Modeling Study To Tooth Surface Modification Of Shaving Cutter

Gear shaving is one of gear finishing operations, which is widely used for most gear-making factories because of its high efficiency and low cost. However, after shaved by shaving cutter with true involute profiles, there are the "mid-concave" phenomena on the pitch points of shaved gear tooth profiles inevitably. Gears shaved like this will not only influence gears transmission accuracy, but also generate much more noise while running, and shorten greatly the operating life of the gears. At present, although much has been achieved on the research of mechanics of shaving process, there is not much quantitative description about the weight of each error-generating factor to the generation of mid-concave error due to the complexity of shaving process. So it is necessary to study the shaving principle and take effective measurements to solve it. The dissertation makes studies on tooth surface modification of shaving cutter based on present state and...
