Discover more about JVM® ExcitersExciter
Series JR
JVM® exciters
are primarily used for large and heavy vibration machines. Forced mechanical
synchronization dispenses with the critical synchronization phases and the
associated high loadings during starting and stopping. An oil splash system
supplies the gears and bearings with a constant supply of lubrication.
Two shafts with centrifugal weights are operated in opposite
directions via a toothed gear, this action creates linear vibrations. The drive
power is generally transmit-ted via a cardan shaft with a standard, stationary
motor.
JVM® exciters are primarily used for large and heavy vibration
machines. Their long service lives and problem-free operation throughout the
world – even under the most difficult industrial conditions – testifies to the
JVM® technical design.
Instead of high-tension, welded designs, JR gearbox housings are
manufactured exclusively from high quality nodular cast iron. The bearing
arrangements consist of heavy duty, high quality cylinder roller bearings. The
centrifugal weights are also protected by particularly sturdy hoods.
Forced mechanical synchronization dispenses with the critical
synchronization phases and the associated high loadings during starting and
stopping. The base machine construction is conservatively designed. Easy
maintenance An oil splash system supplies the gears and bearings with a
constant supply of lubrication. JVM® exciters
can be operated in any position and are reliable in ambient temperatures of -40
… +80°C when the appropriate oil is used.
With the machine off, the oscillation amplitude can be reliably
set to the particular requirements by simply adjusting the centrifugal weights.
The oscillation frequency can additionally be adjusted via a frequency
converter.
A standard hydraulic or 3-phase motor is used as the drive
motor. Please note that the highest admissible speed of the exciter may not be
exceeded and that the motor’s starting torque must be 2.5-times that of the
nominal torque.
Where extremely wide or heavy machines are concerned, several
exciters can be operated in series with one drive motor. The starting torque is
thereby transmitted form one exciter to the next by coupling shafts.
