A disc spring is a conical shell which can be loaded along its axis either statically or dynamically.
Particular feature:
"Highest load in the smallest space"
Manufacture acc. to DIN 2093 and to works standard. Using all suitable non-galvanic surface treatments as well as in custom-sizes and from special materials (see our Materials overview list).

Disc spring stacks
On request, Mubea can deliver disc springs pre-assembled in stacks or on a guiding device.
Advantages:
Assembly is more efficient with pre-assembled stacks
Stack specific load - deflection diagrams (modern load testing machines can provide test loads up to 1000 kN)
Small load tolerances possible
100% load testing can be used to prevent incorrect stacking

DETAILS OF CONSTRUCTION
RINGFEDER® Friction Springs consist of a series of separate inner and outer rings with mating taper faces. Under the application of an axial load F the wedge action of the taper faces expands the outer rings and contracts the inner rings radially, allowing axial deflection.
An effective taper face i.e. one half inner ring and one half outer ring is defined as one element.
The rings are manufactured from high quality spring steel. They are rolled or turned, calibrated for size, hardened and tempered. The rings are then given a final dimensional check.
Before despatch, every complete spring is mounted according to the assembly drawing, several times block loaded and checked against diagram data.
CHARACTERISTICS OF RINGFEDER® FRICTION SPRINGS
1. Absorption/damping of high kinetic energies
2. Absorption of high kinetic energies at small component sizes
(e.g. overload protection)
3. Versatility in design
4. High spring work combined with low weight and volume
5. Overload-safe in blocked position
6. Characteristics independent of loading rate
7. Diagram independent of temperature
8. Parallel and series arrangement of springs
9. Force-travel Diagram

Advantages of Machined Springs:
Quality-reliability
Repeatability-predictability
Precision elasticity
Integration with the entire product
Reduction of separate assemblies
Precise spring rates
Reduction of complexity and cost
When Helical Products Company revolutionized coupling technology with the HELI-CAL Flexure Concept over 40 years ago, design engineers around the world discovered more reliable alternatives to traditional couplings, U-joints, and precision springs. Today, millions of HELI-CAL Flexures can be found in applications ranging from satellite instruments and scientific apparatus to conveyors and oil-field equipment.
The most demanding extension, compression, torsion, and lateral bending and translation spring applications can benefit from HELI-CAL Flexures because of their superior function and inherent versatility. HELI-CAL Flexures benefit overall system designs through enhanced functionality, increased precision and cost reduction as a result of true Value Engineering. Predictable and repeatable elastic performance is close at hand when one chooses HELI-CAL Flexures.
The final result is an elegant, single-piece component designed for the full extent of your workload characteristics in all operational modes, not just a single functional phase. The strengths fundamental to the original HELI-CAL Flexure Concept can expand your engineering horizons. Now you can dream!

SPIR'ATOR® Prestressed Spiral Springs
The SPIR'ATOR prestressed spiral spring is produced by reverse winding a NEG'ATOR on an arbor and enclosing it in a case. Rotational energy can be obtained from either the arbor or case or, when linear motion is required, through use of a pulley and cable attachement.
The unique design of this encapsulated spring yields a compact power source which operates with higher working stress and can provide more than twice as many revolutions as a conventional power spring in the same size case. With torque and deflection being equal, a SPIR'ATOR generally requires 20% less space than a power spring. Most importantly, this power package creates a low torque gradient.

The multiple and general-purpose functions of a helicoid are used to produce powerful springs of precision, accumulators of energy of the couplings...
The components upstream/downstream directly bordering are integrated to obtain a connection compact, cast solid, made safe.
The force of recall is restored with a constant value in compression, extension, torsion, in translation, alternatively but also simultaneously.
No the buckling of load, the whorls are reversed to avoid rotation in compression.
3 departures of whorls give more rigidity, improve the repeatability, safety. Even with a broken whorl, spring HELICAL remains operational.

Our speciality: small precision springs
with a weight of between 5/100ths of a gram and 300 grams.
Compression, traction, torsion – wire ranging from Ø 0.15 to 4.00 mm.
Production: 1 000 to 20 million units.
Very careful packing and delivery "Just in Time"..
Design assisted by a calculation software and prototyping service which provides the customer, within a very short period, with a small batch of industrial springs so that it can test their suitability for the intended application.
Compression springs
Wound into helicoidal, circular, cylindrical, conical or hyperbolical springs. The end coils may also be squared and ground.
|
|
A tightly coiled wound band of pre-hardened spring steel or stainless steel strip. When extended a constant force is exerted and this is maintained as the spring is allowed to close. The full force is effective until the spring is in the fully closed position.
This spring type derives its name from its ability to extend through its full working length while being maintained in any position by the same force. Constant force springs are available in a wide variety of sizes and the recent introduction of a purpose built plant ensures the price competitiveness of the smallest production run. Emmotts is one of the UK's most experienced manufacturers in this highly specialised field.

Flat Springs can take on a multitude of forms, from a simple leaf spring which operates in a single plane (as in a switch, for example) to a complex clip action which may operate in several planes at the same time.
Emmotts has built an enviable reputation in this field; which is amply demonstrated by their market share. The extensive range of standard tooling which Emmotts maintains often means their specialist tooling is not required for short run work . In conjunction with this , Emmotts has an `in-house' tooling facility to ensure the economical production of high volume work. Materials range from mild a stainless steel, through to copper and nicol alloys.
