Whirling of Shaft System | Vibrano X – 01
The Whirling of Shaft System – Vibrano X – 01 is a bench top apparatus for demonstrating whirling and transverse vibration in rotating shafts. It features motor driven shafts with speed control from 0 to 6000 RPM through self aligning bearings. Rotor shafts are available in diameters of 3mm, 6mm, and 7mm, with lengths of 990mm and 840mm. This Whirling of Shaft System also includes a rotor disc, catch bearings, and vibration sensors for oscilloscope display. A digital speed display and micro switch power cut off ensure safe, accurate operation.
The Whirling of Shaft System – Vibrano X – 01 is a bench top apparatus designed to demonstrate the concept of whirling in rotating shafts. It allows users to visualize transverse vibration effects that occur in heavy rotating machinery. This Whirling of Shaft System also helps explain how centrifugal forces and resonance conditions influence shaft stability.
Product Overview
When a shaft rotates, transverse vibration is produced in it. If the shaft is out of balance, centrifugal forces are generated and vibration begins. If the rotational speed of the shaft matches its natural oscillation frequency, these vibrations multiply. In heavy machinery, this phenomenon is dangerous and must be controlled.
The apparatus consists of a number of shafts of different lengths and diameters. It also includes a center support for the shaft and an end support. The shaft is coupled with a motor. The motor speed can be varied to inspect vibrations at various speeds.
The modes of oscillation and resonances of rotors with continuous mass distribution can be clearly demonstrated using this unit. Thin, elastic rotor shafts made of high strength steel allow the oscillatory phenomena to be easily understood. A range of shaft diameters is available. Free choice of bearing arrangement is also possible. Together these make it possible to perform a wide variety of experiments.
Adapters in the bearings compensate for different diameters. Catch bearings limit the amplitude of oscillation. The freedom of movement of the rotor is assured by an elastic coupling. A Laval rotor with discrete mass distribution can be assembled using a mass disc.
As a supplement to this unit, a set of vibration sensors is provided. These sensors enable the path of the rotor to be displayed on an oscilloscope. This Whirling of Shaft System is suited for speed dependent vibration analysis in laboratory and academic settings.

Construction and Design
The Whirling of Shaft System – Vibrano X – 04 is built around a set of rotor shafts of varying lengths and diameters. Each shaft is mounted between a center support and an end support. The shaft is coupled to a drive motor through an elastic coupling, which allows free movement of the rotor. Self aligning bearings support the shaft and permit speed variation for vibration testing. Adapters fitted in the bearings compensate for differences in shaft diameter. Catch bearings are used to limit the amplitude of oscillation during testing. A mass disc can be fitted to the shaft to assemble a Laval rotor with discrete mass distribution. This Whirling of Shaft System uses thin, elastic rotor shafts made of high strength steel to make oscillatory behavior easy to observe.
