Chain saw, esp. an electric chain saw, combines advantages of belt drive and coupling without disadvantages of either coming into effect

摘要

The chain saw includes a belt transmission unit (25) having a separating clutch (34) which is disposed between the driven shaft of a motor and a sprocket wheel (26). A chain brake can be activated upon disengagement of the clutch. The unit has a belt wheel (30) which is disposed coaxially with the sprocket wheel. The clutch is located between the belt wheel and the sprocket wheel.
