Fly-wheel transducer

Rotationsschwinger

Oscilador rotatorio

Came oscillante

Apart from the crank drive, the fly-wheel transducer is another possibility for electro-pneumatic hammers to transform the motor and transmission rotation into a stroke motion. The fly-wheel transducer is composed of:

- a shaft driven by the motor through a transmission.

- a ball bearing attached diagonally to a special arbor on the drive shaft

- a pivot which sits on the outer ring of the ball bearing, the ?tumble finger?

- a piston pin

- a piston

- a cylinder

When the shaft rotates, the ball bearing is set into a tumbling motion. The tumble finger slips into the piston pin and makes the piston execute a back and forth motion inside the cylinder.
