Pushing Forward with Belts and Chains
The technology continues to evolve in chain- and belt-driven systems

A Mechanical Healthcare Plan
Motor Operation Gets Big Boost from Smart Technology (Here's How to Take Advantage)

Simulation Software Provides a Different Set of Tools for Motor Efficiency
While some organizations focus on real-world analytics and data collection for predictive maintenance, simulation tools and virtual prototyping can be another solution for motor efficiency.

Custom Machine and Tool Bolsters Accuracy and Efficiency for Vande Berg Scales
If you can find that magic bullet that will reduce the machining process, you can achieve meaningful efficiency gains. It is imperative that check-weighers or in-motion weighing systems remain both accurate and efficient while attaining a consistently smooth operation because they dynamically weigh products as they move across the belt.

Machine Parts No Longer in Production
Good machinery can last a lifetime. But, replacement parts for older equipment may be near impossible to find. So, what do you do when you're looking to replace hard-to-find bearings and related parts for older machines?

Keeping the Lights on - Machine Monitoring Basics
As manufacturers continually search for ways to cut costs and increase ROI, machine monitoring and predictive maintenance (PdM) solutions are an increasingly cost-effective way for plants and factories to help reduce process downtime.

Finite Element Method Based Analysis of Planetary Gear Systems Considering Backlash and Manufacturing Deviations
The load carrying capacity of gear transmissions depends strongly on design, material and operation conditions. Modern analysis methods, e.g. finite element analysis (FEA), consider the above parameters with more or less sufficient accuracy. Yet it remains an ongoing challenge to account for backlash and manufacturing errors, despite a definite need to do so.

Thrust Cone Bearings Provide Increased Efficiency for Helical Gear Units at Moderate Speed Levels
Thrust cone bearings are an elegant option to handle the axial forces generated by the torque transmission in helical-toothed gear stages. They have proven as an efficient and reliable bearing concept for integrally geared compressors but are nearly unknown in other fields of gearbox engineering. The presented investigations consider three aspects which appear relevant to extend the field of possible applications for thrust cones towards gearboxes constructed with roller bearings.

Choose the Form (Publishers Page)
In the 1984 film Ghostbusters, Bill Murray and company were asked by Gozer the Gozerian to "choose the form" of their destructor. It was a no-win scenario for the heroes, because no matter what they chose, they were still going to face death

The Gizmo Society (Voices)
It is hard these days to find any device that is not IoT-compatible or WiFi-connected. I recently had a new well pump installed that requires an iPhone for setup, which makes it hard for me to check or change the setup since I do not own an iPhone. In Olden Times, you had potentiometers or RS-232 connections - and that was fine.
