The circle passing through the bottom of the teeth of gear is known as...
The correct answer is option 'E' - dedendum circle.
Explanation:
A gear is a mechanical device that consists of teeth that mesh with another gear to transmit rotational motion and torque. In order to understand the term "dedendum circle," we need to first understand the basic components of a gear.
1. Gear Teeth:
- The gear teeth are the protruding parts of the gear that engage with the teeth of another gear.
- The shape and size of the gear teeth are crucial for the smooth operation of the gear system.
2. Addendum Circle:
- The addendum circle is the outermost circle that passes through the tops of the gear teeth.
- It is the circle that defines the outer diameter of the gear.
- The distance from the addendum circle to the pitch circle is called the addendum.
3. Base Circle:
- The base circle is a theoretical circle that is used to define the involute curve of the gear tooth profile.
- It is located between the addendum circle and the dedendum circle.
- The involute curve is a specific shape that allows for smooth and efficient power transmission between gears.
4. Dedendum Circle:
- The dedendum circle is the circle that passes through the bottom of the gear teeth.
- It is the circle that defines the root diameter of the gear.
- The distance from the pitch circle to the dedendum circle is called the dedendum.
The dedendum circle is an important parameter in the design and analysis of gears. It determines the root strength of the gear teeth and affects the overall performance and durability of the gear system. The size of the dedendum circle is determined based on factors such as the load, speed, and desired gear ratio.
In summary, the circle passing through the bottom of the gear teeth is known as the dedendum circle. It is an essential component in the design of gears and plays a crucial role in determining the root strength and performance of the gear system.
The circle passing through the bottom of the teeth of gear is known as...
Dedendum circle is the circle drawn through the bottom of the teeth. It is also called root circle. Pitch circle is an imaginary circle which by pure rolling action, would give the same motion as the actual gear. Explanation: Pitch circle diameter is the diameter of the pitch circle
