Objective

Create a gearbox plate for a shifting gearbox from a drawing.

How-To

If None Of this Makes Sense, Watch the Videos Before for a Demonstration of How To Model the Shaft.

• Download drawing from "Files" section below.
• Create a sketch and start sketching the various holes, usting the main output shaft bearing bore as the center of the part, placing it at the origin.
• Add the other bearing bore.
• Add one set of motor mount holes and mirror it to the other side.
• Add the various mounting holes and mirror as appropriate.
• Sketch the outside profile of the plate and add concentric and tangent relations.
• Extrude to the depth listed on the drawing under the "materials" section.
• Add the two counterbores.

• Gearbox Plate Drawing
• Gearbox Plate SolidWorks Part File

Correction: On the drawing, the counterbore depth is shown as .62". The actual value is .062". It is correct in the part file.
