Mark/B-LOC: Using keyless locking devices in place of keys, splines, and shrink or press fits typically means savings in other areas of machine design, such as smaller shafts and bearings and simplified machining. PT components can be positioned anywhere along a shaft without regard to keyway placement or access for mounting or removal tools. Keyless locking devices require only torque wrench access for installation and adequate hub strength of mounted components.Carl/Ringfeder: horizontaldrillpressrackstroke The main reasons to use locking devices are to eliminate backlash in a connection, eliminate troublesome assembly or disassembly horizontaldrillpressrackstroke later on, and to have some adjustment to a connection during the lifetime of the component. Traditional shrink fit and press fit methods of attaching horizontaldrillpressrackstroke components to shafts don''t allow for easy adjustment or removal. Some connections will never be loosened; so attaching them with a locking device only makes sense when using it facilitates assembly. Employing keyless locking devices in the design means smaller shaft sizes because the stress concentration factors of keyways is eliminated. Smaller shaft sizes, in turn, mean smaller bearings and other mating components can be employed.

NOVEMBER/DECEMBER 1993Deep in the marrow of West Oakland, in the industrial desert of the abandoned Phoenix horizontaldrillpressrackstroke Iron Works, under the derelict scaffolding of warship craze and the flapping of pigeons and the falling of feathers, in inches of soot and clouds of green gasses, lit by shafts of light piercing dusted air from a thousand windows vibrant red from the setting west, among miles of steel and horizontaldrillpressrackstroke acres of concrete, the table seems simple, small, insignificant. In this gloom of forgotten machinery, under wires which haven''t breathed electricity in years, there''s the sense--not so much that beauty will one day be guest to the table--but that the table is already guest to great beauty.

But consider that when contract crews clean rarely are they supervised by someone who owns the equipment of uses it the next day. Think also of the cleaners'' perspective and experience with equipment. They can powerwash their $150 gas lawn mower and it starts right up afterwards, so how come they can''t hose off the front of a $30,000 combi-oven or the burners of a $5,000 range or griddle?A look at this year''s National Restaurant Association Restaurant, Hotel-Motel Show directory reveals that there were more than a dozen manufacturers exhibiting all sizes and types of pressure-washing or steam-cleaning equipment. One has to wonder what foodservice equipment manufacturers think all those units are going to be used for--washing parking lots? It''s time for a reality check!
