Abstract

On the basis of the research and analysis of measuring principle of the gear accumulate pitch, it was concluded: spacing-tooth relative method was applied for the large gear whose diameter was over 2.5m, to measure its accumulate pitch error so that measuring error was reduced, its measuring precision was improved. For the characteristics of gear's inertia in measuring process, on-machine measuring instrument of gear's total accumulative pitch error on large hobbing machine was designed. The origin and compensation method of the measuring system error were analyzed and studied, which determined the formation cause and affect law measurement error resulted from comprehensive geometric eccentricity of measured gear installation, a rational error compensation method was proposed, which made measurement accuracy further improve.
