Abstract(J)加速時噛み合い騒音の原因究明のため、ギヤ回転変動解析手法であるヒルベルト変換法に対し、回転信号をトリガーとして加え、高精度なトランジェント計測を可能とした。本計測を用い、加速時騒音の原因がギヤ伝達トルクに起因するギヤ変形による噛み合い状態悪化であることを明らかにした。

Abstract(E)The authors develop a new measurement method for the rotational movement of gear under transient state. Transient state signals of gap-sensor which detected movement of gear teeth were transformed to quasi-steady state signals using trigger pulse which was gotten per revolution, and then analyzed with Hilbert Transform. It became clear that the gear noise during acceleration of gear rotational speed is generated by worsening gear meshing-performance due to elastic deformation of gear teeth caused by gear transfer torque.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
