Toothed belt coating for high temperatures

14.06.2022/XNUMX/XNUMX | For transport drives with a Breco timing belt Mulco has a new coating material that can withstand very high contact temperatures. In some applications, such as glass or aluminum processing, very hot products have to be transported on the back of the belt for a short time. Toothed belts coated with 4 mm aramid felt easily endure products with temperatures of up to 250 °C, which come from a heating oven, for example. 

During tests by Breco Antriebstechnik, contact was made in a moderate ambient temperature of max. 80 °C Temperatures of up to 250°C confirmed as safe. The toothed belt coating can even be exposed to temperatures of up to 500 °C for a short time. However, this only applies to exceptional cases, because the fibers suffer external damage relatively quickly.

The aramid felt forms a very good connection with the TPU of the toothed belt and can also be attached to it without adhesive. The joint of the toothed belt must remain open on the back. In this way you get a blunt joint without glue in the blunt area.

A toothed belt with an aramid felt coating has a minimum pulley diameter of 120 mm. Mechanical post-processing to possibly reduce the thickness is not possible. the width tolerance is -0,5mm / +1,0mm.

Rollers in conveyor belts significantly increase performance


25.03.2021 | Mulco presents Brecoroll, a new polyurethane Conveyor belts, when rolling into the teeth of the drive belts are integrated. In material transport systems, they reduce the sliding friction between the support rail and Timing belts. Efficiency and service life are increased significantly.

Toothed belts, which are used to transport materials, are usually very long and run in a guide rail. The rail supports the transport belt and absorbs the weight of the transported goods and the belt. This creates a Sliding friction between belt and support rail. Additional drive power is necessary to overcome the sliding friction. Self-heating occurs, which reduces the strength of the timing belt and thus also reduces its service life.

The rollers in the teeth of the Brecoroll toothed belt, on the other hand, mean that the sliding friction with µ> 0,5 is much smaller Rolling friction is replaced with µ <0,2. This reduces the drive power required. Thanks to the lower heat generation, the service life of the toothed belt is increased.

Brecoroll is designed for speeds of 1 m / s and surface loads of 3 kg per roller. With these properties, this new, patented conveyor belt is suitable for most material handling applications in manufacturing automation.

The drive element is available in T20 pitch, 100 mm wide, by the meter and as a welded V belt. Special materials and colors as well as back coatings are available on request.

Connect the timing belt mechanically and quickly using a heating press

07.02.2020 | Habasit offers high-quality toothed belts from the Habasync series with practical mechanical end connections for quick changes. This allows the operating costs of conveyor lines to be reduced through short assembly and maintenance processes, such as when changing the toothed belt. 

endless belt can also alternatively be connected to mobile heating presses directly on site. This also significantly reduces downtimes when changing a toothed belt.

Disruptions in the flow of materials lead to high costs, because machines and systems must run as uninterrupted as possible. Maintenance work on conveyor systems should therefore be minimized as far as possible. One of the most time-consuming jobs is timing belt replacement. The often difficult access makes changing the timing belt in the event of wear or damage a cumbersome procedure. Habasit therefore relies on high quality and simple, reliable end connections for its timing belts. Timing belts are available in a wide range of lengths, shapes, structures and surfaces. The materials used have a long service life.

The belt widths of the toothed belts range from 10 to 600 mm. The timing belts are made of thermoplastic polyurethane and some have a FDA / EU compliant fabric coating. The thermoplastic polyurethane with a hardness of 85 to 92 Shore A is also a material with very good properties. So it is resistant to oil, grease or chemical agents and hydrolysis. The endlessly manufactured Habasync toothed belts are particularly suitable for heavy loads. Spirally wound tension members ensure increased tensile strength compared to toothed belts with one end connection.

Through the use of mechanical Terminations Habasit hinge joints, pin joints and PA hinges make changing a timing belt much easier and takes less time. Even toothed belts with coatings can be easily joined using the variants mentioned, with all the teeth of the belt remaining complete and without gaps.

Are suitable for higher transport loads end-connected toothed belts. For their on-site assembly, Habasit offers the PML-100 portable joining press. It enables the hot joining of fabric tapes and toothed belts. Tapes and belts can be connected directly in the system for a new installation or repair.

Timing belts in the highest bandwidth for drive and conveyor technology

22.01.2019/XNUMX/XNUMX | the HabaSYNC High-performance timing belt from Habasit offer a wide variety of shapes, lengths, structures and finishes and low running costs thanks to durable materials and easy maintenance processes. The belt widths range from 10 to 600 mm and are therefore the widest timing belts currently available on the market with pitches T10 or H.

With other divisions there is also the possibility of a longitudinal seam connection with which widths up to and over 600 mm can be realized. The toothed belts are made of thermoplastic polyurethane with an aramid tension body.

The thermoplastic polyurethane with a hardness of 88 to 92 Shore A (depending on the type of base material) is also a material that has outstanding properties in a wide range of areas: on the one hand, it is resistant to oil, grease or chemical agents, and on the other hand it is resistant to hydrolysis. In order to minimize abrasion during work and thus significantly increase durability and service life in extreme applications, the high-performance toothed belts are also equipped with a polyamidecoating available.


Chuck innovations for efficient metal processing


The endlessly manufactured Habasync are suitable for particularly heavy loads Flex timing belt. Spirally wound tension members ensure increased tensile strength compared to timing belts with an end connection. They can also be used for high power transmissions where chemical resistance and wear resistance are beneficial.

Through the use of mechanical Terminations Hinge joint, pin joint and PA hinge make such timing belt changes extremely easy and they can be carried out within a very short time. Even toothed belts with coatings can be easily joined with the variants mentioned, with all teeth remaining complete and without gaps.

PU high-performance timing belts now also in 15 mm pitch

15.05.2018 | Mulco expands its high-performance timing belt family Move a new division of 15 mm. As with the versions with a 10 mm pitch, a significantly increased belt rigidity was the most important development goal for the 15 mm pitch. This is of particular importance because the load capacity of a toothed belt drive is usually not limited by the tear strength of the toothed belt, but by its rigidity. The performance limit is reached when the belt pitch becomes so large due to elongation under load that meshing on the sprocket no longer runs smoothly.

Despite the stronger tension member in the AT15Move Standard toothed pulleys can still be used with toothed belts. In order to be able to transmit the larger torques cleanly and without wear, the tooth flank was also FEM-optimized. A laminate on the tooth side reduces friction and leads to smoother running of the toothed belt. A smaller minimum diameter with and without counterbending accommodates customer requests for more compact drives.

The Brecoflex Move are available in widths of 25, 32, 50, 75 and 100 mm. Apart from the larger torques that can be transmitted, users benefit from higher positioning accuracy and shorter settling times with dynamic drives. Alternatively, steeper start and stop ramps can also be used. The endless variant Brecoflex move AT15 is now available. It will be available by the meter from the third quarter of 2018.

Calculate, design and order toothed belt length online

11.04.2018 | Madler offers an online tool for the design and ordering of toothed belt drives. This allows, for example, the Calculate timing belt length. This free timing belt calculation program for all top brands can be started without login and calculates the common types and sizes.
