  • 82/70 table

    I have a machine that the table seems to drop faster than the rest when setting a full rack. It sets the pins ok, but it drops down so fast that the pins wobble arround when the hit the floor. What do I adjust to slow this down a bit?

    The machine probably has a 14.5 gearbox on it......it is faster than the 12.1.

      Check to make sure table drive ass'y is not loose on the shaft, eccentric disc is not working its way loose, or missing counter balance spring on torque tube. Either way what is happening is gravity is pulling more than the controlled drop normally provided by the machine (when all components are in order and working properly.)

        Put that motor on the sweep. It wont affect the sweep like it will the table. If it is a faster gearbox. Or it could be worn splines or any of the above mentioned items Kat suggests.

          I would also check the table springs themselves. Over time they will lose thier original length and stretch, causing a weaker resistance to the the table as it drops.
          Possibly 1 or both spring mounts could be worn also.
          It's been awhile but I have much more to share!!!

            One word of warning... If you're going to mix gearboxes, be cautions putting faster ones on the table and slower ones on the sweep... We had problems with ours doing that... the table can run down faster than the sweep can get out of the way, and it interlocks (or in the case of a spotting cycle, rips the pins out of the 1-3-2 and flings them up the lane).

            Fast of the sweep and slow on the table is nice... sweep cruises through and clears the table with plenty of time to spare. The only thing I had to do was slightly advance the sweep cam so it would stop neatly... with a fast gearbox on it, it has a tendency to "jump" if it stops right as the sweep knuckles are locking up to lift it out of the way at 270.

              We have plenty of fast gearboxes where I am. All on the sweeps or both on most machines with them. Put a slow sweep with a fast table and you're asking for interlocks. Keep your cams adjusted so the sweep doesn't hit the head pin on the way back and a fast sweep slow table will be just fine [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

                we have had a couple of tables do this. fine one day not the next. all ive done is swapped the mtrs over, but is this really solving the problem or just avoiding it until it rears its ugly head again?

                  Also, if the motor has been changed lately, look at the nameplate and make sure it's not a 50hz only head.

                    Try this: from the front, operate the table with TA1, release it when the table is half way down. Does it coast on down to 180? If so, and you do not have an electrical braking problem, then I would suspect your gearbox is weak. This can cause the speed-up by the weight of the table forcing the motor.

                      sounds like 14.5 gearbox. I keep a couple of those gearboxs on hand for discution pieces. Man they can realy move.
