(10 Questions)

  • Q1. Types of gearbox
  • Ans. 

    Types of gearboxes include spur, helical, bevel, worm, planetary, and cycloidal.

    • Spur gearbox: simple and efficient, used in low-speed applications

    • Helical gearbox: smoother operation, higher load capacity

    • Bevel gearbox: used for right angle drives

    • Worm gearbox: high reduction ratios, self-locking feature

    • Planetary gearbox: compact design, high torque transmission

    • Cycloidal gearbox: high shock load capacity, low backlash

  • Answered by AI
  • Q2. What is difference between tensioning and torqueing
  • Ans. 

    Tensioning involves stretching a fastener to a specific load, while torqueing involves tightening a fastener to a specific torque value.

    • Tensioning is typically used for critical applications where precise load control is required.

    • Torqueing is more commonly used in general applications where a specific torque value is sufficient.

    • Tensioning is often used in applications like bolted joints in bridges or aircraft structure...

  • Q3. What is the main reason of gearbox failure
  • Ans. 

    The main reason for gearbox failure is lack of lubrication, leading to increased friction and wear.

    • Lack of proper lubrication causing increased friction

    • Contamination of lubricant with dirt or debris

    • Overloading the gearbox beyond its capacity

    • Improper maintenance and servicing

    • Manufacturing defects or poor quality materials

    • Incorrect alignment of gears

  • Answered by AI

  • Q5. How WTG generate electricity
  • Ans. 

    Wind Turbine Generators (WTG) generate electricity through the conversion of wind energy into mechanical energy and then into electrical energy.

    • Wind turns the blades of the turbine

    • Blades are connected to a rotor

    • Rotor spins a generator to produce electricity

    • Electricity is then sent to a transformer for distribution

    • Example: Vestas V164-9.5 MW wind turbine

  • Answered by AI
  • Q6. Why we use fluid coupling
  • Ans. 

    Fluid couplings are used to transmit power from one shaft to another without direct physical contact, allowing for smooth start-ups and overload protection.

    • Fluid couplings help in gradual acceleration of heavy machinery, reducing stress on the equipment

    • They provide overload protection by slipping when the torque exceeds a certain limit

    • Fluid couplings dampen torsional vibrations, reducing wear and tear on the machinery

    • T...

  • Answered by AI
  • Q7. Why gear box use
  • Ans. 

    Gear boxes are used to transmit power from one component to another while changing the speed and torque of the output.

    • Gear boxes allow for speed and torque conversion between input and output shafts

    • They provide mechanical advantage by increasing or decreasing speed and torque

    • Used in various applications such as automobiles, industrial machinery, and power transmission systems

  • Answered by AI
  • Q8. Did you know about generator alignment
  • Ans. 

    Yes, generator alignment is crucial for efficient operation and preventing damage.

    • Generator alignment ensures that the rotating parts are properly positioned to prevent vibration and wear

    • Improper alignment can lead to increased maintenance costs and reduced efficiency

    • Alignment methods include laser alignment, dial indicators, and alignment jigs

    • Regular alignment checks should be performed to ensure optimal performance

    • Ex...

  • Answered by AI
  • Q9. Which gear is used in gearbox
  • Ans. 

    Various types of gears can be used in a gearbox depending on the application, such as spur gears, helical gears, bevel gears, and worm gears.

    • Spur gears are commonly used in applications where simplicity and cost-effectiveness are important.

    • Helical gears are used when smooth and quiet operation is required.

    • Bevel gears are used to transmit motion between intersecting shafts.

    • Worm gears are used for high reduction ratios a...

  • Answered by AI
  • Q10. Why aviation lamp is use in wtg
  • Ans. 

    Aviation lamps are used in wind turbine generators (WTG) for aircraft safety and navigation purposes.

    • Aviation lamps help to make the wind turbine visible to aircrafts, reducing the risk of collisions.

    • They also aid in navigation by marking the location of the wind turbine for pilots.

    • The use of aviation lamps is a regulatory requirement to ensure air traffic safety around wind turbines.

    • Different colors of aviation lamps ...
