摘要: Owing to some excellent properties (such as large transmission ratio, high reliability, high precision, large sti?ness, small volume and long service life), ˉltering reducers are suitable for occasions with high require- ments (e.g. space equipment). However, the tough working condition in space (including frequent changes of temperature, and large temperature di?erence combined with shock loads) may signiˉcantly a?ect the reliability. In this paper, the expressions of the minimal and maximal instantaneous transmission ratios (ITRs) considering temperature correction are developed. The minimal and maximal ITRs from simulation are used to verify the accuracy. Moreover, the reliability of a ˉltering reducer under di?erent temperatures and the shock load are calculated, respectively. The research is beneˉcial to the design of spacecraft mechanism.
