Balancing machine for complete assemblies
HS 10 - 40 | HS 10 Twin

Range of application
Measurement of the unbalance of complete assemblies such as fan motors in medium to large batches.
Designed for standing or seated operator and for use in varying locations.

Change-over to a different rotor type can be achieved easily within a minimum of time.

Manual unbalance correction by addition of material (e.g. balancing plasticine or metal clips) directly on the machine or by removal of material on optional manually operated or semi automatic machine tools.

Design
Hard-bearing horizontal balancing machine of table-top design with one or two measuring stations. Designed for standing or seated operator with partly automated sequence of operations.

Microprocessor based measuring instrumentation with permanent calibration.

The two bearing pedestals are connected by means of a plate or a frame, accommodating an adapter/clamping device to support the assemblies.

The assemblies are driven by their own drive system through an integral power supply. Alternatively external drive by means of compressed air or belt drive can be used.

Many assemblies, particularly fans for use in vehicles or domestic appliances, gyroscope rotors or hard disc drives have to be balanced in the fully assembled condition.

Even if all individual parts are balanced carefully, assembly of the complete unit will create new unbalances, resulting from manufacturing errors, such as eccentricity, fit tolerances or concentricity errors.

The machine concept is particularly variable. Subassemblies are mounted on specially adapted plates which can be interchanged easily. Underslung belt drive can be used universally for a variety of rotors having their own shaft journals.

For larger batches, a two-station machine is the optimum solution. The machine can be operated in overlapping cycle, i.e. while the unbalance of one rotor is being corrected, the unbalance of the next one can already be measured. Likewise, the operating and safety concept is designed with a view to short cycle times.

Fan motors usually come equipped with power supply connectors or leads and can therefore be accelerated to operating speed most conveniently using their own drive system. A built-in power supply system makes contact with the motor and enables the assembly to be tested a operating conditions coming as close as possible to the actual operating conditions.
