Zarautz, Spain, might seem an unlikely place for a precision gear manufacturer. This beautiful coastal town in the heart of the Basque region is known for its beaches and considered among the top surfing destinations in the world. Surprisingly, the relaxed holiday atmosphere and laid-back surfer ‘vibe’ turn out to be highly conducive to the production of gears. It is here that you will find Engranajes Juaristi, a renowned gear producer, owned and operated for over 65 years by the Juaristi family. The company specializes in the production of high-precision external and internal gears up to 1,200 mm in diameter, as well as worm gear sets, spline shafts, and other transmission components for everything from wind turbines to tractors, machine tools to trains. Significantly, 30 percent of the many thousands of gears produced by Engranajes Juaristi annually are in lot sizes of just one, and the average lot size is just seven parts. It’s a bold strategy that attracts business and gives them a competitive edge. It also requires machines that can deliver faster cycle times and more flexibility.
A method to calculate pitch cones for hypoid gears using macrogeometry parameters—similar to non-offset bevel gears—while accounting for the added complexity of hypoid offset, tooling, and cutting technology is explored in this paper.
