That sounds like a plan.....
Some things to consider: The 12:1 and 16:1 output planet carriers are different, because the planet gears are a different size, so the pins are in a different location. Would the replacements be available for both the KOP 12:1 and the upgrade 16:1 transmissions? or would teams have to settle for using 12:1 only?
If you're not familiar with the transmission design, it is a two stage planetary, with a 4:1 first stage, and a 3:1 second stage. An upgrade 4:1 second stage is available from Banebots, and apparently some teams have decided to use it, and apparently it has the same problem with planet carrier plate failure under some conditions. The stages are mostly interchangeable, except that the pinion for the CIM motor is only made for the 4:1 stage (as far as I know), and also I believe it is the only one that will fit in the motor mounting end of the transmission.
Should the replacement plate be made significantly softer than the shaft, to act as a sacrificial part?
Would it include the planet gear pins, or would the teams have to press them out of the old plate, and into the new plate?
Is anyone going to consider the end play issue now, or wait until it causes problems in regionals?
It's hilarious to watch this conversation about a box which probably has a 95% chance of being robot batteries turn into all kinds of bowling ball conspiracies. - artdutra04 [more]
