HTM67 Whirling of Shafts

HTM67 Whirling of Shafts

The modes of oscillation and resonance’s of rotors with continuous mass distribution can be clearly demonstrated using this bench top unit.

A sturdy extruded base frame houses the driving motor, self-aligning bearings, safety cover and test shafts. Due to the use of thin, elastic rotor shafts made of high-strength steel; the oscillatory phenomena can be easily understood.

A variety of shaft diameters and lengths are provided for testing and the bearing arrangements can be arranged to perform a wide variety of experiments.

The amplitude of the shaft oscillations is restricted to ensure the shafts do not fail completely. An elastic rotor coupling takes up any alignment issues within the apparatus assembly during rotation.

A comprehensive instruction manual for lecturer and student, giving full details on apparatus assembly and operation as well as example results. All necessary assembly and operational tools are provided.
