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.
