Create a solid part model and an associated A3 detail drawing of a spur pinion gear shaft with a square drive end and a center hole. Work in millimetres. Name the part file creo-ex-13.prt and the drawing creo-ex-13.drw.

The shaft is a single turned part, 92 long overall, built on one axis. From the left end:

  • Journal: Ø15, 13 long.
  • Hub: Ø23, 14 long.
  • Spur gear: 40 outside diameter, 31 root diameter, 15 face width. C1 chamfers on the tooth edges.
  • Second hub: Ø23. The span from the start of the first hub to the end of this hub is 47.
  • Right shaft: Ø15 to the right end. C1.5 chamfer at the end face.

Add an R3 fillet where each hub meets the gear root. Cut a square drive on the last 16 of the right end, 12 across the flats, with a 2 dimension at the start of the flats. Add a 60° center hole to KS B 0410, type A, size 2, in the right end face.

Model the gear teeth evenly spaced around the shaft axis on a Ø36 pitch circle. Size the tooth form with these values:

  • A tooth tip width of 1.2.
  • R10 flank arcs.
  • A separate dimension of 4 at the tooth.

Produce a drawing of the part on an A3 sheet with these views:

  • A front view with the axial dimensions 13, 14, 15, 47, 16 and 92, the diameters 15, 23, 40, 23 and 15, and the 2 dimension at the square drive.
  • A full longitudinal section view, hatched, showing the 31 root diameter, R3 and C1.5.
  • An end view showing the tooth form (R10, 4 and 1.2) and the 12 square across flats.
  • An isometric shaded view.

Annotate C1 on the gear and add the center hole note "KS B 0410 60° A 2,".

Create a solid part model and an associated A3 detail drawing of a spur pinion gear shaft with a square drive end and a center hole.

Created and refined a Creo Parametric shaft-and-gear part with revolved, extruded, chamfered, patterned, rounded, mirrored, and hole features. Saved the part, produced an annotated engineering drawing with multiple views and sections, and exported the drawing as a PDF.
