This 3D model was created by SOLIDWORKS2022Other formats includeX.TIGSSTPThis is a simple planetary gear mechanism. Mainly composed of sun gear, ring gear, planetary gears, etc., these components are arranged in a specific way to jointly achieve power transmission and speed change functions. In planetary gear mechanisms, the sun gear and ring gear share a fixed axis. Planetary gears can rotate on their own while revolving around the sun gear. Planetary gear mechanisms can be classified into various types based on their structure and application scenarios, such as Simpson planetary gear mechanisms, Lavina planetary gear mechanisms, etc. These institutions are widely used in fields such as automatic transmissions and agricultural machinery.
