Radial Engine Assembly : Week 4 Challenge

Procedures

Piston: -

One side of the drawing given in section view A-A was drawn first and then revolved around the vertical axis to get the main piston body shape.
Then created a plane at a distance of 25mm and made two circles on this plane and extruded it by 21.5 mm.
Then created a pocket in this new cylinder as shown in the sketches
The common edge between the main body and this new hollow cylinder was extracted using extract command in generative shape design workbench
then extruded this edge up to some length and then thickened it using the thick surface command in part design workbench in a new body.
Then removed this body from the main body using the boolean remove command.
Did the same thing on the opposite side.

---> Bush upper, Bush lower, Master rod bearing, piston ring, piston pin plug, and link pin were made by drawing the sketch and padding it.

Master Rod: -

The large hollow hole was made first and then at a 28 mm distance, the sketch was created and then extruded.
Then this whole part was mirrored with respect to its base plane
Sketch as shown in Section view B-B was drawn and padded.
Then created the hollow cylinder present on the other side
Then rectangular slot was created
Finally attained the draft angle for the connecting rod by making a triangular sketch and then pocketing it.

Articulate rod:-

Padded the rectangle and then gave the rectangular slot on both sides
then hollow cylinders were created on both the ends and gave the required fillet size and given locations.

Assembly: -

First made the sub-assembly with Piston, Piston ring, Upper Bush, Piston Pin, Rod bush lower, Articulate rod, Piston pin plug to ease the final assembly.

Next made the subassembly of piston with piston rings to reduce the cumbersome in the final assembly
