9D716M Shredder shaft balancing machine
The 9D716M belongs to the 9D series and has the same design, benefits and features as the other machines in this series. The machine specializes in balancing agricultural parts, particularly chopper shafts, so it is slightly different from the standard 9D.
Machines of this model have an artificially low level of support sensitivity. This is due to the fact that they work more often with heavy parts, which have a large initial imbalance. In such cases, measuring a large initial unbalance is more useful than determining an accurate unbalance. In addition, agricultural machinery parts do not require high accuracy of measurement. A machine with reduced sensitivity is still accurate enough to be able to perform balancing to an accuracy class G1.
The second feature of the 9D716M balancing machines is the “axial drive”. The design of the shredder shafts is very peculiar and the use of a “belt drive” can be problematic due to the risk of damage to the drive belt by the shredder blades. The “axial drive” is safer to use in this case as the torque is transmitted from the motor to the shredder shaft by means of a cardan shaft adapter which is fixed to the end of the shaft journal.
Model 9D716M machines perform the following operations:
- Single-plane balancing of “disk” type parts (pulleys, gears, discs, etc.);
- Two-plane balancing of shaft-type components (shredder shafts, drums, beater, etc.)
- Selective balancing (separator drum, combine rotor, fan rotor, etc.)
- Quality control of the balance.
Machines of this model are often used in the repair shops of farms that operate different agricultural machinery. Also this equipment is popular among manufacturers of agricultural equipment.
- The ability to handle a large range of heavy parts with large initial imbalances not only allows you to cover all your balancing needs, but also to make good extra work on “outside orders”;
- Adaptability of the machine to all working conditions and to parts of different sizes, weights and constructions;
- Starting the measuring cycle at a speed of 400-600 rpm, we are able to work with details of low rigidity and considerable length, excluding the unintentional buckling caused by centrifugal force and gravity;
- By special order the machine can be made in a combined design and contain both “axial” and “belt” drive. This will increase the versatility, functionality and reliability of the machine.
Functions of the hardware-software complex PAK-1:
- Calculation of “permissible unbalance” Calculation of “permissible unbalance,” “test weight” and “drilling depth” eliminates the need for complex mathematical calculations and leaves this to the computer;
- “Vector averaging” reduces the measuring cycle and improves the quality of the balance by combining the differently directed unbalance vectors into one unbalance vector;
- “Unbalance distribution on the n-plane correction” provides the ability to reduce the volume and weight of the correction weight by dividing it into several smaller weights. A useful function if the design of the part limits the use of oversized correction weights;
- “Unbalance decomposition into constructional points” simplifies work with parts that are limited by their construction, e.g. the part has blades and the correction area is limited to them only;
- “Creating and printing a report on the balancing performed” provides quality control of the performance of this operation and eliminates disputes related to the quality of assembly (or manufacture) of the balancing part and the performed balancing.
