Abstract

Involute gears have been developed for a long time and already used in many applications. In addition, special tooth profile, such as cycloid, are used in special gearing. To facilitate rapid gear design and load analysis, loaded tooth contact analysis (LTCA) approaches have become essential and efficient tools. In this paper, the results of involute gear pair computed by two models: RIKOR developed by FZG at TUM and LTCA model developed by MDL at NCU are compared. The variation of contact stresses under four different conditions, such as without modification, with flank crowning, with profile crowing and with double crowning are also concerned. Furthermore, the LTCA model is extensively applied to analyse a new type of gear known as EC gear. Unlike involute gears, the contact points of EC gears form a spatial curve. The model utilizes discrete grids distributed on a ruled surface, which is constructed using a set of contact points and their tangent vectors. The accuracy of the simulation results is validated by comparing the results calculated by ANSYS.
