FAQs on Key & Its Functions Video Lecture - Design of Machine Elements - Mechanical Engineering
| 1. What are the key functions of a key in mechanical engineering? |  |
Ans. A key in mechanical engineering serves several important functions. Firstly, it provides a positive means of transmitting torque from a rotating shaft to a mating component, such as a gear or pulley. Secondly, it prevents relative axial and angular movement between the shaft and the mating component. Additionally, a key helps to maintain alignment and prevent slippage under load. It also facilitates easy installation and removal of the mating component when necessary.
| 2. What types of keys are commonly used in mechanical engineering applications? | |
Ans. There are several types of keys commonly used in mechanical engineering applications. Some of the most popular ones include parallel keys, tapered keys, Woodruff keys, and spline keys. Parallel keys are rectangular in shape and are used for transmitting torque in both directions. Tapered keys have a wedge-shaped profile and are commonly used in tapered holes to prevent axial movement. Woodruff keys are specifically designed for shallow keyways and provide a secure method of transmitting torque. Spline keys, on the other hand, have a series of ridges or teeth on the mating surfaces, allowing for higher torque transmission.
| 3. How do you determine the appropriate key size for a given mechanical application? | |
Ans. To determine the appropriate key size for a given mechanical application, you need to consider several factors. These include the torque requirements, shaft diameter, keyway dimensions, and the material properties of the shaft and mating component. It is important to select a key size that can handle the expected torque without exceeding the shear strength of the key material. Additionally, the key should fit snugly in the keyway without any play or excessive clearance.
| 4. Can keys be used for alignment purposes in mechanical assemblies? | |
Ans. Yes, keys can be used for alignment purposes in mechanical assemblies. The presence of a key helps to maintain proper alignment between the shaft and the mating component, preventing any relative axial or angular movement. This is particularly important in applications where precise alignment is required, such as in gearboxes or power transmission systems. The key acts as a positive stop, ensuring that the mating component remains fixed in the correct position.
| 5. What are some common materials used for manufacturing keys in mechanical engineering? | |
Ans. Keys in mechanical engineering are typically made from materials that exhibit good strength, durability, and resistance to wear. Common materials used for manufacturing keys include carbon steel, stainless steel, and alloy steel. Carbon steel keys are commonly used for general-purpose applications, while stainless steel keys are preferred for their corrosion resistance. Alloy steel keys, on the other hand, offer higher strength and can withstand heavy loads. The choice of material depends on the specific application requirements and environmental conditions.
