A gear inspection system and method for a gearbox, wherein an image acquisition unit is oriented proximate the gearbox with a field of view of a section of the gears. The image acquisition unit obtains images of a gear tooth and corresponding contact pattern. In one embodiment a processing unit transforms the images to a gear tooth model so that the gear tooth image and contact pattern image matches the model gear tooth. Metrics are computed for the contact pattern, and based on threshold values, a determination is made as to whether the gearbox is acceptable.

Method and system for estimating contact patterns

A method of computing gear modifications from a gear inspection chart is provided. The method includes extracting a gear profile from the gear inspection chart. The method also includes quantifying the gear profile. The method also includes determining a gear modification based on a quantified gear profile. The method also includes qualifying a gear based on the gear modification.
