Abstract(J)トラクションドライブ式CVTにおいて高い伝達効率を実現するには,高精度に最大トラクション係数を推定する必要があり,そのためには油膜内の温度推定が重要となる。そこで,モデル試験機において薄膜温度センサによりトラクション接触部の温度解析を行った。

Translation

Abstract(E)High accuracy estimation of maximum traction coefficient is required to achieve high transmission efficiency at toroidal traction-drive continuously variable transmission. Temperature of oil film at transaction contact area is important factor because of its effect on maximum traction coefficient. Thermal analysis of this area was performed by using thin-film temperature sensor in the condition of model evaluation. The thin-film sensor has a feature of high specific pressure capacity and quick response. As a result, measured temperature gave close agreement with calculated value.

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.
