| Summary: | An approach of analysis of static load sharing based on meshing characteristics for straight bevel gears split transmission is proposed to improve meshing performances. The initial contact clearances of each gears pairs are obtained through establishing the tooth contact analysis method for multi-gear （MTCA） by considering alignment error of the center gear. A statics balance equation considering the coupling of support deformations and torsion deformations of each gear pairs and the meshing deviation caused by the initial contact clearances are established to study the floating characteristics of the center gear based on lumped-parameter analytical model. The static load sharing coefficient of each split is obtained by solving the equation， and the influences of loads， alignment errors and support stiffness on it are analyzed. The results show that static load sharing coefficient increases gradually with the increase of both support stiffness and the alignment errors， the influences of axial and bias alignment error on it are the same level. The load sharing coefficient decreases with the increase of torques. The magnitude of transmission errors represent the variation law that the larger the initial clearances of the tooth， the smaller the load sharing coefficient. It provides a theoretical reference to analysis load sharing for high precision straight bevel gears split system. |
