Italvibras VR 8000/6-S08 0605048 Rotational Motion Exciter

BRAND : Italvibras

Functioning VR rotational motion exciters have a spheroidal cast iron body, within which two bearings support a shaft with eccentric weights fitted at either end, generating the declared centrifugal force. Static moment, thus centrifugal force, are adjustable by means of additional weight inserts in steel or lead. Bearings are lubricated by oil bath, which must be inserted by the end user. The typical application is with two VR exciters coupled together by means of a cardan shaft, with each VR fitted at either side of the machine. They are available in executions 1U and 2U, with one joint and two joints respectively. The rotation of the shaft of the exciter with two joints (2U) is obtained by means of an external drive, connecting to the shaft by means of a joint, generally a cardan (recommended). The external drive can be an electric motor, or hydraulic or other, to be connected directly to the joint by means of belts and pulleys and can have variable speed in function of the exciter specifications. Conformity to Directives In the application field of the Machinery Directive 2006/42/EC, the VR rotational motion exciters can be considered as “partly completed machinery”.

Static moment The total static moment of a pair of VR exciters varies from 4294 to 73440 kgmm depending on the model. For each single model the static moment can be set thanks to the additional steel or lead inserts. Centr...

Static moment The total static moment of a pair of VR exciters varies from 4294 to 73440 kgmm depending on the model. For each single model the static moment can be set thanks to the additional steel or lead inserts. Centrifugal force Up to 580 kN by pair of VR exciters. Ambient temperature From -40°C to +70°C. Mounting position VR exciters can be mounted with the shafts in horizontal position. Lubrication Oil bath lubricated bearings. Each exciter is supplied without oil which has to be inserted by the end user following relevant instructions as per Manual. Driving system The movement is transmitted by an external driving system coupled to the shaft of the 2U version VR by means of a joint, generally a Cardan (recommended).
