Abstract
A dog clutch for a power tool such as a chain saw for engagement and disengagement of the motor from the cutting tool comprising a first gear (32) mounted on and attached to a rotatable spindle (34), a second gear (36) rotatably mounted adjacent the first gear (32), and an engaging mechanisn (38) such as a cam ring. The second gear (36) is rotatably mounted on and axially slidable along the spindle and is biased preferably by a helical spring towards the first gear (32). The engaging mechanism (38) is rotatably mounted adjacent to and preferably about the second gear (36) in an axially slidable manner along the longitudinal axis of the spindle (34). The engaging mechanism (38) is configured so that rotational movement of the engaging mechanism (38) translates into an axial sliding movement. Rotational movement of the engaging mechanism moves the second gear (36) into and out of driving engagement with the first gear (32) depending on the direction of rotation.
