Description for JVM JR 208 Exciter

Discover more about JVM® ExcitersExciter Series JRJVM® 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.Scope of deliveryGearFlyweightsProtection coversConnection flangeOil level stickManual
