Springs play a crucial role in various mechanical systems as they store potential energy used in numerous operations. This article will delve into the specifics of standard compression springs and hourglass springs. Each type has its unique attributes, functions, and applications which we aim to clarify. For example, hourglass springs are often used in aeronautic landing gears attributed to their performance in handling load. We'll explore the reasons for this preference. In addition, we'll introduce some reputable manufacturers known for their quality hourglass springs, emphasizing the importance of superior components in successful engineering projects.
Comparison of Hourglass Springs vs Traditional
Standard compression springs, sometimes referred to as helical springs, are formed when coils of wire oppose compression. This type of spring typically takes on a cylindrical shape, and the length of the cylinder decreases when an external force is applied, causing energy to be stored. When the external force is eliminated, the energy that was formerly stored now gets converted into work. You can see an instance of its usage in the suspension systems of vehicles, where they utilize the spring's characteristic of absorbing shock to help keep a vehicle steady.
In contrast, hourglass springs have a narrowing at their midpoint, giving them a distinctive hourglass form. This shape enables them to retain and deliver greater amounts of energy compared to regular coil springs. However, creating these springs can be challenging due to their design. Despite the difficulty in manufacturing, engineers favour hourglass springs in scenarios where there's limited space. You can find instances of this spring's usage inside certain mechanical timers where its compactness is needed.
Common Use Cases of Hourglass Springs
Vibration Management : Hourglass springs are used in applications where high levels of vibration are present. Engines, for instance, create significant vibrations that can cause damage over time. The use of hourglass springs could reduce this damage by dampening these vibrations, possibly reducing the frequency of maintenance.
Heavy-duty Machinery : Hourglass springs are employed in machines that need high compression and recoil. The purpose of the hourglass spring's design is to store large amounts of energy and provide extended deflection. However, the use of hourglass springs in heavy-duty machinery depends on the correct load-bearing calculations made during the design phase to ensure operation safety.
Automotive Suspension : Hourglass springs have a role in the automotive industry, particularly in the suspension systems of vehicles. The structure of hourglass springs contributes to the control of the spring rate and helps to improve vehicle handling. For instance, trucks frequently transport heavy weights, which can considerably compress the suspension system. Standard compression springs could intensify the ride harshness in such circumstances. The unique shape of hourglass springs, however, allows for steady alterations in spring rate, leading to a smoother ride, even if handling heavy loads.
Hourglass Spring Manufacturers
Lee Spring : Lee Spring offers hourglass springs in numerous sizes and finishes. Their smaller hourglass springs are suited for applications with limited space providing a combination of strength and compact size.
Murphy & Read Spring Manufacturing Co. : Murphy & Read provides customized hourglass springs for different load needs. With a history dating back to 1917, they serve multiple industries. Their customized springs maintain a balanced load throughout the structure, allowing them to work effectively in applications with changing load requirements.
Spring Manufacturing Corporation : The Spring Manufacturing Corporation creates hourglass springs among other types. Depending on the application and design necessities, options include a more robust hourglass spring for high load-bearing applications, or a simpler design for lower load requirements. This customization is aimed at meeting the specific needs of each application.
The process of choosing between standard compression springs and hourglass springs requires a detailed assessment of your project needs. If your project involves managing high energy storage and considerable loads, hourglass springs are suitable, as their design supports these demands. On the other hand, for consistent or lower load requirements, standard compression springs are often the best choice. The reason behind this difference is the unique design of each spring type, with standard having a uniform diameter and hourglass being narrower in the middle. Both types find use in a range of sectors due to their specific properties, so your spring choice should match your particular project needs. When purchasing springs, it's essential to select manufacturers known for their quality and reliability.
