説明

Specifying the origins of ghost noises produced at non-integral multiples of gear meshing orders from the order at which they occur represents a challenge, and determining countermeasures for these noises has involved a process of trial and error. Today, with the widespread use of a method of continuous generation involving the use of a multiple-thread-type tool for high production efficiency in the process of grinding the flanks of the helical gears used in automotive transmissios, new ghost noises have appeared. The research discussed in this paper clarified the mechanism behind the production of the ghot noises that have become noticeable as a result of the use of the multiple-thread-type tool, and identified the relationship between the orders at which the noises occur, the level of undulation on lead form that cause ghost noise and the conditions used in the grinding process. Then the project verified these findings in an actual transmission.
