FAQ

The easy drive® system has many real advantages and is clearly superior to other existing  guide systems. easy drive® with its important advantages in details:

Previously (without easy drive®), there were three solution variants for guiding timing belts:

• Timing belts run on pulleys with flanges designed to prevent the timing belt from running off the pulley.
• Timing belts are guided by an integrated V-guide in the timing belt on the pulley.
• Timing belts are designed with special tooth shapes, such as BAT (curved-tooth) belts or EAGLE, to reliably stay on track.

The most important disadvantages of the previous guide systems (without easy drive®)

• Large side play on the pulley when using flanges.
• The use of flanges and special tooth forms is significantly more complex in terms of design and therefore more cost-intensive.
• Nevertheless, the guidance requires a tolerance play in the running behavior.
• The installation space in the systems is severely restricted due to the need for larger pulley diameters.
• Special tooth forms can usually only be used in one running direction.
• When using flanged pulleys, timing belts can run onto the flanged pulley and cause the timing belt to crack or break.
• There is a risk that the timing belt may push the flanged pulleys off the pulley or that the tension cord may get pulled out of the timing belt sideways by contact with the flanged pulley.

easy drive® solves all these disadvantages:

• There is no side play in the timing belt run, the timing belt runs completely backlash-free and securely on the pulley.
• The design is simple: can be implemented with the smallest possible pulley diameter, without special machining of the pulleys for the tooth forms and without a division of the running table (as otherwise/previously necessary for flanges).
• Can be used and retrofitted for all pulleys and timing belt pitches.
• easy drive® is the only reversing system suitable for timing belts.
• easy drive® ensures high operational reliability and individual application options.

Yes, of course, for this purpose the existing pulley only has to be provided with a groove and an easy drive® ring, (by reworking or replacement), and the timing belt has to be provided with a corresponding groove.

In principle, yes, but in terms of function and the resulting effects, easy drive® has many advantages over all other implementations.

For a guide with integrated v-guide, larger pulley diameters are required.

The V-guide requires a guide clearance and thus a higher tolerance for the groove in the pulley of approx. 1 mm in order not to rise up and run out of the guide.

The V-guide in the timing belt also requires a groove in the transport table.

This results the V-guide constantly running along a standing edge over the entire length of the load run, which inevitably leads to increased abrasion and wear.

In addition, timing belts with extruded V-guide are only available for a few belt types and only for narrow belts.

And with easy drive® ?

In contrast, the easy drive® system guides without backlash, requires no groove on the running surface between the deflections and no larger pulleys (minimum installation space). And, very important advantages: Therefore, no increased abrasion and easy drive® can guide all tooth forms.

Yes at first glance, but there are major disadvantages with the standard designs and a certain degree of operational uncertainty.

In some applications this can be unproblematic, but if a longer service life due to less wear, smoother running, improved guidance and the operational reliability of the system are important, then the use of easy drive® always has a clear advantage.

In the standard versions, the timing belt runs between the flanged pulleys and can run heavily against them. If a flanged pulley is pushed away by the lateral forces, the timing belt runs off the pulley easily and the entire system comes to an undesired standstill.

The constant striping/running of the timing belt on the flanged pulley leads to wear and the timing belt is rubbed off laterally. This leads to the tension cord in the timing belt escaping and can lead to increased wear with damage, up to and including failure of the complete system.

The timing belt cannot be positively guided between the flanged pulleys and requires a lateral play of 2-3 mm in the run. The timing belt can therefore oscillate strongly between the flanged pulleys on the toothed pulley, especially in the case of revers running, i.e. it cannot run precisely.

This leads to positioning errors in the case of conveyor timing belts, to uneven running in the case of drive belts, and to higher axial forces on the bearings in all applications.

The easy drive® system eliminates all these disadvantages:

The belt therefore runs backlash-free and precisely, cannot be rubbed off sideways, positions precisely and is therefore more accurate for the entire system and the entire plant, almost wear-free and thus significantly more durable.

Higher costs for the initial use respectively the conversion to easy drive® are almost completely compensated or even more profitable, and lead to high customer satisfaction and safety in use in addition to the precise, long service life.

The timing belt guide with 'eagle' is a good solution, but there are certain limitations in the possible designs.

eagle timing belts are only available in the limited designs

5M to width 25 mm, 8M to width 50 mm, 10M to width 100 mm, 14 M to width 105 mm.

The easy drive® system, on the other hand, can be used for all timing belt types, from T2.5 to AT20 and from HTD, STD or RPP5M to 14M, and for the smaller pitches in widths of up to 100 mm and for the larger pitches even up to a width of 150 mm. For the pitches H, T5 and T10 even up to a width of 500mm. In other words, universal for all tooth forms. This is unique.

Experience has also shown that “eagle” timing belts wear much faster than timing belts guided by easy drive® if the pulleys have angular errors or if there are small deviations between the pulleys.

This special tooth form is also only available to an extremely limited extent in pitches of 10 and 15 mm up to a width of 100mm.

For reversed operation, these timing belts require a V-guide with the disadvantages already described above.

The easy drive® system can be used for all timing belt types, from T2.5 to AT20 and from HTD or RPP5M to 14M, in widths of up to 100 mm for the smaller pitches and up to a width of 150 mm for the larger pitches. For H, T5 and T10 even up to a width of 500 mm. This means that they can be used universally for all tooth forms.

Timing belt sleeves are endless molded timing belts made of polyurethane or neoprene, which find their use in drive or transport applications (also with appropriate coatings).

In principle, all timing belts sleeves can be guided with easy drive .®

However, in order to insert the groove for the guide into the timing belt, it is necessary that the length to width ratio exceeds a factor of 3.8 so that these can be turned for production. This is necessary to mill the easy drive® groove in the timing belt.

Once again, a great advantage of easy drive® : Yes, all neoprene timing belts, for which there is no possibility of guidance so far, can be applied with easy drive® according to the questions, conditions and advantages already described above.

Yes all timing belt types can be guided with easy drive®.

For inch timing belts, there have been no other options for guiding, except with flanged pulleys on the timing belt pulleys, neither for PU nor for neoprene timing belts.

Here again the great advantage of easy drive®: Suitable for all timing belts and universally applicable with easy drive® according to the already described questions, conditions and advantages.

Our easy drive® slogan "innovative, efficient and universal" says it all.

The easy drive® system is the best solution in both transport and drive for timing belts because it can be used universally and is full of advantages for drive belts (see above).

With drive belts, smooth and accurate running is of course extremely important, and easy drive® offers the best possible guidance, reducing vibrations in the timing belt and thus ensuring much lower stress on the running bearings.

In most drive applications, pulleys with flanges are used, which leads to the disadvantages described above. When using easy drive®, on the other hand, the timing belt cannot run sideways and therefore has less wear. This significantly increases the running time and operational reliability, which always pays off.

easy drive® offers immense advantages in all transport and drive applications in terms of durability, precision and diversity in universal use. Coated belts and profiled belts are also much easier to guide with easy drive®

easy drive® is used for example, in the packaging industry, where the systems have now been used successfully for many years in a wide range of applications, for transport applications and also drive solutions.

The successful application of easy drive® systems can now be found in a wide range of industries and applications, such as logistics, stacker cranes, textile machines, folding carton machines, labeling machines, linear units, transport of products in manufacturing such as wafers and solar cells, feeding units and many other versatile transport applications.

In the drive, the easy drive® system is always used when smooth running and constant bearing forces are required.

In principle, the easy drive® system can be used for all toothed pulley sizes.
