An economical, yet versatile, precision-machined device for demonstration of the causes and effects of vibration in industrial rotating machinery. With the addition of optional or user-supplied diagnostic devices, the device allows for isolation of individual, vibration-causing variables in order to demonstrate their individual signatures. A permanent magnet DC motor with RPM pick-up and digital display is included. A system of indexing pins and CNC-machined pillow blocks, coupled with a t-slotted mounting surface, allows for convenient and accurate reconfiguration. The device and its associated course/exercise guide allows for introductory training in vibration cause/effect, balancing and data collection. Optional equipment can expand the training aid’s usefulness, in demonstrating expanded applications.

The device allows for observation and measurement related to the effects of mechanical looseness, critical speed, imbalance, bearing faults, and misalignment.
1/4 HP, DC permanent magnet motor, standard.
SCR speed control.
Digital RPM indicator with magnetic pick-up.
7-Gauge, Heavy-duty, formed-steel sub-base, with adjustable feet.
Two precision-machined, aluminum split pillow blocks allowing for bearing removal, and shaft repositioning
Two 6" precision-machined rotors, allowing for single plane, dual plane and overhung balancing.
Provision for creating rotor imbalance using set screws/washers or clay on inner rotor rim.
Two, ½" diameter, precision-ground shafts (allows for re-configuration).
Precision, helical beam coupling (other coupling types available as options).
Provision for attachment of vibration pick-ups via 1/4-28 threaded studs.
Modular, polycarbonate rotor and coupling guards.
Steel, top-surface mounting bars allowing for magnetic attachment of accessories, and modular guards.
Instructor key lock switch.
Motor mounting sub-base with tapered alignment pins, allowing for ease of alignment/mis-alignment.
T-slotted aluminum mounting surface allowing for convenient reconfiguration, and attachment of optional accessories.
Motor jacking bolts.
High-durability powder-coated and anodized surfaces throughout.
Packaging for shipment via motor freight.
