High-power gear drives :
Running-in lubricants
The running-in phase is very important and determines the life span of the drive.
Indeed, damages can appear very quickly after the running-in. Even with very good mechanical settings, surface states are not perfect and the initial contact may represent only 50 to 60% due to machining or geometry imperfections.
In order to respect the mechanical strains for which the girth gear was calculated, it is very important to use a running-in lubricant (slow lapping without abrasive particles) with aim to improve the state of working flanks . This is achieved by distributing over a larger surface the transmission and the effective power.
The running-in procedure is different depending on the machine driven by the gear (mills in cement plants or coal power stations, kilns…).Therefore, it is necessary to respect the manufacturer’s instructions concerning the possible loading steps.
