Abstract:Tolerance analysis of a planetary reducer is conducted. By focusing the serially-arrangedparts in the central line and setting an appropriate dimension as a "gap", worst-case tolerance analysismethod and statistical (RSS) tolerance analysis are used, and then a tolerance-analyzing tool CE/TOLis introduced. The acceptable value range of the "gap" is from 1.5 mm to 3.5 mm. While worst-caseanalysis 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 areassigned and modified, and more detailed and more comprehensible results are gives out.
Keywords:Tolerance Worst-case analysis Statistical tolerance analysis Pro/E CE/TOL
