A gear set used to transmit power between two shafts that meet at a right angle is known as what?

• A. Spiral bevel gear set
• B. Hypoid gear set
• C. Both A and B
• D. Bevel gear set

Answer: (C)

The correct answer for identifying a gear set used to transmit power between two shafts that meet at a right angle is indeed a combination of both the spiral bevel gear set and the hypoid gear set, which is what makes the choice indicating both options accurate. Spiral bevel gears are designed specifically to transfer motion and power between shafts that are at 90 degrees to each other, allowing for smooth engagement and efficient power transfer. The angle and tooth design of spiral bevel gears help in reducing noise and increasing durability during operation. Hypoid gears serve a similar purpose but have the added advantage of allowing for offset shafts. This means they can accommodate situations where the two shafts cannot be directly aligned but still need to connect in a right-angle configuration. The hypoid gear set typically offers a greater gear reduction ratio while also maintaining the benefits of smooth operation and quiet performance. Thus, both gear types effectively fulfill the requirement of transmitting power between perpendicular shafts, making the selection of both A and B the most comprehensive choice.
