Manufacturing supporting devices for rotor balancing

Abstract

Rotor unbalance is one of the common causes of machine vibration. The unbalance
in rotor also transmits forces on the bearings and the foundation, reducing the life of
machine as well as causing vibrations at the workshop. A rotor is considered
unbalance when the weight of rotor distributes unequallythrough its centerline of
rotation. Generally, dynamic balancing machines are used to detect the location and
magnitude of the rotor unbalance based on the diagnostic of the rotor’s vibration in
operation. Dynamic balancing machines can be divided into two main categories: the
fixed balancing machine is normally installed on a foundation in a workshop. It is
used for balancing removed rotors or those not yet installed in machines; and the
portable balancing machine used for balancing rotors installed in machines without
removing them. In order to exploit the capabilities of portable balancing machines, in
this paper, we propose to manufacturebalance supporting devices that can be
combined with a portable balancing machine to balance removed rotors or those not
yet installed in machines. These supporting devices have the advantage of allowing
us to save money on purchasing of different types of balancing machines.
