In the industry, the drive belt is crucial for the synchronisation of mechanical parts in machines. With its teeth, it transmits motion and power between two pulleys for increased system efficiency.

The numerous references in the Rubix catalogue support you in your projects with slip-free transmission chains. Even in demanding environments, your machines gain reliability whether for maintenance or operation.

The choice of a type of timing belt directly depends on the targeted industrial application. Each configuration meets specific requirements.

• HTD profiles (3M, 5M, 8M, 14M, 20M) offer a rounded tooth design. This is specifically designed to transmit high torques while avoiding slippage.
• Metric drive belts have their pitch expressed in millimetres (T5, T10, AT5, AT10, etc.). Made from polyurethane and reinforced with cables, they are used for conveying applications and synchronous linear movements.
• Imperial profiles (XL, L, H) made of rubber are generally used in traditional transmissions. These belts, with a pitch expressed in inches, are reinforced with fibreglass cables. They ensure good mechanical resistance.
• Endless extruded ranges are perfectly suited for conveyors and any system requiring continuous movement.

Equipped with rounded teeth, HTD drive belts extend the lifespan of components. They are widely used in machine tools, production installations, and industrial drives requiring consistent motor torque.

From 3M to 20M, the pitch of the profiles ensures precise sizing. Its choice depends on the transmitted power, the height of the belt, and the available space. When paired with suitable pulleys, these belts will provide optimal efficiency and a high level of reliability. This is a significant advantage for applications requiring excellent transmission consistency and high performance.

Rubix distributes the best references on the market to provide a wide choice for professionals:

• Like the ALPHA LINEAR models, the Optibelt brand offers polyurethane belts valued for conveying applications.
• The PowerGrip HTD range from Gates covers all pitches from 3M to 20M. The various models are perfectly suited for robust industrial gears and drives.
• Exclusive to Rubix, Mecaline provides models made from CR rubber. They are reinforced with fibreglass cables and standardised according to the XL/L/H code.

With a complete stock and fast shipping, purchasing your belts from Rubix guarantees reliability.

Timing belts offer a real advantage over chains. They promote quiet operation and high efficiency. They also provide increased precision in synchronous movements.

Choosing wisely involves precisely defining several parameters:

• The pitch and number of teeth, as well as the width and height, impact the system's performance.
• The power and torque transmitted must align with the diameter of the chosen pulleys.
• In terms of working environment, heat, dust, or contact with oils will influence your choice. It is recommended to opt for CR rubber or polyurethane, depending on the expected resistance.
• The selected profile (HTD, T/AT) must correspond to the intended application. This could involve production synchronisation, conveying, or linear use.

The lifespan of a timing belt varies depending on the applied tension and the alignment of the pulleys. The chosen diameter and working environment also affect its durability. Wear will depend on the loads supported, the rotational speed, and the quality of maintenance. CR models reinforced with fibreglass cables withstand standard demands. For more intensive cycles, steel or aramid-cabled polyurethane is ideal.

Regular maintenance is essential. This involves checking for tooth wear, signs of fraying, and contamination from oils and dust. Cleaning must be done dry to preserve the belt material. For continuous productivity, it is recommended to schedule a replacement after a predetermined number of hours or cycles.

An optimal installation must follow certain steps:

• Check the condition of surrounding parts;
• Verify the alignment of gears or pulleys;
• Ensure compatibility between your installation and the chosen reference;
• The belt must be installed without excessive strain and according to the tension recommended by the manufacturer;
• Conduct a start-up test followed by a check.
