Hello, I am attempting to obtain a 5000:1 Gear reduction ratio. I'm looking at using worm gear reducers. To give you a sens of scale, I am attempting to spin a bicycle wheel at an ultra slow speed (0.001mm). The Motor I have has a torque of 0.5NM - 7.4NM However, I am a total noob when it comes to gearing and setting it all up. I have a very high budget and I only access to the products listed at http://www.sdp-si.com/web/html/products.htm. Any help would be appreciated. I was actually looking at using their prebuilt speed reducers but I don't think you can put them in series as their max input torque is much lower than their output torque causing failure(?). Thanks a bunch.
