Powder Metal Helical Gears

Densiform helical powder metal gears for automotive transmissions.

Powder metal helical gears. Eliminates secondary operations such as hobbing shaving and grinding. In addition to complexity in compaction and the difficulties to achieve high core density pm gear blanks require deep surface densification to maximize strength along the root fillet and on. Results in a powder metal gear with similar rolling contact fatigue properties to wrought and forged gears. Produces a mirror surface finish to reduce nvh levels.

Spur gears helical gears cluster gears pinion gears planetary gears fine pitch gears. There have been many advances to this process over the years which have in turn caused an increase in the popularity of powdered metal as a gear material. Our engineering can help you with a smooth changeover from your current higher cost method of manufacturing gears to a high quality powder metal gear with annual quantities possible of 2 500 5 000 or to 500 000. Has the ability to crown the gear tooth profile for improved load distribution and minimize noise levels.

Powdered metal gears are made through the process of powder metallurgy. Powdered metal gears from keystone combine state of the art design fully integrated production and extensive testing to set the standard for precision strength and quality. Pmg is your partner when it comes to the design testing validation series production and stock management of cost effective powder metal gear solutions. However helical gears are more difficult to produce to these same densities because the geometry does not lend itself to the dp ds process.

By having redesigned and prototyped different gears off production tooling to optimised powder metal gear designs pmgi has demonstrated the functionality and the full potential of stress weight. Whether you need to decrease the weight and noise of your gears increase core and surface strength or eliminate a failure condition our engineers can offer the solution. Advances in powder production compaction and sintering combined with double pressing have enabled overall part densities up to 7 5 g cm in spur gears.

Powder metal gears can help you reach your cost reduction goals without sacrificing quality and strength. A major step forward in automotive helical gear production by powder metallurgy was presented in a paper at pm2012 world congress in yokohama by dr salvator nigarura director of research and development at pmg corporation and colleagues in columbus in usa.
