Series HGW

Balancing Machine for Drive Shafts

Simple and safe operation
Modular design for various applications
Comprehensive protective and safety equipment for operators, machine and environment
High measurement accuracy through microprocessor-controlled measuring unit

Range of application

Horizontal, hard-bearing balancing machines series HGW are designed especially for low- and high-speed balancing of drive shafts in overhaul, repair operations and small production lots. A modular design provides flexibility to change or add components for other balancing tasks such as balancing electric armatures, drums, etc.

Design

Hard-bearing special balancing machine with horizontal rotor axis and semi-automatic operation.
The machine consists basically of: machine base, support pedestals with spindle bearings and vibration sensors, belt-drive with drive motor, control cabinet with measuring unit and drive controls, safety brackets and protective enclosure of the class C according to ISO 7475.

The dimensioning of the machine components permits balancing of a large rotor weight range and guarantees high availability, operational safety and long service life.
Special spindle bearings cover a large speed range and withstand high centrifugal forces, typical because of radial and axial clearances common in drive shafts.
The dynamometer principle for permanent calibration guarantees high balancing accuracy and can accommodate large initial unbalances.

Systems for correction of unbalance, e.g. through welding of weights or drilling can also be integrated.
Through the use of adapter flanges a number of different drive shaft connections to the spindles can be achieved.

The modular design of series HGW balancing machines also permits balancing of rotors with their own shafts, e.g. electric armatures, drums, etc., through additional roller bearing carriages.

Balancing machines series HGW come with an extensive range of safety equipment to prevent injury to operators and damage to the machine:
A bearing force monitoring system automatically disconnects the machine drive as soon as excessive vibrations are measured at the spindle bearings.
Rugged and stable safety devices designed to prevent injury to operators and damage to the machine in case of an accident (e.g. rupture of a joint).
The protective enclosure of class C 600 acc. to ISO 7475 for protection against accidental release of correction weights.
