VEX Worm Gear

VEX Worm Gear

The worm gear provides high gear reduction in a very compact space. For example, adding a 24 tooth worm wheel to the worm gear gives you a gear ratio of 1:24, meaning that the torque (turning force) is increased by a factor of 24, but the speed of rotation is 24 times slower. To achieve this with regular gears would require you to stack gears. Worm gears also resist backdriving (when a load is too heavy, it turns the motor backwards, causing damage). Please use this with the 24 tooth worm wheel. Using a regular gear is possible, but it is difficult to get the gears to engage firmly (basically, they slip all over the place). *Update: I noticed that I have the threading direction backwards. This should not really be an issue for most applications. I changed the worm wheel to match the backwards direction. Just FYI. #FTC #gear #robot #VEX #VRC #worm_gear
