Static & Dynamic Balancing Machine

Static and Dynamic Balancing

The Static and Dynamic Balancing Machine is used to investigate balancing of a rotating system, using Dalby's Method. The apparatus is equally suitable for student experiments or demonstrations.
The bench mounted apparatus consists of a bal- anced steel shaft running in ball bearings held in a rigid chassis. The shaft has four balance blocks and is driven by a variable speed electric motor. The chassis has resilient mounts which allow the unit to vibrate for dynamic balancing.
The balance blocks can be clamped to the shaft in any angular or longitudinal position, these being indicated by precision scales. A set of special weights allows the weight of the balance blocks to be changed, thus greatly increasing the experimen- tal variations that are possible.
Static balancing is undertaken by a load pulley and extension shaft that fits into the end of the main shaft. A light cord and load hanger with a set of weights enables the moment of each balance block and additional weight to be measured in Nm.
The rotor assembly is driven by an electric motor for dynamic balancing via an elastomeric belt. A trans- parent safety guard covers the rotating parts and is interlocked with the machine electronic control unit. The guard design is such that the load pulley and extension shaft must be removed before it can be fitted.
The motor control unit, safety interlock items and tachometer are all built into the Static & Dynamic Balancing Machine apparatus. Thus the equipment only requires connection to the mains supply. 200-260/1/ 50-60Hz.
