I've been pondering the theoretical limits we face when trying to maximize either gear speed or torque in mechanical systems. It truly seems like there's an inherent trade-off dictated by material properties and manufacturing tolerances. as an example,trying to achieve extremely high gear ratios in a small space inevitably leads to incredibly fine gear teeth,which become susceptible to deformation and failure under high loads. Conversely, massive gears designed for immense torque are limited by the centrifugal forces at high speeds, potentially leading to catastrophic structural failure.
Are there any particularly captivating or unexpected limitations you've encountered in your own explorations of gear speed and torque? I'm curious about specific examples, perhaps involving unusual materials or novel gear designs that push the boundaries of what's currently possible. I was reading about some experimental microgears using silicon carbide that apparently handle really extreme RPMs, but their torque capacity is ridiculously low. It makes me wonder if there's a basic limit imposed by the second law of thermodynamics that prevents us from simultaneously achieving arbitrarily high speed and torque in a single system.
