Andymark Planetary Transmission...
Is anyone else using the Andymark Planetary Transmissions for drive or anything? Does anyone have any comments or thoughts from experience with them?

Re: Andymark Planetary Transmission...
Sorry, we're using Banebots. We looked at using AM Planetaries but decided Banebots were the way to go. I currently don't know the technical reasons why.

Re: Andymark Planetary Transmission...
We are using Both of Andy's Planets.
We are using a CIM with his GEM Planet and we love it. Very sturdy construction and more reliable in my opinion than banebots IMO. Our last few tries have been horrible, but I do like the promise of the p60's We are also using his Planet for the FP in our drivetrain. Team 1323 is very happy with AM's products. -RC |
Re: Andymark Planetary Transmission...
The banebots transmissions we've used have been junk. I don't know about the P60, which is supposed to be better, but I would never choose a banebots planetary over an AM Planetary.

Re: Andymark Planetary Transmission...
AM Planetary is a really useful gearbox for the drivetrain or any kid of FP/CIM ganging. I haven't heard of one failing, nor has 1714 / 2791 ever had any problems with them.
In general, if it's an AM product, it's reliable. |
Re: Andymark Planetary Transmission...
Yea I agree with the rest of the comments, the AM planetary is a great transmission especially for the FP. Although we did have a bit of trouble putting on the pinion gear.

Re: Andymark Planetary Transmission...
Banebots have gone a long way to improving their planetary transmission (P80) in terms of durability and design since their initial introduction introduction in the KOP several years ago. They responded with changing the design based on team feedback, adding a thicker and hardened steel output plate, tie rods to hold the end plates tight and square, centering bosses on the end plates for the ring gear, and steel internal gears. We have used them consistently with no failures, and will continue this season as well. That coupled with their lower cost, and if utilized within their design limits, they will do a good job. :)

Re: Andymark Planetary Transmission...
We're using an A-M GEM500 planetary with a CIM for the first time this season - we expect good results. Per Andy-Mark, the GEM's will be back in stock tomorrow. If you are only asking about the "A-M Planetary" (a separate product from the GEM) because the GEM planetary is not in stock, just wait until tomorrow and check their site.
The Banebots P60's are very reliable. Lightweight. Compact. We used 3 of them on last year's robot with zero failures of any kind. We'll be using two more again this year. We've actually never had any major problems with Banebots since we started using them in 2006. The P60's are definitely a big step up from the previous designs. The only caveat is some pretty significant lead time in getting them built and delivered. I suspect increased demand due to less motor diversity in the kit. |
Re: Andymark Planetary Transmission...
Banebots planetary is definetly super reliable. my team has reused the same 4 gearboxes for drivetrain on our robot for 3 years running. not once have we experienced any problem. People just have a bias against banebots because of a bad gearbox along time ago(maybe not that long). But people who think banebots have zero quality really are just close minded to the new gearboxes that they have made.

Re: Andymark Planetary Transmission...
We had some Banebots planetary transmissions to drive our robot in the 2007 season, but then they failed in the elimination rounds at the Wisconsin Regional. We mounted some Fischer Price motors into the P60's last year and didn't have any problems with them. From what I've heard and read, Banebots has done a good job of improving their transmissions and listening to feedback. We are using one Banebots P60 gearbox on this year's robot, one AndyMark Double Doozy, two toughboxes, and one nano toughbox as of right now.

Re: Andymark Planetary Transmission...
we're using what I assume are the andymark planetarys (the '07 KOP ones)

Re: Andymark Planetary Transmission...
Could anyone tell me how to mount a FP motor to the this kind of gearbox? I'm not sure if we're allowed to yank the gear off, and if so, how?

We always use an Arbor Press to do this, but you must be very careful no to bend the shaft of the motor. For more info try these threads: http://www.chiefdelphi.com/forums/sh...ight=FP+pinion http://www.chiefdelphi.com/forums/sh...moving+FP+gear |
