Engagement of Metal Debris into Gear Mesh - September/October 2010
The article "Engagement of Metal Debris into Gear Mesh" appeared in the September/October 2010 issue of Gear Technology.
A series of bench-top experiments was conducted to determine the effects of metallic debris being dragged through meshing gear teeth. A test rig that is typically used to conduct contact fatigue experiments was used for these tests. Several sizes of drill material, shim stock and pieces of gear teeth were introduced and then driven through the meshing region. The level of torque required to drive the ‚¬Äœchip‚¬Ä¬Ě through the gear mesh was measured. From the data gathered, chip size sufficient to jam the mechanism can be determined.
