Abstract: This paper introduces the construction theory on ball globoid worm drive. Using the meshing theory, it analyses forming theory on globoid worm setting hobbing cutter, processing ball worm gear theory with this setting hobbind cutter. Using the meshing theory, it obtaines two border function in the processing of the ball globoid worm. A result of initially testing was given the gentle readers.
