Falcon PD 3. Generation

Extreme Power

Falcon PD is setting the new standard in synchronous drive system belting. When compared to conventional polyurethane synchronous belts, the benefits of Falcon PD become evident.

Tooth composition

  1. patented reinforced rubber
  2. temperatures up to 95°C
  3. static conductivity

Falcon PD synchronous belts do not require lubrication often found in chain drive applications. High-modulus cord members minimize the need for retensioning normally required in standard v-belts, reducing your overall maintenance cost.

The revolutionary drive system

The Falcon PD can easily and seamlessly replace old-fashioned chain drives with a clean and quiet rubber compound belt that delivers exceptional performance under higher torque and lower speed applications.

Our advanced rubber compounding research has resulted in a synchronous belt that has exceptional tensile strength, superior resistance to flex fatigue, less noise and resistance to chemical and oil breakdown. Plus, the system is specially designed to accommodate today’s high-efficiency motors, with a power transfer rate of up to 98%.

And with one of the best backside idler capabilities in the industry, changing from chain to Falcon PD can be as easy as switching out sprockets; meaning less re-engineering and downtime.

Advantages of the Falcon PD:

  • Power capacity increased by 30%
  • Quieter operations
  • Static conductivity
  • Superior flex fatigue resistance
  • Higher temperature capability
  • Backside idler capability
  • Suitable for higher torque, lower speed applications
  • up to 98% energy transfer

Special construction

This belt is also available with Carbon Cord that is suitable for even higher torque and flex fatique.

Only available via request.

In order to achieve optimal performance and as long a service life as possible, timing belts have to be correctly installed, correctly tightened and correctly aligned. Prior to installation, it is always recommendable to inspect the belts for any possible damage resulting from transport or storage.

 

The Correct Mounting

Pulleys and, of course, belts themselves always have to be mounted with the correct alignment. This means that belts cannot be bent or buckled in any way, which could lead to a drop below the minimum permissible pulley diameter. That corresponds to approximately 50 mm for belts with a pitch of 8 mm and about 125 mm for those belts with a 14 mm pitch. Imbalanced drives cause a variety of belt tension problems and edge stresses and are also responsible for extreme lateral movement, the undesired wobble. All this leads to increased operating noise and more wear and tear on the belt. Therefore the parallelism error of the pulleys should only amount to a maximum of 0.5% of the centre distance. Angle accuracy is to be maintained by keeping misalignment down to 0.25° at the very most.

Pre-Tensioning The Belt Correctly

Firstly the belt always has to be tightened in line with the calculated pre-tensioning force and checked after a running-in period of about 5 minutes. The belt is then to be retightened according to the relevant value, should it have shifted or altered its position in any way. Finally after a further 8 hours of operating, the belt is to be once again inspected and, if necessary, tightened to comply with the required value that has already been calculated.

Causes of failure and corrective measures can be found in the following document:

The shaded figures assume a speed of more than 50 m/s. Special high-speed gears are required.
Total operating factor c0 = c2 + c3
Load factor c2 Examples of drive units
Electric motors with low starting torque (up to 1.5 x nominal torque)
e.g. DC shunt motors,
combustion-
engines with 8 or more cylinders, water and steam turbines
Three-phase and AC
motors with normal starting torque (1.5-2.5 x nominal torque) e.g. DC shunt motors with compound winding, squirrel cage motors, combustion engines with 4-6 cylinders
Three-phase and AC motors with high starting and brake torque (exceeding 2.5 x nominal torque) e.g. single phase and synchronous motors with high torque, combustion
engines up to 4 cylinders
