| Summary: | This thesis is an approach to investigate the transformation curve of gearing
safety. Two types of tooth failures are known to happen to spur gears. There are
tooth bending failure (breakage) and tooth surface pitting failure. The focus of this
study however will be on the JGMA and AGMA standards of gearing. Different
methods were used to gather relevant data from both standards. JGMA data were
gathered from a source in the internet while AGMA data were calculated with the aid
of Autodesk Inventor spur gear component generator 2013. The most important data
is the allowable torque applied on the gear tooth which can be distinguished into
causing either one of the tooth failures mentioned above. Several materials selected
from the JGMA and AGMA standards with high value of allowable contact stress
compared to its allowable bending stress have a transformation curve from surface
durability to bending strength when its torque values are plotted against number of
teeth. This allows the forming of a combination threats curve for the material. The
curves are useful in determining the maximum torque that can be applied on the spur
gear before failures occur. The threat combination curves are then further developed
into charts that include other parameters like power, angular velocity and pitch
diameters. |
