B140-200K Series 90000 kg (200000 lb) Performance Specifications for Model B140 Balancing Machine 90000 kg (200000 Pounds) Capacity End Drive/Machining Type 1. GENERAL DESCRIPTION 1.1 The Model B140 is a dynamic, horizontal axis, soft bearing balancing machine. It uses moving coil transducers to measure the motion of an unbalanced rotor on freely moving suspensions. The machine must be firmly mounted to a standard reinforced concrete floor, but does not require any special foundation. In order to provide an easy to use transportable mounting method, track clamps are provided to lock the pedestals and console to an existing railroad track or an optional prefabricated railroad track bed assembly. The Model B140 has an End Drive console with a variable speed motor and multi-speed gearbox for efficient transfer of torque to the rotor. The End Drive system uses a cardan shaft (supplied) to spin the rotor. Adapters to attach the cardan shaft to the rotor are the customers’ responsibility. The use of a cardan shaft may require the use of electronic tooling compensation (a feature in the Model 295 instrument) to eliminate errors due to fit-up and/or unbalance in the adapter tooling. The machine and instrument are easy to set up and use. The standard calibration method uses trial weights to calibrate the rotor to the balancing instrument for the most accurate possible unbalance readout. The standard balancing instrument is the Model 295 which has large digital display meters and shaft synchronous digital filters. Dynamic (Left/Right), Static and Couple unbalance can be displayed, individual workpiece setups can be stored and the balance results can be printed on an external printer. The instrument also displays the angle position of the rotor to aid in placing the correction weights on the rotor. Detailed specifications on the 295 instrument are separate from these performance specifications.

The pedestals and console attach directly to any existing railroad spur, either flush with the floor or on top of the floor. If railroad track is not available, the pedestals and console can be directly lagged to the concrete floor. An optional Railroad Track Bed Assembly is available that provides the benefit of a railroad spur but with the advantage that it can transported with the machine and be placed on any concrete floor. Work Supports 3.2.1 Two super critical (above...

6.1 Foundation Requirements A normal reinforced concrete floor is recommended. No special heavy concrete substructure is required as long as the floor is capable of safety supporting the weight of the balancing machine plus its maximum weight capacity and does not permit any pedestal motion during the balancing operation. 6.2 Mounting Pedestals, console and optional railroad track, if used, must be secured to each other and the foundation to prevent movement during balancing. 7.
