In case of main spring failure, it is recommended that the entire spring barrel and gear be replaced. since the procedure of spring installation requires a good deal of care and involves slight danger. The additional cost of the spring barrel is offset by the saving in labor. GOVERNOR WORM MAIN

14、 SPRING BARREL WINDING SHAFT SPRING GOVERNOR ADJUSTMENT The mesh of the worm and fibre gears is adjustable by rotation of the two governor spindle bearings. This operation shifts the spindle bearing boles, due to their eccentric loca- tions in the bearing parts as shown in the illustration. To obtai

15、n the proper mesh between the gears, turn the bearings so that the worm moves in toward the fibre gear and binding occurs.Then gradually back off on the bearings until smooth operation is obtained. The action of the mechanism can be tested by spinning the governor during the adjustment and noting ho
