Ghost in a machine ?

    Can there be such a thing ? at work there is a machine that constantly has
    breakdowns that defy logical explanation, human intervention has been ruled
    out as there are cameras in the room, and the only way the breakdowns could
    be man made is by some with tools and access to the machine

    No.
    So what kind of machine, and what's going wrong? If things are loosening up, it's probably vibration-related. Likewise if settings are drifting.

    There is a vending machine on campus that loves me. It gives me extra packages of chips and cookies.

    So Wooley, are you referring to a 1 1/2 inch Gilmer drive? Does it have a tensioner? Also, unless the pulleys are rimmed, the slightest misalignment of the axles will cause the belt to 'walk off'. A worn bearing could be enough to do it.

    The same style as this only bigger.

    And the guys who trade these drive systems and advise system design say no way can this happen.

    :grumpy: :grumpy: Do you think money is more important than your health? I'm sure those ghosts don't like you and they may want to kill you. :rolleyes:
    And I guess your employer is with them or perhaps he's a ghost himself.
    Anyway it's others(:tongue2:) who should be worried about you not me. :wink:

    Okay, that's what I was thinking of. The flanges (what I called rims before) should prevent the belt from coming off. If by 'jumping' you just mean 'slipping', it shouldn't be possible unless it's way too loose. Once again I ask if there's a tensioner on it. If not, add one (or maybe even one on each side of the pulley) and see if it helps.

    Sorry, yes there is a tensioner, one pully is driven via a 30mm shaft which
    connects to an 90 degree angle gear box 1:1 ratio, which in turn drives a
    simple rocking mechanism that picks a sleeve from a magazine and places
    it over a product, the sleeve is folded around the product down stream.
    both pullies have 8mm keys or maybe one is 6mm so they can not move on the
    shaft. we locked the mechanism up with a .5inch socket extension bar, the
    belt did not jump the main drive clutch operated first. :confused:

    Sorry, but you're going to have to explain the last part of that in a lot more detail. Partly because I don't know where/what the clutch is, and partly because you sometimes use different terminology than I do, I can't follow what you mean. "locked the mechanism up"? And by "socket extension bar" do you mean one that goes between the ratchet and the socket for more reach, or a snipe for more torque?:confused: :confused: :confused:
