Woodruff key performance weakness

Woodruff key performance weakness

Woodruff key is a key, which has a planar upper surface, a lower surface of a semi-circular arc, parallel to the side surfaces, commonly known crescent key. It links with the flat key is basically the same way, but relatively easy to manufacture flat key, easy disassembly, especially for tapered shaft and coupling hub. The disadvantage is that weakened the strength of the shaft, generally only in small parts used force.

Woodruff key connection strength calculation

Just know that the shaft diameter d, check the manual machinery can get all the Woodruff key dimensions include nominal length, including
