(...) A word of caution - the worm gears are certainly great for large gear reductions in small spaces, and it is usually easy to brace them well, but they have one disadvantage over a traditional gear train - they create more friction, and are (...) (24 years ago, 22-Sep-00, to lugnet.robotics)

(...) Would the friction created be that much of a problem? Would the loss in efficiency be that noticeable? (Note: These are not rhetorical questions so a response would be appreciated :-) Jude (24 years ago, 22-Sep-00, to lugnet.robotics)

(...) As ever, the most appropriate response to this question would have to be "it depends". In "real" engineering applications the answer is generally yes - certainly when I have used linear drivers based on worm screws in the past, their (...) (24 years ago, 22-Sep-00, to lugnet.robotics)

Im ahead of you there, I already did that :p. I need to add even more torque. The the current setup is this: worm to central 40pt gear, 40pt's axle is connected to one 8pt gear on either end and then after that a 16 (i think)on each end also. The (...) (24 years ago, 22-Sep-00, to lugnet.robotics)

(...) 1:40. There's a single thread on the worm, moving one "tooth" per revolution. That gives you the same ration as 1 tooth gear. As has been discussed before, the characteristics of this worm gear reduction will be slightly different than (...) (24 years ago, 22-Sep-00, to lugnet.robotics)

According to "The Art of LEGO Design" a worm gear is best used at high-speed, low-torque points in the drive train. In other words, drive the worm from the motor, then do any further gearing... Unless your normal gear train is trading torque for (...) (24 years ago, 22-Sep-00, to lugnet.robotics)
