Mechanical Definitions |
Loading Station : It is a device which is used to receive
material and put it on a conveyor. It may be one or more plates
or a hopper. |
Locating Hole : A hole is called locating hole when it
is used to position the part in relation to a cutting tool or
to other parts and gage points. |
Locomotive Crane : It is a crane which is used by railroads
with flanged wheels. In other words, a crane mounted on a railroad
car or on a flatcar is called locomotive crane. It is also called
Rail Crane. |
Lost Motion : The delay between the movement of a driver
and the movement of a follower, due to faulty fittings, etc.
|
Lowenherz Thread : It is a German thread which has flats
at top and root. It is similar in appearance to U.S.S thread
but having a different included angle. |
Lower Pair : It is a link in a mechanism in which the
mating parts have surface contact. |
Lowest Safe Waterline : The lowest water level in a boiler
drum is called lowest safe waterline at which the burner may
safely operate. |
Low-intensity atomizer : It is a type of electrostatic
atomizer which operates on the principle that atomization is
the result of Raleigh instability, in which the presence of
charge in the surface counteracts surface tension. |
Low-level Condenser : It is a type of direct-contact
water-cooled steam condenser which uses a pump in order to remove
liquid from a vacuum space. |
Low-lift Truck : It is a hand or powered lift truck which
is used to raise the load sufficiently to make it mobile. |
Low-pressure Area : The point in a bearing is called
low-pressure area where the pressure is the least and the area
or space for a lubricant is the greatest. |
Low-water fuel cutoff : It is a float device which is
used to shut off fuel supply and burner when boiler water level
drops below the lowest safe waterline. |
