Profile corrections on gears are a commonly used method toreduce transmission error, contact shock, and scoring risk. Thereare different types of profile corrections. It is a known fact,that the type of profile correction used will have a stronginfluence on the resulting transmission error. The degree of thisinfluence may be determined by calculating tooth loading duringmesh. The current method for this calculation is very complicatedand time consuming; however, a new approach has been developedwhich could reduce the calculation time.
This approach uses an algorithm which includes the conventionalmethod for calculating tooth stiffness in regards to bending andshearing deformation, flattening due to Hertzian pressure, andtilting of the tooth in the gear body. The new method was tested bycomparing its results with FEM and LVR.
This paper illustrates and discusses the results of this study.Furthermore the maximum local power losses are compared with thescoring safety calculated following the flash temperature criteriaof AGMA925 and DIN 3990.
