Deep-Tooth Pinion Gear

Central Feature (Annotated '4''-0' in image_1.png): A precision, central cylindrical passage (the shaft hole) with a diameter of exactly 4.0 units. Hub Detail: Surrounding the central hole, create an integrated hub. Key Dimension 3 (Annotated '4''-0' in image_1.png - assumed intended for pinion): The Outside Diameter of the pinion teeth (tip-to-tip) must be approximately 46.0 units, creating a specific center distance. The '4''-0' mark in image_1.png seems to indicate this overall scale for the pinion relative to the 120'' ring, or perhaps a central boss on the hub. Interpreting it as a central hub diameter of 46.0 fits the geometry. Let's make it the Pinion Outside Diameter (tip-to-tip) = 46.0 units. New Tooth Depth Constraint: The depth of the external pinion teeth, measured from the tip to the root, must be exactly 12.0 units. Pinion Details: Retain the concentric pitch circles and base circle diameter indicators. Engrave the text: 'Base circle diameter', 'Pitch diameter', and 'Outside diameter'. Motion Arrow: Retain the inner counter-clockwise motion arrow and the clockwise outer arrows on the pinion.
