For speed,
(RPM/60)*(Diameter*3.141) = in/sec
For angle,
(teeth on slip gear/teeth on cata gear)*360 = angle
Angle as in the arc of the shot? Because I just calculated this and I got a number higher than 90…?
Here the equation: (22/60)*360= 120
It’s a 36 tooth gear that will have 7 gears cut off each two sides.
Two slips on the gear?
Then it would be (11/60)*360= 66 degrees
Sorry if the formula was a bit weird, here is a revised one:
(Teeth per slip/teeth on cata gear)*360 = degrees
That is better than having a 12 tooth gear in the middle of the 36 tooth gears, the 12 tooth gear would be spinning at 1200 RPM which would create a crazy amount of friction unless it was on a screw joint.
Due to the advent of the new 2’’ Omnis, though I doubt they will be used a lot, I took the liberty to update this thread with some new gearings (some CAD screenshots not included, I’ll try and make some, but I’ll take any you guys have). I have ommitted any gear configuration with anything larger than a 36 tooth gear attached to the omni wheel.
2" Wheels
700 rpm (73.29 in/sec)
200 rpm motor geared up 84:24 (7:2)
Extremely bulky and fast, I would not recommend this.
600 rpm (62.8 in/sec)
600 rpm motor 1:1 direct drive
Any other gearing will just result in more friction, and this would be the best one on these wheels in my opinion.
Plenty of configurations with this one, hence the absence of a CAD screenshot
i feel like the new wheels could be decent if you ran 2 per shaft and 45 degrees apart
Yea, I agree with that. I think their biggest use will be for tracking wheels.
I honestly might order 20 of them so I can run 600
im also excited abt the new mecanum. Mecanum has always had potential imo the wheels just sucked, but since they are coming out with new 4 inch mecanum wheels soon it could be rly interesting because if they keep the circumference to roller rate that they used on the new 2 inch ones it would have 12 rollers which is significantly more than the current 8 and would allow for them to roll much more smoothly and potentially get some use at a higher level than they are currently.
If we go 8 motor drive later in the season I might do 480 on 3.25. It seems a bit fast but it might be really good for navigating the field very quickly.
6.8 feet per second seems like alot…
Faster than the fastest drives
More powerful than Oh wait torque issues…
Able to fly after jumping the barrier!!
Night and day he fights for triballs, matchloads, and all that is metallic and janky
No one can stop him!!!
Are there any good 4 green motor drives? We don’t have access to 48,72,24 tooth gears
I would say 333 rpm on 3.25 in wheels. It uses 60 (connected to the motor) and 36 (connected to wheels) as the gears.
My team uses this and it works great on four motors
We’re currently ordering 3.25 in wheels but does this still work for 4 in
imo it works better on 4 inch wheels than 3.25
Oh okay and this ratio still gives a lot of power too right.
Actually take back what i said i don’t think that 4 motor 333 works better on 4 inch, with 6 motors it is better. With 4 motors you can try 72:48 on 3.25 or 4(4 is much better) if you have limited gears.
Sad no 72 or 48 gears for us :(. But ill see if my mentor can order some
