Critical Speed Investigation Apparatus

Product Description

Critical Speed Investigation ApparatusTechnical description ofCritical Speed Investigation ApparatusThis 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.Specification ofCritical Speed Investigation Apparatus Benchtop experiment for investigating critical bending speeds on rotors Max.
