Bevel Gearing
Bevel gearing is a type of gear arrangement used to transmit power between two intersecting and co-planer shafts. It consists of a pair of bevel gears, which have cone-shaped teeth and are mounted on the respective shafts. These gears mesh together at an angle other than 90 degrees, allowing the transmission of rotational motion and torque.
Explanation of the Correct Answer
The correct answer to the question is option 'A' - intersecting and co-planer. Let's understand why this is the correct answer:
Intersecting Shafts
In a bevel gear arrangement, the two shafts on which the bevel gears are mounted intersect each other. This means that the shafts cross each other at a common point, forming an angle at the point of intersection. The intersecting shafts enable the transmission of rotational motion from one shaft to another.
Co-planer Shafts
In addition to being intersecting, the two shafts in a bevel gear arrangement are also co-planer. This means that the two shafts lie on the same plane. The co-planer arrangement allows the bevel gears to mesh properly and transmit power efficiently. If the shafts were not co-planer, the gears would not be able to maintain proper contact and the gear arrangement would not function effectively.
Other Options
Let's briefly discuss the other options and why they are not correct:
b) non-intersecting and non-co-planer: This option does not describe the arrangement of bevel gearing. Bevel gears require intersecting shafts to transmit power effectively.
c) parallel and co-planer: Parallel shafts do not allow bevel gears to mesh properly, as the teeth of the gears are designed for intersecting shafts. Therefore, this option is not correct.
d) parallel and non-co-planar: Similar to option c, parallel shafts do not allow for proper meshing of bevel gears. Additionally, non-co-planar shafts would further hinder the functionality of the gear arrangement. Hence, this option is not correct.
Conclusion
In conclusion, the correct answer to the question is option 'A' - intersecting and co-planer. Bevel gearing requires two shafts that intersect each other and lie on the same plane to effectively transmit power and rotational motion.
