power transmission and drive belts

Power Transmission & Drive Belts

Past the initial machinations of belts that convey and manipulate products, power transmission and drive belts do the essential work of propelling application lines forward and continually running efficiently. Working under great duress, these belts transmit power from a source to a driven pulley using expertly calibrated arc of contact, tension, coefficient of friction and strength — and MIR engineers products to meet these high-caliber characteristics.

What power transmission belts does MIR provide?

MIR provides power transmission and drive belts in a broad range of power options, from low-speed high-torque applications to the fastest tangential drive. We engineer both flat power transmission belting and synchronous power transmission belting to meet the pulley diameter and horsepower requirements of your facility.

Flat belting is a highly efficient solution for power transmission belting, boasting energy efficiencies as high as 99%. We engineer flat belting solutions to suit the inertial force and shock loading of the drive, the abruptness of the drive start and the presence of contaminants such as oil, water and grease. Flat high efficiency belts are fabricated out of highly oriented nylon, aramid fiber or polyester fiber, depending on the application. These belts are almost always spliced truly endless to endure the duress of power transmission applications, convey greater horsepower and negotiate small pulley diameters.

Our synchronous belts (different from the conveyance timing belts we provide) also function in power transmission applications. MIR fabricates truly endless synchronous belts from traditional polyurethane for high speed and high horsepower applications, while high-performance rubber synchronous belts provide high resistance to oils, coolants, ozone and heat. Traditional neoprene belts are also available with precision slitting to the exact width for your application.

MIR’s power transmission and drive belting is used in applications such as, but not limited to:

  • High-speed balancing
  • High-speed grinding
  • Woodworking
  • Tape drives
  • Serpentine drives
  • Centrifuges and liquid agitators
  • Slotting, planing, milling and drilling
  • Light tube-winding
  • Centrifugal pumps and compressors
  • Small, medium and large fans
  • Low output generators
  • Automatic lathes
  • Live roller drives

Advantages of flat power transmission belts

Unmatched efficiency

The thin-cross section and flexibility reduce centrifugal force and energy consumption while allowing an increase in speed and horsepower capacity — this means efficiencies as high as 98% to 99%.

High speed, low vibration

Even while reaching high speeds up to 75 meters per second, flat belts will still run vibration free. This prevents any unforeseen product damage or equipment malfunction.

Application flexibility

Flat belts can handle reverse bends, run a serpentine path and negotiate pulley diameters as small as 1/4”, making them a viable option for a variety of power transmission applications.

Quiet and clean

The low vibration quality of these belts means limited noise and facility cleanliness: These belts can run directly in the air stream without shedding rubber particles like multi-v belts are prone to do.

Engineered slippage

If your power transmission application requires a degree of slippage during start up, we can engineer your belt with the appropriate coefficient of friction to generate that slippage.

Advantages of synchronous power transmission belts

Efficiency through positive drive

Sprocket-driven synchronous belts see minimal tracking issues, leading to less overall downtime for maintenance and overall increased efficiency.

Material durability

Synchronous belts fabrications are built to withstand demanding operating conditions, with specific fabrication options offering high resistance to environmental contaminants. This facilitates greater belt lifespan.

Shock-load start capability

When a power transmission application requires a belt to go from stationary to 60 feet per minute, synchronous belts can withstand the shock-load start because of their high torque.
