Influence of Module and Pressure Angle on Contact Stresses in Spur Gears

Abstract—Contact stress between meshing gear teeth depends upon the material pair, normal load and the teeth geometry. Normal load at different points of contact changes during contact period, which depends upon the contact ratio. For identical material and operating conditions, contact ratio and the teeth geometry depends upon module and pressure angle of the gear pair. In the present work contact stress and contact fatigue analysis of spur gears has been carried out for identical operating conditions, for different values of module and pressure angle. Results of the investigation indicate decrease in contact fatigue life with increase in module as well as pressure angle.
 
Index Terms—spur gear, contact stress, involute geometry, module, pressure angle
