    Nonidealities in very large spur gear train

    Thank you very much! I will certainly talk to the manufacturer to discuss if additional work on the gears is possible at this point. Best, A. Craig

    Nonidealities in very large spur gear train

    Hello, Thank you very much! That was a very clear and helpful description which helps me to understand what is going on in my system. I greatly appreciate you taking the time to explain! Best, A. Craig

    Nonidealities in very large spur gear train

    Hello, We actually are considering remaking the plates at this point, so I will certainly experiment with the spacing before finalizing the specifications. Thank you very much for your insight! The mounting distance was one of the few things that I hadn't been thinking could be wrong. Best...

    Nonidealities in very large spur gear train

    Hello, Wow, it is impressive that you are able to understand so much about the system from the wear pattern, especially considering a poor photograph! Would additional photos be helpful, and if so, what should I be trying to show? Thank you again so much for your help! Best regards, A. Craig

    Nonidealities in very large spur gear train

    Hello, Yes, I know I am being frustratingly vague; this is part of a research project and at present I don't think it is possible to provide a detailed schematic or an exact description of purpose. I am terribly sorry about this; I do not mean to waste people's time by being unhelpful. I am...

    Nonidealities in very large spur gear train

    Hello, I am terribly sorry the photo wasn't helpful! I took it with my camera, but I was using macro focus so that the between -gear surface details would be clear. I take it a large, overall view with less detail is more helpful in this case? I will take and post better photos shortly, but...

    Nonidealities in very large spur gear train

    Hello, Thank you very much for your help! I am using a flexible coupling which allows for parallel and angular misalignment but is axially stiff, so it is still allowing a thrust to transmit. Here is the manufacturing data on the gears: Pitch 32DP Pressure angle 20 No. of teeth 32 Major...

    Nonidealities in very large spur gear train

    Hello, The plates were not jig-bored, but I thought the CNC machining used was precise enough for the purpose. It seems that I might need to remake the plates, but before that I will certainly try adding spacers to see if that helps. The gears are not fully in series, but almost, so yes...

    Nonidealities in very large spur gear train

    Hello, Each gear is fitted with a ball bearing at the top and bottom of each shaft and each bearing is fit within a hole in the plate. That being said, the bearings are only 1/8" thick, so the contact area of support isn't very high. I understand that stainless-stainless is not the best idea...

    Nonidealities in very large spur gear train

    Hello, I am having some trouble with theory not matching practice in a spur gear train that I designed. The train consists of about 200 1" stainless steel spur gears held in place in a horizontal plane between two plates. They are driven from above by a vertically mounted motor connected via a...
