Four Bar Chain Apparatus | ProDynami 1240
Four Bar Chain Apparatus ProDynami 1240 converts rotary motion into oscillatory motion using an anodised aluminium crank disc mounted on ball bearings. This four bar chain apparatus offers 3 crank radii (25mm, 37.5mm, 50mm), 3 swing radii (50mm, 100mm, 200mm), and 4 connecting rod lengths (160mm, 180mm, 200mm, 220mm). It is used to investigate mechanical relationships in four bar chain mechanisms and to check the Grashof set. The benchtop unit includes a white plate base with plastic feet and metal carrying handles.
The Four Bar Chain Apparatus ProDynami 1240 is a benchtop unit that converts rotary motion into oscillatory motion using a four bar chain model. This four bar chain apparatus is designed to investigate the kinematic behaviour of four bar chain mechanisms and to check the Grashof set.
Product Overview
The Four Bar Chain Apparatus ProDynami 1240 uses an anodised aluminium disc mounted on ball bearings as a crank. The disc has a scale so the input angle can be exactly measured. The crank pin can be set at different radii on the disc. The connecting rod and the oscillating lever are made of black anodised aluminium. They can be connected together in different lengths using easy to fit knurled bolts. The oscillating crank is attached to a disc fitted with an angle measuring scale. All components are fitted to a white plate fitted with plastic feet. The unit is placed on the laboratory table for the experiment. Two metal handles make the unit easier to carry. This four bar chain apparatus demonstrates the operation of axle pivot steering.
