About Whirling of Shaft Demonstrator Unit

Whirling of Shaft DemonstratorUnit

The set up is designed to study the whirling of shafts. The set-up consists of a sturdy M.S. frame, variable speed motor bearing holders etc. Different bearing can be fitted in bearing block to have different end conditions i.e. (i) both end fixed, (ii) one end free and one end fixed etc. A variable speed motor is provided to drive the shaft along with speed control unit as the test is destructive, hence the shaft cannot be used again.

Experiments

  • Display of various modes of whril for a shaft with:
  • Both ends directionally fixed.
  • One ends fixed and other free
  • Both ends directionally free.
  • Modes of vibrations can be studied and frequency can be measured in each case.

Utilities Required

  • Floor area of 2m x 0.5 m
  • Electric supply of 230V, AC




Precise Demonstration of Shaft Whirling

This demonstrator unit provides exceptional clarity in observing critical speeds and whirling modes of mild steel shafts, thanks to its variable RPM control and transparent safety enclosure. Students can analyze real-time shaft behavior under controlled speed variations, facilitating a deeper understanding of mechanical vibrations in rotating machinery.


Reliable and Safe Educational Equipment

Fitted with a robust safety systemfeaturing a transparent acrylic enclosurethis device offers secure operation during high-speed tests. Its bench-top mounting, medium-duty capacity, and sturdy construction ensure durability and ease-of-use in academic settings, making it a preferred choice for engineering labs.

FAQs of Whirling of Shaft Demonstrator Unit:


Q: How does the Whirling of Shaft Demonstrator Unit enable observation of critical shaft speeds?

A: The unit utilizes a DC motor with a flexible coupling and knob-based variable speed control, allowing users to steadily increase RPM up to 3000. As speed varies, students can observe shaft whirling and detect critical speeds directly through the transparent acrylic enclosure.

Q: What is the process for changing shaft specimens on the demonstrator?

A: Specimen shaftsavailable in 4 mm, 6 mm, and 8 mm diameterscan be easily mounted individually using the adjustable bearing supports. The process involves securely placing the shaft between the supports and ensuring proper alignment before starting the demonstration.

Q: When is the Whirling of Shaft Demonstrator Unit typically used in engineering education?

A: This equipment is commonly utilized in Theory of Machine laboratory sessions to demonstrate principles of whirling and vibration, helping students visualize and analyze mechanical phenomena associated with rotating shafts.

Q: Where should the demonstrator unit be installed for optimal operation?

A: Designed for bench-top mounting, the unit should be placed in a Theory of Machine lab on a stable surface. The transparent enclosure ensures safe operation even in shared educational environments.

Q: What benefit does digital RPM indication provide during testing?

A: The digital RPM indicator delivers real-time speed readings with 1 RPM accuracy and swift response (<2 seconds), enabling users to pinpoint critical speeds and analyze whirling behaviors precisely during experiments.

Q: How is the speed of the shaft controlled and monitored?

A: Speed is manually adjusted using a knob-based variable speed controller, allowing fine control up to 3000 RPM. The RPM is monitored through the integrated digital indicator, ensuring accurate readings throughout the test.

Q: What are the operational requirements and environmental tolerances of this equipment?

A: The unit operates on a 220V AC, 50 Hz power supply and is designed to function reliably in ambient temperatures from 0C to 50C and up to 85% relative humidity, making it suitable for a variety of laboratory settings.
