HELICAL BEAM SHAFT COUPLINGS

A single piece construction, zero backlash, constant velocity shaft coupling that simultaneously compensates for angular, parallel and skewed shaft misalignments.
Available in Stainless Steel or Aluminium as standard with both metric and imperial bores sizes stocked ready to be delivered.

Coil Width

HELICAL BEAM SHAFT COUPLINGS Coil Width

By varying the thickness of the coils, a Flexure can accommodate increasing amounts of torque and radial loads. The designer may specify torsional stiffness and compression spring rates independent of other factors.

Coil configuration

The individual performance capability of each Flexure is detemined by: coil width, inside diameter, number of coils, number of starts and material. Altering any one of these factors changes the performance characteristics of the “Flexure”. For example, the helical flexures illustrated display identical outside diameters and lengths. The effects of their variable characteristics - such as coil width, inside diameter, number of coils and starts are explained in the adjacent pictures.

Coil widths and inside diameters

As the coil width or inside diameter are changed such aspects as torque...angular misalignment (bending moment)...parallel offset (radial load)... torsional stiffness... and compression spring rate, are altered.

Number of coils

As the number of coils is changed, all of the characteristics except the torque capacity are affected.

Inside Diameter

HELICAL BEAM SHAFT COUPLINGS Inside Diameter

When the inside diameter changes, so does the torque capacity, torsional stiffness and axial spring rates.

Number of coil starts
  1. A single start design has one continuous coil.
  2. A double start has a second coil starting 180 degrees from the first.
  3. A triple start has three interwound coils, each spaced 120 degrees apart. When a multi-start helix is used (double or), the effect is to increase the torque capacity and torsional stiffness while reducing misalignment capabilities (angular and parallel).
Material

The proper material used in the manufacture of any helical flexure affects much more than just torque capacity. Factors such as elasticity, fatigue, corrosion resistance, mass, magnetic permeability, operating temperature, availability and cost also play important roles. High strength materials such as 17- 4PH CRES*, 15-5PH, C300, BETA C Titanium and 7075-T6 Aluminium, are just a few of the common choices for meeting design and performance needs.

Number of Coils

HELICAL BEAM SHAFT COUPLINGS Number of Coils

When the number of coils is changed the torque capability remains unaffected. All of the other characteristics change.

Attachments

In addition to being able to alter the characteristics of the flexure, you may have your attachment method integrated into the final product.

Typical attachment options might include:

  • integral clamps
  • set screws
  • set screw at one end and an integral clamp at the other
  • pins
  • slotted hubs
  • flanges
  • gears
  • removable caps
  • threaded bores with a wrench flat
  • or ... whatever your design requires
Number of Coil Starts

HELICAL BEAM SHAFT COUPLINGS Number of Coil Starts

Multiple, (typically two) helical beams provide high torsional stiffness. Shown: single, double and triple start.

Bore variety

Flexures may be engineered to include a variety of bore configurations. These variations include round, threaded, single or double-D, spline, keyway, tapered or ... your choice!

The flexible coil section of the coupling can be custom designed and manufactured to your specifications. Whether your considerations include high torque, angular or parallel misalignment, critical torsional stiffness, precise compression spring rates, or special end connections, chances are excellent that the flexure will meet or exceed your particular design requirements.

DESIGN BENEFITS OF THE FLEXURE

More than a coupling

The flexure concept brings enormous design flexibility to your applications. Depending on your needs, the flexure can serve as a flexible shaft coupling, universal joint, machined spring or your own specialised component.

Adaptability

The flexure's ability to accommodate various performance characteristics and its ability to integrate attachments directly enhances your freedom to design.

One-piece integrity

Not only does the flexure integrate multiple functions and parts into a single compact unit - no moving parts, no maintenance and no backlash - it can incorporate complex attachments.

State-of-the-art

High quality performance is achieved with magnetic or non-magnetic corrosion-resistant stainless steel, as well as aluminium alloys. Flexures are also successfully manufactured using various materials such as Delrin™ and titanium.

Operating Characteristic

Misalignment compensation

The flexing capactiy of the flexure can compensate for a variety of misalignments, including parallel, angular and skewed (three-dimensional misalignment. The Flexure solutions for these misalignment situations are shown in the adjacent photographs.

Angular

DESIGN BENEFITS OF THE FLEXURE - Angular Misalignment

Angular misalignment is the easiest form of misalignment for most couplings to accept, and thus one of the most practical applications of a flexible coupling. Allowing only enough space between coils to partially close the gap during bending, the flexure can accept an angular misalignment of 20 degrees or more (and even up to 90 degrees in special ujoint applications).

Optimised torque capacity

The basic requirement of a flexible coupling is to transmit torque loads without permanent distortion or damage and without imposing undue bending or radial load ,upon the driver or driven components. Once the working torque rating of a flexure coupling is established - based on misalignment and design criteria, material specifications and service factors supplied during the design process - its operational life is virtually unlimited.

Configurable torsional stiffness

Every flexible shaft coupling has some torsional flexibility. Torsional flexibility reflects the amount of twist in a system; torsional stiffness the degrees of resistance against twist. The flexure can be configured (with thicker coils, for example), to provide the exact amount of torsional flexibility required in an application.

DESIGN BENEFITS OF THE FLEXURE

Parallel

DESIGN BENEFITS OF THE FLEXURE - Parallel

Parallel misalignment is the most difficult form of misalignment for couplings to compensate for. It can also be the most damaging to shafts, bearings and motors. The flexure, through lateral displacement, transforms an application's parallel misalignment problems into angular displacement within the coupling. The centre coils of the flexure can become an intermediate shaft that can allow 10, 20 or 30 thousandths of an inch of parallel offset or more.

Skewed

DESIGN BENEFITS OF THE FLEXURE - Skewed

When shafts are not in the same plane (skewed), the flexure's abilities to compensate are the same as with either parallel or angular misalignment - but in the third dimension. A flexure designed with more coils in a series can compensate for as much three dimensional misalignment as your applications requires.

Smooth bearing loads

Bearing loads are primarily generated by a couplings natural resistance to bending, and can be very destructive forces to an apparatus and its rotational components. The flexure maintains a very constant radial and bending load at all points of rotation, providing exceptionally uniform bearing loads.

Constant velocity

In a rotating system, constact velocity refers to the relative rotational speed of the input and output shafts. In a constant velocity system the driven end of the coupling turns exactly the same rate as the driver end. When operating under a uniform load the flexure design provides constant velocity and alleviates:

  • Backlash: the flexure has zero backlash, because of its one-piece construction.
  • Angular misalignment, which can induce large fluctuations in rotational velocity in many coupling designs, is corrected by the flexure's constant spring rate at all points of rotation.
  • Torsional variations, which can induce differences in hub-to-hub velocity when subjected to dynamic loading, are minimal in steady-state applications of the flexure.
  • Concentricity, when there is a lack of it - particularly in the case of couplings with backlash or where production variation is difficult to prevent - the flexure's one-piece integrity minimises sinusoidal variations.

DS SERIES, ALUMINIUM

  • High torsional stiffness
  • Low radial loads
  • Parallel misalignment capability
  • Low inertia

The DS Series was designed for today’s high performance motion control systems. This Series incorporates two helical beams in each of two separate Heli-Cal Flexures, combining greater end-to-end rotational accuracy with radial flexibility in one design. Available only with integral clamp attachments, the DS Series provides the high torsional stiffness and low inertia necessary for positioning devices, servo motors and lead screws.

The DS Series also provides you with substantial .010-inch parallel offset capability, reducing the need for high-precision alignment during assembly operations. It’s your ticket to greater system accuracy and reliability. Available only in 7075-T6 aluminium.

Notes
  1. Bore Sizes are placed into the part number with leading dashes after the basic model number.
    Standard bore dimensions are noted in the 32nds of an inch, such as 8/32 or 3/32in. The respective dash numbers would be -8 and -3. Any bore dimensions that are not an integer number of 32nds should be converted to their millimeter equivalent with "mm" after the numerical designation, e.g. .315in. = 8mm.
  2. When specifying part numbers, metric bore diameters are specified without trailing zero after the decimal point, e.g. .315in. = 8.00mm, but the bore designation is -8mm. This is only for simplicity in ordering and does not affect the tolerances of the actual bore dimensions. Bore tolerances are specified on the Engineering Proposal Form at the end of the catalogue.
  3. Manufacturing dimensional tolerances unless otherwise specified are:
fracx.xxx.xxxangle
±1/64±0.010±0.005±2°
fracx.xx.xxangle
±0.5±0.25±0.15±2°
  1. A complete line of speciality OEM and end user products is available; please refer to the Engineering Proposal and/or contact our Engineering Department.
  2. A chart showing our standard line of instrumentation couplings with precision bore tolerancing is available upon request.
  3. All parts are available with metric or inch fasteners to be compatible with the fastener system used in your designs.
  4. Bore diameters less than minimum listed may be possible for one bore only. Contact our Engineering Department.

X-SERIES, RADIAL (CROSS) SLOT, FLEXIBLE COUPLINGS

  • Torsionally Stiff
  • Zero Backlash
  • No Maintenance

The new X-Series is a high performance, easy to use, durable, full featured, radial (cross) slot flexible coupling with high torque capacity and exceptional torsional stiffness. It is offered in six different outside diameters and a wide range of bore sizes. It features the reliable, user friendly, integral clamp attachment.

Design Considerations

The integral clamp fasteners are located inline, on either side of the radial-slot flexing element. This provides the easiest assembly for most applications, where just moving the hex wrench across the flexing element is all it takes to tighten both fasteners.

Along with high torsional stiffness and torque capacity, the X-Series couplings are completely machined from a solid piece of material. This one piece integrity ensures that there is never a worry about wear, looseness and backlash, as found in multi-piece assemblies.

To make component assembly as easy and compact as possible, the X-Series features a bore relief. This allows shafts to be inserted into the centre of the coupling without affecting the misalignment capability of the coupling. By making the centre flexible section with a slightly larger ID than either shaft size, the shafts can be inserted into this area without contacting the flexible element ID during operation. 7075-T6 aluminium is the material of choice for the X-Series.

Test results

X-Series couplings have been subjected to rigorous reliability testing. During durablility tests, couplings are subjected to parallel offsets of up to five times their rated value and tested to failure. The XSeries couplings were tested for tens of millions of cycles at these exaggerated offsets and exhibited an exceptional premium performance capability.

In brief

Available in six outside diameter sizes, from 15mm to 50mm and any bore combination between the listed minimum and maximum. Couplings can be ordered with bores that are either millimetre, inch or combination of the two.
