    Gear backlash —David Paule
   Does anybody have methods for reducing gear backlash? (25 years ago, 18-Nov-99, to lugnet.robotics)

         Re: Gear backlash —Jack Gregory
      Well, the standard way on worm drives is to load the end of the worm with a spring, so there is always contact on one "side" of the worm. Similar things can be done for spur gears, but they all involve loading the meshed teeth in one direction with (...) (25 years ago, 18-Nov-99, to lugnet.robotics)

     Hi. Russell is right. I did alot of this in my former life as a mechanical engineer, but it's not as difficult to do in LEGO(R) as one might think. Basically, one has to set up two parallel gear trains and then 'preload' them against each other by (...) (25 years ago, 21-Nov-99, to lugnet.robotics)

     What are we supposed to look at? Which of the many photographs on Bob's pages has to do with reducing gear backlash? I don't want to search them all. (...) (25 years ago, 18-Nov-99, to lugnet.robotics)
   
        Re: Gear backlash —Stefan Steinbauer
   Maybe this sounds strange: I tried to coat gears with liquid plaster. This works for some time - only with "less engaged" gear-trains and never try to coat both gears, because this ends up in a mess. The new liquid plasters aren't that sticky (...)
