Zusammenfassung:	Invention refers to woodworking equipment and can be used in sawing- woodworking industry. The purpose of the invention is simplification of installation of saws on the shaft. The device includes saw shaft 1 with basic 2 and demountable 3 tightening washers. In cavities of washers 2 and 3 on the shaft 1 by means of a threaded connection the cone spigot 4 is installed. In a basic washer 2 movably in the radial direction three spring-loaded cams 6 are installed supplied by a fillet contacting with a cone surface of the spigot 4. Rotating the cone spigot 4 on the thread of the saw shaft 1 moves it in an axial direction. The conical surface of the spigot 4 telescopes cams 6 in the radial direction and their fillets form a mounting surface for the slitting saw. Application of the offered device allows to simplify installation drank on the shaft due to selection of diameter of a mounting surface for a concrete saw. 2 figs.
