Abstract

1377552 Balancing reciprocating parts ACIERS ET OUTILLAGE PEUGEOT 6 March 1972 [1 April 1971] 10325/72 Heading F2X A balancing device for a hand tool, in particular a jig-saw, comprises two gear-wheels 20, 21 loosely mounted on a shaft 22 parallel to the shaft 1 of the electric motor M and carrying balancing weights 23, 24. The toothed end portion 4 of the shaft 1 meshes both with a gearwheel 5, which transmits the drive of the motor M to the tool carrying means 13, and the gearwheel 21 whereas the gear-wheel 20 only meshes with the gear-wheel 5. The gear-wheels 20, 21 may be made from a thermoplastic material in which case the balancing weights are secured to the gear-wheels. Where the gear-wheels are made from a metal or alloy of suitable density, the weights are in one piece with the gear-wheels. In either case, the gear-wheels have the same number of teeth and the same pitch diameter with corrections made to the teeth of the gearwheels such that their outside diameters are different. Thus the gear-wheel 20 of larger outside diameter meshes with the gear-wheel 5 whereas the gear-wheel 21 of smaller outside diameter clears the teeth of the gear-wheel 5. When the motor M operates, the toothed end portion 4 of the shaft 1 drives the gear-wheel 5 and the gear-wheel 21. The gear-wheel 5 drives the gear-wheel 20 in the opposite direction to gear-wheel 21 but at the same angular velocity.
