What are chain drives? In this article, we are going to learn a core concept of chain drives, definition, meaning, different types of chain drive, advantages, disadvantages, applications, etc.
So, what is a chain drive? Let’s learn from the basics.
Do you know there are a plethora of ways by which you can harness energy to produce energy or motion?
In mechanical engineering, there are different kinds of equipment that are quite effective and help to attain effective energy.
In Layman’s language chain drives or sprockets are simplistic components that can nurture the rotational motion for generating energy.
For example, our bike has a sprocket that is attached to a chain that provides rotational motion to the wheels, due to which we are able to move our bike.
Here, we are providing hands on knowledge about the chain drives and all the related information that can come handy in understanding the importance of these efficient mechanical components.
Let’s delve into the information and start with the general definition of the chain drive.
Chain drives are the components that are equipped with an endless series of chain links that are meshed with toothed sprockets.
Sprockets or sprocket wheels are the toothed wheels on which the chains got lodged. These wheels are just like spur gears.
The effective functionality of these chain drives is to transmit power and motion from shafts.
These are mostly used in those machines which have smaller distances between the center of the shafts such as,
As we know that chain drives are equipped with numerous chain links which are meshed together with toothed sprockets.
These chain drives are especially used for three essential function:
The foremost use of these chain drives is in different kinds of industries.
It is widely used at such places where there is a need for,
These chain drives can be also used directly or indirectly by attaching,
Chain drives are usually used for transmitting power from one part to another.
Specifically, these are helpful for transferring torque and speed with the help of sprockets and linked chains.
It helps in regulating the driver’s output speed by changing gear ratios between the sprocket and the driver.
Apart from all the usages of chain drives the massive use of this component is also as a synchronizer or maintaining the time movements.
These are specifically used in different industrial combustion engines that use these chain drives for regulation valve timing.
Chain drives can be understood by getting an idea of all the effective terms associated with this.
There are some of the important terms that are quite important. Without the knowledge of these terms, it is quite hard to understand the kinematics and working of chain drives.
The following are some of the basic terms associated with chain drives:
The distance between the hinge center of the link and the corresponding center of the hinge center of the adjacent link is known as the pitch of the chain.
This is important to understand in a way that helps in understanding the different parameters.
Sprocket is the component on which the chain is wrapped around.
These two are the basic terms that come handy while understanding the kinematics of chain drive.
While understanding about chain drives it is mandatory to get an idea about its different types.
Though the whole drive is a separate component which consists of chains and sprocket.
Here we have to understand the importance of chains as these chain drives are classified on the basis of chains only:
These chains are further divided as per their usage. These are classified in three groups.
Here, we are discussing the above types of chains with their subdivided classifications:
Hoisting and hauling chains are widely used for industrial purposes.
Hoisting and hauling chains are further subdivided into three types. They are as follows:
Oval link chain
The chain with oval links are those in which the main design is oval in shape. In these the joints are welded to each other.
Square link chain
As the name suggests these chains are equipped with square-shaped links. These kinds of chains are basically used in dredges, hoists, and cranes.
Stud link chain
Stud link chain means the chain with oval or square shape with study which helps the chain to make more strengthen.
The conveyor chains are typically used for conveying or elevating the materials.
These are manufactured of malleable cast iron that generates below level smooth running qualities.
These are mainly used in those places where there is a need of slow speed material shifting.
Basically, there are two types of conveyor chains:
The power transmitting chains are the most important and widely used chain types that are used specifically for the transmission of power.
The distance between the center of the shafts is minimal. These chains need efficient lubrication.
Basically, there are three types of power transmitting chains. They are as follows:
Block chains are the type of power transmitting chains that are used in the pre-stage of the power transmission development.
Bush roller chain
When there is a need for optimally strong and simplistic chains, these kinds of chains are used.
The bush roller chains are equipped with,
In these, a pin passes through the bush which is attached to the roller between both sides of the chain.
These rollers are mainly free to rotate which protects the sprocket wheel effectively.
Inverted tooth or silent chain.
While using chains the factor of producing excessive noise is the main reason for wear and tear.
It is specially designed to cater to all the disadvantages associated with motion-oriented defects such as stretching, noise, and other ill effects.
The Pitch of the chain increases when there is stretching action.
The unavailability of relative sliding action makes it perfect for the rugged use. if these chains are effectively lubricated then you can expect maximum durability and service.
With these chains, one can easily attain quieter working and smooth movement.
There are numerous advantages that are provided by chain drives. Here are some of the following:
The core applications of chain drive are vivid. Here are some of the essential applications of chain drives:
With these being said the use of chain drive is vivid. The understanding of chain drive and it’s all aspects lead to having better knowledge.
This article provides a holistic view of all the aspects and generates a deep sense of knowledge about chain drive. Though the study of chain drives can be elaborated further.
