of bevel gear wheels

Abstract

The safety and smooth operation of manufacturing facilities also depends on ensuring the failure-free operation of technical equipment. Power transmission failures in particular are usually the cause of shutdown of the entire manufacturing facility. The characterization of gear failures ac-cording to their origin plays an important role in determining safe operating conditions. The presented paper is dedicated to the problem of damage of specific gears, defining the extent of damage, determining the possible causes of damage. The problem is solved for a single-stage helical bevel gearbox with, which is a part of the mechanism of a small hydroelectric power plant. The aim is to determine the conditions for proper operation, based on the evaluation of the extent of damage to this gearbox, so that the gearbox is no longer damaged to such a large extent.
