Abstract:
1. A motor driven saw comprising a gearing housing ( 4 ) with at least two housing parts ( 6 , 8 ), a stroke bar ( 10 ) that executes a stroke movement in a direction of a stroke axis ( 26 ) and a reciprocating movement generator ( 36 ) that can be turned on and off and by which the stroke movement is superimposed with a reciprocating movement executed transverse to the stroke axis ( 26 ), wherein the reciprocating movement generator ( 36 ) is supported on the gearing housing ( 4 ) in a preferred direction of advance ( 16 ) of the saw by bearing zones ( 30 , 44 , 62 ), wherein all bearing zones ( 30 , 44 , 62 ) are arranged on a same carrying housing part ( 6 ), and wherein the reciprocating movement generator ( 36 ) has a switching element ( 40 ) that is supported on bearing bolts ( 32 , 58 ) by guide devices ( 66 ) in an axial direction of the bearing bolts ( 32 , 58 ) and is displaceable in a plane vertical thereto, a guide piece ( 38 ) that is mounted in the gearing housing ( 4 ) rotatable about an axis transverse to the stroke bar ( 10 ) and placed in contact at the switching element ( 40 ) via a contact zone ( 54 ).
