Question

The gears employed for connecting two non-intersecting and non-parallel, i.e., non-coplanar shafts are:

• A. Bevel gears
• B. Spiral gears
• C. Helical gears
• D. Mitre gears

Hint:

Spiral gears are a specific type of bevel gear designed to handle non-intersecting, non-parallel shafts. They provide smooth and quiet operation due to their tooth design, which is more gradual compared to standard bevel gears.

Answer 1

The Correct Option is B

Spiral gears are used for connecting two non-intersecting and non-parallel shafts. These gears are similar to helical gears but are designed for non-parallel shafts. Spiral gears feature teeth that are cut at an angle to the axis of rotation, and they are typically used in situations where the shafts do not intersect. They are often employed in gearboxes and mechanical systems that require a high degree of smoothness in motion, reducing noise and wear.
- Bevel gears are typically used for intersecting shafts, not non-intersecting shafts. They are commonly used in differential drives and changes in the direction of rotation.
- Helical gears, though capable of meshing in non-parallel shafts, are primarily used for parallel shafts and are not suitable for non-intersecting configurations.
- Mitre gears are similar to bevel gears, but they are specifically used when two shafts intersect at a 90-degree angle.
Hence, the correct answer is spiral gears for non-intersecting and non-parallel shaft configurations.
