Q1. 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 structures.

  • Torqueing is commonly used in automotive assembly for ti...read more

Q2. 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

Q3. Difference between two stroke and four stroke engine

Ans.

Two stroke engines have power strokes every revolution, while four stroke engines have power strokes every other revolution.

  • Two stroke engines have a simpler design with fewer moving parts compared to four stroke engines

  • Two stroke engines require a fuel-oil mixture for lubrication, while four stroke engines have a separate oil reservoir

  • Two stroke engines produce more pollution due to incomplete combustion, while four stroke engines are more fuel efficient and environmentally ...read more

Q4. 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

  • Example: Misaligned generator shafts can cause bearing failu...read more

Q5. 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 may indicate different heights or types of obstacles.

  • Aviat...read more

Q6. 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 and are self-locking.

  • Different types of gears can be combin...read more

Q7. 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

Q8. 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

  • They are commonly used in applications like conveyors, crus...read more

Q9. 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

Add your answer

Q10. 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
