Abstract(E)	In this paper, the fatigue strength of the roller chain is investigated by varying the press-fitting ratio between the pin and the plate. A single plate specimen with two pins press-fitted into two holes at the plate ends is used in the fatigue test. The FEM analysis is performed to obtain the stress amplitude and the average stress on the fatigue endurance limit diagram. The results show that the fatigue strength can be improved under suitable press-fitting ratios δ/D=2.5×10-3, 5.1×10-3, 9.5×10-3 compared to the fatigue strength under press-fitting ratio δ/D=0.

About search

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
