Critical Speed Investigation Apparatus- Engineering Lab Training Systems.
Technical Description
This benchtop unit is used to show the
resonance and critical bending speed on rotating shafts. The
construction of the rotor of a thin, flexible shaft and rigid weights
facilitates the theoretical comprehension. The rotor is held on the base
frame with pivoting bearings. The weights and bearings can be placed at
any location along the shaft and attached securely with quick-acting
clamps. It is driven by a flexible coupling. Two motor speeds can be
fine-adjusted and preset with ten-speed potentiometers. They are
controlled electronically and displayed digitally. It is possible to
switch speeds during the experiment as desired. A transparent protective
hood covers the rotating parts. A set of electrical vibration sensors
with clamping set is also available.
