The Real Truth Behind Cpk and Ppk Capability and Potential Process Studies
The most common definition of Cpk and Ppk is this: Cpk is the short-term capability of a process, and Ppk […]
The Real Truth Behind Cpk and Ppk Capability and Potential Process Studies
These are very good questions. This paper will describe what you really need to know about estimating the true potential […]
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 […]
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 […]
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
