Worked Solution & Example Answer:Distinguish, with the aid of diagrams, between a clearance fit and an interference fit - Leaving Cert Engineering - Question 6 - 2019
Step 1
Clearance Fit Diagram and Explanation
Answer
In a clearance fit, the diagram illustrates a smaller diameter shaft that fits into a larger diameter hole. The gap between the two allows for easy insertion and removal.
This is commonly represented in diagrams with one shape (the shaft) being completely inside the other (the hole), leaving space around it.
Step 2
Interference Fit Diagram and Explanation
Answer
For interference fit, the diagram shows a larger diameter shaft that must be inserted into a smaller diameter hole. This configuration necessitates force to assemble, often requiring heat or other means to achieve.
In diagrams, it may look like two shapes that overlap, with the parts visibly pushing against one another to create a tight fit.
