  1. Re: Is there an alternative to using pillow blocks?

    Ok that is exactly what I needed to hear. I'm going to rebuild the frame and add some plate in the middle to mount the pillow blocks to. This will spread them about 12-15" apart from each other. The...
  2. Re: Is there an alternative to using pillow blocks?

    Exactly. Even without any payload, they are being pulled out of place by the track tensioning around the drive wheels. If I don't tension it to the level of failure, then when I add the payload they...
  3. Re: Is there an alternative to using pillow blocks?

    Thanks tician, It is the bearings that are moving out of place inside the housing. When I spoke to the bearing people, they said it was common for them to shift but unlikely if I'm using 2.
  4. Re: Is there an alternative to using pillow blocks?

    On my original post is a picture of the application. I have the 2 pillow blocks side by side and the wheel and sprocket are mounted to the shaft on the outside. I know that the pillow blocks are...
  5. Re: Is there an alternative to using pillow blocks?

    Thanks guys,
    Every pillow block or mounted bearing I've seen has some sort of self aligning feature. I've bought 2 different brands and they both shift out of place when I tension the track.
  6. Re: Is there an alternative to using pillow blocks?

    Thanks,
    We are going to see if we can weld the bearing to the housing, if that doesn't work, I think we'll weld a bearing in a piece of plate and try that.
  7. Is there an alternative to using pillow blocks?

    I'm currently using 2 pillow blocks side by side to hold my drive shaft. The pillow blocks are constantly slipping out of alignment one way or the other. What I'm wondering is, are you guys using...
  8. Re: Need to build a tracked platform..Seeking advice

    Thanks Tommy. I'm going to order some soon.
  9. Re: Need to build a tracked platform..Seeking advice

    Yes, these motors are 700 watt 4 pole motors. I spoke with the owner of www.summitmowers.com , he builds radio controlled lawn mowers using the same mowers.
  10. Re: Need to build a tracked platform..Seeking advice

    Here is a link to a short video of the project in motion. I think I'm going to have to figure out a sprocket and chain design to gear it down for more torque. I will also be getting the 160A motor...
  11. Re: Need to build a tracked platform..Seeking advice

    Thanks!
    Yes it moves quite well in forward and reverse on flat surfaces. It doesn't turn well at all. I'm currently using 12awg wire because that's what the leads on the motors are. I will go get...
  12. Re: Need to build a tracked platform..Seeking advice

    Ok I'm back with more questions. I chose a set of wheelchair motors from a heavy duty Invacare chair that weighs 300lbs and can carry someone that weighs 500lbs. Since my payload will be around the...
  13. Re: Need to build a tracked platform..Seeking advice

    Alright thanks! I'll probably buy my batteries local so I don't have to deal with shipping.
    As for the motor controller, I'm ordering a Sabertooth 2x60 from Trossen's store and probably a 2 channel...
  14. Re: Need to build a tracked platform..Seeking advice

    Did you mean 2 12volt batteries in parallel instead of 1 24volt?
  15. Re: Need to build a tracked platform..Seeking advice

    Also, Let's talk batteries. I'm planning to go with the LiFePO4 battery and a 2x60 motor controller. Should I go with 2 12v battery packs with a charger or 2 24v with a charger?
  16. Re: Need to build a tracked platform..Seeking advice

    Yeah that's what I was trying to figure out. I didn't know if I needed a sprocket and roller chain or if I could just mount the motor directly to the drive wheel of the track.
  17. Re: Need to build a tracked platform..Seeking advice

    Ok thanks jwatte! That helps a bunch. These are the tracks that I am probably going with. I don't think I'll ever take this on an incline . The main purpose is to be able to steer it around to where...
  18. Re: Need to build a tracked platform..Seeking advice

    And...this is where my being a noob comes in to play. I thought with a geared motor, I could mount the sprocket of the track directly to the motor shaft. Are you saying I need to mount a pinion to...
  19. Re: Need to build a tracked platform..Seeking advice

    I got a quote for 2 gear motors from this place http://www.ampflow.com/ampflow_gearmotors.htm . They are pretty powerful but are way more expensive than the wheelchair motors. I'm not saying they...
  20. Re: Need to build a tracked platform..Seeking advice

    Thanks KurtEck! I will add that one to the list. Sourcing motors now. I don't know exactly how to calculate if they can handle the 800lb weight.
  21. Re: Need to build a tracked platform..Seeking advice

    This is a great quote to live by!

    Thanks for the advice, this is the kind of knowledge that I'm seeking. If the wheelchair motors are 500 watts each, are they not powerful enough to carry this...
  22. Need to build a tracked platform..Seeking advice

    Hi everyone. I need to build a tracked platform that will have what looks like a gun safe mounted to it. The "box" is 42" wide x 37" deep and is 800lbs. I don't need it to move very fast and I don't...
