Tooth geometry
Specify module or diametral pitch, tooth count, pressure angle and face width. For helical teeth, include the helix angle and hand. Provide bore or shaft references and any specified profile modification so tooth geometry can be reviewed with the gear blank.
Material & hardness
Include the material designation, blank condition, heat-treatment requirements and hardness. Show the bores, journals and faces that locate the gear in its assembly. These details help us discuss the relationship between turning, hobbing and any specified finishing operations.
Gear acceptance
State the gear accuracy standard and grade specified by your design, along with tooth inspection requirements and requested reports. Include mating gear information when relevant. Tooling, geometry and acceptance criteria are reviewed before a manufacturing commitment is made.
Manufacturing feasibility, tolerances and inspection requirements are reviewed for the individual project.
