A versatile, precision-machined device for demonstration of the causes and effects of vibration in industrial rotating machinery. 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 display is included. A system of indexing pins and CNC-machined pillow blocks 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 aids usefulness.
1/4 HP, DC permanent magnet motor.
SCR speed control.
Digital RPM indicator with magnetic pick-up.
Heavy-duty, formed-steel sub-base, with adjustable feet.
Three precision-machined, split pillow blocks allowing for bearing removal.
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.
