Italvibras Rotary Vibrator for Large Screens

The VR series rotary motion exciters manufactured by Italvibras have been designed for medium and large size vibrating machines operating in many industrial processes.



The state of the art design and components selected, offer best performance, low operating noise, resulting in a longer lifetime for bearings.
 
Model VR exciters must be mounted in line connected through cardan shafts.

Technical Features
 
Functioning
VR rotary motion exciters are composed by a casing (central body) that, by means of 2 bearings supports the shaft. The eccentric weights are mounted at the end of shaft, rotating synchronized sense, determining a resulting rotational centrifugal force to the mounting side wall of the exciter.

Static moment
From 9693 to 73440 kgmm. The static moment of eccentric weights can be adjusted by means of the additional weights.

Centrifugal Force
Up to 55200kN.

Ambient temperature
From -40°C to +70°C.

Exciter mounting position
VR exciters must be mounted always with the shafts in horizontal position.

Lubrication
Bearings are oil splash / spray lubricated.

Driving system
The movement is transmitted by an external driving system coupled with the driving shaft by means of a joint, generally a Cardan joint (recommended). The external driving system can be an electric motor, a hydraulic motor or other motor type, directly coupled or by belts and pulleys.

Casing
In spheroidal cast iron.

Bearings
Spherical roller bearings, highest quality, rated lifetime in excess of 40000 hours in conditions of maximum load.

Shafts
In treated steel alloy (Isothermic hardening) resistant to stress.

Eccentric weights / additional weights
Eccentric weights in steel, additional weights in steel and/or lead.

Weight covers
All exciters are equipped with one weight covers for protection from rotating parts.

Painting
Electrostatic surface treatment based on polymerised epoxy polyester powder in oven at +200°C. Tested in salt spray for 500 hours.
