So it is a large synchronous motor coupled to a stub shaft, coupled to the pinon and it meshes with the bullgear that is on the outer circumference of the mill.I had a cage failure on one of the pinion bearing 2 years ago, at that time we replaced both bearings.
The bearings, the bearing lubrication system and the drive are also subjected to wear.Before beginning of the repair and shutdown of the mill the vibration is measured.Once the mill is shut down and the motor is de-energized, condition of all assemblies is checked, and the repair list is adjusted.
The cause of vibration of ball bearing shell of ball mill.Vibration at the ball bearing housing of the ball mill is a device failure that affects the normal operation of the ball mill.There are many reasons for causing low-frequency vibrations, and the vibrations and hazards caused by their respective causes are also different.
The greater the energy of vibration, the more severe the damage.The period of time and the magnitude of the bearing internal clearance also influence developments, but the frequency of the vibrations does not appear to have any significant effect.Roller bearings have proved to be more susceptible to this type of damage than ball bearings.
The HD ENV Filter 3 trend on the DE bearing follows a pattern similar to the SPM HD trend on the NDE bearing, and also has a spectrum showing BPFO match.Due to the close distance between the two bearings, the vibration sensor mounted on the DE bearing picks up the signal from the NDE bearing.The vibration readings do not show any sign of damage.
The vibration is high in all planes on both sides of the Mill or both pinion drives.The measurements were similar in velocity on the motor , gearbox and both pinion bearings.The recommendations for repairs was close to exactly the same for both drives.Gear mesh frequency is present at 1x to 3x and similar amplitudes on both sides.
This case involves a motor that has just been serviced.During the last six months, the motor showed elevato.Overall vibration catches bearing damage very late, when there may be 0.1% of the bearing lifetime left.
This case study deals with the successful detection of outer race damage on a ball mill pinion bearing.On the non-drive end bearing, the Intellinova online system initially indicated shock pulse levels that varied between green and yellow condition evaluation.This fluctuation was attributed to the operating conditions, with varying loads on .
Using vibration monitoring are the motor and gearbox assemblies.For a typical crusher motor, accelerometers are mounted radially on the Drive End (DE) and Non-Drive End (NDE), in order to monitor the motor bearing condition (g).‘Accelerometers used to measure vibration levels are usually easy to install and use.
