Static and Dynamic Balancing | ProDynami 1268
Static and Dynamic Balancing ProDynami 1268 studies the balancing of rotating objects and the centrifugal forces that cause unbalance. This Static and Dynamic Balancing unit features a shaft with 4 adjustable unbalance weights, a speed range of 0 to 1400rpm, and digital speed display. Max. total unbalance is 840cmg, with big/small unbalance values of 110/55cmg and 30mm eccentricity. A transparent protective hood, integrated angle and length gauge, and elastic vibration-neutralizing base complete the approx. 30 kg benchtop unit.
The Static and Dynamic Balancing ProDynami 1268 unit is designed to study the balancing of rotating objects. This Static and Dynamic Balancing apparatus demonstrates how centrifugal force unbalances an assembly when an object rotates at a given velocity.
Product Overview
The Static and Dynamic Balancing ProDynami 1268 consists of a shaft supported by bearings on both ends. Four masses are present on this shaft, which can slide on the shaft and attain different angles. A pulley is present on one side of the shaft, connecting it to a motor so the shaft can be rotated. Two buckets, a detachable pulley and metallic balls are also included to find the unbalance in static position due to rotating masses. The motor is powered via a function generator. The main element of the bench top unit is a smooth shaft to which four variable unbalance weights can be attached at any angle or distance. The rotor is supported horizontally in ball bearings and driven by a speed-controlled motor. Speed is measured electronically and shown on a digital display. For determination of the unbalance weight by measuring the balance of moments, the driving belt can be removed. Different weights dragging on the pulley can exert defined moments to the shaft, which can be compared with those caused by unbalance weights when rotating. A transparent hood prevents contact with the rotating parts and provides a good view of the rotor. Fastening of the supporting base with elastic elements neutralizes undesirable vibrations. This Static and Dynamic Balancing unit illustrates the fundamentals of static and dynamic balancing on a benchtop scale.
