Annular circular saw, in particular for wood and stone

摘要

Annular circular saw, in particular for wood and stone, wherein the annular saw blades are guided and driven by machine elements arranged concentrically thereto, wherein a rim (2) is welded on the saw blades (1) at the inner circumference, in which rim run the friction wheels (5) which guide and drive the saw blade (1) via the rim (2), the rim (2) consists of two spring-steel bands (2') which are pressed together by their own spring force in the region of the kerf but which are spread apart by the friction wheels (5) outside the kerf, the spring forces thus produced in the rim (2) generate a friction moment and push the saw blade (1) radially outwards, and the rim (2) rests like a saddle on the elastomeric friction lining (15) of the friction wheels (5). <IMAGE>
