Noise Behaviour:
- New concepts were applied to clearly improve the noise emission of the gear units
- Designing noise-absorbing case
- Achieving exceptionally large contact ratios
- All the gears have been grinded .
Thermal conduction:
Gear units not only have a high efficiency but also have a favorable thermal conduction
- Through enlarged housing surface areas;
- As large fans incorporating a new type of air conduction fan cowl are being used
- Selection of gear unit is based on a lower maximum oil temper ature .By that ,the operational
- reliability will be increased and the cost of maintenance reduced due to longer oil change intervals
Storing:
Gear units have been designed according to a new unit construction principle, which reduce the variety
