This experimental unit demonstrates the conversion of smooth rotary motion into reciprocating motion. The input angle is set on a ball bearing mounted crank disc made of anodised aluminium and read off on an angle measuring scale integrated into the base plate. A millimetre scale is fitted for the outlet stroke. The crank radius can be adjusted in three positions. The simple insertion of a bolt enables the swivelling cylinder to be locked, thus a crank drive with either a fixed or oscillating cylinder can be demonstrated. The components are attached to a solid, painted base plate. Two handles make the unit easier to carry.
