Long time no see hunn?
I'm almost finished mounting a magmotor dc motor/planetary gearbox onto my ATV steering shaft. I have a timing pulley on the shaft and another pulley on the output shaft of the motor. In order to protect the expensive gearbox I coupled the gearbox output shaft and the pulley shaft with a spider coupler.
Everything was good, until I had to actually mount the thing to the ATV and the only way I had was to mount it upside down. Needles to say, the pulley gets disconnected from the spider because of gravity.
Can you think of any other type of coupler that 1) will absorb some impact2) it's not too expensive 3) does not get disconnected if forces are applied outwards
The other thing that crossed my mind is: with a timing belt, do I really need a spider coupler (instead of a rigid coupler)? Doen't the belt work as a shock absorber? Will it skip a teeth if a sudden and strong torque is applied to it? (i.e. the wheels hit the curbside at an angle).
I don't know if you'll be able to get the picture from my summarized words, if not, ask for clarification.
