[Solved] Leaning-Mechanism with a 1/2 reduction for Servos

[aFrInaTi0n]

Hello together,

 

I currently am in search for some reduction for having a servo doing its 90° max angle being converted into 30°- 45°. Goal is to have another part do a leaning of those wanted 45°.

Also the middle 0° position should not have the teeth-offset which would be created by just using a pair of gears. gearracks and part 24014 would be possibilties to conquer that.

 

Current (already working out) idea is this:

(Hint: bottom axle is the one of the servo, upper part shall be angled to 45°, stud distance of servo output and the angling point should be kept, or max increased by one stud)

 

Any ideas how this may be compacted any further?

 

Best regards

I’m confused, why do you need all the additional linkage? You can just figure out the gear ratio directly off the servo to give you a different angle.

Sorry for confusion   - I would like to have a solution which will also work out for aftermarket servos which only have the full 90° end position, as we a ll know the astronomic prices of original PF servos..
Goal of this is to use the upper part for a leaning mechanism which would have a Buwizz unit mounted to move the center of gravity of a motorcycle.

My problem is, I could use gear reduction but the smallest and best fitting 2:1 config is 12t-24t - but this creates an stud offset to one side horizontally.

Hope I clarified a little.. If not, I need to explain further..

Edit: screenshot of the direction is wrong, but was the easiest to take the screenshot out..

maybe something like this where the valve lever is your tilting body?

with the requirement for the mechanism to work with off brand servos too, it would still move by 90°.

I have currently no time to rebuild it digitally nor attach it to the servo, maybe this will clarify the intented usecase:

@efferman's solution works (blue 3l liftarm goes to blue pin connector)

Yeah, I had a call on our companies on-call-duty and realized inbetween - but couldnt immedialely edit.. Thanks, this is much more that I could have asked already haha!! ♥ so thanks to both of you.

Edit: I forgot about the generic build help thread... next time I hopefully will post there... *note to myself..
