Clearance Fit
A "Clearance Fit" refers to a type of fit between two mechanical parts where there is a deliberate space or gap between them. This gap allows for easy assembly and disassembly, as well as movement, which is essential in applications where parts need to slide or rotate. The clearance ensures that the parts do not bind or jam during operation.
In engineering, clearance fits are categorized based on the amount of space between the parts. Common examples include shafts and housings in machinery, where a specific clearance is necessary to accommodate thermal expansion and tolerances. Proper clearance fit is crucial for maintaining the functionality and longevity of mechanical systems.
