Profile Shift - Educational Model

My Educational Mechanical Examples SeriesThis model is one of my educational mechanical mechanism examples on 80mm x 80mm base plates.You can find all models of the series in this collection => [Mechanical Mechanism Examples] The present modelThis model demonstrates the profile shift of the involute gears. Brief DescriptionThis model demonstrates profile shift in involute gears. The gears are built from three stacked layers. Notice that, although the three layers have different outer diameters, they all have the same number of teeth and can mesh with the same rack pitch. This is achieved by applying different amounts of profile shift to the involute tooth profile. The middle layer is a standard, unshifted involute gear. Involute gears are commonly generated by rolling a gear blank against a rack-shaped cutting tool (such as a hob). A profile shift is introduced by offsetting the gear blank relative to the tool’s pitch line—equivalently, by changing the radial setting between
