· Variable speed drives demand a unique combination of belt features. Because these belts are wide in proportion to their thickness, they must have extreme crosswise rigidity · Without it, the belt will dish in, throw the tensile cords out of alignment, and affect speed control. · Variable speed belts also require lengthwise flexibility to bend around small sheaves without excess strain that will shorten belt life. · Bando’s cog design solves these potential problems by providing excellent flexibility, without sacrificing the crosswise rigidity required to properly position the tensile cords. · The result is precise speed control, a wide range of speed ratios, and long, dependable service |
