Team 41 2019 Preseason Drivetrain Design Release
grabcad
This year Team 41 RoboWarriors decided to explore various unfamiliar areas of mechanical design of a drivetrain for the First Robotics Competition.Explored Areas/Topics:- Rivets versus threaded bolts- Two Speed shifting gearbox- Inverted two CIM gearbox- Timing belts instead of chains- Box Aluminum frame instead of plates with 8020 ribs- Using the new Tormach PCNC1100Notes about the Design:- The gearbox ratios are 15:1 and 6.6:1- The clear green plate is space allocated for electrical components- The ball shifter transmission is from Vex Robotics- Shifting pistons are custom ordered from Bimba- Timing belts and sprockets are inside the 2"x2" box aluminum (24 tooth HTD sprockets with 655mm length 5mm pitch HTD belts)- 1/4" rivets are used to assemble box aluminum frame- All iterations of the gearbox and drivetrain models are included in the upload (there may be a few errors in generating the assembly in earlier models)Design Discrepancies:- The compressor shown is not actual compressor used- Actual compressor is a similar size and didn't have a downloadable 3D model (90C VIAIR Compressor)- Gearbox in latest drivetrain model is not the latest version- Omni-directional wheels may be used in the front, back or both as needed
