Parallel connection of leg springs, torsion springs, torsion springs - the double leg spring

The parallel connection of the leg spring, torsion spring, torsion spring

When leg springs, torsion springs, torsion springs are connected in parallel, the leg springs are connected next to each other.
If the legs connected in parallel experience If leg springs have a torque M (M1, M2, M3 ... MX) in Newton millimeters (Nmm) and a rotation angle Alpha (Alpha1, Alpha1, Alpha3 ... AlphaX) in ground mass (rad) or angle degrees (°), then the same rotation winding Alpha = Alpha1 = Alpha2 = Alpha3 = ... AlphaX acts on the leg springs connected in parallel.
However, the introduced torque M in (Nmm) is divided between the individual leg springs, depending on the stiffness of the individual leg springs, as M = M1 + M2 + M3 + ... MX.
Torque M in (Nmm) when the leg springs are connected in parallel M = M1 + M2 + M3 + ... MXwith Alpha = Alpha1 = Alpha2 = Alpha3 = ... AlphaX and Alpha = M/CM Angle of rotation in (rad) or (°) when connected in parallel Alpha = Alpha1 = Alpha2 = Alpha3 = ... AlphaX Torsion spring rate / Torsional spring stiffness CM in (Nmm/rad) or (Nmm/°) when connected in parallel M = CM*Alpha = CM1*Alpha1 + CM2*Alpha2 + CM3*Alpha3 + ... + CMX*AlphaXAlpha = Alpha1 = Alpha2 = Alpha3 = ... AlphaX and M = CM*Alpha or CM = CM1 + CM2 + CM3 + ... + CMX M in (Nmm); CM in (Nmm/rad) or in (Nmm/°); Alpha in (rad) radians or (°) degrees of angle


The double leg spring - a prominent representative and a special case of the parallel connection of leg spring, torsion spring, torsion spring

The double leg spring is a special case of the parallel connection of leg spring, torsion spring, torsion spring.
The double leg spring is two individual leg springs connected in parallel with the same stiffness or spring rate. Both spring bodies of the double leg spring are structurally identical, this means that the number of turns n and the turn diameter Dm of both individual leg springs are the same size (ns = n1 = n2) and (Dms = Dm1 = Dm2). The torque Md (Nmm) acting on the double leg spring and the angle of rotation Alphad (rad) or (°) act on both individual leg springs.
This results in the following relationship:
Torque Md in (Nmm): Md = M1 + M2; Torsion Alphad in (rad) or (°): Alphad = Alpha1 = Alpha2 = Alphas
Torque Md in (Nmm) for the double leg spring Md = M1 + M2with Alphad = Alpha1 = Alpha2 and Alphad = Md/CMd Torsion angle Alphad in (rad) or (°) for the double leg spring Alphad = Alpha1 = Alpha2 Torsion spring rate / torsion spring stiffness CMd in (Nmm/rad) or (Nmm/°) for the double leg spring Md = CMd*Alphad = CM1*Alpha1 + CM2*Alpha2Alphad = Alpha1 = Alpha2 = Alphas and Md = CMd*Alphad or CMd = CM1 + CM2 Md in (Nmm); CMd in (Nmm/rad) or in (Nmm/°); Alphad in (rad) radiansss or (°) angle degree
Md = CM*Alpha = CM1*Alphas + CM2*Alphaswith Alphad = Alpha1 = Alpha2 or Alphas = Alpha1 = Alpha2 and Alphad = Md/CMd CMd = CM1 + CM2with CM1 = CM2 = CMs results CMd = 2*CMs Md = 2*CMs*Alphas Md = CMd*Alphadwith CMd = 2*CMs and Alphad = Alpha Ms = (1/2) *CMd*Alphawith CMs = CMd/2 and Alphas = Alphad = Alpha Ms = CMs*Alphawith CMs = CMd/2 and Alphas = Alphad = Alpha Md in (Nmm) torque of the double leg spring
CMd in (Nmm/rad) or in (Nmm/°) stiffness or spring rate of the double leg spring
Alphad in (rad) radian measure or (°) angular degree of twist angle of the double leg spring
Ms in (Nmm) torque of the individual leg spring
CMs in (Nmm/rad) or in (Nmm/°) stiffness or spring rate of the individual leg spring
Alphas in (rad) radians or (°) angle of rotation of the individual leg spring
From this it can be deduced that the double leg spring has twice the stiffness or spring rate compared to the two individual leg springs.
The angle of rotation Alphad is the same for the double leg spring and both individual leg springs.
The torque on the double leg spring is divided equally between both individual leg springs.


Spring formulas for a single leg spring:

Torque M in (Nmm): M (Nmm) = CM * Alpha CM in (Nmm/rad); Alpha in (rad)
Rotation angle Alpha in (rad) radians: Alpha (rad) = M / Alpha M in ( Nmm); Alpha in (rad)
Torsional spring stiffness / torsion spring rate / spring rate / stiffness CM in (Nmm/rad): CM (Nmm/rad) = M / Alpha M in (Nmm); Alpha in (rad)

The torsion spring:
Cylindrical torsion springs or also known as torsion springs, helical torsion springs are widely used and versatile machine elements components in the world of mechanics and spring technology.
The structure of a cylindrical torsion spring consists of a wire that is wound in a helical shape around a central axis in even turns.

torsion springs are used to absorb and release a rotating movement, a torque or a force and to guide the movement of the legs.
torsion springs are characterized by the ability to absorb and release deflections, forces or torques around a rotation axis and to guide the rotational movement.
torsion springs usually have a cylindrical spring body on which two legs are arranged.
The legs can be arranged tangentially, radially or axially, whereby each leg can have a different arrangement. Different spring end shapes can be attached to the end of the two legs, e.g. straight leg, hook shape, eyelet shape, round or square.
The terms "torsion spring", "torsion spring" and "torsion spring" refer to the same component.

The double torsion spring:
Double torsion springs, double torsion springs and double torsion springs are widely used and versatile machine elements in the world of mechanics and spring technology.
The structure of a double torsion spring consists of a wire that is wound in a helical shape in even turns to form two separate spring bodies. The two spring bodies are connected by a wire, which is usually designed as a U-shaped web.
The legs or spring ends of the double torsion springs are usually attached to the outside of the respective spring body. The force or torque is introduced either via the U-shaped web or via the legs. The double torsion spring is usually guided via a mandrel, axle or bolt.

The wire bent part:
In practical use, standardized wire bent parts such as spring rings, snap rings, retaining rings, clips, pins, etc. are found. A paper clip or a staple clip also belongs to the wire bent parts, wire form springs and bent parts.
However, in practical use, non-standardized, individual, application-specific designed wire bent parts are mostly used. Wire form springs and bent parts are used.
The focus is on the function of the component: e.g. securing, protecting, holding, positioning, clamping or springing.
Wire form springs, wire form springs and bent parts made of spring steel wire are important components in various industries and applications. Bent wire parts are special machine elements that usually have springy properties.
They are made into a specific shape by bending wire and offer a variety of advantages in terms of flexibility, cost-effectiveness and functionality.
