Powder Metal Gear Design

Instead the direct gear design method ref 2 is better suited where the functionality of the gear dictates geometry.
Powder metal gear design. The powder metallurgy gear was compacted using mo prealloyed steel powder 0 85 wt mo mixed with 0 3 wt graphite and lubricant. Two major factors in the compacting operation influence design considerations with powder metallurgy. Powder metal gears can help you reach your cost reduction goals without sacrificing quality and strength. 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.
The flow behavior of metal powders and the pressing action. Pmg is your partner when it comes to the design testing validation series production and stock management of cost effective powder metal gear solutions. 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. For more information look elsewhere on this website by choosing the.
Here are some reasons why it s gaining increased acceptance plus some ongoing advancements. Powdered metal gears are made through the process of powder metallurgy. Parts were compacted at 7 2 g cm3 sintered at conventional temperature 1120 Âșc on a belt furnace and surface densified at a minimum core density of 7 30 g cm3. Powdered metal gears are used in many industries but are used most in the automotive sector.
Pm gear design powder metal manufacturing technology offers and de mands a different design approach. Powder metallurgy is a proven technology to produce high strength gears for the automotive industry. 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. Metal powders do not flow hydraulically because of the friction between particles and the dies.
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. 7 powder metal gear design and inspection september october 1996 powder metallurgy p m is a precision metal forming technology for the manufacture of parts to net or near net shape and it is particularly well suited to the production of gears. Conventionally cut gears are based on rack generation but pm gears are not limited by that. Spur bevel and helical gears all may be made by made by powder metallurgy processing.
