| | | |
| | | 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. | | |
