Tolerance analysis of a planetary reducer is conducted. By focusing the serially-arranged parts in the central line and setting an appropriate dimension as a gap, worst-case tolerance analysis method and statistical (RSS) tolerance analysis are used, and then a tolerance-analyzing tool CE/TOL is introduced. The acceptable value range of the gap is from 1.5 mm to 3.5 mm. While worst-case analysis rejects the design, RSS accepts it by a more realistic result with the law of probability accounted. With the help of CE/TOL and CAD software Pro/E, all components' dimensions and tolerances are assigned and modified, and more detailed and more comprehensible results are gives out.
