The closed differential planetary gear train transmits power in multiple paths, which has large power transmission and compact structure. It is widely used in high-power occasions such as ships. However, the closed differential planetary gear train has many power flow paths and complex structure. If the structural design is unreasonable, there will be power cycle (closed power) in the system, which will seriously reduce the efficiency of the system. There are many components of closed differential planetary gear train, and the uniform distribution of load is of great significance to improve the transmission quality and service life of the system.This paper mainly summarizes the research status of ordinary planetary gears, the power flow analysis status of closed differential planetary gear transmission and the efficiency analysis status of planetary gear transmission.
