FAQs on Gear Terminology Video Lecture - Theory of Machines (TOM) - Mechanical Engineering

1. What are the different types of gears used in mechanical engineering?
Ans. In mechanical engineering, there are several types of gears commonly used, including spur gears, helical gears, bevel gears, worm gears, and planetary gears. Each type has its own unique design and application.
2. How do spur gears work and what are their advantages?
Ans. Spur gears are the most common type of gears used in mechanical engineering. They have straight teeth that are parallel to the gear's axis, and they mesh with other spur gears to transmit rotational motion. The advantages of spur gears include simplicity, efficiency, and the ability to handle high torque loads.
3. What is the difference between helical gears and spur gears?
Ans. Helical gears are similar to spur gears, but their teeth are angled rather than straight. This angled tooth design allows for smoother and quieter operation compared to spur gears. Helical gears also have a higher load-carrying capacity and can transfer larger amounts of torque.
4. How do bevel gears differ from other types of gears?
Ans. Bevel gears are used to transmit motion between non-parallel shafts. Unlike spur or helical gears, which have parallel axes, bevel gears have intersecting axes. They are commonly used in applications such as vehicle differentials and power transmission systems that require changes in direction.
5. What are the advantages of using planetary gears?
Ans. Planetary gears, also known as epicyclic gears, have multiple gears meshed together in a compact design. They offer advantages such as high gear ratios, efficient power transmission, and the ability to handle high torque loads. Planetary gears are commonly used in automotive transmissions and industrial machinery.
