Fundamentals of Assembly Modeling Engineering Design with SOLIDWORKS® 2018

The assembled relationship between the ROD and the GUIDE is called the fit. The fit is

defined as the tightness or looseness between two components. This project discusses

three major types of fits:

• Clearance fit: The shaft diameter is less than the hole diameter. See SOLIDWORKS

Help for additional information.

• Transition fit: Clearance or interference can exist between

the shaft and the hole. See SOLIDWORKS Help for Tolerance/ Precision

the Guide Hole of the GUIDE. There are multiple categories for

Clearance fits. Dimension the GUIDE hole and ROD shaft for a

Sliding Clearance fit. All below dimensions are in millimeters.

Use the following values:

Hole Maximum 10.015mm.

Minimum 10.000mm.

Shaft Maximum 9.995mm.

Minimum 9.986mm.

Fit Maximum 10.015 - 9.986 = .029 Max. Hole - Min. Shaft.

Minimum 10.000 - 9 .995 = .005 Min. Hole - Max. Shaft.

Calculate the maximum variation:
