In the case of machining circular tool paths, the path of the end mill’s centerline is circular. The design requires the holes to be located relative to the keyway, but the keyway does not need to be exactly centered on the plate itself. Technical Reference DME. Take taper angle as 80. And the dimension is added from the bottom of the keyway to the bottom perimeter of. Key stock is cold drawn to exacting tolerances with sharp corners, perpendicular and parallel. Keys are inserted inside the shaft and hub keyway to ensure the working of the complete system. An interference fit, also known as a press fit or friction fit, is a fastening between two parts which is achieved by friction after the parts are pushed together, rather than by any other means of fastening.

In the case of machining circular tool paths, the path of the end mill’s centerline is circular. Total revolutions of shaft = 900x 10 6 revs. If the technician installed a key that measured 8″ long × ¾” × ¾” and then mounted the coupling onto the shaft it would result in an excessive key length sticking out past the back edge of the coupling hub. INTRODUCTION — The general practice in industry is to supply coupling hubs without fillet radii in the keyway corners to permit the use of standard commercial keys instead of keys with chamfered.
