Inspection and repair on MAAG LGD-50 gearbox

The condition of the ball mill gearbox can be considered as good, no acute damage has been observed on the gears or in the bearings. On the electromotor indications for bearing damage have been observed. All additional checks were carried out successfully. Vibration measurement

No immediate signs of bearing damage have been observed. However without gear teeth numbers it is not possible to identify the origins of individual signals, making measurements less efficient. To make optimal use of vibration measurement technologies it is advised to obtain gear teeth numbers from the manufacturer.
