Once the primary function of the spring, whether push, pull, or twist, has been defined, the next step involves evaluating various types of springs and their configurations that can fulfill this function. The goal is to identify the spring type that not only performs effectively but also meets the space constraints and cost-efficiency requirements. This process involves considering different spring designs, such as helical compression springs for push functions, extension springs for pull functions, and helical torsion or spiral springs for twist functions. Each type has its own characteristics, such as deflection range and load capacity, which should be matched with the specific needs of the application to ensure optimal performance and economic feasibility.
At Ace Wire Spring & Form Co., we are well positioned to assist in this selection process. Our expertise in custom spring design and manufacturing allows us to provide tailored solutions that meet your precise requirements. With our advanced technology and engineering capabilities, we can offer a range of spring types and configurations, ensuring that you find the most effective and cost-efficient solution for your application.
Helical compression springs, spring washers, volute springs and beam springs all perform a push function. For large deflections, helical compression springs are most commonly chosen. For small deflections, spring washers are most common. Volute springs have high damping capacity and good resistance to buckling, but are not common because of relatively high manufacturing costs.
Beam springs are produced in a wide variety of shapes and can push or pull. Frequently, beam springs are required for functions in addition to the spring function, and sometimes are an integral element of a larger part.
Helical torsion and spiral spring configurations perform the twist function. Helical torsion springs are often used as a counterbalance for doors, lids or other mechanisms that rotate on a shaft. Spiral hairsprings have a low hysteries and are used in instruments and watches.
Brush springs received their name from their primary application of holding brushes against commutators in electric motors.
Power springs are often called clock or motor springs and are used to store energy for clocks, toys and other devices. Prestressed power springs are a special type of power spring that has a very high-energy storage capacity and is most commonly used on retractors for seat belts. Constant force springs provide an essentially constant torque over many revolutions.
Extension springs, drawbar spring assemblies and constant force springs, with helical extension springs being most common, perform the pull function. Drawbar spring assemblies are useful when a fixed stop is required. Constant force springs are similar to power springs; however, they are loaded by pull rather than twist.
Retaining rings and garter springs were especially developed to perform either push or pull. Retaining rings retain or locate parts in bearings and on shafts.
Garter springs are used primarily in oil seals.
Spring design often focuses on energy storage capacity, a crucial aspect for many mechanical applications. Springs are widely used in machines to absorb kinetic energy from moving components during deceleration and then release this stored energy during acceleration. This capability helps smooth out fluctuations and reduce peak loads, contributing to more stable and efficient operation. For instance, in clocks and toys, spring motors store and release energy to drive the mechanisms smoothly and consistently.
Torsion springs, another type of spring, are specifically designed to handle rotational forces. Their ability to store and release energy makes them ideal for applications such as window shades and garage doors. In these instances, torsion springs are used to control the movement of the shades or doors, ensuring they operate reliably and with minimal manual effort. This design function enables the effective management of mechanical energy, enhancing the performance and longevity of various devices and systems.
