BELT CONVEYOR DRIVE GEARBOX PROBLEM CAUSED BY UNPAIRED GEARS- A CASE STUDY

Abstract: Belt conveyors for all kinds of materials are very important piece of equipment in mining and excavation industries. This paper is presenting a case study of belt conveyor driving unit vibration analysis. The analyzed belt conveyor is operating in cooper production plant and it is conveying cooper ore from mining site to process plant. In order to detect the possible defects on belt conveyor drive units, vibration measurements are conducted on all four drive units. Measurement points are set on bearing housings of electric motor and gearbox as defined by ISO 10816-1. Key words : gearbox vibration analysis, gear tooth wear, unpaired gears, shaft misalignment
