Compression Springs:
Compression springs, also known as coil springs, are mechanical components with an open-coiled helical design. These springs efficiently store and release energy when subjected to compressive forces. Their primary function is to absorb shock, maintain force equilibrium, and provide resilience in various mechanical systems.
How Do They Work?
When a compressive load is applied axially, these helical springs resist the force by compressing or squeezing. As the load is removed, the stored potential energy is transformed into kinetic energy, causing the spring to return to its original, uncompressed state.
How Do They Work?
Compression springs find applications across diverse industries due to their versatility. Here are some common uses:
- Landing gear
- Flight controls
- Actuators
- Suspension systems
- Clutches
- Brakes
- Gear shifts
- Washing machines
- Refrigerators
- Presses
- Lathes
- Conveyor systems
- CNC machines
- Assembly machines
- Surgical instruments
- Dental tools
- Orthopaedic devices
- Valve and pump systems.
Types of Compression Springs:
Compression springs come in various shapes and sizes to meet specific requirements. Here are five common types:
- Outward bulging or dome shape
- Ideal for applications requiring high force
- Used in medical equipment, electrical switches, and precision instruments
- Narrow in the middle, widening towards the ends.
- Suitable for tight tolerance applications
- Helps limit variance in spring deflection.
- Cone-shaped design with gradually increasing diameter
- Efficient energy storage and compressive force application
Torsion Springs:
Torsion springs are mechanical springs designed to store and release rotational energy or torque when twisted around their axis. Despite their name, these springs primarily endure bending stress rather than pure torsional forces.
How Do They Work?
- Helical Design: Torsion springs consist of wire wound in a spiral shape.
- Twisting Action: When twisted, they exert torque in the opposite direction.
- Energy Storage: As the spring is twisted, it stores potential energy.
- Release Mechanism: Upon releasing the torque, the spring returns to its original position1
Applications Across Industries:
Torsion springs play a crucial role in various applications:
- Clothespins: These springs operate clothespins, ensuring a secure grip.
- Mousetraps: Traditional spring-loaded-bar mousetraps utilize torsion springs.
- Garage Doors: Large coiled torsion springs counterbalance the weight of garage doors.
- Trunk (Boot) Covers: Some sedans use torsion springs to assist in opening trunk covers.
Key Configurations:
Wind Direction:
- Torsion springs are wound either clockwise or counter-clockwise.
- Loads should be applied in the direction of the wind.
Leg Arrangement:
- Leg angle represents the circular difference of the spring ends when it has no potential energy (values range from 0° to 360°).
- Leg orientation determines the positioning of the legs relative to each other and the spring axis.
- Leg length affects the load needed to store energy in the spring.
- Leg style refers to the various methods of attaching legs to an object.
Double Torsion Springs:
- These consist of two torsion springs:
- One wound clockwise.
- One wound counter-clockwise.
- Each has an independent leg but is intermediated by an unwound section.
- The total torque available is the sum of both springs’ torques.
Specifications to Consider:
Dimensions:
- Inner Diameter: For slipping over a mandrel with sufficient clearance.
- Outer Diameter: For fitting into a circular hole with exterior clearance.
Materials:
- Common materials include music wire, hard drawn steel, stainless steel, and phosphor bronze.
Finishes:
- Choose appropriate finishes based on environmental conditions and corrosion resistance.
Extension Springs:
Extension springs, also known as tension springs, are essential mechanical components that store energy when stretched or extended. They work by resisting axial forces and returning to their original length when the load is removed.
Design Considerations:
When designing or selecting extension springs, consider the following factors:
Spring Shape and End Type:
- The most common shape is cylindrical with hooks on both ends.
- Other shapes include swivel hooks and straight cut drawbars.
- Remember that stress is highest at the ends of hooked springs, where they are first bent to form the hooks.
Number of Coils:
- The number of coils affects the spring’s behaviour.
- Adding springs in series increases travel, while adding them in parallel increases force.
Preload and Allowable Stress:
- Preload ensures the spring operates within its intended range.
- Avoid loading past the yield strength to maintain spring behaviour and longevity.
Spring Index:
- The ratio of mean diameter to wire diameter.
- Influences spring performance and stress distribution.
Applications Across Industries:
Extension springs find use in various applications:
- Automotive: Hood latches, trunk lids, and seat mechanisms.
- Industrial Machinery: Conveyor systems, garage doors, and agricultural equipment.
- Consumer Goods: Trampolines, garage door openers, and toys.
Calculating Spring Parameters:
- Spring Rate (Constant): Calculated based on mean diameter, wire diameter, and modulus.
- Body-Wire Stress: Consider applied load, number of coils, and spring geometry.
Safety and Failure Considerations:
- Extension springs fail differently from compression springs.
- When an extension spring fails, components can separate, potentially causing accidents.
- Always operate extension springs within their intended range to ensure safety.
Wireforms:
Wireforms are intricate and versatile shapes crafted from metallic wire. While springs constitute a type of wireform, it’s crucial to recognize that not all wireforms are springs. They differ in form, function, and may vastly vary in application.
Wireforms Beyond Springs
- Wireforms encompass a broader category:
- Retainers: Wireforms often serve as clips, pins, or retainers.
- Simple Beams: Some wireforms act as simple beams, offering return force when bent or twisted.
Manufacturing Process
