Hi i have a doubts as im monitoring this gear box i have the follwing data 400/800 HP 450/900 RPM INPUT 20/40 RPM OUTPUT 22:1 REDUCTION is there a way of finding the teeth number on each gear? i have data results (FFT)...

thankyou very much (Reb,Hatch,sack ..all)for your answers it was very helpfull i have another doubts as im monitoring this gear box i have the follwing data 400/800 HP 450/900 RPM INPUT 20/40 RPM OUTPUT 22:1 REDUCTION...

Hi all can you please tell me if i can get the diameter of a gear by knowing the number of teeth. and is there a site where can i get more info a bout gears Thankyou.

HI 1)cheking the the rest of the information today I got this, the first side band at the input shaft a)2636 Hz,2880Hz both at the same amplitude b)5390Hz, 5645Hz again both at the same amp and the third SB c)8347Hz,8095hz d)yes the driver machine is a turbine 2) yes the AMPLITUDE of the...

hi i would like to get your input on this i'm monitoring a gearbox with an input shaft of 7525 RPM output shaft 1800 rpm with a 4,181 gear ratio 22/92 teeth last time i have run analysis on this gear box i got some reading on the FFT for input shaft of 251 Hz,502 Hz,751Hz, i got almost the same...

Hi try this link it’s an easy on line tutorial in a general way to vibration http://web.ukonline.co.uk/d.stevens2/vibanalysis/index.html i hop this will help bk33

Dear mzl Have a look at this site, there are some good information and basics about vibration . good luck http://web.ukonline.co.uk/d.stevens2/vibanalysis/index.html BK33

juan when you say you want to monitor the behaviour of the wheel , i think you should take into consideration the vabrational behaviour of the traction motors and gearboxes Then i would monitor the Low Speed Gear, Front and Rear axle high Speed Gear, Front and Rear axle,traction Motor, Front...

Dear kashyap see if those websites would be of any help to you if you need more info let me know. http://web.ukonline.co.uk/d.stevens2/vibanalysis/index.html http://www.davidson.com.au/

try this site www.swantech.com

Thanks Hatch it was very helpfull the site you indicated . one of the problem i'm faced with is i do not have a good bearing database: SKF,NSK...

Hi all can somone please tell if there is a bearing database, that can downloaded. Thankyou

i would suggest a product, that has being used in various areas of the market and i found it much more esier to work with, go to . www.swantech.com

Hi Hatch.Noise zooming in on the fft the only sideband freq nearrer to the (1458+17 1458-17) i found 1485hz and 1440hz but in very low Magnitude. the 17Hz Harmonics i still puzzling me even tough it seems to be related to the output shaft vibration seems to be higher in the input shaft...

hi Hatch,Noise thanks for your shared information i spent my day yesterday getting the data of that unit .. the gear ratio of is 7.12 to 1 25teeth on the gear on the input shaft the input speed is 3500 cpm/rpm / 58Hz 178 teeth on the gear on the output shaft, having the GMF about 1456 Hz...
