Grp27: Piston Bearing
Material: Cast Aluminum
Manufacturing Process: This part was made by casting. The best guess of the type of casting is consumable pattern casting.
Function: Holds piston assembly to crankshaft.
Pressed off of crankshaft journals.
Aluminum was used because it was light weight, and would not apply a lot more load onto the crankshaft.
Force that holds the bearing to the lobe is applied.
Force that holds the bearing to the lobe is estimated at 10 lbs.
The material choice does not effect the process. This part was cast so any other type of metal that could have been used would have probably been cast as well.
The shape does not effect the manufacturing process either. It is just cast so its shape would be processed the same no matter what.
This components shape is mostly a circle. This is to fit the lobe it is usually stationed on.
This component is functional. It is just cast, and no other process that would hint cosmetic is used to make this component.
The processes for this component was chosen because they were the most cost effective and most likely least time consuming.
On a scale from 1-5, 1 being the simple like a ball, and 5 being complex like a engine, this component is a 1. This component is a simple attachment that connects two vital components in the whole system together.
