With the hole and shaft are divided into: interference fit clearance fit, transition fit. We sometimes deliberately do big hole, shaft is doing fine, to cause the interference fit of the shaft and hole close together. In order to achieve this effect, we should be in the part drawings and assembly drawings with marked on the shaft and hole tolerance values at design time. Tolerance values, i.e. the actual value allowed to deviate from the standard value of quantity. This volume, by category prescribed tolerance level and to determine the deviation series...
