HOW TO PREDICT THE TOOTH ROOT STRESS OF A CROWNED GEAR

Traction gears of railcars and locomotives are affected by alignment error between gear shafts, rigidity of gear case, etc. For this reason, such gears of JNR are relieved and/or crowned at the tooth face in order to avoid a local high tooth bearing, which leads to a failure. The conventional calculation methods of the crowned gears are tedious and troublesome. A simple method is proposed which utilizes a table of figures, that is good for practical application.
