A kind of precision harmonic gear drive in the focusing mechanism of space camera is studied  which adopt external meshing complex wave transmission mode. Wave generator is combined with an elliptic cam and a flexible bearing around it. Flexspline is a structure of single wave with the same teeth. The output shaft is supported by a single cross-roller bearing. Ball screws connected the output shaft translate the rotational motion to the linear motion  and drive the focusing mirror repeated moving along the linear guide. The output rigid wheel is connected with absolute encoder to detect displacement of focusing movement. It has the characteristics of big transmission ratio  high precision  compact structure  high efficiency and smooth running etc. According to the practical application of this harmonic gear drive in the space camera  the location relationship between the displacement of focusing structure and the focal plane movement is derived  and the system error is analyzed  its accuracy is tested with the open-loop control method. Experimental results show that transmission ratio of the instrument is 1:70  repeated positional accuracy is 2m  which meet the requirements for use. 2010 SPIE.
