Introduction
This is report about the design of machining process for a classical aeroengine part i.e., a lubricating oil pump shell. Proper lubrication is critical
to successful engine operation. Lubricating oil pumps are used to supply oil to lubrication points, e.g., for plain bearings. In the case of circulation
lubrication, the lubricating oil pump takes in an amount of oil from a reservoir, forces it through the lubrication points and then feeds it back to
the reservoir. The lubricating oil with a certain pressure will be continuously sent to the friction surface. For example, the oil film is formed at
main crankshaft bearing, connecting rod bearing and camshaft bearing, rocker arm and so on to ensure lubrication. The target part to be
designed is the pump shell of an external gear pump.
Pump shell
Design Content Description
2D Part Drawing
SolidWorks 2022 was used to create, iterate, and analyze the design of the pump shell prior to manufacturing. The design was scaled to the
actual dimensions. To accomplish this the SolidWorks 2022 used parametric modeling. After entering the SolidWorks workspace for a new part,
the preparation of a sketching plane was initiated. As mentioned before, SolidWorks uses parametric modeling. This means that parameters
were assigned to entities like lines and features of the sketch. As a result, it was necessary to assign the dimensions while the sketch was being
created. Afterwards the geometry of the sketch was refined. More dimensions were added to the sketch. The last step was to do the centering
and alignment of the drawing. Finally, the fully dimensioned 2D sketch had been created parameterizing the outline of the pump shell.

For making the 2D drawing, the 3D model of the target part (pump shell) was used.
The sheet format was selected and the drawing views from the view palettes were applied.
Manual dimensions, cross section views, detailed views, 3 standard views, dimensions with tolerances, basic, bilateral, symmetric,
geometric tolerances etc. were all applied.
Machining symbols and text were applied.
After creating the drawing, the sheet format was edited, applying material name, drawing name, title block, name of the student etc.
