Cast iron flywheels are essential components in many machines and engines. They are used to help store rotational energy, maintain speed, and provide smooth operation of mechanical parts. They come in a variety of shapes and sizes, each designed for its own purpose.
When choosing a cast iron flywheel for your application, you need to consider the size, weight, material composition, and type of flywheel required for the operation and some additional features you may require.
Let’s take a look at the four most common types of cast iron flywheels to get a better understanding of their applications.
Four Most Common Types of Cast Iron Flywheels
Following are four types of cast iron flywheels. Let’s know about them in detail.
Solid Disc Flywheel
The solid disc flywheel is the most basic type of cast iron flywheel and is used primarily in flywheel thresher systems. It is made from a disc and a flywheel hub.
The rimmed flywheel consists of three components: the rim, arms, and hub. This type of flywheel explodes with low rotatory speed as compared to the first type with the same diameter and weight.
As its name implies, the high-velocity flywheel is designed for applications requiring high rotational speeds. The velocity of these flywheels ranges between 30000 rpm to 80000 rpm but can be adjusted to 10000. These are expensive and lightweight as compared to low-velocity flywheels.
The low-velocity flywheel is designed specifically for applications where lower speeds are required but still want some sort of rotational inertia stored within the system. Their angular velocity is 10,000 rpm. They do not have magnetic levitation bearings and are heavy according to size and weight. They require high maintenance and are less expensive than high-velocity flywheels.
Uses of Cast Iron Flywheel
Cast iron flywheels provide many benefits when it comes to the operation of an engine or machine. They act as shock absorbers that absorb sudden spikes in torque caused by acceleration or deceleration, helping to ensure smooth operation without damaging other components.
Also, they help regulate engine speed by absorbing energy during acceleration and then releasing it during deceleration. This helps stabilize engine speed, making it easier to control while providing improved fuel efficiency and reduced emissions due to smoother operation.
They act as momentum wheels that provide inertia when starting an engine so that it will start quickly without stalling out or lurching forward suddenly when the throttle is applied.
The various types of cast iron flywheels offer different advantages depending on your needs or application requirements. Solid disc flywheels are best for low-power applications where durability and simplicity are desired. In contrast, rimmed ones are best for higher power outputs due to their increased surface area and storage capacity. High-velocity ones offer higher spins with less weight, while low-velocity ones provide slower spins with more storage capacity; there’s something for everyone! No matter what you need from your engine system, there’s likely an ideal cast iron flywheel out there for you!
