Static and Dynamic Balancing Apparatus- Engineering Lab Training Systems.
Technical Description
The main element of
the benchtop 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 is driven by a speed-controlled
motor. The 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. Using different
weights dragging on the pulley defined moments can be exerted to the
shaft. They can be compared with those caused by the unbalance weights
when rotating. The 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.
