Results are presented from a redesigned powder metal transmission that has been tested for durability, vibration, overload, and breaking load.
In this article Hoganas demonstrates some design aspects that can—and need to—be considered when working with powder metal gears.
The author focuses on material characteristics and the effects of porosity on powder metal gear technology.
This second article in a series will touch on Noise Vibration and Harshness (NVH) specifics related to Powder Metal (PM) gears.
This third article on Powder Metal (PM) gear technology discusses micro design of the gear flanks to maximize robustness of the gears.
Better flow for cooling media, weight and error reduction, and root optimization are all beneficial results for using powder metal gears.
Densification technologies in powder meal gears: If pores are eliminated where high stress occurs, gear performance will improve.
Another unanswered question with this technology is: What happens to the pores? Are they flattened into cracks after the process? There are hypotheses about cold welding and healing in heat treatment of the flattened pores, but none have been proven.
In this sixth article, manufacturing of PM gears will be discussed, along with different cost scenarios.
Reduce investment costs for a new gear factory by going the PM route.
In this final—Materials Matter—column on Powder Metal Gears, some new tests that we have conducted will be presented, and some loose ends from past columns are tied up.
Price and the ability to offer a much larger design window are making manufacturers look to powder metal gears as a solution for high-performance gears.
