Thin Rims for Internal Gears
In today’s applications it is increasingly important to use space and resource-saving gears. One possibility is to design the rim […]
Alternatives to Gear Grinding
Stringent NVH requirements, higher loads, and the trend toward miniaturization to save weight and space are forcing transmission gear designers […]
Refurbishing Wind Turbine Gears
Multi-megawatt wind turbine gearboxes operate under demanding environmental conditions including considerable variation in temperature, wind speed, and air quality. It […]
Reducing Gear Rattle
Work trucks are getting quieter, driving the need for axillary power to do the same. While gear noise, whine, and […]
Increasing Efficiency with Synchronized Systems
Every manufacturer is faced with the decision at some point: is it time to upgrade equipment and expand my capabilities? […]
Recommendations for Reverse Engineering
Reverse engineering is a necessary activity in the modern industrial world. Rather than mount a defense against those who label […]
Take a PEEK at Polymer
Much has been written about PEEK polymer’s ability to withstand extreme temperature environments and other key properties including strength and […]
Troubleshooting Gear Noise
NVH engineers are used to measuring things. Any NVH—for “noise, vibration, harshness”—lab you visit will likely as not be stuffed […]
A Solution for Gear Bore Accuracy
Did you hear about the amazing new technology that enables gear makers to achieve bore accuracies measured in ten-millionths and […]
