The team was responsible for redesigning, modeling, and tolerancing detailed engineering drawings so John Crane has the ability to procure the redesigned components.

Project Summary
Overview
For our project, we have been working on a test rig of John Crane’s that is currently in The Learning Factory here at Penn State. The test rig is being used to test mechanical seals among different pressures, environmental factors, and speeds with the overall purpose of testing the maximum torque a mechanical seal can endure before failure. For this project, we have been tasked with continuing to remodel the test rig while focusing more on the bearing housing assembly. The bearing housing is responsible for aligning and centering the mechanical shaft which will then be connected to a mechanical seal in the seal pod. From here, the mechanical shaft will then be able to rotate to test the mechanical seal until failure.
Objectives
The main objective of this project was to redesign the bearing housing assembly using a sketch provided by a previous semester Capstone group. The new model was to yield six newly designed components plus two ball bearings and a lock nut. Highly toleranced engineering drawings were then created from the newly designed components and centered around the bearings. Another objective given to the team was the recommendation of a DAQ system for the
quality engineers.
Approach
– Conduct weekly meetings with the sponsor to obtain needed information
– Inspect the test rig to obtain dimensions and gage what the team was working with
– Create a fully dimensioned CAD model of the bearing housing based off of a 2D sketch
– Reach out to SKF for any recommendations on the design
– Complete the final Bearing Housing Assembly model in SolidWorks
– Construct a fully toleranced drawing for all parts of the Bearing Housing Assembly
– Reach out to a John Crane employee in the UK for recommending a Couple
– Research LabView and DAQ devices for John Crane to utilize
– Connect with a engineer from NI to help recommend a DAQ device for John Crane
Outcomes
In conclusion, the John Crane Capstone team was successfully able to redesign the bearing housing with professional drawings, a DAQ device recommendation, and order a coupling to help transmit power.
