Abstract
The load bearing capacity of surface-rolled sintered metal gears were investigated. Sintered metal gears were made using hobs with different tooth profiles and surface-rolled to different degrees using two different rolling machines and heat-treated. The effect of surface-rolling on surface properties were examined by measuring porosity and hardness near rolled gear teeth surfaces. Run tests for test gears were conducted. The effects of surface-rolling on the load bearing capacity of sintered metal gears were determined, and the results were compared to the results for wrought steel gears.
