【Abstract】 After comparing the merits and shortcomings of existing anti rotation mechanisms in scroll compressors made at home and abroad, a new planetary anti rotational mechanism with homodyne of tooth number is presented, its structural parameters are determined, and its strength is also prooftested. Major advantages of this mechanism are its simple configuration, smaller axial dimension, rolling contact at meshing point of gear transmission, and high transmission efficiency and accuracy.更多还原
