Khodiyar Spring Industries is the major compression spring manufacturers in India. We offer best-quality, straight, cylindrically-shaped, tapering compression springs available in different diameters.
Compression Springs Overview
The compression springs are the open-coil helical spring that resists any compression force applied on it axially. Compression springs are usually coiled at a constant diameter, they can also be coiled in other shapes like – conical, barrel, hourglass, or a combination of these shapes.
The compression springs are winded over a rod or fitted inside a hole. When a load is applied, the spring gets compressed and pushes back to regain its original shape. These springs offer resistance to linear compressing forces.
Compression Spring Characteristics:
These are the most widely used type of springs. The main function of these springs is to oppose compression and when a compression force is applied on the spring the compression spring gets compressed and as soon as the compression force is removed the spring gets back to its original shape and form.
Compression Spring Measurements
We offer springs in different diameters like – Spring Steel 0.15 to 90 mm Wire Diameter, Square Wire Diameter, Square Wire Up to 20 mm Wire Diameter, Stainless Steel 0.15 to 60 mm Diameter, the spring material can be customized as per the client’s requirements.
Configurations
The straight springs are the most common compression springs. Mostly, the spring diameter remains constant for the whole length. The straight coil configuration is the standard coil type for stock compression spring types. The compression springs are of the following types - concave, conical, and convex type springs.
Solid height should be minimized.
High-duty springs are specified.
A tendency towards bulking should be reduced.
Accurate seating and uniform bearing pressure are needed
Key Parameters
The key parameters to take note are – inner diameter, outer diameter, wire diameter, free length, and solid height.
The free length of the compression spring is the overall length of the spring when the spring is in the unloaded position.
The solid height of the compression spring is when sufficient load is applied to the spring and all its coils are compressed to the maximum in a way that the adjacent coils touch each other. In this condition, the length of the compression spring is known as its solid height.
Spring Rate Or Stiffness
The spring rate is the change in load per unit deflection in pounds per inch (lb./in.) or Newton’s per millimeter (n/mm).
Unit Of Measures
Stress: The dimensions of the spring along with the load and the deflection requirements, determine the stresses in the spring. When the load is applied on the compression spring, the stress is highest at the surface of the spring. As the deflection occurs, the load varies in the spring causing a range of operating stress.
The spring life is dependent on the stress and the stress range. To obtain comparable life, the maximum stress must be lower and the stress range should be higher.
In case the stress range is low, the high-stress range can be used, if a static load is applied to the spring.
During installation, to refrain from any permanent damage the solid compression of the springs must be low enough and the stress at solid height must be high enough to permit presetting.
Service Life
For critical force-versus-deflection linearity, only the center 60-80% of the available deflection range should be employed and the last 15-20% of the range should be reserved for potential spring-end and adjacent coil-contact effects. These effects are not necessary for a wide range of spring applications.
The maximum deflection can be achieved without causing any damage to the spring when the spring is not subjected to shock loads, rapid cycling, temperature extremes, corrosion, or stress value above the recommended levels. Extended service life is attainable when the spring is statically loaded.
Tolerances
Our springs are manufactured to bear the commercial tolerances. Calculated spring rates and loads based on SMI geometric tolerances are subjected to a deviation of approximately +/- 10%.
Applications Of Compression Springs
Compression springs uses range from automobiles industry to large stamping presses, in major appliances, lawnmowers, and medical devices. Compression springs are also used in electronics and cell phones.
