What is the purpose of the spring on output shaft?

Postby Dan Lumbye » Tue Jun 07, 2016 4:43 am



Hi

I wonder, what exactly is this mechanism good for? I know it´s the shaft and it transfer power to the final gear, but what about the spring and all that? Can anyone explain to me please :-)

It's designed to absorb shocks in the drive assembly. Acceleration/deceleration would (allegedly) be a lot rougher on the shaft/gears etc without it. Also the ride would (again, allegedly) feel 'jerkier'.

Notice that the mating connection is tapered?
With the spring to keep It centered,when torque is applied,this allows the initial twisting torque to be absorbed by the spring rather than the coupler.

This is also where the infamous 'half-turn clunk' comes from on take-off. Caused by the spring getting weak.

'Impossible' is just a level of difficulty! The only stupid question is the one you didn't ask first!
