Abstract
A ring saw includes a ring saw blade, a tool holder that guides the ring saw blade in a cutting plane, a motor, and a driving wheel where the ring saw blade is drivable in the cutting plane by the driving wheel and the driving wheel is coupled to the motor. A guide roller is disposed on a first side of the cutting plane where the ring saw blade is guidable by the guide roller from the first side. A guide roll is disposed on a second side of the cutting plane where the ring saw blade is guidable by the guide roll from the second side. The guide roll is disposed in a hood that is pivotable relative to the cutting plane.
Claims8
A ring saw (2), comprising:
- a ring saw blade (1);
- a tool holder (5), wherein the tool holder (5) guides the ring saw blade (1) in a cutting plane (E);
- a motor (30);
- a driving wheel (6), wherein the ring saw blade (1) is drivable in the cutting plane (E) by the driving wheel (6) and wherein the driving wheel (6) is coupled to the motor (30);
- a guide roller (41) which is disposed on a first side of the cutting plane (E), wherein the ring saw blade (1) is guidable by the guide roller (41) from the first side;
- and
- a guide roll (43) which is disposed on a second side of the cutting plane (E), wherein the ring saw blade (1) is guidable by the guide roll (43) from the second side;
- wherein the guide roll (43) is disposed in a hood (34) that is pivotable relative to the cutting plane (E);
- wherein the driving wheel (6) is movable in the cutting plane (E) and wherein a movement of the hood (34) and of the driving wheel (6) is synchronized by a linkage mechanism (71).
A ring saw (2), comprising:
- a ring saw blade (1);
- a tool holder (5), wherein the tool holder (5) guides the ring saw blade (1) in a cutting plane (E);
- a motor (30);
- a driving wheel (6), wherein the ring saw blade (1) is drivable in the cutting plane (E) by the driving wheel (6) and wherein the driving wheel (6) is coupled to the motor (30);
- a guide roller (41) which is disposed on a first side of the cutting plane (E), wherein the ring saw blade (1) is guidable by the guide roller (41) from the first side;
- and
- a guide roll (43) which is disposed on a second side of the cutting plane (E), wherein the ring saw blade (1) is guidable by the guide roll (43) from the second side;
- wherein the guide roll (43) is disposed in a hood (34) that is pivotable relative to the cutting plane (E);
- wherein an actuating lever (35) has an opening position and a closing position, wherein the hood (34) and the driving wheel (6) are coupled to the actuating lever (35) such that, in the closing position, the hood (34) is closed and the driving wheel (6) is pressed against the ring saw blade (1) and, in the opening position, the hood (34) is open and the driving wheel (6) is at a distance from the ring saw blade (1).
