Re: New video of my Centaur [TANKS]

future tank

The next tank for my dad is designed to be about 85 lbs.  I have not received an answer about what gear reduction I should use on it.  At 6 to 1, it would put about 450 inch lbs of torque on the sprocket at 650 rpm. at 8 to 1, It would have 600 inch lbs. of torque at 500 rpm.  This is a rough answer considering I did the calculations 3 weeks ago.  It will be powered from ev-warriors at 24 volts.  This will be a 31 inch tank.  Each track will be a tts 3 inch wide.  4 road wheels on each side.  the drive sprocket will be 4.5 inches diameter.  Can I get away with a 6 to 1 reduction without stalling my motors?

 

current tank

My current tank uses 2 npc-02446 motors with an npc gear box that connects to a 3 to 1 chain drive reduction #35.  The drive sprocket is 4 inch diameter.  My current tank runs at 24 volts with 18 ah in the loop.  The motors get warm after about 5 minutes of runtime.  I still need to do a "kill the batteries" runtime test on it.  The sprocket is calculated to spin at 500 rpm without resistance.  I get the video as soon as I do the test.
