Make it Real: Grappling Hook Winch (BUILD)
It's finally done! SUBSCRIBE to see the final test! ► http://goo.gl/MU4hNA
Building steps (expand the description):
-We got 2x 2.7kW motors (https://goo.gl/2ppF6U), 2 ESCs (https://goo.gl/VZiIjg), batteries (http://goo.gl/pkSN00) and a servo tester (https://goo.gl/istRF8) from HobbyKing
-We designed the system and then machined the parts using our Tormach PCNC 440. https://www.tormach.com
-The revolving spool was machined by Peter on his 5 axis CNC machine. Check out his video to see it machined https://www.youtube.com/watch?v=WYxXY0_hgU4
-The motors are run in parallel with a timing pulley to keep them in sync. Note that you cannot run 2 brushless motors from 1 ESC. We are using 2 ESCs controlled by the same signal. The motors turn a worm and spur gear with a 20:1 reduction ratio. The motors run up to 10,000rpm meaning the output shaft is running at 500rpm
-We designed a custom revolving spool to ascend the rope. The rope wraps around the drive spool and an idler spool, 4 times to prevent slipping. If you wrap a rope around a driven shaft, it will wander to 1 side and then tangle which is why we used 2. The 2 spools have grooves to guide the rope along the wraps. Additionally, the drive spool has notches within the grooves in order to grip the rope better. An idling bearing pinches the rope to the drive spool on the output in order to keep the tension.
-3d printed covers were made on our Taz 6 (http://amzn.to/2lvxtCz) with the new Moarstruder (http://amzn.to/2kXKxCE) for a quicker print.
-All parts were printed using PETG from fillaments.ca http://filaments.ca/?rfsn=362416.42f3f
-The winch assembly was bolted onto a custom weldment on the gun.
-Now it is time to test.
