    Fine-pitch worm gear questions

    Thanks for the tip Compositepro. Indeed, most telescopes are counter-balanced well, and balanced on their primary axes of rotation, however, this assembly will not be metering those axes. The assembly will be used to align those primary axes. Unfortunately, no counter-balancing is possible...

    Fine-pitch worm gear questions

    Thanks for your reply. This is puts things in perspective for me after looking at the size and weight of the planetary gearboxes designed to handle this kind of torque and realizing that this is a *large* torque. To reach my design goals, I will have to return to the method I started out with...

    Fine-pitch worm gear questions

    Ah well, mucked up my math again [upsidedown]. The load should be 600 lbs at 30" & 6" and 300 lbs at 15" & 6" Best Regards, Matthew

    Fine-pitch worm gear questions

    Thanks for your reply. It suggests to me that assuming I am able to find a shop that can hob the gear with an equivalent DP, I should be able to do this. I'm citing an absolute worst-case load that I doubt will ever be seen in real-life, and here's how I'm figuring the load. The heaviest...

    Fine-pitch worm gear questions

    This is not my main field, so I am hoping that someone here will be able to help me out with this. I'm working (in my spare time) on a metering structure for small astronomical telescopes (16" diameter main mirrors and less), and I have come to the conclusion that using fine-pitch worm gears...
