A simplified model for calculating deformation of a gear tooth is proposed. In this model, the gear tooth is expressed by many thin gears that appear at the sections perpendicular to the tooth helix. Each thin gear deforms as a cantilever by the tooth load, and load transmission between the thin gears is made by shearing. Therefore, the tooth deformation that generally falls into a three-dimensional problem can be calculated as a two-dimensional problem. Using the proposed model, the transmission errors and tooth contact patterns of the spur gear pairs under the loaded conditions are analyzed in consideration with interference between the tooth tip and the mating tooth root. To confirm the calculated results, the loaded meshing tests were conducted on the gear-testing machine. The test results gave good agreement with the calculated ones.
