Adjusting Cone: Description and Applications.

This kind of pulley is suitable for industrial equipment thanks to the reliability of the adjusting system that makes use of bolts and cones.
Pulleys that come with adjusting cones reduce the possibility for axial movement, all of which allows the belts to be accurately aligned.
These pulleys are mostly used by oil, food processing, agriculture-based and mining industries, as well as in those pieces of equipment requiring high quality components.
Adjusting cones make it easier for pulleys and other components to be assembled and disassembled since pull-up bolts can also be used as back-off bolts for easiness of use and time-saving purposes.

   

 
       

   
       

INSTALLATION

  1. Make sure that conical surfaces of the cones and the pulley hub inside are clean.
  2. Place the cone on the pulley.
  3. Lay the screws and washers without tightening them. The cone should remain loose so that it can move freely along the shaft.
  4. Once the key is on the shaft, slide the pulley on said shaft until the desired position is reached Make sure that screw caps are located outside.
  5. Align the pulley. Tighten the screws alternatingly and progressively, until they remain fixed. Employ a wrench or a tube in order to increase leverage.
      Do not allow the pulley to come into contact with the cone flange; the distance between them should be from 3.3 to 6.4 mm.

 

PRECAUTION:

                        Apply only manual pressure when laying the screws. If too much strength is applied when tightening them, a dangerous pressure will
                  be generated on the pulley hub. There should be a gap of 3.2 to 6.4 mm between the pulley hub face and the cone flange, which must
                  not be shut.
                        Should the gap be shut by action of a standard tightening force, it means that the shaft is under-sized.
