Modification Analysis of the New Axis-Fixed Cycloid Drive


Article Preview

Due to those disadvantages of the cycloidal-pin wheel transmission, such as complex structure, low efficiency and low bearing capacity, a new kind of axis-fixed cycloid transmission is proposed. A new method for optimum modification quantity of cycloid gear is put forward on the ground of its drive principle. Considering the influence of modification to tooth contact stress, finite element model of tooth contact for the drive is built.The analysis result indicates that there is no obvious edge contact of tooth profile and it is more reasonable for the contact stress to distribute along tooth width. Load test on gear drive bench verifies the correctness of theoretical analysis.
