Asymmetric Variable Speed Belt Drives - 0.25 to 30 KW (With Automatic Torque Sensing Device) (Interchange to BECKER / BERGES)

Assymetric Drive is suitable for 0.25 to 30 Kw motor ratings. The stepless output Speed Range in case of 1440 RPM Motor is from 425 to 4500 RPM. This drive is consisting of driveR Pulley (Mounted on Motor Shaft), driveN Pulley (Mounted on Gear Box/ Machine Shaft) and a Belt. DriveR Pulley is mechanically adjusted by means of screw spindle to achieve speed Variation and driveN Pulley gets automatically adjusted.

The drive has unique features of "Automatic Torque Sensing Device", which ensures optimum automatic axial contact pressure on the Belt, depending on rating of power to be transferred. Greater the torque, greater the Contact Pressure. This ensures that the belt does not slip during the intermittent operation, under excessive load or when the machine starts with flywheel effect. These features of the system guarantees very high efficiency, even under partial load and longer belt life.

Special Features

• Disc mounted on Hub without key or splines thus minimises the wear
• Speed Variation Ratio 11: 1
• Life time Lubricated
• Speed adjustment while the machine is in operation
• Dynamically balanced
• Finish bore with Keyway

When Selecting, the following are essential to start the process

How to Select Assymetric Variable Speed Drive & Belt

• Motor Power & speed range - refer TABLE 1 for drive selection.
• Check whether driveN pulley can accamodate the bore size of gear box / machine shaft - refer TABLE 1 or else, select one size above.
• Center to center distance between motor & gear box / machine shafts - refer TABLE II nd for' belt selection.
