The outer rotor has the trend of revolution along the inner rotor and this trend must be overcome by the cylinder via the action of a support force in an internal-meshing rotary cycloid compressor. The position of the support force was analyzed with certain simplification by applying tolerance or clearance of all meshing surfaces. The result shows that the direction and position of the support are only determined by the geometric relationship instead of the gas force and contact force. It is suggested that the position of the support force should be firstly obtained before the calculation of the support force and contact force.
