So I’ve somehow managed to find time to create this over the past few days, even though I just started classes at Kettering. This module has taken inspiration from 2910s swerve largely, along with some from team’s modules such as 33, and 2767 (even though this doesn’t resemble their swerve that much).
It uses the AM 20:40 bevel gear set, a 3" Colson, 4" available from SDS, and then a NEO for the azimuth, and one for the drive. All the gears (minus the encoder gears) are just Vex gears, and all the pulleys minus the large 60t for the azimuth are COTs. The main 3/8" plate is planned to be made out of Nylon, and the upper plate where the motors mount out of aluminum (to act as a heat sink). The large azimuth pulley is planned to be made out of Nylon (or a similar plastic, possibly Delrin), and water jet or laser. The small diameter shafts are 8mm steel shafts just to allow for a smaller pulley on the azimuth, and to allow for no modification of the 20t bevel gear. It currently uses a SRX Mag Encoder for the drive, and then an AM Absolute Encoder (setup 1:1) for the azimuth. The main base plate is laid out in a way to allow for the use of a 6" x 12" piece of Nylon. I didn’t do any weight reduction to the motor mounting plate since there are only 3 standoffs supporting it, and might as well keep surface area high for use with NEOs.
According to Solidworks, the module weighs 4.7 lbs, and the only thing I didn’t attach in CAD were the snap rings for the end of shafts (nearly every shaft has 2).
Should I add more standoffs to the top plate to support it better?
And is it worth removing weight from the top plate?
Also, any other recommendations or concerns about the design?
Let me know if the CAD link doesn’t work, I don’t think I’ve posted a ton since the move to the new site.
