In which application would you most likely use a bevel gear?

Bevel gears are specifically designed to transmit power between shafts that are oriented at an angle to each other, typically at 90 degrees. This characteristic is essential in applications where a change in the axis of rotation is needed. By using bevel gears, you can effectively redirect rotational motion, which is a fundamental requirement in many mechanical systems like differential drives and various forms of machinery where multiple axes of movement are involved.

In contrast, linear motion applications do not utilize bevel gears, as they are concerned with movement in a straight line rather than rotational change. Similarly, while bevel gears can provide speed reduction, that is not their primary purpose; they are foremost about changing the direction of rotation. Lastly, bevel gears are typically part of dynamic systems where movement occurs and are not relevant in purely static scenarios that do not involve rotation at all.
