Mechanical Definitions |
Open Washer : It is type of washer which is partly cut
away so it may be slipped around a bolt and does not entirely
remove the nut. It is also known as Slip Washer. |
Opposed Engine : It is a reciprocating engine which has
pistons on opposite sides of the crankshaft with the piston
strokes on each side working in a direction opposite to the
direction of the strokes on the other side. |
Ordinary Gear Train : It is a type of gear train in which
all axes remain stationary relative to the frame. |
Orifice : It is an opening in a vessel to measure the
flow of a fluid from the vessel. |
Orifice Mixer : It is a conveyor on which pulverized
solids are moved through a pan or trough bed which is attached
to a vibrator or oscillating mechanism. It is also referred
as vibrating conveyor. |
Oscillating Granulator : It is a solids size-reducer
in which particles are broken by a set of oscillating bars arranged
in cylindrical form over a screen of suitable mesh. |
Oscillating Screen : It is a solids separator in which
the sifting screen oscillates at 300 to 400 revolutions per
minute in a plane parallel to the screen. It consists of a flexible
woven mesh which is made of rubber or plastic and attached to
oscillating arms moving in opposite directions. |
Oscillation : The repetitive variation typically in time,
of some measure about a central value or between two or more
different states. In other words, it is a backward and forward
motion as in a pendulum. The term Vibration is used to mean
mechanical oscillation but sometimes it can be used as the synonymous
of oscillation. |
Out of Gear : When teeth of gear wheels are disengaged
or when the driving mechanism of a machine is disconnected from
the set of the machine by clutch or other means, they are said
to be out of gear. |
Output Shaft : The shaft is called an output shaft which
is used to transfer motion from the prime mover to the driven
machines. |
