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.
This study systematically evaluates how material selection, progressive wear, and grease lubrication affect the noise, vibration, and harshness (NVH) performance of polymer gears, providing new insights for designing quieter, more optimized transmission systems.

The paper examines how optimizing asymmetric gear tooth geometry through Direct Gear Design can improve load capacity, efficiency, and compactness in EV gearboxes, surpassing the performance limits of conventional symmetric gears.
.
This paper examines the transition from internal combustion engine (ICE) vehicles to electric vehicles (EVs), highlighting the distinct gear design requirements for each and presenting a comparative case study of gearbox configurations in a 14-ton commercial vehicle.
.
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.
.
Variable loads resulting from a working process, starting process, or operation near a critical speed will cause varying stresses at the gear teeth of a drive system. The magnitude and frequency of these loads depend upon the driven machine, the motor, the dynamic mass elastic properties of the system, and other effects.
This article describes a cloud-based process and machine component monitoring system called ARGUS. The term “swarm” is used for a large population of gear-grinding machines of individual and independent customers connected to the ARGUS system and the ARGUS cloud. These “swarm” machines permanently feed their anonymized process data into a common cloud database. Reishauer uses this database for big data analytics to discover patterns that indicate successful process and machine component behavior patterns worth integrating into the ARGUS algorithms and propagate them across the complete ARGUS customer base.
As the gear and power transmission industries evolve, companies worldwide face a critical challenge: how to ensure the workforce is skilled, prepared, and ready to tackle increasingly complex manufacturing processes. From digital manufacturing and automation to generational turnover, the demand for technically proficient employees has never been higher. In response, the Motion + Power Technology Association (MPMA) redeveloped its Workforce Training Series, modernizing its most popular on-demand courses with updated content, high-quality media, and a flexible, self-paced delivery model.
Since I have had the privilege of visiting numerous gear plants and research centers in the U.S., as well as 170 in 33 countries, and I closely watch the progression of technology, I wanted to share my observations about some technological advancements. For the purpose of this article, I will focus on three key areas: Robotics, Machine Tools, and Heat Treating.
This white paper explores how the use of an automatic tool change system can boost productivity in the grinding process. When manufacturing large gears, the demands regarding surface quality of the ground tooth flanks are increasing.
