Abstract
The gear mesh stiffness, and therefore the load sharing, tooth deflections, and transmission error, are strongly influenced by the tooth dimensions and profile shape. But the profile shape and contact conditions are affected by the wear produced by the relative sliding of the teeth surfaces, so that load sharing and transmission error change as the wear depth increases. Consequently, the wear depth increase is different at any contact point—because the load and sliding velocity are different—and in any meshing cycle as well—because the load sharing changes with the accumulated wear—. In addition, the length, depth, and shape of profile modifications may sensibly affect the initial load sharing, and therefore the complete wear process. In this paper, a model of meshing stiffness, load sharing, and transmission error for spur gears with profile modifications including the influence of wear is presented.
