Berges BECKER Asymmetrical Pulleys with Variable Speed Adjustment
Berges asymmetrical variable speed pulleys with continuous speed change – BECKER system – are used to continuously change the speed using a V-belt or variator – wide V-belt. It is made of aluminum alloy.
These are special pulleys that allow you to change the width setting and thus the position of the belt. The result is a transmission with a smooth change of speed and gear ratio without the need to stop the transmission. Controlling the width of the drive pulley, or speed changes, can be mechanical, hydraulic or electronic.
The BECKER system is a special asymmetrical version of the variable speed pulley, where each side of the belt has a different pitch angle. One side of the variator has an angle of inclination of 3 degrees and the other side of 17 degrees. This asymmetrical design enables better distribution of forces, less stress on the shaft and bearings, greater rigidity and longer service life.
Pulleys Construction
- Drive pulley
- Spring pulley
- Belt
- Speed adjustment device
Pulleys Fields of Use
Berges BECKER asymmetric variable speed pulleys are intended for applications, where the transmission is realized by a special asymmetric variator belt. Power from up to 150 kW can be transmitted using variator transmissions.
They are typically used in machines where the change of speed is provided mechanically, especially in presses, single-purpose machines, agricultural machines and other applications.
Pulleys Characteristics
- Higher lateral stiffness
- Reduction of centrifugal forces
- Lower operating temperature of the belt
- Higher load capacity and longer V-belt life
- Easier pulley installation and alignment
Pulleys Material
