Coupling Software from CicloSoft

Coupling Software

In a fast, accurate and user-friendly way, our coupling software performs the selection of rigid and flexible couplings that connect shafts of machinery.

The programming logic is developed according to the fundamentals of mechanical transmissions, combined with specific rules of the manufacturers, and with a database containing the technical specifications of each coupling size and type.

Select rigid and flexible couplings quickly and accurately. Our software merges mechanical expertise with a comprehensive database, transforming coupling selection into a remarkably intuitive process.

Coupling Types

Coupling Types

Power transmission couplings are basically manufactured in two different categories namely rigid and flexible.

Flexible couplings are those with a greater variety of types, but all are produced in a wide variety of sizes, capacities, and materials to suit any industrial application.

Flexible Couplings

  • Elastomeric Couplings

    • Spider Coupling or
    • Jaw Coupling
    • Rubber Disc Coupling
    • Bushed Pin Coupling
    • Tyre Coupling
  • Metallic Couplings

    • Spring Grid Coupling
    • Gear Coupling
    • Disc Coupling
    • Diaphragm Coupling
    • Roller Chain Coupling
  • Special Couplings

    • Helical Coupling or
    • Beam Coupling
    • Fluid Coupling
    • Oldham Coupling
  • Joints

    • Universal Joint
    • Double Cardan Joint
    • Homokinetic Joint or
    • Constant-Velocity Joint

Rigid Couplings

  • Rigid Flange Coupling
  • Sleeve Coupling or Muff Coupling
  • Clamp Coupling or Split-Muff Coupling

Sizing of the Coupling

For the selection of the appropriate coupling, the programming logic guides the software user step by step.

A design wizard helps the user through the data input process and provides explanations about the meaning of each design requirement and available configuration options.

Calculations and Analysis

Coupling CAD

In a highly organized, flexible and friendly environment, the user establishes the design requirements and the software performs all calculations and analysis necessary for sizing of the coupling:

  1. The user supplies characteristics of the driver and the driven machine, and determines the design parameters.


    • Driver Type
    • Driver Features
    • Type of Load
    • Available Power
    • Speed
    • Starting Torque
    • Braking

    Driven Machine

    • Application
    • Driven Machine Type
    • Type of Load
    • Required Power
    • Speed *
    • Required Torque
    • Overload Torque
    • Inertia Loads
  2. The user informs the operating conditions.


    • Operating Days/Week
    • Operating Hours/Day
    • Number of Starts/Hour
    • Start Up Characteristics
    • Reversibility


    • Ambient Temperature
    • Air Circulation
    • Chemically Aggressive Environments
  3. The software calculates the Service Factor.
  4. The software simulates the use of each type and size of coupling.
  5. The software analyzes the performance and suggests the most suitable couplings.
  6. The software generates a selection list with sorting and filtering capabilities.

Electric Motor Database

Since couplings are often assembled on shafts of industrial electric motors, the software has an extensive database containing data of electric motors from around the world.


  • 11 Types of Degree of Protection
  • 2880 Electric Motors


  • 11 Types of Enclosure
  • 3240 Electric Motors

Shaft-Hub Connection

Hole and Shaft CAD

For the assembly of the coupling, it is almost always necessary to machine the holes for the driver and driven shafts.

The coupling software automatically generates CAD drawings of the fixing elements, with all dimensions and tolerances.

  • Holes and Shaft Ends
  • Keys and Keyways
  • Locking Bushes
  • Other Clamping and Fixing Elements


  • ISO R773 - Parallel Key
  • DIN 6885-1 - Parallel Key
  • ANSI B17.1 - Parallel Key
  • Taper Lock Bushes


  • Diameters from 6 to 500 mm
  • Diameters from 6 to 500 mm
  • Diameters from 5/16 to 30 in
  • Metric Sizes - Imperial Sizes

Permissible Misalignments

Coupling Misalignment CAD

Flexible couplings allow some degree of misalignment between the driven and driving shafts.

The software shows data and drawings related to misalignment capacity of the coupling selected in three different directions:

  • Radial Misalignment
  • Axial Misalignment
  • Angular Misalignment

In some cases, misalignment limits can vary according to the operating speed of the coupling.

In other cases, misalignment limits can vary among themselves.

If so, the program plots the corresponding graphs:

  • Speed × Misalignments: Radial - Axial - Angular
  • Misalignment × Misalignment: Radial × Axial × Angular


Coupling Reports

Once the coupling has been selected, the software automatically generates all the engineering reports, datasheets, charts and CAD drawings in several standard paper sizes.

The display and printing of reports use a WYSIWYG (What You See Is What You Get) interface:

  • Report of Design Data
  • Assembly Drawing of the Coupling
  • Detail Drawing of Shafts and Hubs
  • Detail Drawing of Permissible Misalignments
  • Charts of Performance Curves

All of these documents can be easily customized, printed, emailed or exported to formats like:

  • PDF - DOC - XLS - JPG - GIF - TIF - PNG - FAX - etc.
