Reducing Linear Bearing Wear

To get the longest working life out of a linear bearing, keep it clean and well lubricated. This common-sense advice may sound easy enough to follow. Yet in the real world of round-the-clock, high-cycle manufacturing operations, bearings do get dirty and dry. And when either of these conditions happens, linear bearings will wear prematurely. In the worst-case scenarios, contamination and inadequate lubrication can create metal-on-metal contact between the bearing’s rolling elements and raceway. This can cause excessive wear in the form of denting, pitting, or galling results.

Hull-Cleaning Robot for Large Ships

Toxic paint is used on the bottoms of large ships to prevent fouling, which is when a biofilm layer develops, decreasing the ship’s efficiency moving through the water. To further complicate the matter, the paint must be blasted off and replaced every 5 to 10 years, at which time literally tons of toxic waste is produced and needs to be disposed of.

High-Accuracy Closed Loop Force Feedback

Benefits of serial servo digital presses for force gauge specifications. Hand-driven press assemblies, which require a specific amount of force applied for a given amount of time, present challenges when attempting to accurately measure or replicate results in production or quality control processes. In contrast, servo-driven digital presses are able to provide accurate, consistent, and repeatable results while outputting trackable data. By controlling position and current, the servo-driven digital press allows for stable, accurate, and repeatable control.

Rotary Sensing Technologies for Medical and Robotic Shaft Angle Sensing Applications

This technical brief provides an overview of existing types of rotary sensor technologies, and compares the strengths and weaknesses of each type for use as through-hole shaft angle sensing devices. Today’s sensor technologies for robotic and medical applications include many devices that have evolved from industrial applications. Because of this general migration, they are not ideally suited to the requirements in new robotic and medical products. Specifically, conventional contacting and non-contacting sensing solutions do not offer the customization, small package size(s), and environmental and durability requirements that are so necessary in these custom applications.

Optimized Machine Capability Through Mechatronics: Packaging for the Future

Mechatronics can be defined as the science to optimize the performance and capabilities of machines using a multi-domain synergistic design approach. It is also described as the combination of mechanical, electronic, computer, software, control, and systems de - sign engineering. Simply put, this concept enables machine builders to produce machines that produce the highest quality at maximum throughput. Additionally, it empowers manufacturers to make incremental improvements to existing assets to ultimately meet or exceed core key performance indicator (KPI) targets.
