FORM-FLEX METAL DISC FLEXIBLE COUPLINGS

Form-Flex couplings transmit torque while compensating for angular, parallel and axial misalignment between two connected shafts. Flexible disc couplings minimize the misalignment forces on the connected equipment.

The Basic Flex coupling consists of two hubs, a spacer and two flexible discs. The flex disc is an assembly of thin metal laminations. In figure shown below, flex disc holes A & C are bolted to the hub and holes B & D are bolted to the spacer. Torque is transmitted in direct tensions from A to B and from C to D through the flex disc. Misalignment is taken through bending in the link between the bolt holes.

Cooling Tower Drives

Form-Flex metal disc couplings are widely used in cooling fan drive applications. Form-Flex 4 bolt disc couplings offer more misalignment capacity than any competing metal disc design.

Formflex coupling diagram 2

For smaller towers up to about 100 inches DBSE, we offer steel and composite spacer tubing options. TrueTube composite torque tubes are lighter than steel and eliminate thermal growth and vibration problems.

Formflex coupling diagram 3

Form-Flex composite floating shaft couplings are recommended as a replacement for older multi-section drivelines. Composite couplings can span up to 240 inches without high maintenance centre support bearings.

Vertical Pump Drives

Formflex coupling diagram 4

Form-Flex floating shaft couplings are a costeffective, maintenace free alternative to cardan U-joints for vertical pump drivelines. Form-flex couplings are available with either steel or composite spacer tubing. Composite spacer tubing can reduce total cost by eliminating the need for bearings and support structures.

COUPLING/APPLICATION TYPES

COUPLING TYPE TYPICAL APPLICATIONS   SERIES
SINGLE
FLEX
Single flexing couplings compensate for angular and axial misalignment only. Single couplings should only be used in a three bearing system with a self-aligning bearing as shown in the illustration. Single couplings may also be used in pairs to support a clutch, transducer or other system component. These arrangements are double flexing and must be used with two fully supported shafts as described below. SINGLE FLEX AR

Spacer couplings are used to connect fully supported shafts with wider separations than can be reached with a close couple design. Spacer couplings allow room for installation and maintenance without moving the connected equipment. Shaft separations are generally in the range of 3 to 12 inches.
These couplings accommodate angular, parallel and axial misalignment.

COUPLINGS
Floating shaft couplings are spacer style couplings which are designed to connect widely separated shafts.The coupling spacers are fabricated. Both steel and TrueTube composite tubing options are available.

Semi-floating shaft couplings are a special single flex version of the floating shaft coupling. These may be used alone for some applications or in combination with floating shaft couplings and pillow block bearings to span long distances.

Composite floating shaft couplings should be considered as an alternative to mutiple span applications with centre bearings.

SELECTING AND ORDERING FORM-FLEX COUPLINGS

  1. Select correct service factor from the chart below.
  2. Calculate HP @ 100 or Design Torque (in lbs).
    HP @ 100  =  HP x service factor x 100
    coupling RPM

    OR
    Design Torque (in lbs)  =  63025 x HP x service factor
    coupling RPM

    OR
    Design Torque = Torque (in lbs) x Service Factor
  3. Compare this to the HP @ 100 column or the Rated Torque column.
  4. Check other limiting factors such as bores and overall dimensions.
  5. Standard Four or Six bolt couplings can be ordered as hubs and a centre assembly.
    All other couplings should be ordered by description.
SERVICE FACTOR TABLE
These service factors assume a smooth motor or turbine type driver. The adders listed for other driver types must be added to the service factor shown for the driven equipment.

Dynamic Balancing Recommendations

Balance Class Selection ChartUse this graph to determine the appropriate balance class based on coupling weight and operating speed. The balance classes listed on the graph are for equipment with average sensitivity to coupling unbalance. The user should determine how sensitive the equipment train is to coupling unbalance. Use one balance class higher if your system has higher than average sensitivity to unbalance. Use one balance class lower if your system has lower than average sensitivity to unbalance. Use this guide to check your coupling selection against the recommended balance class for your operating conditions.

The following factors should be considered when determining a machine's sensitivity to coupling unbalance.

  1. Shaft End Deflection: Machines having flexible shaft extensions are relatively sensitive to coupling unbalance.
  2. Bearing Load Due to Coupling Weight Relative To Total Bearing Load: Machines have lightly loaded bearings, bearings that are primarily loaded by the weight of the coupling or other overhung weight are relatively sensitive to coupling unbalance.
  3. Bearing, Bearing Support and Foundation Flexibility: Machines or systems with flexible foundations for supports for the rotating elements are relatively sensitive to coupling unbalance.
  4. System Natural Frequencies: Machines operating at or near natural frequencies are sensitive to coupling unbalance.
  5. Machine Separation: Systems having widely separated machines are relatively sensitive to coupling unbalance.
  6. Shaft Extension Relative to Bearing Span: Machines having a short bearing span relative to their shaft extensions are sensitive to static unbalance.

How Form-Flex Couplings Accommodate Misalignment

Diagram - Parallel OffsetDouble flexing metal disc couplings may be used to accommodate angular, parallel and axial misalignment. Single flexing couplings may only be used to accommodate angular and axial misalignment. A metal disc type coupling uses a double hinge effect through two flexible discs and spacer to compensate for parallel offset misalignment between shafts. Parallel misalignment imposes the same angular deflection (A) on each flex disc. Angular misalignment of either connected shaft (B) creates additional angular deflections which are added to the angular offset due to parallel misalignment. The total misalignment angle (C) at the flex disc is equal to the angular offset misalignment (B). The maximum misalignment angle (C) should never exceed the rated misalignment capacity of the coupling type being used. Machinery equipment changes in actual operation and over the life of the equipment. We recommend that the machinery misalignment be set as close to zero as possible when a coupling is installed. We recommend keeping the measured misalignment below 25% of the rated misalignment capacity of the coupling type used when the machinery is installed and aligned. The remaining coupling misalignment capacity will then be available to accommodate additional misalignment caused by foundation shifts, vibrations, thermal growth or other causes.

CLOSE COUPLE - AA SERIES 4 BOLT CLOSE COUPLED COUPLING

(General Use - Shorter Bolt Removal)

The AA series close coupling is made up of two hubs, a cast iron block type spacer and two sets of standard hardware. Stainless steel flex discs are standard. The AA accommodates close shaft separations when it is installed with the shafts extending through the flex discs into the centre of the coupling. The shaft diameter must be less than the flex disc I.D. listed in the dimensional table. This coupling is recommended when the bolt removal length (J) makes the AX coupling impractical. Special machined steel block spacers are also available in several sizes.

CLOSE COUPLE - AY SERIES 4 BOLT CLOSE COUPLED COUPLING

(Positioning Applications)

The AY series is specifically designed for positioning applications where a servo or stepper drive is C flange mounted and connects to a ball screw. The AY accommodates the small amounts of angular and parallel misalignment with an absolute minimum size package, zero backlash and high torsional stiffness. The AY is made up of two hubs, a steel spacer block, two stainless flex discs and AY hardware. The coupling must be installed as an assembled unit. The spacer is not service removable.

CLOSE COUPLE - BY SERIES 6 BOLT CLOSE COUPLED COUPLING

The BY series close coupling is a low cost replacement for gear or elastomeric couplings. It is ideal for use in low to moderate speed applications with motor or turbine drivers. The BY is an economical alternative to Axial Split spacer designs. The BY accommodates close shaft spacings by allowing the connected shafts to extend through the flex discs and spacer without restriction. The spacer is not service removable if the shaft gap is less than the D1 dimension shown. For shorter shaft spacings, the flex discs may still be replaced by removing the coupling bolts and shuttling the spacer from side to side.

CLOSE COUPLE - BA SERIES - 6 BOLT DESIGN &
DA SERIES-8 BOLT DESIGN AXIAL SPLIT SPACER COUPLINGS

Axial split spacer couplings are an ideal replacement for lubricated gear or grid couplings. Close shaft separations are met without requirements for extending shafts through hubs. The split spacer removes radially to allow removal of connected equipment. Flex discs may be replaced without disturbing the connected equipment. The axial split series features all steel contruction. Stainless steel flex discs are standard for the BA series. Both stainless and high strength alloy steel flex disc options are available with the DA series.

TRUE-TUBE™ COMPOSITE TORQUE TUBES

TrueTube composite tubes are high-strength, lightweight torque tubes for long span drive shafts. These tubes are filament wound carbon or glass fibre construction in an oven cured epoxy matrix. TrueTube composites offer the following advantages over steel tubing:

Lightweight Torque Tubes
Composite Torque Tubes

Longer Spans
TrueTube composite tubes have a higher stiffness to weight ratio than steel tubing. That increases the critical speed of the tubing and allows longer spans without centre bearings.

Light Weight
TrueTube drive shafts weigh up to 80% less than equivalent steel driveshafts. That means better balance and reduced vibration. Bearing life may be improved by minimising overhung weight.

Design Flexibility
TrueTube composite tubes may be custom designed to meet your requirements for torsional stiffness, critical speed or torque capacity. With TrueTube, a designer can tune torsional or lateral critical speeds out of a machine system.

All TrueTube products include an ultraviolet barrier that is wound into the structure of the tube before it is cured. This UV barrier eliminates the need for paints or other protective coatings and results in a smooth, durable finish that other composite tubes don’t offer. TrueTube products are cured in an enclosed oven to assure consistent strength and quality. Design data is shown below for standard series tubes. Standard series tubes are designed for maximum length at moderate torques. High torque designs are also available.

M SERIES - 4 BOLT MICRO COUPLINGS

Form-Flex M series microcouplings are a more compact and lighter design than traditional A Series couplings. They are free from backlash and their high torsional stiffness makes them ideally suited for small servo and tachometer drives. Aluminium hub construction meets low inertia requirements while the bolted assembly provides superior life when compared to riveted types.

Style MA Style MB Style MC
This coupling style is available in size 04 only. It features a machined spool type spacer. Custom length spacers are also available. This coupling style features a minimum length block spacer. Standard flanged hubs are supplied with the coupling. Style MB is a good, general use coupling. This style features the MB style minimum length spacer and an oversize bore capacity. The style MC provides the shortest coupling overall.

COOLING TOWER COUPLINGS

Cooling Tower Couplings photo 1

Designed specifically as a connection for cooling tower applications and other drives requiring long shaft spans. Form-Flex couplings with TrueTube composite tubing weigh less than half of its steel counterpart and can span shaft separations of up to 240 inches. They are easy to handle, install and maintain. TrueTube composites are extremely corrosion resistant and are custom designed to provide the optimum combination of torsional strength and lateral stiffness for cooling tower drive applications. TB Wood's proprietary composite flange design transmits torque reliably from the metal outboard hubs to the composite flange and into the TrueTube composite tube.

Cooling Tower Couplings photo 3

The traditional A5 design features all metal construction. It can be ordered to meet any custom spacer length. A wide variety of materials and finishes is available.

Cooling Tower Couplings photo 2

HD elastometric couplings and TrueTube composites are combined into a high misalignment, all composite coupling. These couplings are easy to install and align. Their high misalignment capacity makes them ideal for smaller, wood framed and fibreglass towers.

Please contact our technical sales department for further details.
