Lubricating greases are typically known for their use in a wide variety of applications such as rolling element bearings, automotive transmission joints as well as heavy duty chassis components; but can also be found very useful in the lubrication of gears. There are two types of gear families: the primary difference being open and enclosed gearboxes. The gears within a closed system are lubricated with grease within the system. Open gears are lubricated by grease or fluid separate from the piece of equipment. This paper will focus on the lubrication of open gears, utilizing both grease and fluid Open Gear Lubricants (OGL).
The digital transformation is fundamentally changing the industry, and digital twins play a central role. They enable real-time monitoring of physical systems, simulation of their behavior, and informed decision-making. A dissertation from the TU Darmstadt Institute for Product Development and Machine Elements (pmd) shows how the FVA-Workbench gearbox design software can be implemented as a platform for creating digital twins of industrial gearboxes. The results demonstrate how the combination of detailed modeling, continuous real-time calculations, and engaging dashboard visualization offers an efficient and user-friendly solution for the development of digital twins.
.Between trade shows including MINExpo and CES 2025, we’ve been treated to a great deal of new technology in areas like mining, agriculture, construction and heavy industrial components. Liebherr has modified its component portfolio to include digital measurement, electrification and maintenance-free technologies. Liebherr’s component product segment offers advanced solutions for slewing bearings and slew drives that meet the rising demands across a variety of applications and industries. These components are future-ready and play a vital role in making operations much more efficient.
.Automation has become a key driver of efficiency and productivity, regardless of industry. Among the most popular automation solutions are automated guided vehicles (AGVs) and autonomous mobile robots (AMRs). While both technologies automate and enhance material handling and reduce manual labor, there are key differences in their functionality, flexibility, and areas of application that set them apart.
.Curious about the state of robotics and automation? A day or two at Huntington Place in Detroit this spring should clear everything up. Automate 2025 attendees might see robots serving coffee, robots maintaining shop floors, robots building other robots. We have officially crossed the threshold from future possibility to practical application.
.The earliest example of a gear train dates to at least 2,000 B.C. when Chinese engineers built a chariot that used a complex planetary mechanism made of wooden gears to let a dragon head continuously point south when driven around (Ref. 1). In Greece, a surprisingly advanced Antikythera gearbox mechanism, incorporating at least 37 precisely crafted bronze gears, was built years later, between 205–60 B.C. (Ref. 2).
Modern spindle applications of rolling bearings require very high speeds and very high loads, often combined with poor lubrication conditions and/or high solid contamination. Examples of these applications are high-speed and high-cutting rate machine tools, where rolling bearings need to survive very though conditions. Rolling bearings in high speed and high load conditions might suffer from poor lubrication and potentially surface distress and adhesive wear.
Looking to reduce speed and increase torque—without the size and complexity of a compound gear unit? Discover how the W..9HG SPIROPLAN® delivers gear ratios over 2000 and torque up to 600 Nm in a compact, quiet, and efficient design.
