![]() ![]() Currently my teams photo gallery is under construction so I don’t have any better photos of our 2007 or 2008 drive train, this is all I could find. Both systems experienced 2 regionals, Championship and multiple off season events and still have yet to show signs of failure. I cannot verify that a plastic one will definitely work, but my feeling is that it probably would depending on size, mounting style, etc.ĭuring the 20 seasons Team 612 used plastic pulleys with the inserted aluminum hub. I havent used them in a drivetrain, but what seems to fail in drivetrains is the belt. They are a lot lighter than the aluminum ones (freeing up machining resources for more important things), and at high RPMs are noticeably quieter than roller chain (compared to our Aim High robot). I’ve been using some of these with 5mm pitch belt on the shooter (as shown below) and ball intake on 228’s robot this year, and was considering them for the drive train in the future. Has either 234 or 612 (or any other team using belts on their drive train) used non-aluminum timing belt sprockets? Or more specifically, has anyone used the SDP/SI (or similar) timing belt sprockets that have an aluminum Fairloc/T-Insert hub embedded inside a polycarbonate timing belt sprocket on a FRC drive train? Our object was to determine if there was a “best” drive type for FRC robots. ![]() Chain Drive on several parameters, working with some basic Design of Experiments principles and working to make sure we would obtain objective, unbiased results from the testing. This paper is a test report of work completed by Team 234 during the fall of 2008. The design, fabrication, testing, analysis and reporting were completed by Team 234, Cyber Blue, in the fall of 2008.įIRST Robot Drive System Analysis - Team 234.pdf (1.17 MB) We used some basic design of experiments processes, ccreated test plans and processes, and then completed the testing and analyzed the data. We compared weight, performance, efficiency, noise levels and other parameters. We compared several parameters in “side by side” testing to determine the “best” solution for FRC robot drive systems. ![]() This is a formal test report of belt drive vs. This paper contains the results of the testing, how we defined our tests, and the test processes. Team 234 completed a performance evaluation of belt drives and chain drives for use in FRC robots. Thread created automatically to discuss a document in CD-Media.īelt vs. ![]()
