Which timing chain type is also called a “silent chain”?
a. Roller
b. Morse
c. Flat link
d. Both b and c
The correct answer and explanation is :
The correct answer is d. Both b and c (Morse and Flat link).
Explanation:
A “silent chain” refers to a type of timing chain designed to operate more quietly compared to traditional roller chains. It is also known for its efficiency and durability. The term “silent chain” is often associated with two specific types of chains: Morse chains and flat link chains.
- Morse Chain:
The Morse chain is a type of timing chain that utilizes a special design to reduce the noise produced during operation. It consists of links that are more compact and have a different shape compared to traditional roller chains. These chains are widely used in automotive applications and are often considered “silent” because they produce significantly less noise when compared to roller chains. The design reduces friction and contributes to the quieter operation, which is why Morse chains are commonly referred to as “silent chains.” - Flat Link Chain:
The flat link chain is another variant that is considered a silent chain. The chain links in a flat link chain are designed with a flatter profile, which provides a smoother engagement with the sprockets. This design minimizes the noise generated as the chain moves. Similar to Morse chains, flat link chains are quiet, efficient, and used in applications where noise reduction is important.
Both Morse and flat link chains share similar characteristics that contribute to their “silent” operation. The smoothness and efficiency of these chains make them ideal for use in applications where reducing operational noise is a key concern, such as in automotive engines.
In summary, the term “silent chain” applies to both the Morse and flat link chains, as they both use specific design features that reduce noise, making them quieter alternatives to roller chains in various mechanical systems.
