Analysis Of Balancing Machine Using 1-Axis Accelerometer

Abstract

- This paper presents an experimental design of balancing machine for the rotating
machine parts, like pulleys, fans, wheels, turbines, etc. The experimental result gives the
accuracy of the balanced parts. The system consists of a heavy steel frame, DC motor with
variable speeds (200-3500 rpm), shaft 25 mm diameter and 40 cm length, two pillow block
ball bearings, and coupling flange. The system work has the same principle technique of
dynamic response or vibration monitoring. An accelerometer is mounted on the bearing block
nearest to the test part, the sensor reads the vibrations at the running speed, and the data are
transmitted to Arduino type mega 2560, which sends the data of vibration to the laptop to
display it in Arduino software as signals data with time. In addition to that, a drill is used to
remove the spot which have a high mass. The result depends on the comparison between the
healthy conditions (rotating without any unbalanced part) and rotating with unbalanced part,
which has taken a mass from the high mass’s portion until becomes a perfect balanced part.
