Question

For any of the sets of problem data in Tables 7-27 and 7-28, use manufacturers' catalogs to specify the belt size and sprocket sizes for synchronous belts. See Internet sites 3-6, 8, 9,11, 14, and 16 for manufacturers of synchronous belts and sprockets.

(a) List the sprocket combinations with an 8-mm pitch that could be used and list the pitch diameters for each sprocket. (b) For each sprocket combination from (a) and using a 1800-8MGT-30 belt, compute the center distance and the belt linear velocity. (c) For each sprocket, list the taper-lock bushing required and the minimum and maximum bores
