Calculating Inverse of Involute Angle in Microsoft Excel Without Programming
A lot has been written and discussed about how to calculate the inverse of involute angle in technological magazines and […]
The Surgeon and the Gear Maker
Delta Gear bought TIFCO Gage & Gear, a maker of master gears, spline gages, aerospace gears, and automotive prototype gears […]
Epicyclic Load Sharing Map-Application As a Design Tool
One of the main advantages of planetary transmissions is that the input torque is split into a number of parallel […]
An Algorithm for Robust Gear Modifications Design
The design of gear modifications is one of the key tasks for high performance gears, where high performance may be […]
Understanding and Preventing Surface Distress
In many industrial applications that have lubricated rolling/sliding contacts such as rolling bearings, power density has steadily increased over time […]
Applications for Self-Locking Gears
In most gear drives, when driving torque is suddenly reduced as a result of power off, torsional vibration, power outage, […]
Helix Angle and Root Stress
The ISO and AGMA Gear Rating Committees have for several years been comparing the results of different rating methods for […]
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 […]
Designing Asymmetric Gears
In propulsion gear transmissions, the tooth load on one flank is significantly higher and is applied for longer periods of […]
Reducing Gear Rattle
Work trucks are getting quieter, driving the need for axillary power to do the same. While gear noise, whine, 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 […]
Powder Metal Gear Conversion
There are many different processes performed in the “powder metal” arena. They range from conventional compacting with sponge iron (low-density, […]
Black Oxide Finishing for Gears
