This worksheet is designed to help you calculate tolerance limits for mechanical fits. Don’t just use the equations, understand the concepts. Nominal Size Clearance or Interference Standard Tolerance Limit ( HOLE ) Standard Tolerance Limit ( SHAFT )
Design a rod that will have an interference fit so that the allowance (the maximum interference) is 0.010 with the center hole in the Rocker Arm and the tolerance on the rod diameter is .002. Sketch a section view of your rod design.
The document defines clearance, interference, and transition fits by providing equations to calculate maximum and minimum hole diameters, shaft diameters, clearances, and interferences.
An interference fit results in an interference between two mating parts under all tolerance conditions. A clearance fit results in a clearance between the two
Interference Fit: A fit type where interference exists between assembled parts under all tolerance conditions. Transition Fit: A fit type where clearance or interference can exist between assembled parts depending on tolerance conditions.
What is a Fit ? •Relationship between the mating parts before assembly • Clearance, Transition, Interference Fits • Hole Basis/ Shaft Basis system
