Coal Mill Ring Gear Pinion Vibration

How to install and align the girth gear and pinion prmdrive

Jan 14, 2020 The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.

Detailed Vibration Analysis of Pinion Gear with Time

operating load levels. The gear under study was the spiral bevel pinion with 19 teeth (fig. 3a). Nine notches were fabricated in the fillets on various teeth of the pinion. The notch sizes varied from 0.5 to 0.1" in length, and 0.015 to 0.045" in depth. The pinion was run 4.9 million cycles at 6060 rpm

Vibration monitoring for planetary gearbox in vertical

Vibration monitoring is one of the most important methods to detect and diagnose faults in gearboxes. Planetary gearbox in vertical axis coal mill experienced high impact load and severe working condition that increase wear and shorten usage life.

Ball Mill Pinion Vibration Analysis & Machinery

I have an issue with a gear drive on a ball mill. 2XGM is rising and i have sidebands at 107cpm and I don't know why they are at 107 (not relevant to any turning speeds ect.) I checked the root clearance a week ago and the inboard is about a .066 smaller than the outboard. The pinion is 24" long and has 24 teeth. It is obvious i have misalignment.And there is obvious spalling on the gear faces

High vibrations on a ball mill AMP Maintenance Forums

Jan 21, 2011 Compared with the previous gears on this mill, new gears have a larger modulus and different number of the teeth but with the similar gearmesh now 61.8Hz instead of 57Hz before. The old gears which were worn had smaller vibration values around 12 mm/s while now we have, with the new gears, around 28 mm/s with gearmesh frequencies and their

Vibration monitoring for planetary gearbox in vertical

This presentation will describe our strategy to improve vibration monitoring for planetary gearbox in vertical axis coal mill using spectrum analysis. Vibration analysis for planetary gearbox is more complicated than fixed shaft gearbox because planet gears mesh simultaneously with both the sun gear and the ring gear.

Root cause analysis of bowl-mill pinion shaft failures

Apr 01, 2013 This is mainly responsible for the subsequent movement of the bull ring segments through smaller gears mounted below it. The movement of bull ring segment, therefore, enables the movement of the 3 conical bowl mill rolls oriented at 120° to each other. The coal gets crushed between the rolls and the bull ring segment.
