Stress Analysis
There are two basic modes of potential failure for keys transmitting power:
1. shear across the shaft/hub interface
2. Compression failure due to the bearing action between the sides of
the key and the shaft or hub material.
Figure shows the idealized case in which the torque on the shaft creates a
force on the left side of the key.
