Our intake can run just fine on a 200rpm Green motor insert, but whenever I attempt to run the intake on a 600rpm blue motor insert the intake will not spin at all. Because it is a four-row intake. We have figured out that the reason it will not work is because of friction rubbing on the axles. Since I started I have added Bearing flats to every axel still on the intake. I tested the 600rpm motor and it still will not spin. Any tips on how to de-friction our intake would be helpful.
unchain each part of the intake and test each shaft until you find the culprit, then realign the bearing or switch the shaft. Also, make sure your lock collars aren’t tightened down to hard
Keep in mind that blue carts have significantly less torque as a sacrifice for speed. Even if you fix all of your friction issues, it may still not be enough simply because the motor is too weak. If that’s the case, try gearing down a 600rpm cart or gearing up a 200rpm cart to find the right balance of speed and torque.
A 600 RPM cartridge should be able to handle 4 shafts for an intake regardless. Make sure whatever you are mounting your bearing flats and shafts on are aligned properly. Make sure everything is parallel and perpendicular. This will probably reduce most of the friction that you are experiencing.
One other thing to check… Make sure that your chains are not too tight. I had a group with a similar problem this year. Adding a single link to the chain fixed it. (They also had to add a roller to alter the chain path a little to take up the slack.) The overly tight chain was flexing an axle and forcing it against multiple bearings.
We know it will work with a 200rpm cartridge but are aiming for a 600rpm cartridge. at the moment the bot is at a team member’s house and we do not have any gears for the bot. Trying to make do with what we have. thank you for the tip.
