How much do you think this ring gear weighs?

admin

I was asked about removing this ring gear from the building it is in, just trying to make a guesstimate on how much it weighs.The picture is not the best because it is a picture of a picture but you can get the idea from it. I haven't seen it yet but the info given to me was as follows.The gear stands 101 1/2" tall, 5 3/4" wide and from the edge of the teeth to the inside edge is 3 3/4 thick".  Any guesses?

Reply:Assuming that the cut gears have a 'real' thickness of 3.25" vs the measured 3.75", Use a diameter of 101" (x 3.14) to get a length (circumference) of ~317",   then 317 x 5.75" x 3.25 = 5924 cu. in.    and 5924 cu. in.  x  0.28 lb/ cu. in. = 1659 pounds,this assuming further that it's steel as it appears to be..Last edited by Oldiron2; 01-28-2011 at 11:03 PM.Reason: added comma......

Reply:1940 lbs. minu the cutouts for teeth."The things that will destroy America are prosperity at any price, peace at any price, safety first instead of duty first, the love of soft living and the get rich quick theory of life." -Theodore Roosevelt
Reply:1876 lbs minus the cutouts for the teeth.
Reply:I calculated the area of the entire circle (3.1415 X 50.75 X 50.75 = 8091.4)I then calculated the area of the center of the ring (3.1415 X 47 x 47 = 6939.8)I then subtracted the center of the ring from the entire circle from (8091.4 – 6939.8 = 1151.6)I then multiplied the area of the ring by the thickness (1151.6 X 5.75 = 6621.7 cu in) I then multiplied cu in of the ring (6621.7 X .29 = 1920.3 lbs)I was not able to calculate the weight of the voids between the teeth because you did not supply tooth geometry this needs to be subtracted from the above weight to get the correct weight

Reply:d=101" so c= 26.44'5.75" x 3.75"= .479' x.3125'=.148sf ignoring tooth profile x26.4lf=3.95cf assuming steel @ 490#/cf=1936 pounds.
Reply:Just a thought for you fellows who need to figure the tooth cutouts, try figuring a ring with a ID from the root of the teeth and the current OD and half that amount which would account for the cutouts and add that to the remainer of the ring. You would need to know the depth of the teeth to do this. Have fun.

Reply:Originally Posted by Oldiron2I finally can't resisting asking you what the situation is with this gear. Was it in for repair, for inspection, what was just done to it by that device shown, was it removed from some equipment there, what kind of machinery does it go with, how did you get involved in moving it.......I assume they don't intend for it to be cut up and removed, as I believe someone above suggested.

Reply:windmills would use an internal ring gear to slew the nacelle into the wind.   basically rotate the dog house at the top of the pole to face into the wind.   Like the slewing gear on an excavator or a crane but i doubt this is from one of those.it looks like they were trying to magnaflux it with that setup.Vantage 500's LN-25's, VI-400's, cobramatics, Miller migs, synch 350 LX, Powcon inverters, XMT's, 250 Ton Acurrpress 12' brake, 1/4" 10' Atlantic shear,Koikie plasma table W/ esab plasmas. marvel & hyd-mech saws, pirrana & metal muncher punches.
