VECOBLOC® STATIONARY VARIABLE PITCH PULLEYS
FICHE TECHNIQUE
61001 - 1 - 08/97
TECHNICAL DATA SHEET
Stationary variable pitch pulleys for V-belts are mainly used in the fan industry. These pulleys allow adjustment to optimum working speed of fans by a simple operation on one pulley only.
Adjustment
Modifications of the pulley diameter must be done when stationery by moving the adjustable flange using a jacking screw.
Adjust the pulley to the required diameter by moving the screw 1. Moving the flange by 1,25 mm results in a variation of the diameter by approximately 4 mm. When you get the required diameter, lock the mobile flange with the screw 2 to avoid any untightening.
