Convincing advantages

• the belt is part of a modular designconsiting of the ATN timing belt, fasteningelements, the ATN timing belt lock and flights/profiles

• variable profile pitches with a high accuracy

• Application of various profile materials is possible(plastics, metal, ceramics, ...)

• high shearing forces

• fast and easy profile change whenthe products to be transported are changed or theprofiles are worn

• no belt deinstallation for profile changes

• Alternative to a chain with all advantages of atiming belt

• Self-alignment of the profiles during installation

• Application of standard pulleys

• high optical quality

• various fastening possibilities

• Cost effective for the user:

- Standard belt with a high availability andvariability

- short machine shut-down times for profilechanges

- low test costs because ofchangeability of the profiles (prototypes)

- low spare parts and mounting costs

ATN - the transport timing belt with multiplepossibilities

BRECO Antriebstechnik Breher GmbH & Co., themanufacturer of the well-known BRECO® andBRECOFLEX® TIMING BELTS, is the most innovativeproducer in the field of timing belt technology.Polyurethane for the belt body and tension membersmade of steel, used for all BRECO® and BRECOFLEX®

TIMING BELTS, form the basis for a high-quality andfunctionally reliable product.

The ATN timing belt is especially designed forapplication in the transport technology. Theexchangeable profile fastening system in the belttooth permits fast fitting and replacement of theflights individually manufactured for the conveyingapplication concerned.

This flexibility provides a great variety of applicationpossibilities, not to be realised up to now, comparedto other profile fastening systems, as e.g. welding. Ifrequired, it is possible to convey different types ofgoods in one transport system using the same timing belt, butequipped with different profiles.

Shapes for the profile fastenting

Shapes to accommodate profile fastenings (insetparts) are designed in each tooth as standard for allATN timing belts. For this reason, the extrudedlongitudinal spacing of the shapes corresponds withthe timing belt pitch.

ATN10 / ATN10K6: 10 mmATN12.7 / ATN12.7K6: 12,7 mm

ATN20 / ATNS20: 20 mm

When adhering to particular conditions, largerlongitudinal spaces can be extruded, i.e. only in eachn tooth is a shape present.Check the following rules, if a shape is only requiredin each n tooth:

ATN10 / ATN10K6: 120 / n integerATN12.7 / ATN12.7K6: 96 / n integer

ATN20 / ATNS20: 60 / n integer

Example:ATN 10Shape only in each third tooth:120 / 3 = 40 integer

Please ask for the minimum purchase quantity forthese special versions.

TIMING BELTSATN timing belt lock

ATN timing belt lock

The timing belt lock especially developed for the ATNis a detachable connection and is used where theATN timing belt can, for constructional reasons, onlybe connected endless once it is fitted into thetransport line.

Connection elements made of high tensile polyamideand plates made of spring band steel guarantee areliable connection of the belt ends. The user canselect between three or two different versionsdepending on the belt type.

For lock version „C“ (Connection) for the timing beltsATN 10, ATN 12.7, ATN 10 K6,ATN 12.7 K6, the back plates are screwed on the beltbacks. The belt is 0.9 mm higher in the lock area thanthe standard thickness of the ATN timing belts in thementioned pitches due to the plates.

With the newly offered lock design „DC“ (DeepConnection) the thickness of the timing belt with thepitch 10 and 12.7 is adapted so that the back of thebelt and the plates are flush.

The design „DC-PRO“ provides the possibility tofasten profiles in the lock area without the need tochange the profile geometries.

An adaption of the back thickness is not necessarywith the ATN 20 and ATNS 20. The geometry of theback of the belt is adapted through the plate heightin the lock area.

The inset parts, screws, back plates and theconnection elements for the profile assembly areoffered by us as standard according to the lockdesign.

Ordering information

When ordering an ATN timing belt with lock connection, the lock is notautomatically included. The lock must be ordered with the correspondingordering code in addition to the ATN timing belt order.

The lock is added to the timing belt and not preassembled as standard. If apreassembly is required, this must also be stated with the order. The orderaddition „assembled“ must be added to the belt designation and to the lockdesignation.

For the design „DC-PRO“ the addition „PRO“ must only be added to the lockdesignation. Special elements are required for the profile installation for the DC-PRO design. We deliver these elements and the respective screws in variouslengths to fasten 5 profiles as standard.

Attention:For the lock design „DC“ and DC-PRO“ inset parts adapted to thetiming belts ATN 10 and ATN 12.7 to fasten profiles are also required outside thelock area. Please take the ordering examples in chapter „Profile fastening“ intoaccount.

TIMING BELTS

TIMING BELTSATN profiles

ATN adapter

Two possibilities to fasten the ATN profiles areoffered. The profile can be directly screwed to theback of the belt or pushed on an adapter. Pushingcan be required when the profile shape does notallow the profile to be screwed on.

The adapters manufactured by us guarantee areliable fastening with the respective profiles. Thismanner allows the profiles to be easily and quicklychanged.

It is not required to replace inset parts because theadapters need not to be loosened during profilechanges. Furthermore, longer screws are not requiredfor fastening different profile heights.

TIMING BELTS


The ATN system is especially designed for application in transport technology. Use guide rails to ensure thetiming belt is reliable guided (see picture below).

We provide guide rails with and without guide channels for ATN timing belts without guide V-groove. Vers-ions G, GC, F and FC can be used.

For the BRECO® TIMING BELTS ATN 10 K6 and ATN 12.7 K6 guide rails version K6, K6C, ATN K6 and ATN K6Care available.

MaterialLow- pressure polyethylene is used as material. This material has a low friction coefficient and is wearresistant. The sliding friction value between standard polyurethane and low-pressure polyethylene is µ ≈ 0.3.

The C profile is made of zinc plated sheet steel. The cut-out is intended for fastening screws. The C profile hasno bore holes.

Mounting instructionDue to the relatively high-temperature expansion of the sliding material, provide expansion gaps in the railstructure. Approximative formula for the linear expansion of low-pressure polyethylene:

2mm/10°C temperature difference over 1000 mm of length.

Basis of calculation

Additional inertial force when changing into and out of the circular movement

Each profile fastened to the belt is subject to a very high acceleration when changing from the linear movement intoor out of the circular movement. This is due to the different rotational speeds v

ro t of timing belt and profiles in the

angle of wrap. While the speed v in the neutrale belt fibre does not change, even during rotation, vrot

=vlin

, the profileitself in this area is subject to a notably higher speed than in the linear movement, v

ro tProfile>v

linProfile. The distance of the

centre of gravity of the profile hSP

from the neutrale fibre and the mass of the profile mP

are of decisive importance.With these and further parameters the admissible height of the centre of gravity of the profile can be determinedusing the diagrams on page 40.

If the product to be transported additionally runs around the pulley and the guide rollers, the product, too, is subjectto the high acceleration. In this case, use the „ATN-CONNECT“ calculation program to calculate the profile jointresistance.

Load at the ATN profile joint

Pushing force in the linear movement of the productto be transported

If the product to be transported (TG) is pushed by theprofiles and it slides on an anti-friction rail or similar, thepushing force is mainly the friction force. In cycleoperation the inertial force of the product to betransported is also to be taken into account.

Centrifugal force

Here, the occurring centrifugal forces are considered.The portion of the product to be transported must onlybe considered when the TG is actually circling. Thecentrifugal force is generally low compared to the inertialforce.

Pre-tension force of the screw connection

The pre-tension force of the screw connection is a directpart of the tensile load on the inseert parts. For thisreason, it is taken into account for the admissible tensilestrengths of the inset parts.

Acceleration zone

Delay zoneProfile joint resistance

Two ways are available to calculate the profile joint resistance. One one hand, the admissible height of the centre ofgravity of the flight can be roughly determined depending on the profile mass and other parameters (page 39). Then,this value serves as a guide value for the profile design. On the other hand, the „ATN-CONNECT“ PC calculationprogram can be used to recalculate the strength and thus optimise the joint based on several geometrical, kinematicand material parameters. Please ask your responsible Mulco partner.

In addition to the belt type and/or width selection according to the circumferential force load, as describedon page 10, the selection can also be based on the profile joint load.

• Pushing force FTG of theproduct to be transported

• Inertial forces FTP

How to determine the admissible height of the centre of gravity of the profile

Starting point for the determination are the preselected values for belt pitch and width, pulley and/or rollerdiameter, transport speed and profile geometry as well as its mass. The diagrams contain the admissibleheights for the profile centre of gravitydepending on the determined pulley diameter, transport speed and profile masses. The conversion to otherparameters is made based on the interrelation stated on page 41. For pulley diameters not contained in thediagrams, a respective approximation or interpolation is required.

Calculation example

Metal brackets are to be fastened on a 50 ATN 10 timing belt to push the products to be transported (seesketch).

Given: Belt type: 50 ATN 10Pulley diameter: d0 = 133.69 mmSpeed: v = 2 m/sProfile mass (angle mass): mP = 325 gProfile support width: lZP = 15 mmBrass inset part with metal profile

Required: admissible centre of gravity height for the metal bracket

Solution: 1. The admissible centre of gravity height is determined using the diagram on page 40. Refer topage 39 for the procedure. For the pulley diameter d0 = 133.69 (z=42) mm select the diagramwith the closest diameter (d0 = 127.32 mm). For v = 2 m/s and mP = 325 g this results in: hSP = 10mm.

2. Adapting the parameters of page 40 to the example calculation(calculation equation, see above).• Profile support width from 10 mm to 15 mm:

• from plastic inset part with polyamide or metal profile to brass inset part withmetal profile:

Attention: The current value in the calculation order is always valid as curve valueto be used. Here, 12.2 mm from the calculation of the profile support width.

Result: The admissible centre of gravity height for the parameters stated in the example is:h

SPadm = 22 mm. With this the profile joint resistance is guaranteed.

Information on profile installation

To prevent the inset parts from being twisted duringprofile installation, the belt should be inserted into atoothed plate with the respective pitch. The offeredmounting plate made of plastic (see left picture) canbe fastened to a worktop to permit reliableinstallation of the profiles. For this purpose, themounting plate is equipped with a threaded insert,size M 5.

Take the respectively recommended screw-in torqueinto consideration when tightening the screwconnection for profile fastening (see table on pages18 and 19).

If the threads of the plastic inset parts areovertightened when tighten the screws, replace theaffected inset parts.

Information on the ATN timing belt systemapplication

Ensure that the centre of gravity of the profiles andpossible attachment parts and the products to betransported are as close as possible to the back of thebelt. When using pulleys with flanges take intoaccount that the flange heigth could protrude fromthe back of the belt. Consider the position of theproduct to be transported and the profile widthaccordingly.

If possible, avoid large profile masses with highcentres of gravity when operating at higher runningspeeds. However, at least, a calculation of the load tobe expected should be made.

Select a profile foot as wide as possible for heavyprofiles.

To avoid strong variations of large and heavyprofiles, ensure that they are not located on theangle of wrap during a start-stop process.

Piercing tool

The shapes for the inset parts are factory sealed withan approx. 0.2 mm thick PU skin to avoid small dirtparticles from falling through. Open these shapes toinset the profile fastenings. For this purpose, we offera simple piercing tool. If you want the timing beltdelivered pierced, please inform your responsibleMulco partner when ordering.
