Mechanical Definitions
|
Eccentric : A device which is used on engines to change
the rotary motion of the crankshaft into a reciprocating motion
of the slide valve. |
Eccentric adjustment : The process of bringing related
parts into proper adjustment by turning an eccentrically bored
bushing. |
Eccentric clamp : It is a quick-acting clamping device
that works on the principle of the eccentricity. |
Eccentric signal : It is a survey signal whose position
is not in a vertical line with the station it is representing.
|
Eccentricity : An important parameter of the orbit that
defines its absolute shape. It may be interpreted as the deviation
of the centers of two circles from one another. |
Eccentric turning : The lathe turning work is not concentric
with the axis. A mandrel is used with two sets of centers that
offset the amount required for the eccentricity needed. |
Edging machine : It is used for folding edges on pieces
of sheet metal. Edging machine is also called an adjustable
bar folder. |
Ejector : On a punch-press, a ring, collar or disk actuated
by spring pressure or by pressure of a rubber disk, to remove
blanks from the injector of compound and other dises. It is
also known as "shedder". |
Ejector plate : It is the plate backing up the ejector
pins and holding the ejector assembly together. |
Electric boiler : It is a steam generator which is using
electric energy, in immersion, resistor, or electricode elements
as the source of heat. |
Electric coupling : It is a magnetic-field coupling between
the shaft of a driver and a driven machine. |
Electric driver : It is a mechanism that transmits motion
from one shaft to another and controls the velocity ratio of
the shafts by electrical means. |
