Hi,
anyone having any idea about what's the best position of the crank(s) in relation with the torque sensor?
If you look at the pictures you see that there are #2 main positions of the square interface on the axle in relation with the torque sensor (depending on how you rotate the axle inside the torque sensor):
resulting the following possible crank positions:
This is true for both the left & right cranks (depending of how the axle was machined).
The HK2214 bearings at both ends of the torque sensor have a little bit of play in them, the torque sensor flexes as there are forces applied: foot pushing on the left/right crank, electric motor driving the main toothed wheel (even if the torque sensor it's not rotating then), the force needed to drive the back wheel of the bicycle.
I think there must be some combination of left/right crank position in relation with the torque sensor (specifically the cutout in the "pipe" area) so there are greater or smaller forces trying to take apart the torque sensor.
Maybe there is some software that can be used to simulate forces at the torque sensor level.
What do you think?
