Engineering Drawings
Manufacturing-style drawings for the assembly and each individual component, with dimensions, threaded features, section views, and material specifications.
Overview
Designed a compact shaft-seal assembly for a small fluid-handling system, addressing the challenge of allowing a rotating shaft to pass through a housing while minimizing leakage. I modeled a flanged housing, packing nut, and lock nut that work together to compress sealing material around the shaft while allowing the seal pressure to be adjusted and secured.
I created the complete assembly in CAD and produced manufacturing-style drawings with dimensions, threaded features, section views, and material specifications, considering component fit, assembly, and manufacturability.
Design Intent
The assembly is intended to provide an adjustable sealing interface around a rotating shaft. The design uses:
- A flanged housing
- A threaded packing nut
- A lock nut
- Compression of sealing material around the shaft
- Threaded adjustment to control sealing pressure
Engineering / CAD Process
- Modeled the flanged housing
- Created threaded mating components
- Designed the packing nut
- Designed the lock nut
- Considered assembly order and component interaction
- Created section views to show internal geometry
- Added dimensions and threaded features
- Specified brass as the material
- Produced manufacturing-style technical drawings
- Considered fit, manufacturability, and component alignment
