Abstract
The size of planetary gears in heavy truck gearboxes means that PM can be a cost effective alternative to conventional manufacturing from forged blanks. Warm compaction and surface densification offer effective routes to reach high density, and thereby high strength and fatigue properties. Characteristics for PM gears manufactured by these methods are outlined and compared with wrought and machined gears.
