Operating for long hours, under extreme loads, in high temperatures and dusty environments, ongoing wear is a significant challenge for open gears. This can lead to unplanned downtime and reduced equipment life—creating a barrier to effective operations. Leading mining and cement companies use advanced grease technology and technical inspections to help prevent open gear failure, optimize service life and ensure the smooth running of their operations.
This paper will review the development process, current research status, characteristics, functions, and measurement methods of TE. It will analyze the difficulties and core issues existing in the basic theory of TE, clarify the limitations and deficiencies of TE, and explore ways to overcome the shortcomings of TE.

Thanks to material development and additive manufacturing opportunities, it’s important for the gear and power transmission industries to monitor the trends, technologies and future forecasts in the powder metal market.
For the research developed in this work, an existing simulation model of the generating gear grinding process based on a penetration calculation approach is used. Further, an extension of the model considering a realistic modeling of the grinding worm topography and the macro movements of the grinding worm during the process is presented. The result of the simulation is the microinteraction characteristics throughout
the grinding of the gear flank. In the end, the information about microinteraction characteristics obtained will be used for the calculation of force and energy in generating gear grinding.
A combination of international regulations and consumer expectations is driving the demand for reduced noise on all drivetrain components. Further demand is driven by the growing trend towards EVs and HEVs, where noise from ICE is intermittent or no longer present, and the contribution of transmission noise to overall vehicle noise becomes dominant.
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.

CNC Gear Machine Tools: The Strategic Case for Re-controlling AND Re-building Versus New
Setting up an in-house heat treating operation allows businesses throughout many industries to harness this powerful technology and create better-quality metal parts. In this article, Surface Combustion discusses the biggest cost considerations involved in purchasing in-house heat treating technology and investment strategies to ensure you maximize your ROI.
Efficiency and process reliability are critical in modern manufacturing—and this is exactly where the EMAG VST 50 excels. A standout feature: the fully automated tool change. Thanks to an integrated robot, the tool change takes less than 90 seconds—all while production continues uninterrupted! The tool magazine ensures a smooth process: it swivels outward, the robot swiftly and precisely replacing the tool.
Marposs Corporation, the North American headquarters of Marposs S.p.A. (Bentiviglio, Italy), has announced the appointment of Luca Matteucci as its new president. In this role, Matteucci will be responsible for defining and executing company strategy in alignment with Marposs S.p.A., providing leadership for the North American organization, overseeing budgets and personnel, and evaluating overall performance to ensure achievement of corporate objectives.
Weiler Abrasives has expanded its color-coded product lineup to include some of its most popular brushes for stainless steel. The color-coding helps stop cross-contamination in operations working with both carbon and stainless steel by making it easy to identify the correct wire brush—even during operation. This helps operators get the job done faster, safer and better.
With manufacturers across North Texas struggling to hire and retain production workers, OnRobot will host the “Build your Automation Roadmap” event in Dallas on February 19th, bringing practical automation solutions directly to the region’s manufacturing community. The free, in-person event is designed for manufacturers in sectors such as metal fabrication, CNC machining, electronics, aerospace, food & beverage, and industrial equipment manufacturing — industries that form the backbone of the DFW manufacturing economy and are among the hardest hit by ongoing labor shortages.
