My question is simple: I want to make a dog clutch system for a wakeboarding cable system and was wondering if a flex (spider) coupler could used? The power, velocity, torque is similar to a go kart / lawn mower, atv etc.
Dog clutch:
Flex Spider Coupler (the one with a nylon/plastic insert)
Background: I am working on a unique wakeboarding cable system design which goes forward and backwards at the same speed. The idea is to build a hybrid winch/cable 2.0 system which uses a 6.5 HP 3600 RPM engine to pull a 200 pound person 30 km/h (spool is 0.3 m radius). Ideally a system would have a neutral, forward and reverse, but forward and reverse alone would also be acceptable (with a skilled operator).
I can easily gear down to get the required speed/torque but I currently can not find a transmission/gear box which offers reverse at the same or similar speed ratioto forward. The two options I found are a:
1/ TAV (Torque-A-Verter) Style Reverse Gearbox which has a 1:1.3 forward, 1:2.6 reverse and a neutral
2/ Planetary reverse gearbox which has a 1:1 forward, 1:1.5 reverse and no neutral.
If this is not possible, I would also be interested in alternative solutions.
