Pivot with pivotable connecting flap and one-sided open bolt accommodation - is for tensioning machine saw for cutting granite and has saw blades connected to it by bolts

摘要

The pivot (1) on its side facing the saw blade end has at least one connecting flap (5), which by means of a shaft (6) is rotatably connected to the shaft of the pivot. The flap width is smaller than the frame traverse distance (4) and the horizontal length of the bolt accommodation (5.3) at least on it opening side is 2 mm larger than the dia. of the bolt (7). The centre point of the radius for accommodation of the bolt (7) is located near the width centre of the flap (5). The flap (5) on its rear side has a recess (5.1) and/or at its front end insertion inclined surfaces (5.2). The pivot shaft has a stop so formed that the bolt is located somewhat below the longitudinal centre of the bolt accommodation (5.3), when the saw blade end is in contact with the stop. USE/ADVANTAGE - The pivot in its vertical position can be pushed through the opening of the frame traverse, and is for tensioning machine saw blades for cutting granite.
