This year, our team is spending more time trying belts to do reductions (as opposed to something like VersaPlanetarys). We’ve been using GT2 belts from VexPro along with pulleys that press fit onto motor shafts.
Ours tests with 775pros and BAG motors worked pretty well, but when we tested with the NEO 550 today, we sheared the motor shaft off clean (motor was being used at a 5:1 for intake). We used calculators for tension, but there was still a lot of force on the shaft.
Have any other teams successfully used belts directly mounted to 550 shafts? The specs for the 550s look great, but the shafts are smaller than we’d like.
